Synopsis : The Spring honey harvest, heavy supers, extra supers, clearers and the space all that spare equipment occupies. You always have too much … until you run out.
Introduction
It’s usually about this point in the season that I start running out of equipment – brood boxes, supers, clearers, frames, buckets, jars 1etc. Unusually, it’s not happened this year … yet. However, as I drove back home with a car bulging with weighty supers on Monday, it did make me think about the space needed for beekeeping.
Beekeeping requires quite a bit of space … both in area and height.
Is there a pastime that takes up more space?
Stray ox-eye daisy (Leucanthemum vulgare) in the apiary
Hot air ballooning perhaps? But the balloon is deflated and packed away when not in use, whereas unused supers take up exactly the same amount of space as those in use. They’re just in a different location.
Furthermore, for a significant part of the year, all those supers remain in teetering stacks waiting for the nectar to start flowing. They might only get used for 3 months a year.
And what about feeders and those other items that get used for a week or two a year, or in the case of clearers, only a day or two?
Synopsis : The colony needs to be broodless for effective oxalic acid treatment in winter. You might be surprised at how early in the winter this broodless period can be (if there is one). How can you easily determine whether the colony is broodless?
Introduction
In late spring or early summer a broodless colony is a cause for concern. Has the colony swarmed? Have you killed the queen? Since worker brood takes 21 days from egg to emergence, a broodless colony has gone 3 weeks without any eggs being laid.
You’re right to be concerned about the queen.
Of course, since you’ve been inspecting the hive on a 7-10 day rotation, you noticed the absence of eggs a fortnight ago, so you’re well on your way to knowing what the problem is, and therefore being able to solve it 😉 .
But in late autumn or early winter a broodless colony is not a cause for concern.
It’s an opportunity.
Are they rearing brood? Probably by now … it’s mid-January
In my view it’s a highly desirable state for the colony to be in.
If the colony is broodless then the ectoparasitic Varroa mites cannot be hiding away under the cappings, gorging themselves on developing pupae and indulging in their – frankly repellent – incestuous reproduction.
Urgh!
Instead the mites will all be riding around the colony on relatively young workers (and in winter, physiologically all the workers in the hive are ‘young’, irrespective of their age) in what is incorrectly termed the phoretic stage of their life cycle.
This is incorrect as phoresy means “carried on the body of another organism without being parasitic” … and these mites are not just being carried around, they’re also feeding on the worker bees.
A broodless colony in the winter is an opportunity because phoretic mites (whether misnamed or not) are very easy to kill because they’re not protected by the wax capping covering the sealed brood.
Total mite numbers surviving OA treatment depends upon the proportion in capped cells
And today’s post is all about identifying when the colony is broodless.
Discard your calendar
I’ve said it before 1 … the activities of the colony (swarming, nectar gathering, broodlessness 2 ) are not determined by the calendar.
Instead they’re determined by the environment. This covers everything from the available forage to the climate and recent weather 3.
And the environment changes. It changes from year to year in a single location – an early spring, a late summer – and it differs between locations on the same calendar date.
All of which means that, although you can develop a pretty good idea of when you need to intervene or manage things – like adding supers, or conducting swarm control – these are reactive responses to the state of the colony, rather than proactive actions applied because it’s the 9th of May 4.
And exactly the same thing applies to determining when the colony is broodless in the winter. Over the last 6 years I’ve had colonies that are broodless sometime between between mid October and mid/late December. They’re not broodless for this entire period, but they are for some weeks starting from about mid-October and ending sometime around Christmas.
Actually, to be a little more precise, I generally know when they start to be broodless, but I rarely monitor when they stop being broodless, not least because it’s a more difficult thing to determine (as will become clear).
Don’t wait until Christmas
A broodless colony is an opportunity because the phoretic mites can easily be killed by a single application of oxalic acid.
Many beekeepers treat their colonies with oxalic acid between Christmas and New Year.
It was how they were taught when they started beekeeping, it’s convenient because it’s a holiday period, it’s a great excuse to escape to the apiary and avoid another bellyful of cold cuts followed by mince pies (or the inlaws 5 ) and because it’s ‘midwinter’.
But, my experience suggests this is generally too late in the year. The colony is often already rearing brood by the time you’ve eaten your first dozen mince pies.
If you’re going to go to the trouble of treating your colonies with oxalic acid, it’s worth making the effort to apply it to achieve maximum efficacy 6.
I’m probably treating my colonies with oxalic acid in 8-9 days time. The queens have stopped laying and there was very little sealed brood present in the colonies I briefly checked on Monday this week. The sealed brood will have all emerged by the end of next week.
It’s worth making plans now to determine when your colonies are broodless. Don’t just assume sometime between Christmas and New Year ’will be OK’.
But it’s too early now for them to be broodless … or to treat with oxalic acid
If your colonies are going to go through a broodless period this winter 7 it’s more likely to be earlier rather than later.
Why?
Because if the colonies had a long broodless period stretching into mid-January or later it’s unlikely they’ll build up strongly enough to swarm … and since swarming is honey bee reproduction, it’s a powerful evolutionary and selective pressure.
Colonies that start rearing brood early, perhaps as early as the winter solstice, are more likely to build up strongly, and therefore are more likely to swarm, so propagating the genes for early brood rearing.
But surely it would be better to treat with oxalic acid towards the end of the winter?
Mites do not reproduce during the misnamed phoretic stage of the life cycle. Therefore, aside from those mites lost (hopefully through the open mesh floor) due to allogrooming, or that just die 8, there will be no more mites later in the broodless period than at the beginning.
Since the mites are going to be feeding on adult workers (which is probably detrimental to those workers), and because it’s easier to detect the onset of broodlessness (see below), it makes sense to treat earlier rather than later.
Your bees will thank you for it 😉 .
How to detect the absence of brood
Tricky … how do you detect if something is not present?
I think the only way you can be certain is to conduct a full hive inspection, checking each side of every frame for the presence of sealed brood.
Perhaps not the ideal conditions for a full hive inspection
But I’m not suggesting you do that.
It’s a highly intrusive thing to do to a colony in the winter. It involves cracking open the propolis seal to the crownboard, prising apart the frames and splitting up the winter cluster.
On a warm winter day that’s a disruptive process and the bees will show their appreciation 🙁 . On a cold winter day, particularly if you’re a bit slow checking the frames (remember, the bees will appear semi-torpid and will be tightly packed around any sealed brood present, making it difficult to see), it could threaten the survival of the colony.
And don’t even think about doing it if it’s snowing 🙁 .
Even after reassembling the hive the colony is likely to suffer … the broken propolis seals will let in draughts, the colony will have to use valuable energy to reposition themselves.
A quick peek
I have looked in colonies for brood in the winter. However, I don’t routinely do this.
Now, in mid/late autumn the temperature is a bit warmer and it’s less disruptive. I checked half a dozen on Sunday/Monday. It was about 11°C with rain threatening. I had to open the boxes to retrieve the Apivar strips anyway after the 9-10 week treatment period.
Recovered Apivar strips
I had repositioned the Apivar strips about a month ago, moving them in from the outside frames to the edges of the shrinking brood nest. By then – early October – most of the strips were separated by just 3 or 4 frames.
The flanking frames were all jam packed with stores. The fondant blocks were long-gone and the bees had probably also supplemented the stores with some nectar from the ivy.
Over the last month the brood nest continued to shrink, but it won’t have moved somewhere else in the hive … it will still be somewhere between the Apivar strips, and about half way is as good a place as any to start.
Apivar strip (red bars) placement and the shrinking brood nest
So, having removed the crownboard and the dummy board, I just prise apart the frames to release the Apivar strips and then quickly look at the central frame between them. If there’s no sealed brood there, and you can usually also have a look at the inner faces of the flanking frames down the ‘gap’ you’ve opened, then the colony is probably broodless.
It takes 45-60 seconds at most.
It’s worth noting that my diagram shows the broodnest located centrally in the hive. It usually isn’t. It’s often closer to the hive entrance and/or (in poly boxes) near the well insulated sidewall of the hive.
Hive debris
But you don’t need to go rummaging through the brood box to determine whether the colony is broodless (though – as noted earlier – it is the probably the only was you can be certain there’s no brood present).
The cappings on sealed brood are usually described as being ‘biscuit-coloured’.
Not this colour of biscuit
‘Biscuit-coloured’ is used because all beekeepers are very familiar with digestive biscuits (usually consumed in draughty church halls). If ‘biscuit-coloured’ made you instead think of Fox’s Party Rings then either your beekeeping association has too much money, or you have young children.
Sorry to disappoint you … think ‘digestives’ 😉 .
That’s more like it …
The cappings are that colour because the bees mix wax and pollen to make them air-permeable. If they weren’t the developing pupa wouldn’t be able to breathe.
And when the developed worker emerges from the cell the wax capping is nibbled away and the ‘crumbs’ (more biscuity references) drop down through the cluster to eventually land on the hive floor.
Where they’re totally invisible to the beekeeper 🙁 .
Unless it’s an open mesh floor … in which case the crumbs drop through the mesh to land on the ground where they’ll soon get lost in the grass, carried off by ants or blown away 🙁 .
It should therefore be obvious that if you want detect the presence of brood emerging you need to have a clean tray underneath the open mesh floor (OMF).
Open mesh floors and Correx boards
Most open mesh floors have a provision to insert a Correx (or similar) board underneath the mesh. There are good and bad implementations of this.
Poor designs have a large gap between the mesh and the Correx board, with no sealing around the edges 9. Consequently, it’s draughty and stuff that lands on the board gets blown about (or even blown away).
Good designs – like the outstanding cedar floors Pete Little used to make – have a close-fitting wooden tray on which the Correx board is placed. The tray slides underneath the open mesh floor and seals the area from draughts 10.
Open mesh floor and close-fitting Varroa tray by Pete Little
Not only does this mean that the biscuity-coloured crumbs stay where they fall, it also means that this type of floor is perfect when treating the colony with vaporised oxalic acid. Almost none escapes, meaning less chance of being exposed to the unpleasant vapours if you’re the beekeeper, and more chance of being exposed to the unpleasant vapours if you’re a mite 😉 .
Since the primary purpose of these Correx trays is to determine the numbers of mites that drop from the colony, either naturally or during treatment, it makes sense if they are pale coloured. It’s also helpful if they are gridded as this makes counting mites easier.
Easy counting …
And, with a tray in situ for a 2-3 days you can quickly get an idea whether there is brood being uncapped.
Reading the runes
The diagram below shows a schematic of the colony (top row) and the general appearance of debris on the Varroa tray (bottom row).
It’s all rather stylised.
The brood nest – the grey central circle is unlikely to be circular, or central 11.
The shrinking broodnest (top) and the resulting pattern on the Varroa tray (bottom)
Imagine that the lower row of images represent the pattern of the cappings that have fallen onto the tray over at least 2-3 days.
Biscuit-coloured cappings on Varroa tray
As the brood nest shrinks, the area covered by the biscuit-coloured cappings is reduced. At some point it is probably little more than one rather short stripe, indicating small amounts of brood emerging on two facing frames.
With just one observation highlighted should you plan to treat next week?
Let’s assume you place the tray under the open mesh floor and see that single, short bar of biscuity crumbs (highlighted above). There’s almost nothing there.
Do you assume that it will be OK to treat them with oxalic acid the following week?
Not so fast!
With just a single observation there’s a danger that you could be seeing the first brood emerging when there’s lots more still capped on adjacent frames.
It’s unlikely – particularly in winter – but it is a possibility.
Far better is to make a series of observations and record the trajectory of cappings production. Is it decreasing or is it increasing?
Multiple observations allows the expanding or contracting brood nest to be monitored
With a couple of observations 10-12 days apart you’ll have a much better idea of whether the brood area is decreasing over time, or increasing. Repeated observations every 10-12 days will give you a much better idea of what’s going on.
Developing brood is sealed for ~12 days. Therefore, if brood rearing is starting, the first cappings that appear on the Varroa tray are only a small proportion of the total sealed brood in the colony.
Very little cappings but certainly not broodless
Of course, in winter, the laying rate of the queen is much reduced. Let’s assume she’s steadily laying just 50 eggs per day i.e. about 12.5 cm2. By the time the first cappings appear on the Varroa tray (as the first 50 workers emerge) there will be another 600 developing workers occupying capped cells … and the worry is that they’re occupying those cells with a Varroa mite.
The cessation of brood rearing
In contrast, if there’s brood in the colony but the queen is slowing down and eventually stops egg laying, with repeated observations 12 the amount and coverage of the biscuit-coloured cappings will reduce and eventually disappear.
At that point you can be reasonably confident that there is no more sealed brood in the colony and, therefore, that it’s an appropriate time to treat with oxalic acid.
In this instance – and unusually – absence of evidence is evidence of absence 🙂 .
But my bees are never broodless in the winter
All of the above still applies, with the caveat that rather than looking for the absence of any yummy-looking biscuity crumbs on the tray, you are instead looking for the time that they cover the minimal area.
If the colony is never broodless in winter it still makes sense to treat with oxalic acid when the brood is at the lowest level (refer back to the first graph in this post).
At that time the smallest number of mites are likely to be occupying capped cells.
However, this assumption is incorrect if the small number of cells are very heavily parasitised, with multiple mites occupying a single sealed cell. This can happen – at least in summer – in heavily mite infested hives. I’ve seen 12-16 mites in some cells and Vincent Poulin reported seeing 26 in one cell in a recent comment.
Urgh! (again)
I’m not aware of any data on infestation levels of cells in winter when brood levels are low, though I suspect this type of multiple occupancy is unlikely to occur (assuming viable mite numbers are correspondingly low). I’d be delighted if any readers have measured mites per cell in the winter, or know of a publication in which it’s reported 13.
This isn’t an exact science
What I’ve described above sounds all rather clinical and precise.
It isn’t.
Draughts blow the cappings about on the tray. The queen’s egg laying varies from day to day, and can stop and start in response to low temperatures or goodness-knows-what-else. The pattern of cappings is sometimes rather difficult to discern. Some uncapped stores can have confoundingly dark cappings etc.
But it is worth trying to work out what’s going on in the box to maximise the chances that the winter oxalic acid treatment is applied at the time when it will have the greatest effect on the mite population.
By minimising your mite levels in winter you’re giving your bees the very best start to the season ahead.
Unrestricted mite replication – the more you start with the more you end up with (click image for more details)
The fewer mites you have at the start of the season, the longer it takes for dangerously high mite levels (i.e. over 1000 according to the National Bee Unit) to develop. Therefore, by reducing your mite levels in the next few weeks you are increasing your chances that the colony will be able to rear large numbers of healthy winter bees for next winter.
That sounds to me like a good return on the effort of making a few trips to the apiary in November and early December …
Synopsis : Now is the time to make plans for the long winter ahead; frame building, winter projects, some light reading or an escape to somewhere warmer and with better wine?
Introduction
The good late summer September weather1 has been replaced with the first of the equinoctial gales. Actually, more of a 30-40 mph stiff breeze with an inch or two of rain than a real gale. Nevertheless, wet and windy enough to preclude any outdoor jobs, and instead make my thoughts turn to winter projects.
The more northerly (or southerly) the latitude, the longer the winter is. Here in north west Scotland there’s virtually no practical beekeeping to be done between the start of October and early/mid April i.e. over 6 months of the year.
Some beekeepers fill these empty months by taking a busman’s holiday … disappearing to Chile or New Zealand or somewhere equally warm and pleasant, where they can talk beekeeping – or even do some beekeeping – and, coincidentally 2 enjoy some excellent wines.
Santiago, Chile, bee graffiti …
Others ignore bees and beekeeping for the entire winter and think (and do) something completely different. They build model railways, or practise their ju-jitsu or – if really desperate – catch up on all the household chores that were abandoned during the bee season.
They then start the following season relatively unprepared. Almost certainly, next season will be similar to last season. They’ll make similar mistakes, run out of frames mid-season and lose more swarms than they’d like.
Rinse and repeat.
Alternatively, with a little thought, some reading, a bit of effort and some pleasant afternoons in the shed/garage/lounge, they can both plan for the season ahead and prepare some of the kit that they might need.
As Benjamin Franklin said ”By failing to prepare, you are preparing to fail.”
Looking back to look forward
I’ve discussed beekeeping records previously (and should probably revisit the topic). My records in the early years were terse, patchy, illegible and of little real use, perhaps other than in the few days that separated colony inspections.
Better than nothing … just.
My records now are equally terse, but up-to-date and reasonably informative. I’ve got a numbering system for my colonies and queens that means they can be tracked through the season. The records are dated (rather than ’last Friday’) so I can calculate when important events – like queen emergence or mating – are due.
They’re also legible, which makes a huge difference. I could just about read my old scrawled pencil notes a few days after an inspection, but would have had no chance 5 months later.
By which time I’d have lost the little notebook anyway.
So, at some point over the next few months – sooner rather than later – I’ll look through my records, update the ‘queen pedigree’ table 3 and summarise things for the season ahead.
In the spring I’ll update a new sheet of records with a short note on overwintering strength/success and then we’ll be ready to go.
But, in reviewing the records I’ll remind myself about the things I ran out of, the timing of swarm control (when there’s the maximum pressure on available kit) and ideas I might have noted down on how things could have been done better 4.
Reading and listening
The winter is a great time to catch up on a bit of theory. Some beekeepers do exam after exam, pouring over Yates’s Study Notes until they can recite chapters verbatim.
I’ve done enough exams in my lifetime for … a lifetime, and have no intention of doing any more.
However, I’m always happy to do a bit of reading. I’ve currently got The Native Irish Honey Bee and Joe Conti’s The Hopkins Method … (which I’ll return to shortly) by my desk. I’m also partially successfully at keeping up with some of the relevant scientific literature 5.
A larger and more enthusiastic audience than usually seen at a beekeeping talk
There are also numerous winter talks available. Some are through local associations, others are available more widely. I ‘virtually’ attended one this evening where there were questions from as far apart as Orkney and Tasmania.
Of particular relevance to Scottish beekeepers, it’s worth noting that our association membership fees are usually significantly less than south of the border (probably because your SBA membership is separate), so you can inexpensively belong to a couple of associations and benefit from their talks programmes and – if you’re lucky – Co-Op purchasing schemes 😉
My attendance at these talks is less good than it should be, largely because I give a lot of talks each winter, but I instead benefit from the Q&A sessions which can be both entertaining and informative.
OK … enough theory
Theory is all well and good, but beekeeping is a practical pastime and just because it’s dark, cold, wet and windy, doesn’t mean there isn’t practical stuff you could be doing.
Competitive beekeepers will use the time to prepare the perfect wax block or bottle of mead for their – local or national – annual honey show.
I’m not competitive, and my wax is pretty shonky but I’ve had fun making (and more fun testing) mead 😉
But there are lots of other things to do …
The known knowns
By reading your comprehensive notes you will know that you ended the season with 5 colonies, that swarming started in mid-May but was over by early July, and that you’ve got one really stellar queen you’d like to raise 2-3 nucs from.
All of which means you are going to need a minimum of 60 new frames next season. These need to be ready before swarming starts.
Bamboo foundationless frames
How did I get to 60?
About a third of brood frames should be rotated out and replaced each season (~20). The nucleus method of swarm control uses the fewest frames, but you’re likely to have to use swarm control for all your colonies (~25). Then there’s a further 15 frames for the 3 additional nucs you want to prepare. Of course, if you’ve got lots of stored drawn comb 6 or you use double brood boxes, or Pagden’s artificial swarm method these numbers will be different.
The point is, you will need extra frames next season.
I’m ending this season with about 20 colonies and so expect to need over 200 frames next year, possibly more if queen rearing goes well. Some frames will be recycled foundationless frames but others will contain normal wired foundation.
And what about supers? 2022 was a good year for honey. If you had enough supers and super frames you’ll probably be OK in an average year.
Whether it’s average or not, it’s always easier to build the frames – well-fortified with tea and cake – in the winter, rather than in a rush as you prepare to go to the apiary.
Exactly the same type of arguments apply to any other routine piece of kit – broods, supers, crownboards, roofs, clearers. Buy or assemble and prepare them in the winter.
After Tim Toady try something new
A few weeks ago I introduced the Tim Toady concept. For just about any beekeeping activity, there are numerous ways that it can be completed. There must be dozens of different methods for swarm control or queen rearing, perhaps more.
Of course, however many methods there are, all – at least all the effective ones – are based upon the basic timings of brood development and of the viable fractions of the colony. These things don’t change.
The biology of the honey bee is effectively unvarying.
Queens take 16 days to develop, drones take 32 days (from the egg) to reach sexual maturity. A queen and the flying bees are a viable fraction, as are the nurse bees and young brood etc.
Despite being based around these invariant 7 biological facts, not all swarm control or queen rearing methods are equal. Certainly, the end results might be similar, but some methods are easier, use less equipment, need less apiary visits or whatever i.e. some methods probably suit your beekeeping better than others.
My advice about this plethora of different methods to achieve the same ends remains exactly what it was a month ago … learn one method really, really well. Understand it. Become so familiar with it that you don’t need to worry about its success 8.
And then, after a bit of winter theory, plan to try something different.
And the winter is the ideal time to build any new things you might need to try this alternative method next season.
Here are a couple of my past and current winter projects.
Morris boards
Probably 90% of my queens are produced using the Ben Harden approach. It was the method I first learnt, and remains the method I’m most confident with. I’ve found it a reliable small scale method for rearing queens.
But, as they say, ’familiarity breeds attempt’ (at something new) and I’ve always liked the elegance of the Cloake board. This is a split board with an integral queen excluder and a horizontal slide. You place it between the boxes in a strong double-brood colony. By inserting the slide, opening upper front and lower rear entrances and simultaneously closing the front lower hive entrance you render the top box temporarily queenless and enable it to get stuffed with all the returning foragers 9. The queenless upper box is now in an ideal state for starting new queen cells from added grafts.
Morris board
But most of my west coast bees don’t end up as booming double brooders … the standard Cloake board needs too many bees for my location.
Parallel Cloake boards
Which is where the Morris board comes in. It’s effectively two parallel Cloake boards. Paired with a ‘twinstock-type’ divided upper brood box (or two cedar nuc boxes) it works in the same way as the Cloake board, but only needs sufficient bees to pack a 5-frame nuc so is better suited to my native bees.
Here’s one I started earlier … a Morris board under construction
You can buy Morris boards … or you can easily build them. This was one of my winter projects in ’20/’21. I’ve used them for the last two years successfully and have been pleased with the results.
I don’t think I understand their use as well as the Ben Harden system … but I will. In particular, I have yet to crack the sequential use of one side, then the other to rear a succession of queens.
Portable queen cell incubator
This was my one big project last winter. Unfortunately, we had a shocker 10 of a summer on the west coast and it was rarely used. I did put a few queen cells through it successfully, but queen rearing generally was hit and miss (mainly miss) so it’s yet to prove its full worth.
Portable queen cell incubator version 2
This is version 2 of the incubator. I’m gradually compiling a list of opponents for version 3 11 that should correct a few things that could be improved – capacity, level of insulation, heat distribution – though the current incarnation is probably more than adequate.
Building – and testing, which actually took a lot more time – the queen cell incubator was a lot of fun. I discovered (and created 🙁 ) a series of problems that needed to be solved and, relatively inexpensively 12, enjoyed sorting them all out. I could work in my warm, well-lit workroom, drink gallons of tea, and dabble with 12V electrickery without endangering my life.
I’ve used it this season powered by a 12V transformer indoors, from an adapter in the car or from a battery with solar backup in the apiary.
However, to use it properly I need to rear more queens … which brings me to …
Queen rearing without grafting
Both the Ben Harden and Cloake/Morris board methods of rearing queens use a suitably-prepared colony in which young larvae are presented. Typically 13 these larvae are grafted from a suitable donor colony.
Grafting is perceived by some as a ‘dark art’ – though perhaps not exactly malicious – involving a combination of sorcery, spells, fabulous eyesight and rock-steady hands 14.
It isn’t, but this perception certainly dissuades many from attempting queen rearing.
Capped queen cells produced using the Ben Harden queenright queen rearing system
I find grafting relatively easy and routinely expect 80-90% ‘take’ of the grafted larvae. My sorcery and spells are clearly OK. However, in the future, my eyesight and manual steadiness/dexterity are likely to decline as I get older 15.
I’ve also been reading some papers on how the colony selects larvae to develop into queens. Their strategy isn’t based upon what they can see and pick up with a 000 sable paintbrush … funny that.
I’m therefore going to try one of the graft-free methods of rearing queen cells, and the approach I intend to use is the Hopkins method. Hence the part-read copy of Joe Conti’s book mentioned earlier.
The Hopkins method of queen rearing
This method involves the presentation of a frame of suitably-aged eggs and larvae horizontally over a brood box packed with young bees. Importantly I mentioned both eggs and larvae as, under the ‘emergency response’ colonies preferentially rear new queens from 3 day old eggs.
The resulting queen cells are cut from the frame and used to prime nucs or mini-nucs.
Even with my presbyopia and ’hands like feet’ I should be able to manage that 😉
The intention is to couple the Hopkins method with a 12-frame double-brood queenless nuc box which is subsequently split into several nucs for mating the new queens. And, if that wasn’t enough, I’m hoping I can integrate this with some swarm prevention for the donor colonies … time will tell.
All of that means I need some new kit 🙂
Before butchery photo … an eke being adapted for the Hopkins method of queen rearing
I purchased some Maisie’s poly nuc boxes, floors, feeders and ekes in the summer sales. In the winter I’ll spend some time butchering them with my (t)rusty Dremel ‘multi-tool’ to accommodate the horizontal brood or super frames (and a cell bar with grafts for good measure) before painting them a snazzy British racing green or Oxford blue 16.
More poly hive butchering
I’ve already done a little poly hive butchering this winter.
I’ve got about 20 Everynucs from Thorne’s. These are a thick-walled, well made nuc with a couple of glaring design flaws. However, I’m prepared to overlook these as, a) they’re relatively easy to fix, and b) they cost me a chunk of money and I’m loathe to spend at least the same amount again to replace them.
In addition, bees overwinter fantastically well in them.
Here’s one I prepared earlier … an overcrowded overwintered nuc in April
I’ve also got a few compatible feeders which are really designed for feeding syrup. You can add fondant, but the bees then need to follow a rather convoluted path to access it.
Everynuc feeder …
I decided to modify the feeders to allow both by fitting a syrup-proof dam about half way along the feeder and drilling some 3-4 cm holes through the resulting ‘dry’ side of the feeder 17 .
Wooden syrup-proof dam and holes in an Everynuc feeder
Fondant, ideally in a transparent/translucent plastic food container 18 is inverted over the holes and the bees have direct access to it, even in the very coldest weather.
Munchity crunchity … direct access to the fondant
The Ashforth-type syrup feeder still works if needed and I no longer need 8 gallons just to top up each nuc 19. Typically my nucs won’t need feeding in midwinter, but if they do I should be able to position the fondant directly over the cluster allowing them the best chance of reaching it.
Winter weight
This is a practical project carried over from last year. I’m interested in the changing weight of the hive as the colony segues from ‘maintenance’ mode to early season brood rearing. I’ve drawn some cartoon graphs where there’s a clearly visible inflection point, with the hive weight dropping much faster once brood rearing starts.
Hive scales
I’m keen to have some real data rather than just my crummy cartoons. I already have the tools for the job, my no expense spared madehive scales. Tests last year showed that these were pretty accurate; I was about 8% shy of the actual weight (which doesn’t matter a jot, it’s the percentage change in weight that’s critical) and, more importantly, produced readings that were reproducible within a percent or two.
However, last year I was thwarted by bad weather, a lack of Gore-tex and an unexpected delay in evolving gills. I’ve now bought a sou’wester and, in the name of science, am preparing to brave the elements every week or so to weigh half a dozen hives.
And in between all that lot I’ll be building frames 🙂 20

The changes I’ve made will enable some new things to be incorporated over the next few months, once I’ve got a bit of spare time and have built all of those frames 😉
Synopsis :‘Nature knows best’ sometimes doesn’t apply to your bees and a responsible beekeeper must intervene with a little tough love to rescue the situation.
Introduction
Beekeeping involves quite a lot of responsibility. It’s not a ’fit and forget’ pastime. You need to think about others that you (and your bees) share the environment with.
Or, at least, you should.
If you want an apiary in your small urban garden you need to consider the impact it will have on the neighbours. If your colony develops American foul brood you have a responsibility to inform the local bee inspector who will notify the National Bee Unit. They, in due course, send one of those dreaded 1‘Foulbrood Alert’ emails to other registered beekeepers in the immediate area.
But your responsibilities don’t end with the civilians (i.e. non-beekeepers) and beekeepers around you.
Common carder bee
Arguably they also apply to the other pollinators your bees will be competing with in the environment. Will a quarter of a million generalists (your bees) threaten the survival of the – often more specialised – local solitary or bumble bees? 2
And, just when you thought I’d run out of responsibilities to remind you about, there’s the responsibility you have to your bees.
They’re not pets, they’re not domesticated, but they are at least partially dependent upon us. For shelter, for food (at times) and for their health and wellbeing.
And that sometimes means beekeepers have to take tough decisions …
Tough love
The phrase tough love was coined by Bill Millikan in his 1968 book of the same title. It’s usually taken to mean the ’act of treating a [person] sternly or harshly with the intent to help them in the long run.’
I put ‘person’ in brackets because – on a beekeeping blog – I’m talk about bees.
Although some beekeepers love to dabble with their colonies, the reality is that – for the most part and for much of the season – they do a pretty good job of looking after themselves.
Our interventions are really for our benefit – checking for queen cells so the workforce doesn’t vamoose, adding supers etc.
However, things can go wrong. Either we mess up, or there’s some bad weather or bad luck or bad karma. Whatever the cause, the colony may be left in a state in which their long-term survival becomes much less certain. At that point the beekeeper may have to – or should – make a pragmatic decision that resolves the situation.
And that decision may have to involve some ‘tough love’.
Not intervening may risk the total loss of the colony. Intervening, even though it may involve some sacrifices, may well save the colony.
Frosty apiary
This topic is timely as we’re reaching that point of the year where active beekeeping must stop and the, seemingly-interminable, off-season starts. Colonies that look in a precarious state now may well not make it through to the spring. Indeed, if they look really precarious now, they might not survive the first few frosts.
However, similar pragmatic interventions may be needed at other times of the season. In the following paragraphs I’ll illustrate a few scenarios and possible solutions.
Failed queens
The queen is, or should be (!), the longest-lived bee in the colony. Many live a couple of seasons, and some significantly longer.
But all good things must come to an end, and at some point she’ll run out of sperm, or enthusiasm or whatever. Usually the colony realises things are amiss well before the beekeeper and, quietly and efficiently, stages a bloodless coup and supersedes her.
A lot of supersedure happens in late summer and early autumn. The first you know of it is that you find an unmarked and unclipped queen the following spring.
Very late season virgin queens
‘Very late’ is a subjective term and depends on your latitude, the number of drones that are still about and the weather. Here in Scotland my colonies have been turfing out drones for almost a month and it’s already feeling quite autumnal. Further south things might be very different.
If you do find a virgin queen scampering about the hive (very) late in the season you have a dilemma. Do you cross your fingers and hope she gets mated in the next few days, or do you accept that it’s unlikely, sacrifice her and unite the colony.
Many beekeepers do the former.
Ever the optimist …
But let’s be realistic for a minute. How long since the queen emerged? If the weather has been poor for a fortnight she might already be going a bit ’stale’ (and if the weather has been poor you can be pretty certain that drone numbers in the area will be seriously depleted).
Is there a good chance she can get out in the weather predicted in the next week? And is there then sufficient time for her to lay enough brood to populate the colony with good numbers of winter bees that will ensure its viability until spring?
If she’s already ageing, if the weather is a bit dodgy, or if there’s any real doubt about the chances of success, I would always sacrifice the queen and unite the remaining bees in the colony with a nearby strong colony.
Yes … she might get mated … but if she doesn’t the colony is doomed.
Late season cast swarms fall into the same category, except they already may contain too few bees to rear lots of autumn brood.
Very early season queen failures
Sometimes – though rarely – you find a colony with a failed or failing queen very early in the season. I barely ever see these as I’m not usually opening boxes until mid/late April, but I know some beekeepers are busy at least 4-6 weeks before that.
It’s too early in the year to have any queens of your own and an overwintered queen will cost megabucks. Adding a frame of eggs/larvae is a non-starter … there are no drones yet.
But buying a new queen is unlikely to be satisfactory (aside from the megabucks that is). If the queen failed (or started failing) weeks ago – for example, she never started laying again properly after a few weeks off late the previous year – the colony will be dwindling fast and are unlikely to be strong enough to build up for the season ahead.
In my view buying a queen – or using one of your own – in this situation is not sensible. Cut your losses. Get rid of the queen if she’s still present and unite the remaining bees with another colony.
This isn’t even an example of tough love … it’s more just plain common sense and economically prudent 3.
Mid-season queen failures
Sometimes you find a colony with a really patchy brood pattern. Perhaps the queen is running out of sperm, or she’s very poorly mated (with only a small number of drones).
Patchy brood & QC’s …
However, in this instance it’s obvious to the beekeeper, but not necessarily obvious to the colony as they’re showing no signs of superseding her.
As an aside, it’s worth noting that there may be other reasons than a failing queen for a patchy brood pattern. A very strong nectar flow can often result in the workers backfilling cells within the brood nest … give them more supers. It’s also been reported that a spotty brood pattencan be due to the colony, not the queen i.e. you transfer the queen to another colony and her laying pattern improves.
Again I’d argue that, whilst you could let events run their course, it is probably better to intervene and get things back on track. In this instance I’d cull the queen and requeen directly or unite the colony (if I was sure there was no disease). Alternatively, if I had no spare queens, I would leave them queenless for a week, knock back any/all the queen cells and add a frame of eggs from a ‘good’ colony in the hope – actually expectation – that they’d rear a better queen.
Why intervene? After all, there’s lots of the season left, the weather is good, there are ample drones about etc.
By intervening I’ve got reasonable certainty of the timing of things. If I let the bees make the decisions they might wait until very much later in the season … which takes us back to ’Very late season virgin queens’.
Laying workers
By definition, a colony with laying workers is queenless. Laying workers develop in the absence of pheromones produced by open brood (larvae).
The colony thinks it is queenright. Therefore, if you try and requeen it they usually kill the introduced queen.
Laying workers …
One solution is to add a frame of open brood to the colony, and then add another a few days later … and perhaps one more a bit later. The brood pheromone suppresses the laying workers in the hive 4 and, with a bit of luck, they will rear a new queen from the last frame of eggs/larvae you added.
But they might not. And if they don’t you will have to intervene or the colony will inevitably perish.
Don’t throw good brood after bad
Over the years I’ve more of less (because I still sometimes try!) learned that laying workers are a lost cause. The resources that must be invested – in time and in open brood – are insufficient to justify the success rate.
So, time for some tough love … I remove the colony from its stand and shake all of the bees off the frames in front of other strong colonies. I discard the frames and any brood they contain (this will almost all be bullet-shaped drone pupae in worker cells).
Frames showing the characteristic dispersed bullet brood of laying workers
The brood will perish as will some of the bees you shake out … but they were doomed anyway 5.
Do not unite a colony containing laying workers with a queenright colony. The former thinks it is queenright … that’s not going to end well. I would expect the queen in the recipient colony to be killed 6. For similar reasons, if I only had two hives and one had laying workers, you risk the queen in the ‘good’ hive if you shake them out.
If you have a colony heavily infested with mites in midseason (let’s not discuss why this happened) you could treat them with a suitable miticide, accepting that the treatment period is likely to be protracted and it may even preclude adding honey supers 7.
Remember, the majority of the mites will be busily munching on sealed brood. You either need to use a miticide that permeates the cappings – go back and read the last footnote – or you need to treat for at least a complete brood cycle (and usually longer).
A colony that has recently been subjected to a shook swarm
Alternatively, you can conduct a shook swarm on the colony and then treat with a vaporised (which would be my choice) or trickled oxalic acid-containing miticide like Api-Bioxal.
Divide and conquer
During a shook swarm you separate the adult bees (and the queen) from all the brood. The latter is discarded (that’s the tough love bit). Since you now only have adult bees and their phoretic mites you can, more easily, kill 95% of the mite population.
I’ve done this many times 8. The resulting colony builds up again really strongly and – most importantly – the Deformed wing virus levels remain low for the remainder of the season.
Again, by sacrificing the brood that carries the vast majority of the mites, the remainder of the colony is given a new lease of life and should flourish.
This approach needs either a good nectar flow or a gallon or three of thin syrup (and suitable weather for comb building). To build up quickly the colony must draw a full box of new comb. Give them every opportunity to do so.
Philosophy corner
In the examples above I’m suggesting sacrificing one component of the colony – the queen, the sealed brood etc. – to ‘save’ the rest of the bees.
Of course, I’m well aware that the individual bees in a colony only live a few short weeks. The queen is the exception and can live several years.
So, in the case of a late season virgin queen, if you sacrifice the queen the remaining bees are saved, but they’re going to perish pretty soon anyway (Stalin’s ‘A single death is a tragedy; a million deaths is a statistic.’ comes to mind – though he might not have said this anyway).
So, does it make any difference?
I’m outside my comfort zone here, but I think it does.
If you do nothing and the queen fails to mate the queenless colony will die overwinter. They’ll dwindle until the cluster is the size of an orange and then freeze to death … or something equally sad/tragic/heroic/pathetic/inevitable (take your pick).
If you intervene, remove the queen and unite them with another colony, the individual bees (you added) probably won’t make it through to the spring, but they will contribute to the strength – and therefore survival – of the colony you united them with. Their demise, whilst still inevitable, will have some benefit.
And what about sealed brood? 9 I think something reasonably similar applies. Varroa-exposed pupae will almost certainly die before or shortly after emergence anyway. High infestation levels – I’ve seen colonies with 20,000+ mites – mean the majority of the brood is probably doomed. I would therefore have few qualms about sacrificing the brood with the expectation of purging the colony of mites within a few days of the shook swarm.
Sustainable beekeeping
Michael Palmer titled one of his excellent talks The Sustainable Apiary. It is all about being self-reliant in your beekeeping. Don’t buy in queens, do overwinter nucs to make up for overwintering losses etc.
I think this sort of sustainability is a very worthwhile goal for a beekeeper. It means acquiring the skills to rear new queens (which doesn’t necessarily mean grafting, mini-nucs or any of that ’high tech’ stuff … it can be a whole lot simpler, yet extremely effective 10 ), to identify disease and treat according, and to manage colonies so that they remain strong and healthy.
But sustainability does not mean save everything at all costs. Significantly understrength colonies, failed or failing queens, laying workers etc. require some tough love so that your remaining colonies can thrive.
Overwintered virgin queen?
It’s worth remembering that a strong overwintered colony, that builds up well in spring, will almost always produce both a new nucleus colony and a honey crop. Rather than try and maintain a failing colony overwinter, investing time and resources (like frames of brood or bees to give it a spring ‘boost’) – remembering that it may well perish during the winter anyway – unite it in autumn and then split off a nuc during swarm control the following spring.
Everybody’s a winner 😉
The two hive beekeeper
If you only have one hive and it’s weak going into the winter, or the queen fails, or it develops laying workers, then almost all of the above isn’t going to help much. What’s more, if you’ve only got one hive, how can you tell that the colony is weaker than it should be?
It’s much easier to compare colonies in the same environment to determine if they are strong or weak.
Compare and contrast – much easier when you have something to compare with
This reinforces the importance of having at least two hives. If this was your first season I’d strongly recommend you aim to go into next winter with two strong colonies. If you’ve yet to start, remember that a single colony can reach a state in which it will inevitably perish, but you can almost always rescue things if you have a second hive 11.
As you embark on your last inspections of the season, don’t go into the winter with crossed fingers and a prayer for ’that little colony in the blue hive’ … it’s not too late to unite it with a neighbouring hive.
Synopsis : The large number of beekeeping methods is both a benefit and – for beginners particularly – a distraction. Learn methods well enough to be confident when you apply them. Understand why they work and their pros and cons.
Introduction
In an earlier life as a junior academic I was generously given a crushingly boring administrative task. The details don’t matter 1 but it essentially involved populating a huge three-dimensional matrix. The matrix had to be re-populated annually … and, when I was allocated the task, manually.
To cut a long story short I taught myself some simple web-database computer programming. This automated the data collection and entry and saved me many weeks of tedious work.
Geek alert …
This minor victory resulted in me:
writing lots more code for my admin and research, and for my hobbies including beekeeping and photography. It’s been a really useful skill … and a lot of fun.
inevitably being given an additional mundane task to fill the time I had ‘saved’ 🙁 2.
The programming language I used was perl. This is a simple scripting language, which although now superseded in popularity by things like python, remains very widely used. All proper computers 3 still have perl installed.
Perl is perfect for manipulating text-based records. The name is an acronym for ’practical extraction and reporting language’ … or perhaps ’pathetically eclectic rubbish lister’, the latter reflecting its use to manipulate text (‘garbage in, garbage out’ … ) 4.
Perl was (and remains) powerful because it’s a very flexible language. You can achieve the same goal in many different ways.
This flexibility is reflected in the perl motto: ’There’s more than one way to do it’, which is abbreviated to TMTOWTDI.
TMTOWTDI is a mouthful of alphabet spaghetti, so for convenience is pronounced Tim Toady … the title of today’s post.
Why?
Because exactly the same acronym could be applied to lots of things in beekeeping.
Ask three beekeepers, get five answers
But one of the five is wrong because it involves ’brood and a half’.
Anyone who has attended an association meeting and naively asked a simple question will understand the title of this section.
’How do I … [insert routine beekeeping problem here] … ?’
The old and the wise, or perhaps the old or the wise, will recommend a series of solutions. Some will offer more than one.
Each will be different.
Many recommendations will be perfectly workable.
A few might be impractical.
At least one will be just plain wrong.
How do I avoid brace comb?
Confusingly … despite all being proffered solutions to the one question you asked, many will appear contradictory.
Do you move the queen away (the nucleus method) or leave the queen on the same site (Pagden’s artificial swarm) for swarm control? How can they both work if you do such very different things?
Ask twelve beekeepers, get nineteen answers (ONE IN ALL CAPS)
Internet discussion forums (fora?) are exactly the same, but may be less polite. This is due to the absence of the calming influence of tea and homemade cake. At least one answer will include a snippy suggestion to ’use the search facility first’.
Another will be VERY VERY SHOUTY … the respondent either disagrees vehemently or has misplaced the CAPS LOCK key.
Actually, in many ways internet discussion forums are a lot worse … though not for the reasons you might expect.
It’s not because they’re populated with a lot of cantankerous ageing beekeepers and arriviste know-it-alls.
There are some hugely experienced and helpful beekeepers online, though they probably don’t answer first or most forcefully.
The internet is worse because the audience is bigger and is spread over a wider geographic area. This is a problem as beekeeping is effectively a local activity.
If you ask at a local association meeting there will be a smaller ‘audience’ and they should at least all have some experience of the particular conditions in your area.
Včelařské fórum … and something you won’t see on the BKF … a whole sub-forum on subsidies
But if you ask on Beesource, Včelařské fórum or the Beekeeping & Apiculture forum the answers may literally be from anywhere 6. The advice you receive, whilst possibly valid, is likely to be most relevant where the responder lives … unless you’re lucky.
Let’s consider a few of examples of Tim Toady beekeeping. I could have chosen almost any aspect of our hobby here, but I’ll stick with three that are all related to the position or fate of the queen.
Queen introduction
Perhaps this was a bad option to choose first. Queen introduction isn’t only about how you physically get the new queen safely into the hive e.g. in some form of temporary cage. It’s also about the state of the hive.
Is it queenless? How long has it been queenless and/or is there emerging brood present? Is the brood from the previous queen or from laying workers? Is it a full hive or a nuc … or mini-nuc?
Successful introduction …
And it’s about the state of the new queen.
Is she mated and laying, or is she a virgin? Perhaps she’s still in the queen cell? Is the queen the same (or a similar) strain to the hive being requeened? Is she in a cage of some sort? Are there attendants in the cage with her?
And all that’s before you consider whether it’s ‘better’ to use a push-in cage, a JzBz (or similar) cage or to omit the cage and just rely upon billowing clouds of acrid smelling smoke.
Uniting colonies
This blog is nothing if not ’bleeding-edge’ topical … now is the time to consider uniting understrength colonies, or those headed by very aged queens that may fail overwinter.
Uniting two weak colonies will not make a strong colony. However, uniting a strong with a weak colony will strengthen the former and possibly save the latter from potential winter loss (after you’ve paid for and applied the miticides and winter feed … D’oh!). You can always split off a nuc again in the spring.
All the above assumes that both colonies are healthy.
There are fewer ways of uniting colonies than queen introduction, and far fewer than the plethora of swarm control methods.
This is perhaps unsurprising as there are fewer component parts … hive A and hive B, with the eventual product being A/B.
And does the queenright hive go on top or underneath?
And how do you prevent the bees from fighting, but instead allow them to mingle gently?
Or do you simply spray them with a few squirts of Sea breeze air freshener, slap the boxes together and be done with it?
Swarm control
If you find queen cells in your colony – assuming they haven’t swarmed already – then you need to take action or the colony will possibly/probably/almost certainly/indubitably 9 swarm.
The primary goals of swarm control are to retain the workforce – the foragers – and the queen.
There are a lot of swarm control methods. Many of the effective ones involve the separation of the queen and hive bees (those yet to go on orientation flights) from the foragers and brood. Some of these methods use unique equipment and most require additional boxes or split boards.
Split board …
But there are other ways to achieve the same overall goals, for example the Demaree method which keeps the entire workforce together by using a queen excluder and some well-timed colony manipulations.
confused.com
And then there are the 214 individual door opening/closing operations over a 3 week period (assuming the moon is at or near perigee) needed when you use a Snelgrove board 10.
Like any recommendation to use brood and a half … my advice is ‘just say no’.
Just because Tim Toady …
… doesn’t mean you have to actually do things a different way each time.
The problem with asking a group – like your local association or the interwebs – a question is that you will get multiple answers. These can be contradictory, and hence confusing to the tyro beekeeper.
Far better to ask one person whose opinion you respect and trust.
You still may get multiple answers 😉 … but you will get fewer answers and they should be accompanied with additional justification or explanation of the pros and cons of the various solutions suggested.
This really helps understand which solution to apply.
Irrespective of the number of answers you receive I think some of the most important skills in beekeeping involve:
understanding why a particular solution should work. This requires an understanding of the nitty gritty of the process. What are you trying to achieve by turning a hive 180° one week after a vertical split? Why should Apivar strips be repositioned half way through the treatment period?
choosing one solution and get really good at using it. Understand the limitations of the method you’ve chosen. When does it work well? When is it unsuitable? What are the drawbacks?
This might will take some time.
More hives, less time
If you’ve only got one colony you’ll probably only get one chance per year to apply – and eventually master – a swarm control method.
With more colonies it is much easier to quickly acquire this practical understanding.
Lots of learning opportunities here
Then, once you have mastered a particular approach you can decide whether the limitations outweigh the advantages and consider alternatives if needed.
This should be an informed evolution of your beekeeping methods.
What you should not do is use a different method every year as – unless you have a lot of colonies – you never get sufficient experience to understand its foibles and the wrinkles needed to ensure the method works.
Informed evolution
If you consider the three beekeeping techniques I mentioned earlier – queen introduction, uniting colonies and swarm control – my chosen approach to two of them is broadly similar to when I started.
However, as indicated above, there are still lots of subtle variations that could be applied.
With both queen introduction and uniting colonies I’ve more or less standardised on one particular way of doing each of them. By standardising there’s less room for error … at least, that’s the theory. I now what I’m doing and I know what to expect.
In contrast, I’ve used a range of swarm control methods over the years. After a guesstimated 250+ ‘hive years’ I now almost exclusively 11 use one method that I’ve found to be extremely reliable and fits with the equipment and time I have available.
It’s not perfect but – like the methods I use for queen introduction and uniting colonies – it is absolutely dependable.
I think that’s the goal of learning one method well and only abandoning it when it’s clear there are better ways of achieving your goal. By using a method you understand and consider is absolutely dependable you will have confidence that it will work.
You also know when it will work by, and so can meaningfully plan what happens next in the season.
So, what are the variants of the methods I find absolutely dependable?
Queen introduction
99% of my adult queens – whether virgin or mated – are introduced in JzBz cages. I hang the queen (only, no attendants) in a capped JzBz cage in the hive for 24 hours and then check to see if the queenless (!) colony is acting aggressively to her.
If they are not I remove the cap and plug the neck of the cage with fondant. The bees soon eat through this and release the queen.
Checking for aggression
I used to add fondant when initially caging the queen but have had one or two queens get gummed up in the stuff (which absorbs moisture from the hive). I now prefer to add it after removing the cap. The queen needs somewhere ‘unreachable’ in the cage to hide if the colony are aggressive to her.
It’s very rare I use an alternative to this method. If I do it’s to use a Nicot pin on cage where I trap the queen over a frame of emerging brood 12.
Nicot queen introduction cages
I use this method for real problem colonies … ones that have killed a queen introduced using the JzBz cage or that may contain laying workers.
Almost all colonies are united over newspaper. A sheet to two of an unstapled newspaper is easy to carry and uniting like this is almost always successful.
The brood box being moved goes on top. I want bees from the moved box to realise things have changed as they work their way down to the hive entrance. That way they’re more likely to not get lost when returning.
An Abelo/cedar hybrid hive … uniting colonies in midsummer
I don’t care whether the queen is in the upper or lower box and, if there’s any doubt that one of the colonies isn’t queenless, I use a queen excluder over the newspaper. I then check the boxes one week later for eggs.
I’m not absolutely certain one of the colonies is queenless
At times I’ve used a can of air freshener and no newspaper. This has worked well, but it’s one more bulky thing to carry. I also prefer not to expose my bees to the chemical cocktail masquerading as Sea breeze, Summer meadow or Stale socks.
Since uniting doesn’t necessitate a timed return visit there’s little to be gained from seeking alternatives to newspaper in my view. Perhaps if I lived in a really windy location I’d have a different opinion … placing the newspaper over the brood box can be problematic in anything more than a moderate breeze 13.
Swarm control
Like many (most?) beekeepers I started off using the classic Pagden’s artificial swarm. However, I quickly ran out of equipment as my colony numbers increased – you need two of everything including space on suitably located hive stands.
I switched to vertical splits. These are in essence a vertical Pagden’s artificial swarm, but require only one roof and stand. If you plan to merge the colonies again i.e. you don’t want to ’make increase’, vertical splits are very convenient. However, they can involve a lot of lifting if there are supers on the colony.
Vertical split – day 7 …
Now I almost exclusively use the nucleus method of swarm control. Used reactively (i.e. after queen cells are seen) it’s almost totally foolproof. Used proactively (i.e. before queen cells are produced) also works well. In both cases the timing of a return visit to reduce queen cells is important, and you need to use good judgement in deciding how strong to make the nuc.
Here’s one I prepared earlier
The nucleus method has a couple of disadvantages for my beekeeping. However, its ease of application and success rate more than make up for these shortfalls.
Tim Toady is ‘a good thing’ …
I love the flexibility of perl for programming. I can write one-liners to do a quick and dirty file conversion. Alternatively I can craft hundreds of lines of well-documented code that is readable, easy to maintain and robust.
Others, in the very best tradition of Tim Toady, might write programs to do exactly the same things but in a completely different way.
The flexibility to tackle a task – the three used above for example, or miticide treatment, queen rearing, uncapping frames or any of the hundreds of individual tasks involved in beekeeping – in different ways provides opportunities to choose an approach that fits with your diary, manual dexterity, available equipment, preferences, ethics or environment.
In this regard it’s ‘a good thing’.
Choice and flexibility are beneficial. They make things interesting and, for the observant beekeeper, they provide ample new opportunities for learning.
… and a distraction
However, this flexibility can also be a distraction, particularly for beginners.
That is why I emphasised the need to learn the intricacies of the method you choose by understanding the underlying mechanism, and the subtleties needed to get it to work absolutely dependably.
Don’t just try something once and then do something totally different the next year 14. Use the method for several years running (assuming it’s an annual event in the beekeeping calendar), or at least on a lot of different colonies.
Choose a widely used and well-documented method in the first place 15. Read about it, understand it and apply it. Tweak it until it either works exactly as you want it to i.e. reliably, efficiently, quickly or whatever, or choose a different widely used and well-documented method and start over again.
Get really competent at the methods you choose.
Once your beekeeping is built upon a range of absolutely dependable methods you have the foundations to be a little bit more expansive.
You can then indulge yourself.
Explore the options offered by Tim Toady.
Things might fail, but you always have a fallback that you know works.
