I wrote this last week during an extended lunch break and decided not to post it because it’s long and rambling and doesn’t say much about anything. But so what? Here it comes…
Have you ever walked towards your beeyard, sight unseen, and heard the deep hum of a swarm in flight? I have. I’m still not at the point yet where I’m 100% comfortable with swarms. I will always say this because it’s true: The best beekeeping day of my life was the day I caught a swarm on a farm in the country where my bees couldn’t stress out any humans who would then pass on their stress to me. Humans ruin everything.
The sound of a swarm in the distance should be exciting and fun for me (as it should for everyone), but it’s not. I’ve never fully recovered from the stress my neighbours caused me when they freaked out over one my colonies swarming past their back deck when I lived in the city. Although I live in a much more rural environment now, I have one particular neighbour whose kid’s swing set is not so far away from my beeyard. I single out the swing set because I imagine if my bees ever swarm, I know they’ll damn well land on that swing set — and I don’t know how my neighbour will react to that.
So when I came home after lunch yesterday and heard that oh so familiar hum that made me think, “Swarm,” I wasn’t 100% comfortable as I walked towards my beeyard. Would I find bees filling the air like in some ridiculous scene from the Old Testament? My thoughts were, “No, I’d rather not see that today, if you don’t mind.”
I freaked out a bit when I first saw a queen cup because I didn’t know what it was. I thought my bees were about swarm and that perhaps I should destroy the queen cups. But if a colony is about to swarm or replace its failing queen (two good reasons to create new queens), destroying the queen cups won’t make much difference. It could even make things worse.
A queen cup is the first stage of a queen cell, a big fat peanut-looking cell specifically designed for raising a new queen. The cell points down instead of sideways. Most honey bee colonies build queen cups just in case they need to create a new queen. But most of the time, at least if the beekeeper is paying attention, nothing happens. The cups are left unused.
I don’t destroy queen cups because they provide the easiest place to check for possible swarming. Here’s a quick video where I blab on about that.
The obvious clue is royal jelly or brood in the queen cups. But I’ve also noticed that the bees seem to clean and polish the insides of the queen cups in preparation for the current queen to lay in it, not unlike what they do with regular brood cells. Whenever I add a frame of drawn comb to a hive, the first thing the worker bees do is clean out every cell because the queen won’t lay in a dirty cell. Anyone who has ever observed a laying queen will have noticed that she sticks her head deep into every cell and inspects it carefully before she deposits the egg. If the surface of the cell isn’t shiny and clean, she moves on. I don’t know if anyone else has noticed the bees shining up the insides of the queen cups before a swarm, but I’ve seen it enough times to say, yup, that seems to be thing.
It was a hot day and the bees were sort of bearding at the bottom entrance. I’m not concerned about swarming because I checked this hive for signs of swarming about every two weeks for the past few months. I’d rather leave the bees alone, but I’d also rather not have to deal with swarms if I don’t have to. Anyhoo…
I also removed three frames of brood from the top deep about ten days ago and replaced them with empty drawn comb. I also pulled out a heavy frame of pollen from the bottom deep, one of several heavy frames that I found, and replaced it with a foundationless frame. And that’s why I’m not too concerned about this colony swarming any time soon, despite the fairly large number of bees floating around the front of the hive in the first video clip.
Removing the frames of brood reduced the number of bees in the hive, thus relieving congestion, giving the queen’s pheromones more room to flow around the hive and make everybody happy. Replacing the frames with empty drawn comb gave the queen room to lay, which is pretty much always a good thing. The foundationless frame in the bottom box gave the bees space to fill in, not just a blank frame of foundation, but actual empty space that they will be compelled to fill in to maintain the wonderful bee space that dictates the design of the best beehives all over the world. Building comb to fill in that space instead of building swarms cells — that’s what I want to see. Thus, I’m not concerned about swarming.
My plan is to leave this hive alone until the fall when I remove the honey supers. I may take a peek at some of the honey frames once in a while to see how they’re coming along, but the brood nest will be left untouched.
By the fall, the will have made two medium supers full of honey for me and will have enough honey in the brood chamber for themselves to stay alive all winter. That’s what I call good beekeeping… if it works.
Swarm Prevention by Not Overfeeding and Making Room for the Queen
In my experience, it’s important to constantly feed the bees during the first year (in Newfoundland), but it’s also important to stop feeding them at a certain point in the spring so they don’t swarm. When I find drone comb gunking up the bottom of the frames in the spring, that’s my cue that the colony could potentially swarm. Queens can’t mate without drones. That’s why the first swarms usually coincide with the flight of the first drones. I could be wrong about all of this, but from what I’ve seen with my bees, it’s true. A colony won’t swarm without drones.
If the bees have two or three solid frames of honey in every box — enough to prevent them from starving — and drone comb is present, then I stop feeding. I don’t feed my bees if they have enough honey on their own anyway, and unless it’s a weak colony, I don’t usually feed past May 31st either because there’s usually enough natural nectar sources available by then (in my local climate), especially in the city of St. John’s that is heavily populated by maple trees. I also check my hives at least every two weeks until the end of June to make sure the queen has room to lay. Most beekeeping (beyond feeding) can be summed up with that one sentence: Make sure the queen has room to lay.
For any first-year beekeepers in Newfoundland (or a similar climate) wondering what they might find during their first hive inspection of the year (which usually falls somewhere between late April and mid-May), here’s a video of my first hive inspection in 2011 that shows a fairly healthy colony coming out of winter, one that allowed me to steal a boat load of honey from it later that summer (though I may have had to feed it for a few weeks to give it a boost; I don’t remember).
I found honey on the outside frames, some pollen mixed in and then capped and open brood spread out over five or six frames in the middle. I might have been concerned with one or two frames of brood (though queenright colonies with zero brood as late as May 15th isn’t unheard of) but five or six frames of brood during the first week of May is pretty good for my local climate. (None of my colonies are doing as well this year. They’re still recovering from The Attack of The Shrews.) The hive body underneath was more or less empty.
These days I’m usually much faster with my inspections, but overall the video demonstrates how I still inspect (and reverse) my hives every spring. I have a more detailed video in the works, but for now I’ll break it down like this (assuming we’re dealing with a 2-deep Langstroth hive and it’s a warm, windless sunny day somewhere between 11am and 2pm): …
Hive inspections every two weeks aren’t always such a bad thing, especially for new beekeepers, because one of the best ways to learn what the bees are up to is to see what the bees are up to. (Collect that data!) I found an excuse to dig into my hives at least once a week during my first summer of beekeeping, and I learned more from my intrusiveness and observing everything up close and personal than I ever did from reading or watching the bees from a safe distance. Yes, there is a risk of disturbing the bees and killing the queen, but I was careful and gentle and made sure to put all the frames back the way I found them, and everything worked out fine.
Regular inspections also allowed me to remove comb and propolis that would have otherwise gunked up the frames and made future inspections messier, more difficult and perilous for the queen.
Messier — because comb connected between frames will often split open and scrape against honey in adjacent frames and spill honey all over the place. Drone comb, especially between brood boxes, is exceptionally gross when pulled apart.
Difficult — because frames that are bonded to the hive box with propolis don’t move. It requires careful maneuvering to pry out the frames with a hive tool — to snap off the propolis — and even then all the extraneous comb between the frames tends to squish bees and tear up honeycomb as well as brood comb along the way. Whereas frames that are cleaned up every two weeks can usually be pulled up with bare hands.
Perilous for the queen — because any comb between the frames or the brood boxes can easily trap and kill the queen (along with other bees) while the frames are being pulled out. (Some refer to this as rolling the queen.) Comb between the brood boxes leaves no space for the queen. If the queen is on that comb while a frame is slid back in, she’s dead.
I’ll try to update this post in the future with more detailed photos that illustrate what I’m talking about. For now, though, here’s a photo of a hive that I haven’t touched for almost three months.
Those frames are super-glued to the hive box with propolis and are held together by brace-comb as one big solid 10-frame block. Pulling those frames will be one seriously tangly experience (an experience I’m glad to have avoided during my first summer of beekeeping). …
SHORT VERSION: I was concerned when I saw a medium honey super suddenly crowded with bees. It turns that’s nothing to worry about.
LONG VERSION: I have one colony this year that isn’t in sad shape and might make some honey that I can eventually steal. The average high temperature for July where I live was 15°C (59°F), and that’s mostly with rain and fog. Honey bees that can make honey under such conditions are miracles workers. Yet I noticed bees in this one hive showing up in the honey super about a week ago and then today, just now, I found this above the honey super:
That’s a view of the bees through a screen at the bottom of an empty moisture quilt, essentially a screened inner cover and ventilation rim. Anyway, the bees are crowded up over the top bars in the honey super, pushing themselves into the screen of the empty moisture quilt. That’s a full blown cluster of bees, not just a few hundred workers showing interest in a honey super. …
It was about this time last year I walked in on a swarm. Turns out it was two swarms, but I managed to re-hive them and eventually got two new colonies from them, two colonies that were destroyed by shrews during the winter, but that’s another story.
I don’t recommend the bucket-and-dump method of re-hiving a swarm, but I had to act fast and didn’t have time to gather up the proper gear.
If I’d discovered the swarm cells a few days earlier, I would have prevented the swarm (in theory) by transferring the queen with several frames of bees to a new hive box, leaving the brood and swarm cells behind — essentially simulating the end result of an actual swarming. A queen emerges from one of the swarm cells left behind, then kills all the queens in the remaining swarm cells and eventually mates and all is right with the world. In theory.
I know some people destroy all but one or two of the remaining swarm cells, thus reducing the likelihood of swarm movement. I’ve also moved the brood and swarm cells to a new location instead and that seems to work in a pinch.
I’ve read about other methods of dealing with swarm cells, but they all seem too complicated to me, too much messing about. I like my method because it’s a simple one-time procedure and you’re done.
How do other people deal with swarm cells? If anyone still reads this blog, feel free to chime in.
When I reverse the brood boxes, usually some time in April, I don’t just pull the hive apart and reverse the positions of the deeps. (That’s an easy way to squish the queen, by the way.) I set up an empty deep next to the hive and, if it’s warm enough, carefully inspect each frame before I move it into the new bottom deep. No heavy lifting required. But more importantly, this allows me to assess the strength of the colony going into the new season and make adjustments on the spot if necessary. I will add drawn comb to the brood nest if the cluster looks like it needs room. I will add frames of honey or pollen if the bees are starving for it. I will give them frames of brood from another colony if they’re weak. In short, I will take whatever action is required to get the bees started on the right path for the new season.
Then for the rest of the year, because I know exactly what condition the colony was in at the beginning of the year, I’ll be able to assess the strength of the colony without having to dig into the bottom deep and disturb the brood nest every time I do an inspection. Are the bees filling frames in the top box with pollen? Is the brood nest straddling the deeps? I can tell a lot from looking down into a hive where the brood nest has been working its way up from the bottom.
It’s more difficult when the brood nest has been working it’s way from the top down. It’s more work, at least for me it is. I usually end up having to lift the top deep, essentially separating it from the bottom half of the hive, and potentially splitting up the brood nest, so I can see what’s going on in the bottom, to see how much the cluster has moved down and so on. In my book, that’s too much work and too disruptive. It’s much easier and less disruptive to the brood nest — if it’s seated in the bottom deep — to pull out a few frames in the top deep and look down to figure out what’s going on — and I never have to lift a deep or potentially split the brood nest if its straddling the deeps.
That’s why I reverse the brood boxes on most of my hives sometime in April. It doesn’t necessarily reduce the chances of a swarm, but it gives me an excuse to carefully inspect and assess the strength of the colony and perform future inspections with greater ease and less disruption to the brood nest.
I could be singing a different tune by this time next year, or even this time next week, but for now, this is where my experience with reversing the brood boxes has led me.
