Bees: The Risky Hive Split

Let’s see if I regret this.

I started my beekeeping hobby in June 2013 and have been blogging about it periodically. If you’re interested in reading the other posts in this series, follow the Adventures in Beekeeping tag. Keep in mind that the most recent posts always appear first on this blog.

Last week, I blogged about a hive inspection and included a photo of a queen cell. Because of its position in the frame, I thought it was a supersedure cell — the kind of queen cell the bees produce if their queen is ill, dead, or missing. But when I showed it to my beekeeper friends at last week’s bee chat, they universally agreed that it was a swarm cell. That meant my bees were planning to swarm.

I didn’t want that to happen. I wanted to increase the number of bees and especially beehives that I had — not decrease the number of bees.

Queen Cell
The elongated cell is definitely a queen cell, but is it a swarm or supersedure cell? People more knowledgeable than me say swarm.

I thought of everything I knew so far about beekeeping — which is pretty much based on what I’d read and observed for the past few months. (In other words, a lot but not much.) I reasoned that if the brood frames that included the swarm cells were removed from the hive without the queen and they were put in another hive, the bees would raise a new queen and I’d have a new hive.

This is a hive split.

I did this on Friday. I took two brood frames plus one honey frame from my first hive and placed them in a nuc box with two empty frames. All three frames were covered with bees that would become the new hive’s starting population. I’d rely on those bees to complete the rearing of the queens in the queen cells on those brood frames.

I then replaced the brood and honey frames I’d removed from the hive with empty frames, giving the bees plenty of space for new brood and honey in the existing colony.

The only problem: I never saw the queen.

Although I’m pretty sure she was left behind in the original hive, I can’t be sure since I didn’t see her. After all, the hive had to have at least 20,000 bees in it — finding one among all that is not easy.

And that’s where the risk lies.

You see, if I took the queen along with the brood frames containing the swarm cells, not only would I leave the original hive queenless, but I run the risk of losing a viable queen to the new queens that hatch. Or having bees swarm from the nuc anyway. (Admittedly, this second scenario is not likely, given the limited number of bees in the nuc box.) Finally, as my beekeeping friend in Vermont, Tom, pointed out, if a hive suddenly becomes queenless, the workers might start laying eggs. Those will all be worthless drones.

Of course, I did leave behind brood frames that included queen cells just in case. That hive runs the same risks.

Do I know what will happen? No. But time will tell. I’ll check the nuc box later today — it’s right here at my RV parking space — and try to figure out what’s going on. I’ll also check the original hive (which is down in Wenatchee) later in the week to see what those bees are up to.

Worst case scenario: I screw up my original hive and don’t have a viable colony in the nuc box. Best case scenario: my risky hive split works.

Will report back when I know something.

Bees: Installing Drone Frames

Trying natural varroa mite control.

I started my beekeeping hobby in June 2013 and have been blogging about it periodically. If you’re interested in reading the other posts in this series, follow the Adventures in Beekeeping tag. Keep in mind that the most recent posts always appear first on this blog.

Varroa mites are a real problem for beekeepers in the U.S. (and likely abroad). They breed on bee larva, sucking the “blood” out of their hosts and spreading throughout the hive. It’s impossible to prevent them from infesting a hive. The only thing you can do is try to minimize them and their damage.

A drone frame is a special brood frame with larger cells on the foundation. It’s part of a varroa mite control program. Theoretically, when the bees see these large cells they realize that they’re perfect for raising drones. Drones have only one purpose — to fertilize the queen — but they’re really not needed once the queen has been fertilized and is laying eggs. They’re larger bees and need larger cells to develop. They also take longer to develop, which is why varroa mites prefer infesting drone cells. So the idea is to encourage the bees to put only drone cells on one frame which, hopefully, will attract many of the mites in the hive. Then, before the drones hatch but after the mites have infested the drone cells, you pull the frame out of the hive and freeze it. This kills the drones (which, again, you really don’t need) and the mites. You then remove the caps from the drone cells and put the frame back into the hive where, hopefully, the process starts all over again once the bees have cleaned out the cells.

That’s the idea. I figured I’d give it a try, so I ordered two drone frames — so I could always have one in my hive, even when one was in the freezer. After getting the frames, however, I caught a swarm and started a second hive. So I’ve got one frame in each hive and need to get another pair to swap them out.

The photo below shows me inserting a drone frame into the bottom box of my first beehive. I pulled out a frame that was virtually untouched by the bees and moved that into the upper box in place of another untouched frame.

Adding a Drone Frame to a Bee Hive

I just hope I can fit the darn things in my freezer. Right now, I’m still living in my RV; eventually I’ll have my chest freezer out of storage and set up where I’ll have plenty of space.

I should mention here that using drone frames is part of an integrated pest management (IPM) system. I’ll use other control methods — such as a bottom board screen — when I settle my bees into their permanent home later this season.

Bees: A Closer Look

A look inside my first hive.

I started my beekeeping hobby in June 2013 and have been blogging about it periodically. If you’re interested in reading the other posts in this series, follow the Adventures in Beekeeping tag. Keep in mind that the most recent posts always appear first on this blog.

I did my third hive inspection on my first beehive the other day. My primary goals were to check the overall health of the hive, make sure there was fresh brood (unhatched bees), verify that the queen was present and healthy, see how far along the bees had come in filling the 20 frames in the hive, and replace one of the frames in the lower hive box with a drone frame.

I accomplished all of these things except spotting the queen. The hive seems very healthy, though, and the bees seem to be multiplying nicely, so I can assume that the queen is in there somewhere. The presence of several supersedure cells, however, hinted that the queen may be aging or that the bees might not have confidence in her continued viability. I find this odd because the bees came in a nuc I bought locally and the man who sold it to me installed a new queen not long before I bought it. So I’m not sure what’s going on there.

You can see a supersedure cell, along with quite a few drone cells, in the photo below. The supersedure cell is the elongated cell near the center of the image. The drone cells are the cells with the domed caps. Also in the photo are cells of capped and uncapped brood and stored honey. It’s interesting to note that I shot this closeup with my iPhone’s camera; I’m pretty surprised it was able to focus so closely — I did not zoom in, although I did crop the image.

Closeup of Brood Comb

Eight of the upper hive box’s ten frames were full of partially capped honey. One frame was in progress and the other frame was completely untouched. The sheer quantity of stored honey and the speed at which these bees seem to produce convinced me to add the Ross Rounds frames I’d assembled on July 4. I returned the next morning and added it atop a queen excluder and spacer with exit. With luck, they’ll fill and cap those frames before the end of the season.

More on drone frames in another post.
