I was surprised to see some of my bees bringing in pollen today.
Honey bee bringing in pollen on October 25th, 2015 in Flatrock, Newfoundland.
Judging from the colour of the pollen, my guess is that it came from Japanese Knotweed. It could be Honey Clover too. I still see some of that around (what a fantastic plant that is). I saw bees from another hive bringing in yellow pollen, probably from Goldenrod, though it seems late for Goldenrod.
This is the first year I’ve used quarter-inch / 6mm mesh to keep shrews out of my hives. I was told to put the mesh on after the bees have stopped bringing in pollen because supposedly the mesh opening is so small that it knocks the pollen off the bees’ legs as they’re going through it. NOT TRUE. Every bee that came in with pollen today had no problem getting through with the pollen still intact. So…
I’ll put the mesh on during the first week of October for now on and not worry about it. Waiting any longer increases the chances of mice getting in, which I think already happened with at least one of my hives (the bees switched from being really nice to really mean overnight, but that’s another story). Drones can’t get through the quarter-inch mesh and the bees are having a hard time pulling out dead bees through the mesh, but I’m fine with that.
Postscript: I was wrong. Drones can get through the mesh. It’s not easy, but they can do it. Here’s some raw video footage that shows drones going through the mesh along with a few other things. The mesh is an obstacle for some of the bees, but overall I don’t think it’s doing much harm.
The best method I’ve discovered for killing wasps is to go out and buy one of these wasp traps:
Add some sugar water and a teaspoon of raspberry jam and then watch all the wasps / yellow jackets get trapped and die. (Sept. 22, 2015.)
Add a dollop of some sweet jam, pour in some water sweetened with sugar and then hang or place the trap some place where wasps are known to congregate. I put the trap out this morning and when I came home from work, it was full of wasps — hundreds of them.
Wasp trap filled with hundreds of yellow jackets in less than a day. (Sept. 22, 2015.)
I’ll continue to monitor the trap over the next week or two. I’ll stop using it if too many honey bees get trapped in it. Judging only from the first day I had the trap out, I’d say there’s one honey bee for every 100 wasps that get trapped in it. Scroll down to the bottom of this post for the latest results.

SHORT VERSION: When adding another hive body (or super) to a hive because the population is expanding and crowding all the frames, I try to pull up two or three frames of brood to reduce the chances of the queen becoming honey bound. I also surround each brood frame in the original hive body with blank or drawn comb to encourage the queen to fill them with brood. All of which may or may not reduce the chances of swarming.
LONG VERSION: Whenever I add another hive box (or deep) to a nuc or colony that’s population is expanding, I pull up two or three frames of brood while I’m at it because, on her own, the queen won’t always expand the brood nest up into a new deep. The worker bees fill it with honey instead and the queen becomes honey bound (or trapped in by honey with nowhere to lay), which can trigger a swarm, not something most beekeepers want.
Bees crowding all 10 frames. Perfect candidate for pyramiding. (August 2, 2015.)
Some people call the pulling up of brood pyramiding or creating an unlimited brood nest. It’s also similar to checker boarding. But it all seems like a variation on a theme to me. Pulling up brood encourages the queen to expand the brood nest up (not just to the sides), thus reducing the chances of her becoming honey bound.
The first frame from the edge full of bees and nectar. (August 2, 2015.)
So let’s say your deep has six frames of brood. You pull three frames of brood from the middle and then put a new frame (drawn comb, foundation or foundationless frame) between each remaining frame of brood, thus providing space for the queen to lay between the frames of brood. (The bees will have to build comb first if the new frames aren’t drawn comb, but that’s not bad because it gives the bees something else to do — fill in space with new comb — instead of preparing to swarm.) Then you add another deep and put the three pulled frames of brood in the middle, with empty frames on the sides. This new configuration of brood is in the shape of a pyramid and now the queen has plenty of room to lay in the lower and upper deeps (or hive bodies). Continue reading →
One of my cats killed a shrew near my hives today.
Dead shrew. (June 27, 2015.)
I lost 62% of my honey bee colonies to shrew predation last winter. No one ever warned me about them and I never noticed much written about them. You can expect me to write a Masters thesis on them by the end of the year, though.
I will be covering all of my hive entrances with quarter-inch mesh this winter.
One of my six colonies either has a mouse in the hive that’s scaring all the bees to the very top of the hive, or the colony is completely starved for honey. Either way it seems like most of the bees (and they’re grumpy) are clustered above the top bars and living entirely off dry sugar I added about a month ago. The bees are so crowded above the top bars, they’re constantly walking in and out around the top entrance, as can be seen in this photo I took during my lunch break today:
I also noticed many dead bees in the snow in front of the hive:
Not that dead bees in the snow are unusual, but none of the other hives have many dead bees nearby, hardly any. This does not bode well. Continue reading →
A mouse got inside my city hive because I waited too long to put on mouse-proofing mesh.
From what I can tell, the mouse (or mice) was in the hive for a long time and scared the bees, queen and all, into a honey super that I had placed above the inner cover during a late fall feeding. Continue reading →
A word of caution to beekeepers who use hard insulation in their hives for any reason: some ants have an appetite for insulation. Check out this photo sent to me from a beekeeper in Indiana:
I doubt this kind of infestation would be an issue for beekeepers on the island of Newfoundland or in similar climates (though you might want to look around for ant nests). Ants are usually long gone and out of sight by the time we have to put on insulation in November, or take it off in April. I suppose that’s a benefit of living in one of the chilliest, wettest, windiest places on the planet. Continue reading →
It went up to a stifling 11°C yesterday (52°F), so I took the opportunity to insulate our hives for winter and staple on some mouse-proofing mesh. This is as simple as it gets.
Hard insulation installed over winter-positioned inner covers (minus the top covers.)
The inner covers are in the winter position (with the convex side up, a.k.a. the flat side, which is misleading because both sides are flat, but basically you know it’s the winter position because it gives the bees more head space than when the “flat” side is down; anyway…). A piece of hard insulation is installed flat against the top of the inner cover. It covers the hole in the inner cover and you don’t have to make a tunnel for the bees through the insulation or anything because the bees have no problem getting outside through the upper entrance notch in the inner cover. Some beekeepers put duct tape over the inner cover hole so the bees can’t eat away at the insulation, but I didn’t use duct tape last winter and the bees didn’t get hungry for the insulation once. And that’s all there is to it. (See Making Insulated Inner Hive Covers for more info.) Just put the top covers on once the bees get out of the way, and you’re done.
The only problem with this method of insulation is that it doesn’t leave much space under the inner cover for feeding the bees candy cakes or pollen patties in late winter. To make that extra space, all you have to do is install a two or three inch rim (or an eke) under the inner cover. That’s what I plan to do. There are more than a few ways to insulate the hives for winter (moisture quilts, etc.) — and more importantly, to prevent condensation from building up inside the hives. This is just one of them. Along with wrapping the hives, it worked perfectly for us last winter. There are also plenty ways to feed the bees over winter (candy boards, etc.), but I can only talk from my own experience. Okay, then, let’s take a closer look at what I did yesterday… Continue reading →
We pulled four deep frames of honey from each of our hives this past summer to prevent the queens from becoming honey bound. We stored the frames in a cardboard nuc box and kept them in our house. Later in the fall we fed all but one of the frames back to the bees (see Feeding The Bees Honey Instead of Syrup). This morning I took a look at the remaining deep frame of honey stored in the nuc box and noticed it had mould growing on it.
