Here’s a photo of a frame of honey that’s been partially eaten by a mouse:

Here’s the view from the other side of the frame:

I had some frames of honey stored in a swarm trap in my shed and a mouse found a way in and probably came back night after night and had a feast.

THE FOLLOWING WAS UPDATED ON APRIL 05, 2014.

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:

13-12-23 Hungry Bees

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.

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.

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.

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…

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.

Damn.

We’ve had entrance reducers on all our hives for the past few weeks, and it doesn’t look like we can remove them any time soon because the wasps (a.k.a. yellow jackets) are everywhere. They’re constantly trying to get into the hives. Here’s a photo showing about six wasps blocking a ventilation hole (most of the screened holes in our ventilator rims are filled with wasps):

The next photo isn’t pretty. You’ve been warned.

THE FOLLOWING HAS BEEN UPDATED SINCE ORIGINALLY POSTED.

That’s right. I made a screened entrance reducer and it looks like this:

The wasps or yellow jackets hanging around our hives have become intense in the past few days. They’re constantly trying to get into the hives. I’ve added entrance reducers, but the entrance reducers also reduce the air flow (the hives don’t have screened bottom boards). The humidity builds up fast inside the young 2-deep hives when the sun comes out. So I made this screened entrance reducer from scrap wood, a piece of mosquito mesh, some duct tape and a piece of corrugated plastic from an old campaign sign I stole from a local politician who didn’t get re-elected. It’s just a prototype, but as you can see in the photo, the entrance has been reduced to about one bee-length while the bottom entrance space is still fully ventilated. Theoretically, it seems like a good idea. We’ll see how it works out.

UPDATE (Sept. 26/11): The screened entrance reducer works fine. Some of the bees get confused by the screen and it takes them a little longer to find their way back into the hive, but I doubt it holds them up any more than a solid entrance redcuer would. The general concept works. Now I just need devise as easier way to make them.

THE FOLLOWING HAS BEEN UPDATED SINCE ORIGINALLY POSTED.

I bought a wasp trap because wasps (or yellow jackets) have been showing up in larger numbers around our hives for the past week. The young hives could be at risk if we didn’t have entrance reducers on them. We partially reduced the entrances on the full hives. They should be okay. I bought the “Green Earth” Yellow Jacket Wasp Trap and Lure as extra production, though.

The plastic trap costs about $10, but it isn’t much good without the bait that cost another $6. (Not including the bait with the trap seems a bit deceiving to me.) I followed the directions and added apple juice and some meat (cat food) into the base of the trap. Then I added the $6 packet of wasp lure. Then I hung it up about twenty feet from the hives and hoped for the best. That was last weekend.

Just for the record, August in earwig month in Newfoundland. More and more of them are showing up under the top covers of our hives.

Some earwigs eat only plants and aren’t a problem for beekeepers. Other types of earwigs will feed on larvae and other protein rich goodies in the hive. I’m not sure what kind we have in Newfoundland, but to be safe, I squish them whenever I find them, which is just about every time I open a hive these days.
