Mice ate our bees

Actually, I think not. Mice frequently move into a hive because it is warm and because there is a lot of food inside. But the food the mice are looking for is the honey and pollen, not the bees. Mice are certainly capable of ruining the comb, eating the honey, and causing the colony to starve, but they are pretty much vegetarians.

Sometimes the bees will do in the mice. I took the following photo several years ago in my top-bar hive. Nothing is left but the skeleton of the mouse, but bees are vegetarians too. They probably stung the mouse to death and then removed all the parts they could and dumped them outside. Occasionally, honey bees will enshrine a dead mouse in propolis instead of carting it away. The propolis covering prevents bacteria from spreading throughout the hive.

Wow, that is a crazy picture. I have had mice camping out and raising yong in the gable tops. They probably stayed warm from the heat of the colony below acting like a heat pad under their mattress.

Thanks so much for the visual…

My experience with mice is they do eat bugs. If you have ever found moth wings (from miller moths) that’s mice. They don’t eat the wings. They will also eat grass hoppers. So I would guess mice would eat bees too. And how convenient they are in a nice bunch in the winter.



Which is why I said mice are “pretty much” vegetarians—there are exceptions to everything. Still, I’ve seen many dead mice in hives. I believe if a mouse began eating live bees, the colony would emit alarm pheromone and that mouse would be good as dead, unless the colony was too small and/or too weak to defend itself. If the mice were just eating dead bees off the bottom board, that might pass.

In your experience, were the mice eating live moths and grasshoppers or dead ones?

I had pet rats (I know not the same, but similar) that were raised pretty much vegetarian, but when I put the occasional live crickets in their cage, they knew just what to do. So the killer instinct seems to be there.

I imagine they wouldn’t hesitate to eat brood given the opportunity, and I could imagine in an overwintering colony they could pick off some of the cold bees on the outside of the cluster and avoid getting stung. But the idea of them wiping out a whole healthy colony this way seems a bit far-fetched.
