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. Here’s a photo of a frame of honey that’s been partially eaten by the mouse:
Here’s the view from the other side of the frame. You can see how the mouse chewed through the plastic foundation and the wood of the frame.
Slivers of wood left behind in the swarm trap:
And here’s the swarm trap (without its cover) in case you didn’t know what I was talking about:
Now might be a good time for me to mouse-proof my hives (here in eastern Newfoundland).
June 2019 Postscript: I shrew-proof (and by default mouse-proof) my hives with 6mm / quarter inch mesh these days.
I think that will be one of my chores over the next couple of days
I put the mesh / mouse guards on my hives two weeks ago and I can already see where a mouse has tried to get in one of the hives. I only hope I got the mesh on early enough. I was too late for at least one of my hives last year.
