Little tubs of poison don’t work. Empty-baited traps (in the hope they’ll just sort of sniff about a bit and get caught) don’t work.
The ultimate lure for mice? Toblerone. I’ve used the plain chocolate variety so far but have the white and plain chocolates to try as well. The poison and traps had been there for weeks without catching a thing. After rebaiting them last night, I caught three.
So now you know.
(I was going to post pictures of them up here, but I thought that would really be much too sadistic).
