The trap has caught three so far. After catching the mice I found more wrapper in a closet (didn't even know there was chocolate in there). Then today, as I was cleaning out a desk, I found this....
It is the shredded remains of an advent calendar that we were saving for Christmas. The kids said we were lucky when I found 7 pieces of chocolate that the mouse couldn't get because other stuff was on top of the lower part of the calendar. This is why you shouldn't eat anywhere else in the house and never stash food or candy anywhere but the kitchen. Mice will go for the good stuff and not just the grains.
