We have mice it seems everywhere around here. We had them move in under our house and we could hear them starting to get into the wall in the bathroom and then I found mouse droppings in my pantry. We used the Victor mouse traps, they are gone! I remember the first two days each one caught at least 2, some more. We used 4 of them in strategic places. and by the end of a week, no more signs, no more noises, and the traps are still open and waiting.
I have a mouse family out in the garden, near the coop. I know they aren't in the coop because I am out there once a week turning and pulling out litter in the coop. But I have found them living in the compost pile (before it all went to dirt) and in the old telephone poles we have. I think our yard just provides them somewhere to burrow. I have my feeder up, food sealed away.
