I have a garage that is attached to my house. I found that the mice were coming in through the frame at the bottom of the sides of the door. I stuffed steel wool in the holes on both sides and then filled it with that expandable foam insulation. I think I fixed it so that they can't get in but now how do I get rid of the ones that are already in the garage. I caught two in mouse traps. The other(s) figured out how to eat the peanut butter off the trap without snapping it. What can I do to get rid of them?
