Glad to hear the electronic repellants work. Our house up north has a mouse problem. Its a new house in the country and I'm so upset mice have found their way in. When we visited there last summer I plugged in an electronic thingee in every room. Didn't see any but it was summer and they come in when weather turns cold. We did go around the whole house and foamed every spot a pipe came in. We think they they are getting in from the garage. The walls and ceiling are dry walled out ther but there was a crack between the wall and celing. We trimmed out the ceiling with 2x2s so hopefully that stopped them. I want them gone!
