Mice in the house.....eewwwww...I would be getting a cat or two! Females make the best micers. I have a mice problem on our back porch....but at least they haven't made it into the house. In the fall caught over 30 mice...when my son was home over Christmas had him do some extra door stripping...since have only caught 3 that still somehow gotten in. My traps are set in case spring mice decide it is time to check out the porch, but am hoping that they can't get in anymore...as I added a bit more stripping under a door where there was a small space. You need to find out where they are getting in and stop their entrances. I can be ok with them on back porch, but sure wouldn't want the mice in my house!
