Do ultrasonic mouse reppellants work?
can not help you with the question regarding the ultrasonic mouse repellents, but i say the get a kitty. where i live a few people i know got mice when they was knocking down a lot of the houses, they tired everything from poisens to traps,one couple even ripped the floor boards up and chucked broken bottles under them to kill the mice, some worked to a degree but was a slow time getting rid of them.
