We have a mouse problem. They seem to be getting in through a hole in a pipe by the back door. The cat sleeps there and every morning we find a dead mouse. I have tried humane traps and a plug in. Neither works. Attempts to tape up the hole have not worked. We have found dead mice lying around who have evaded the cat and starved to death. I am sure there are more under the washing machine. What on Earth can we do??!! There are shoes in a rack there and they get in the shoes to get away from the cat.
