Josie,

A couple of decades ago I bought an ultrasonic device that just plugs into an electrical socket. (I see that Mario has given you a link to one such device.) It's fantastic. I've never had mice, rats, possums, birds in eaves, etc., since. It takes a couple of weeks for the animals to work out that it's more comfortable not to be near the house. After that, they stay away and you'll never be plagued again.

Here are some on Amazon...

Ultrasonic Pest Repellers
