I have tried something new. A friend suggested mole deterants. They are a pointed cylinder with batteries inside, that you are supposed to stick in the ground. I just lay them in the cars, where they touch metal. Every 38 seconds or some such odd figure, they vibrate and make a noise, like someone making a high pitched raspberry with their lips. I have one in the tudor that has been going for over a year. It is supposed to annoy the critters so they leave. The intermittant noise seems to be the key, as they supposedly dont get used to it. I got mine at the garden center.
Another thing I did to discourage the mice from stealing cotton from the seats, is to cover the back side of the seat cushions with fine hardware cloth (wire fence) so they cannot easily get to the cotton.
