mice prevention?

[flatcreeker]

A cat is the best prevention. When my neighbor had horses and barn cats, I never had a mouse. They got rid of the horses and the cats and now I have mice. I bait and trap year round. I have heard that placing fresh mint inside the car, under the seats, etc. will keep them away. I'm gonna try that soon. Oh, and I'll keep trapping. I live in the woods. You live in the woods you'll have field mice. Period. Just gotta keep them out of the '39 Merc.
