I keep my truck in the garage at the cottage, but I put out lots of mouse traps and d-Con around. The down side to the d-Con was the first thing the kid's dog did was eat the stuff, so we had to get it to puke it up. I haven't had a mouse problem yet, but then again the $1,500. computer fix a couple years back was caused by something. They didn't say that it was rodent related, but I'm thinking that it could have been.
