Hey guys, wondering if you guys have any tricks for mouse proofing a camper. Last year we tried Irish Spring soap and dryer sheets, but that didn't bother the mice. This year we tried steel wool around all of the plumbing coming in from the floor as well as some peppermint scented packets. Looked the other day and have evidence of mice again. A couple of the packets have been chewed on. Steel wool seemed to be as I left it when the camper was put in storage. What do you guys do? Thanks!
