Mice have a natural aversion to mint, and will generally avoid it. Plant it around the exterior of your house as a deterrent as well as potting some around your home. Not only will they keep mice away, but theyÆll freshen the air as well. Ahhh. Spearmint seeds can be had in garden centers or ordered online


So you might try some mint extract or plants inside yer truck and other areas that they got into... <img src="/forums/images/graemlins/wink.gif" alt="" />
