Okay, before I start my story...let me tell you first that I barely drive my car. So yesterday, I go to drive it (after about a week and a half) and I look in my back seat and notice that a tissue box I had back there was all chewed up and there was pieces of tissue all over my floor board and back seat. I looked all over (including in my engine bay) and saw no signs of them being around. I know mice can get in even the smallest spaces so I am assuming they either got in through my firewall or door or something. I know that this time of year, they are searching for places to nest for the winter. Anybody know of any home remedies to keep these bastards out?
