I get a lot of calls with issues like this, and they have turned into 15k worth of damagaes to their main wiring harnesses. All the home remidies unfortunately will not work. You need to park In A garage if at all possible when the rodent pressure is high. If you can’t park inside, the best defense is poison stations next to your tires and around any outbuildings. Yes this will be a pain to move them every time you take off and park, but better than mouse damage.
