I had a squirell get into my genset many years ago and chew up the wiring harness. I don't like using bait traps because it attracts rodents to your coach. But I do use them once I know there inside. Now I use electronic sound devices (at least 2 of them) and, I took one day off bought a lot of course steel wool pulled out every drawer in the coach and anywhere else where I could get to a runway or cubby hole and stuffed it with very coarse steel wool! I haven't had a problem since. Good Luck to you and sorry to hear about your problem!
