Steve, I don’t like using bait that attracts rodents to your coach! But, I understand you need to eradicate them from your coach! I had them get into my genset and chew and destroy my wiring harness! After you get them out of your coach use double 00 steel wool. I bought mine at Lowe’s and I put the steel wool in every cubby hole that I could find. I even removed every drawer in my RV and put steel wool everywhere inside the drawer! I’ve never had a rodent inside my coach since and it’s been over 10 years! I’ve also used steel wool around my genset and haven’t had any trouble with it either.
