Your going to have to use a bait trap to get then out! I prefer not to use bait traps because it draws them to your coach, but once there already in you have to get them out. I don't like using Decon because it makes rodents thristy and they may chew thru one of your water lines to get water, especially under the flooring. I haven't had rodents in my coach in 5 or 6 years. Once I got them out I bought 2 electronic noise devices. I keep one plugged in (inside the coach) the front end of the coach and the other plugged in at the rear of the coach. I also went to Lowes and bought double 00 very coarse steel wool. I took out every drawer in the coach and stuffed steel wool in every crawl space that I could or runway or open space. Did the same with the under storage areas. Any place that I could find a opening I used steel wool. I also used steel wool around my Genset! Rodents got in there one time and chewed up my wiring harness and other wires it was over $1,000.00 repair. I don't worry about it anymore. Good Luck, in the method you choose.
