So-called legitimate sources (including RV dealers) suggest a variety of ways to repel rouge rodents. Says one, "Put Bounce dryer sheets in your cabinets and outside compartments." Tell that idea to the RVers who tried it and later found the mice discovered that Bounce dryer sheets can make for an excellent mouse nest in an RV after the little characters shredded the "repelling" dryer sheets.
Another piece of well-meaning--but useless--advice: Install an "ultrasonic pest repeller" in your RV and send the little rats scurrying before they even get inside. Once again, numerous college and university researchers respond: Save your money--ultrasonic repellers just don't work. What's the problem? The issue is that the repelling systems just don't have enough power. The sound level meant to run off rodents is just to small to get around blocking objects (furniture, walls, cabinet doors, and the like). It's kind of like driving down the road an being annoyed by a siren--roll up the window. Rodents just re-route in your RV, using objects to block the obnoxious noise.
The tried-and-true method to keep rodent invaders at bay boils down to blocking their entry. Carefully inspect your RV looking for spaces where critters can come in. Typically spots around where water, sewer, or gas lines pass through walls and floors may provide a little mouse easy access. Stuff any such crack (it doesn't need to be big for a mouse to get through) with steel wool, then cover with sealant.
