We live in the country and store our RW in a pole barn. The dadgum satanic rodents chewed the wiring harness up in our pickup twice in six weeks while stored in that barn. They also made entry into our previous RV. I used steel wool in the places where plumbing came up through the floor and I ordered a gallon of 'Rat-B-Gone'. It cost about twenty bucks back then. The primary ingredient was 87% sulfur as I recall. I went to the feed store and bought a fifty lb. sack of sulfur and sprinkled on the ground surrounding the wheels, landing gear, etc. I also have fed the mice. I have tried a lot of products but love the green 1 1/2in cubes at Home Depot. I built a couple of boxes that had the bait at the far end of the box and a small entryway so raccoons, squirrels, dogs, etc. couldn't get to the bait. It seems to be working.
Re: the radio playing.....I had rats in the wellhouse. I turned the radio on to a station that plays Mexican music and cranked it up. The evil vermin preferred a different station and moved out!
