Recently, I read one suggestion about how to keep mice & rats from entering an RV; it consisted of placing metal ducting around each tire. The idea is that the ducting is too slick for them to climb and too high for them to jump onto. Being placed around each tire, it prevents them from climbing up the tire treads, then into the RV via whatever entrance they can find. However, the person who posted this excellent-sounding idea didn't really give any details about just what kind of ducting he was talking about, other than saying that he got it at Lowe's. Does anyone on this forum have any experience with this method? If so, I would appreciate hearing from you as to just what kind of ducting is being used, here, and exactly how it is done. Any help would be much appreciated.
