Damage to RV while in storage by Rodents

Some good advice here. But one area i think needs addressing is where the weatherstripping is at the bottom (maybe even the sides) of the doors. I've gone all over the underside of my class B & this the one area i can't figure out, also the engine compartment. I've tried a lot of the ideas suggested & they seem to work, but that could also be because we haven't camped back in infested territory! I remember reading somewhere that mice can worm their way through an opening the size of a pencil, so it's not too big of a stretch to imagine them just pushing aside the weatherstripping that much.
