I spray foamed my landing gear gaps with the Pest Control expanding foam. Apparently it tastes terrible so critters donít chew through it. I was skeptical but 2 years later after sealing every nook and cranny with it Iíve not had a critter in the 5th wheel. We were at a campground that was a walnut forest and the squirrels there were horrendously overpopulated. There were two campers destroyed while we were there, we were thankfully spared or my sealing job worked well. Good Luck!!!
