Had one of the little suckers get into the engine compartment of a Suburban I owned. He ate the wireing to the tune of $300 damage. After a lot of research I mixed up a spray bottle of 1/8 dishwash soap 3/8 water and 1/2 Hot Sauce (Texas Pete) spray on everything you don't want them on. when it dries, the soap makes it sticky and the sauce sticks to thier feet. They don't like it! they will stop coming around. Warning - it's caustic. The aluminum parts of my motor looked like theyed been dipped in acid. Real pitted. Had a hard time explaining to the buyer that it hadn't been in a flood. Dang squirrel also bit into the rubber part of my LP gas line. I always envisioned his little cheeks blowing out...
