Moth balls or moth flakes. I once had a skunk move in under one of my rentals. The smell permeated right through the floor. I called animal control to remove it . They said they couldn't but that skunks, raccoons, etc don't like moth balls. So I threw a box of moth balls in the crawl space by the handful so they went every where. Sure enough within a day it was gone never to return. The next problem was getting all the moth balls out. They smelled just as bad.
Line your property with moth balls or flakes hell move on to a place that doesn't "smell" so bad.
