My experience with skunks - Had a nest of them under my front porch (poured concrete). I ran a hose from my lawn mower exhaust to the opening and let mower run for about 30 minutes then filled the opening with dirt. No more skunks and surprisingly no dead animal odor. About two weeks later there was a faint skunk odor for a couple of days. Later (several years) another den of skunks dug under the poured concrete floor of my work shop from the gravel floor of the adjoining machinery shed. For a while I had skunks everywhere. I finally run the garden hose into the den. Out came a soggy skunk and never did return. They do not like a wet bed. Actually they are rather interesting to watch as long as you do not excite them. I could go into the machinery shed and see some then just rustle my foot around in the gravel and they would take cover for a while. I have been lucky not to excite one to the point of self defense.
