I have been told mothballs might work.......also a high pitched whistle used for dog calling.........humans can't hear this but skunks can............just figure out a way to keep this blowing for a length of time...........also contact your local humane society they might have solutions...........I am in the process of all this crap right now too......I am building an addition and they/it (skunk) has moved into the crawlspace under the new floor deck.........nice.....little rascal...
