I get them living under the shed as well and trapping this is a PITA. I tend to catch everything but them, raccoons, cats, skunks.
I block off their holes with cinder blocks, and they just dig elsewhere. They drive me crazy.
I've tried piss, mothballs, various other urines, but they seem to just ignore it all.
I did manage to catch one once and took it over to a friend house who's a falconer and we let the hog run and unleashed the falcon after it. Nature at its finest.
