Good luck! We accidentally trapped one in the orchard last fall (trying for the raccoons). The tarp/blanket trick works great. I would rehearse the release part. My live trap turns out to have a terrible latch design that basically takes two hands, with no ability to have a long string pull it open. Fortunately, the skunk was very tolerant of the banging and muttered curses as I sorted out the latch. While it was waiting, it excavated down about six inches through the trap wires. It was rather impressive.
FWIW: There are some great how to videos on YouTube.
All the best,
Peter
