I once paid for have a heart trap folks to come out and trap four adult skunks that liked to borrow under the front porch, stairs and deck and hang out in the parking lot. $400 to have them trapped and moved elsewhere ... at least 10 miles away they said. Then I had wire mesh and barriers installed at the foundations and tried blocking off all the entrances.
The next morning just after sunrise I was drinking coffee out on an upper deck and watched a mama skunk and her 5 babies trotting down the embankment toward the front porch and disappear. It's as if I hung out a VACANCY sign for new skunks..
