I recently heard of this method which is recommended by Jerry Baker, 'Master Gardener'. Mix 8 oz. Spray this mixture on your entire yard. Sprinkling human hair all around the yard was also suggested. Because skunks wander from place to place there is a good chance that a skunk living under the house won't be there anymore a few days later.
Skunks only stay in one place for a long time when they are mostly inactive during the winter.
Young skunks may remain in a den while a mother searches for food during spring and summer months. Sometimes, however, one skunk may be under a home one day and a different skunk moves in the next, thus you may have an ongoing skunk problem if entrances aren't sealed. Skunks under a building This is one of the most common problems. If a skunk is under a building, it is best to wait until after dark and let the skunk leave by itself to seek food. Tracks at a den entrance will indicate that the animal has left.
