To permanently exclude a skunk from your lawn, the best thing to do is find where the skunk makes its home. Typically this will be under decks, porches, or sheds. The best method is to close off entries to the skunks’ home. This can be done by laying down mesh, sheet metal, wood, or concrete. If you want to keep skunks from burrowing under fences, dig a trench around the fence and lay down ½” mesh to prevent the skunk from digging under the fence and coming into your yard. If the skunk burrows under your deck, place mesh in a trench around the deck to prevent the skunk from burrowing under the deck. If you notice a gap between the deck and the ground, block this entrance off. Once you block off entrances, make the lawn unappealing to skunks using the methods above, and the skunks will not want to come back.
