Dealing with skunks under your house can be challenging. To effectively remove them, consider the following steps: inspect your property thoroughly to locate entry points, seal any openings with steel wool or caulk, remove potential food sources like pet food, secure your garbage, install motion-activated lights or sprinklers to deter them, and try using natural skunk repellents like peppermint oil or ammonia. If these methods fail, contact a wildlife control professional for assistance in safely removing the skunks.
