No one wants the nauseating smell of a skunk emanating from under a home but odor isn't the only reason to keep skunks away. The nocturnal scavengers regularly raid garbage, eat pet food and can make short work of a garden and landscaping. If you live in a mobile home, it's especially difficult to prevent skunks from living underneath it. Once a skunk has made a den, it's best to work quickly to remove it before it has a chance to give birth to more.
Shine a bright light under your home overnight. Skunks are nocturnal and the light may encourage the one under your house to find a more appealing nesting place.
Mix a solution of hot pepper and water, fill a garden sprayer and spray it liberally under the home. Repeat in intervals of two or three days until you are sure the skunk is gone.
Spray dog or cat repellent around the perimeter of your home and underneath it. Repeat every few days until you are sure the skunk is gone.
Dig a trench one-foot deep around the perimeter of your home. Spread a line of chalk or flour around the outside of the trench and wait until nightfall. When you see footprints in the chalk, signaling that the skunk is out foraging, install chicken wire around the perimeter. Extend the bottom of the wire into the trench and cover it over so that the skunk can't burrow underneath it.
Set a skunk trap if your local codes allow it. Use fish, fish-flavored cat food or peanut butter as bait. The trap must be small enough so that the skunk cannot raise its tail while inside and should ideally have solid walls so the skunk can't see outside it. When you trap the skunk, quickly cover the trap with a blanket if it doesn't have solid walls and lift it carefully. Relocate the animal a safe distance from your home.
