A skunk doesn’t need much of an opening. A gap under a deck or a loose piece of lattice is a front door. Once one settles in and has a litter, you’re dealing with smell, digging, and a whole family. Proofing your property before that happens is cheaper than dealing with it after.
Why it’s worth doing early
Skunks don’t dig their own dens. They take over spaces that already exist under decks, sheds, porches, and crawl spaces. A single female with a litter under your deck means months of odor and digging. Skunks can also carry rabies, and a dog that corners one under the porch is going to get sprayed in the face, which takes weeks to fully clear.
Find the entry points
Walk the property at ground level with a flashlight. Skunks don’t climb well, so focus on anything at or near the ground that a skunk could squeeze into.
- Deck and porch skirting. Check lattice for broken slats and gaps at the corners. This is the number one entry point.
- Foundation vents. Cover each with fine galvanized hardware cloth screwed into the frame.
- Sheds and outbuildings. Dirt-floor sheds are easy to dig under. Run hardware cloth around the whole perimeter.
- Concrete slab edges. Slabs settle and leave gaps that lead under the slab. Fill them, backed with mesh, not foam alone.
Use the right materials
Thin materials are a waste of time. A skunk has strong claws and will dig through chicken wire or chew through plain foam.
- Quarter-inch hardware cloth is the standard. Fine enough to block young skunks and tough enough they can’t tear through.
- Galvanized steel mesh works for bigger areas like a full crawl space perimeter.
- Concrete or mortar is the permanent fix for foundation gaps.
Bury it the right way
A skunk will dig under a barrier that just sits on the surface. Dig a trench and bury the hardware cloth, then bend the bottom few inches outward in an L-shape away from the structure. That outward bend is what stops them, they hit the buried mesh and can’t get under it. Bury it a foot deep if you want to be thorough.
Remove the food
Sealing helps, but skunks visit because something draws them. Bring pet food and water bowls in at night. Rake up spilled birdseed. Pick fallen fruit and harvest ripe produce. Use a closed compost bin and never add meat or dairy. Skunks also dig for grubs, so if your lawn is getting torn up, that’s usually the reason.
Don’t seal an occupied den
Before you seal anything, make sure it’s empty. Sealing a skunk inside means a dead animal or one that claws through your walls trying to get out. If the den is occupied, use a one-way door that lets the skunk leave but not come back, leave it a few days, then seal for good.
Skip the one-way door during spring and summer if there might be kits. They can’t follow the mother out and will starve inside. In that case wait, or call a professional.
Frequently Asked Questions
Not reliably. Strong smells may spook one briefly, but skunks adapt fast. Exclusion and removing food are the real fix.
They startle a skunk at first, but the animal quickly learns the light is harmless. Use them as part of a bigger plan, not on their own.
A motivated skunk can dig well under a foot. That’s why barriers need to be buried deep with an L-shaped footer.
Not like a raccoon. They can’t climb smooth vinyl or metal, but they can manage chain-link with big enough mesh. Use fine hardware cloth at the base.
It has limited effect and the smell fades fast, plus ammonia rags can hurt pets and kids. Proper exclusion is safer and works better.
At least twice a year, early spring and early fall, and after any big storm that might have washed soil away and opened new gaps.
