Getting rid of a skunk den is a two-phase process: first, you encourage the skunk to leave on its own, then you seal the entry points so it can’t come back. Rushing to block the entrance while a skunk is still inside will trap a panicking animal under your structure, which ends exactly as badly as it sounds. The key is patience, proper timing, and permanent exclusion barriers that prevent the problem from recurring.
Confirm the Den Is Active
Before you start any removal work, make sure a skunk is actually living there. A faint musky odor near the entry point is one of the most reliable signs, even when the skunk hasn’t sprayed. During late winter breeding season (February through March), males spray while fighting over females, so a stronger smell during those months is a near-certain indicator. You may also notice shallow, cone-shaped holes in your lawn where skunks have been digging for grubs at night.
To confirm the den is occupied and figure out when the animal comes and goes, sprinkle a smooth layer of flour about an eighth of an inch thick right in front of the suspected entrance. Check it shortly after dark. Skunk tracks in the flour mean the animal has left for the night, and that’s the window you’ll eventually use to seal things up. If the flour is undisturbed night after night, the den may already be abandoned and you can skip straight to exclusion.
Timing Matters: Avoid Kit Season
Skunks breed in late February through March, and females give birth in May. The young stay in the den for about three months before dispersing on their own, which means kits typically leave by August. If you discover a den in late spring or early summer, you’re almost certainly dealing with a mother and babies. Sealing the entrance during this period will trap flightless, nursing kits inside, where they’ll die and create a far worse odor problem than the skunk itself.
The safest windows for eviction are early fall (September through October) after kits have left, or late winter (January through early February) before breeding begins. If you’re stuck dealing with a den during kit season, your best option is a one-way exclusion door that lets the mother leave to forage but prevents her from returning. She’ll then relocate her young on her own. More on that below.
Encourage the Skunk to Leave
Skunks prefer dark, quiet, undisturbed spaces. Making the den uncomfortable is often enough to convince them to relocate voluntarily. Place a bright work light or a shop light aimed directly into the den entrance, and leave it on continuously. Skunks are active at dawn, dusk, and overnight, so constant light disrupts their sense of security. Adding a portable radio tuned to a talk station near the entrance provides irregular noise that further unsettles them. A rag soaked in ammonia placed near (not inside) the opening adds an irritating smell.
Combine all three deterrents at once for the best results. Most skunks will vacate within a few days. Use your flour tracking patch each evening to confirm whether the animal is still coming and going or has stopped returning entirely. Once you see no tracks for two or three consecutive nights, you can move to permanent exclusion.
Install a One-Way Exclusion Door
If light and noise aren’t enough, or if you need the skunk out during a sensitive period, a one-way exclusion door is the most reliable humane option. These are simple wire mesh or plastic devices that mount over the den entrance and allow the skunk to push out but not re-enter. You can buy them pre-made or build one from hardware cloth shaped into a tube with a hinged flap on the exit end.
Attach the door securely over the entry point, making sure there are no gaps along the edges. Leave it in place for at least a week, checking your flour patch nightly. Once you’ve confirmed no animal has returned, remove the door and seal the opening permanently.
One critical step before installing: make sure there’s only one entrance. Walk the full perimeter of the structure during daylight and look for any other gaps, holes, or soft soil that could serve as a secondary entry. If you find additional openings, seal all of them except the one where you’ll mount the exclusion door.
Seal the Den Permanently
This is the step that actually solves the problem long-term. Without proper exclusion barriers, a new skunk (or raccoon, or groundhog) will move into the same space within weeks. Skunks can dig a foot down, a foot across, and a foot back up to get under a foundation, so surface-level barriers won’t hold.
The most effective method is an L-shaped buried wire mesh barrier. Here’s the process:
- Use the right material. Half-inch galvanized hardware cloth is the standard. Chicken wire is too flimsy and will be torn through or rusted out within a season.
- Mark your digging line. Measure 1.5 feet out from the base of the structure and mark it with spray paint or a garden hose.
- Dig the trench. Excavate along that line to a depth of about 12 inches. The trench should run the full length of any vulnerable side of the structure.
- Shape the L. Cut your hardware cloth so it’s tall enough to reach from the bottom of the trench up to the base of the structure (the vertical part), with an extra 12 inches that bends outward along the bottom of the trench (the horizontal foot). This horizontal section is what stops diggers. When a skunk tries to burrow down at the structure’s edge, it hits the wire, digs outward, and hits more wire.
- Secure and backfill. Attach the top edge of the hardware cloth to the structure using screws and washers or masonry anchors, depending on the material. Then backfill the trench with the excavated soil and tamp it down firmly.
For decks and porches with visible gaps between the ground and the deck boards, attach hardware cloth vertically across the opening and extend it into the buried L-footer below. The goal is a continuous barrier with no gaps larger than three inches anywhere along it.
Deal With Lingering Odor
Even after the skunk is gone, the den area may smell for weeks. Skunk musk is an oily compound that clings to soil, wood, and concrete. A mixture of hydrogen peroxide, baking soda, and liquid dish soap creates a foaming reaction that breaks down the oils on contact. Mix it fresh and apply it immediately while it’s still actively foaming. Don’t store this mixture in a sealed container, as the gas buildup can cause it to burst.
The limitation of this DIY approach is that it only works when you can apply it directly to the affected surface. For hard-to-reach areas under decks or crawl spaces, commercial odor neutralizers designed for skunk musk are more practical. These products chemically break down the odor compounds rather than masking them, and they can be applied with a fog machine that reaches into tight spaces a spray bottle can’t. Without any treatment, skunk odor under a structure typically lingers for two to three weeks before fading on its own.
Know the Legal Restrictions
Trapping and relocating skunks is regulated at the state level, and the rules are stricter than most people expect. In New York, for example, it’s illegal to live-trap a skunk and release it anywhere other than the property where it was captured. Relocating wildlife can spread diseases like rabies (skunks are one of the primary carrier species in North America), and most states require a licensed nuisance wildlife control operator to handle trapping and relocation. In some states, skunks taken during closed trapping seasons must be euthanized and buried or cremated immediately.
Check your state wildlife agency’s website before setting any traps. In many cases, the exclusion approach described above is not only more humane but also the only option that’s clearly legal for a homeowner to do without a permit.
When to Call a Professional
Professional skunk removal typically starts around $150, with costs increasing if the job requires multiple trapping visits or installation of steel exclusion barriers around a large structure. Most jobs involve ground-level cage traps and take several service visits over the course of a week or two. If your den is under a concrete slab, in a crawl space with limited access, or you suspect a mother with kits is present, professional help is worth the cost. A licensed operator will have the right equipment, knowledge of local regulations, and the ability to handle the animal safely if it sprays during removal.
