Skunks don’t build visible nests above ground like birds or squirrels. Instead, they den in underground burrows or sheltered spaces beneath structures, lining the interior with dried grasses and weed stems. If you’ve spotted a suspicious hole in your yard or heard rustling under your porch, you’re likely dealing with a skunk den rather than a traditional nest. The entrance is typically about four to five inches in diameter, roughly the size of a grapefruit, with a smooth mound of dirt around the opening.
What a Skunk Den Looks Like
A skunk den entrance appears as a clean, rounded hole with loose soil pushed outward in a small mound. The burrow itself can extend 6 to 20 feet underground and may house more than one skunk. Inside, a mother skunk will gather dried grasses and weed stems to form a nest where she gives birth and raises her kits.
Skunks are opportunistic about where they set up. They frequently move into abandoned burrows originally dug by ground squirrels, foxes, or coyotes, widening the tunnels to fit. In residential areas, they skip the digging altogether and settle under porches, decks, sheds, trailers, and crawl spaces. These ready-made shelters offer protection from weather and predators with far less effort than excavating a new burrow.
Signs a Skunk Den Is Active
The entrance hole alone doesn’t confirm a skunk is home. Look for these additional clues:
- Tracks near the entrance: Skunk prints show five toes on each foot with visible claw marks.
- A faint musky odor: Even when skunks aren’t spraying, their dens carry a lingering scent.
- Small cone-shaped holes in the lawn: Skunks dig shallow pits, one to three inches across, while foraging for grubs. Multiple holes scattered across your yard suggest a skunk is feeding nearby.
- Rolled-back sod: Skunks will peel up sections of lawn to reach insects underneath, leaving noticeable damage.
- Raided garbage cans: Overturned or rummaged-through trash is a common sign of nighttime skunk activity.
If you’re seeing several of these signs concentrated near a hole or a gap under a structure, you very likely have an active den.
When Skunks Are Most Likely Nesting
Skunk breeding season runs from late February through March. Females give birth in early May, with litters averaging four to six kits. The babies are born blind and completely helpless, so they stay hidden in the nest for several weeks until they can see and are strong enough to follow their mother outside.
Kits nurse for about two months before weaning. By three months old, they begin dispersing to find their own territories. This means a den discovered in May, June, or July almost certainly contains babies. Some females produce two litters per year, though one is far more common.
This timeline matters if you’re planning to seal off access to a den. Blocking an entrance in late spring or summer can trap flightless kits inside, where they’ll die. The safest window for exclusion work is late fall through early winter, after young have dispersed and before the next breeding cycle begins.
How to Encourage Skunks to Leave
Skunks prefer dark, quiet, undisturbed spaces. Making a den site uncomfortable is often enough to convince them to relocate. Place a bright light near the entrance and leave it on overnight. A portable radio tuned to a talk station adds noise disturbance. Some people soak rags in ammonia and place them near (not inside) the entrance, since the strong smell is unpleasant to skunks.
Give these deterrents three to five nights to work. Skunks are creatures of habit, but they’ll abandon a den that no longer feels safe. To confirm the den is empty before sealing it, loosely stuff the entrance with newspaper or leaves. If the material stays undisturbed for three consecutive nights, the skunk has moved on.
Once the den is confirmed empty, close off the space permanently. For burrows, fill the hole with packed soil and gravel. For gaps under porches, decks, and sheds, attach galvanized hardware cloth or welded wire mesh along the base, burying it at least 12 inches deep to prevent skunks from digging underneath. This L-shaped footer is the most reliable long-term barrier.
Health Risks Around Skunk Dens
Skunks are one of the most common carriers of rabies in the United States. The virus spreads through bites, and any skunk bite, no matter how minor, requires immediate medical attention. A skunk that wanders around during daylight, appears tame or listless, or shows no fear of people and pets is exhibiting classic symptoms of rabies and should be avoided entirely.
Beyond rabies, skunks can carry leptospirosis, canine distemper, canine hepatitis, and several other diseases that pose risks to both people and pets. Their dens can also harbor fleas, ticks, and mites that linger in the soil and bedding material even after the skunk leaves. If a skunk has been denning under your home, it’s worth treating the area for parasites after the animal has gone.
Never attempt to handle a skunk directly. Even a healthy skunk will spray when cornered, and the oily musk is notoriously difficult to remove from skin, clothing, and pets. If deterrent methods aren’t working or you suspect babies are present, a licensed wildlife control operator can assess the situation and remove the animals safely.
Preventing Skunks From Returning
Skunks are drawn to easy food and sheltered denning spots. Eliminating both makes your property far less attractive. Secure garbage cans with tight-fitting lids or bungee cords. Pick up fallen fruit from trees. Avoid leaving pet food outside overnight. Treating your lawn for grubs removes the primary food source that draws skunks to dig in the first place.
Seal gaps under every structure on your property before denning season starts. Skunks need surprisingly little clearance to squeeze through, so inspect for openings wider than four inches. Stack firewood tightly and store it off the ground. Keep window wells covered. These simple steps make it far less likely that a skunk will choose your yard for its next den.
