If you’ve woken up to find chunks of your lawn torn apart overnight, raccoons or skunks are the most likely culprits. Both animals dig up turf to hunt for grubs, earthworms, and other insects living just below the surface, and both do their work after dark. The damage often appears suddenly in late summer or fall and can cover large patches of yard in a single night.
The good news: the digging pattern itself tells you which animal is responsible, and the real fix isn’t trapping or repelling the animals. It’s eliminating the grubs that drew them to your yard in the first place.
Raccoon Damage vs. Skunk Damage
Raccoons and skunks both leave behind torn-up sod, but they dig differently. Raccoons have dexterous front paws that work like hands. They grab the edge of a section of turf and peel it back in neat flaps or rolls, almost as if someone lifted the sod with the intent of transplanting it elsewhere. You’ll see large, cleanly folded-back pieces of grass with the soil exposed underneath.
Skunks are less tidy. They push their noses into the ground and dig shallow, cone-shaped holes scattered across the lawn, typically 3 to 4 inches wide and a couple of inches deep. Instead of peeled-back sod, you get a pockmarked lawn that looks like someone jabbed a garden trowel into it dozens of times. If you see both rolled sod and scattered divots, you may have both visitors.
Other clues help confirm which animal you’re dealing with. Raccoon droppings are cigar-shaped, 2 to 3 inches long, and about three-quarters of an inch wide. Skunk droppings are smaller, 1 to 2 inches long and half an inch wide, and often contain visible insect parts. A lingering musky smell near the damage points toward skunks, even if they didn’t spray.
Ruling Out Other Animals
Not every hole in a yard comes from raccoons or skunks. Moles create raised ridges and round mounds of soil pushed up from below, not torn-up sod. Their tunnels run just below the surface and the dirt mounds often appear in a line. Ground squirrels dig clean, open burrow holes about 4 inches in diameter with little or no dirt mound around the entrance, and their burrow systems can stretch 5 to 30 feet underground. Tree squirrels dig small, shallow holes where they bury nuts and acorns, usually just a couple of inches across.
The key distinction is that raccoon and skunk damage involves pulling up or peeling back existing turf to get at insects underneath. Moles, squirrels, and voles create tunnels or discrete holes for nesting and food storage. If your sod is ripped up in patches, you’re almost certainly dealing with a grub-hunting raccoon or skunk.
Why They’re Digging: The Grub Problem
Raccoons and skunks are omnivores, but beetle grubs are among their favorite foods. White grubs, the larvae of Japanese beetles and other scarab beetles, live in the top few inches of soil from late summer through fall, feeding on grass roots. A lawn with a heavy grub population is essentially an all-you-can-eat buffet. Earthworms and other soil-dwelling insects add to the attraction.
The timing isn’t random. Grubs hatch and grow through summer, reaching their largest and most detectable size by early fall. That’s when raccoons and skunks can smell them through the turf and the digging intensifies. If your damage started in August or September and got worse through October, the seasonal grub cycle is almost certainly driving it.
Eliminating Grubs to Stop the Digging
Repelling the animals treats the symptom. Removing their food source solves the problem. If grubs are confirmed in your lawn (pull back a square foot of sod and count them; more than about 10 per square foot is a significant infestation), treating the grubs will make your yard far less interesting to wildlife.
For a biological approach, milky spore is a naturally occurring bacterium that targets Japanese beetle grubs specifically. Once a grub ingests a single spore, that spore multiplies into roughly 3 billion new spores inside the grub, killing it within about a week. As the grub decomposes, those billions of spores release back into the soil to infect the next generation. The tradeoff is patience: milky spore granules need to be applied in spring, summer, and fall for two consecutive years (six total applications) to build up adequate spore levels in the soil. After that, control can last up to 10 years without reapplication.
Beneficial nematodes, microscopic worms that hunt grubs underground, can complement milky spore. They’re unharmed by the bacteria and actually help spread it as they move through the soil pursuing larvae. Apply milky spore dry, then water in the nematodes for combined coverage. Nematodes work against a broader range of grub species than milky spore alone, which only targets Japanese beetle larvae.
Chemical grub treatments are also available at garden centers and work faster, but they affect a wider range of soil organisms. Whichever route you choose, treating in late summer or early fall targets grubs when they’re young and close to the surface.
Deterrents While You Wait
Grub treatments take time to reduce populations, so you may need short-term deterrents to protect your lawn in the meantime. Motion-activated sprinklers are one of the more effective non-lethal options. These devices detect movement with infrared sensors and blast a sudden jet of water, startling nocturnal visitors enough to send them elsewhere. Solar-powered models that combine water jets with flashing lights can cover a wider area.
Temporary physical barriers also work for small areas. Laying chicken wire or garden netting flat over the most damaged sections of lawn makes it difficult for raccoons and skunks to peel back the turf. Stake the edges down so animals can’t simply push underneath. This is impractical for an entire yard but can protect the worst spots while grub treatments take effect.
Repairing the Damage
Raccoon and skunk damage looks dramatic but often recovers well because the grass roots may still be intact. If the sod has been peeled back but hasn’t dried out, simply press or roll it back into place and water it thoroughly. Step on each piece firmly to ensure good root-to-soil contact. Turf that’s been flipped for less than 24 hours usually re-establishes if you get it back down and keep it moist.
For sections where the sod has dried out or been torn into small pieces, rake the area smooth, add a thin layer of topsoil if needed, and reseed. Early fall is actually ideal timing for reseeding cool-season grasses, so the damage and the repair window often overlap. Keep reseeded areas consistently moist for two to three weeks until germination is well underway.
A Safety Note on Raccoon Droppings
Raccoon feces can carry a roundworm called Baylisascaris that poses a serious health risk, particularly to young children. The eggs become infectious after sitting in the environment for 2 to 4 weeks and can survive in soil for years. Raccoons tend to use the same spots repeatedly (called latrines), often at the base of trees, on flat surfaces like stumps or decks, or in other sheltered areas.
If you find a raccoon latrine in your yard, don’t sweep or rake it dry, as that can send microscopic eggs airborne. Mist the area with water first, then wear disposable gloves and rubber boots to collect the material. Double-bag everything and place it in the trash, or bury or burn it. Contaminated hard surfaces like decks or patios can be treated with boiling water to kill remaining eggs. Symptoms of Baylisascaris infection, which include nausea, fatigue, loss of coordination, and in severe cases vision loss, typically appear 1 to 4 weeks after exposure. If a child may have come into contact with raccoon feces, contact a healthcare provider promptly, as early treatment can reduce the severity of the disease.
