Skunk Holes in Texas Lawn: How to Tell & Stop the Nightly Digging

The first sign is usually subtle. You notice three or four small holes in one corner of the lawn — not scattered everywhere, just in that one section near the fence line where the grass always seemed a little greener. The next morning, there are a few more. By the third morning, you step outside at dawn and catch a faint, musky, almost burnt-coffee smell hanging in the air. You have a skunk.

Skunk damage in Texas lawns is frequently misdiagnosed as armadillo damage. Homeowners spend money on armadillo traps, armadillo repellent, and armadillo exclusion — and the skunk keeps digging. This guide will teach you how to tell them apart definitively, and what to do about it.

Skunk vs Armadillo Damage: The Hole Comparison Table

Why Skunks Dig (It's Not What You Think)

Skunks are not vandals. They are efficient, methodical hunters. A skunk's diet is 70-80% insects and insect larvae, with the remainder being small rodents, eggs, berries, and carrion. In a Texas lawn, the primary target is white grubs — the C-shaped larvae of June beetles (Phyllophaga) and other scarab beetles that live in the top 2-4 inches of soil, chewing on grass roots. A single square foot of healthy Texas lawn can contain 6-10 grubs.

The skunk's digging technique is different from the armadillo's, and understanding this difference is how you tell them apart. A skunk walks slowly across the lawn, pausing every few inches to sniff. When it detects a grub moving underground (skunks can smell grubs through 2-3 inches of soil), it digs a single precise hole, extracts the grub with its front claws, and moves on. The result is a concentrated patch of neat, cone-shaped holes. An armadillo, by contrast, roots aggressively with its nose — pushing, shoveling, and tearing at the soil — leaving behind scattered, messier holes.

The Smell Test: When to Trust Your Nose

Skunks do not constantly smell. The signature musk is a defensive spray used only when the animal feels threatened. However, skunks do have a general body odor — a faint, musky, slightly sweet smell that is most noticeable in the early morning (before the sun burns it off) near the digging site, under decks, or near crawl space entrances where a skunk may be denning. If you kneel near the holes at 6am and detect a faint musky odor, that is as close to a definitive ID as you'll get without a trail camera. Armadillos have no detectable body odor at all.

5 Other Animals That Could Be Mistaken for Skunk Damage

Animal	How to Rule It Out
Squirrel	Squirrels dig shallow, irregular holes to bury or retrieve nuts — not cone-shaped, not grub-focused. Holes are scattered, not clustered.
Raccoon	Raccoons tear up sod in large patches, flipping it over like someone rolled up a carpet. They don't dig neat holes. Tracks show five long, finger-like toes (skunk tracks show five toes with visible claw marks, shorter and rounder).
Opossum	Opossums rarely dig. They may make shallow, indistinct nose-poke holes in mulch or leaf litter. Not cone-shaped.
Fox or Coyote	Much larger holes (6-12+ inches wide) and deeper. Usually hunting for rodents like gophers or voles, not grubs.
Wild Hog	Hog rooting is large-scale destruction — entire sections of turf torn up and flipped. Cannot be confused with skunk holes.

How to Stop Skunk Digging: What Actually Works

The permanent solution is the same as it is for armadillos: eliminate the food source. Skunks are digging because your lawn has a healthy grub population. Kill the grubs, and the skunk will move on within days because there is nothing to eat.

Option A: Beneficial Nematodes (Best for Most Homeowners)

Heterorhabditis bacteriophora nematodes are microscopic parasitic worms that seek out and kill white grubs. Apply with a hose-end sprayer when soil temperature is above 60°F (March through October in most of Texas). They are pet-safe, child-safe, and do not harm earthworms. Results in 2-4 weeks. This is the most cost-effective, lowest-risk option and is the #1 recommendation from Texas A&M AgriLife for residential grub control.

Option B: Milky Spore (Only for Japanese Beetle Grubs)

Paenibacillus popilliae is effective only against Japanese beetle grubs. In Texas, the predominant grub species is the June beetle (Phyllophaga), which milky spore does not control. Unless you have confirmed Japanese beetles are your specific grub species, skip milky spore. It will not work.

Option C: Chemical Grub Control (Fast but Requires Care)

Chlorantraniliprole (Acelepryn) is the preferred chemical option. It is selective for grubs and has low non-target toxicity. Imidacloprid (Merit) also works but is a neonicotinoid and may affect pollinators. Always follow label instructions. In Texas, commercial application may require a pesticide applicator license.

What Does NOT Work (Don't Waste Your Money)

• Mothballs or ammonia-soaked rags: Mothballs are illegal to use outdoors under FIFRA. Ammonia evaporates in hours. Neither deters a skunk from a reliable food source. This is the most common bad advice on neighborhood Facebook groups.
• Cayenne pepper, garlic, or predator urine: Washes away in the first rain. Skunks can tolerate mild irritants when food is nearby.
• Bright lights or loud noises: Skunks are nocturnal but not particularly light-sensitive. A porch light will not deter a hungry skunk.
• Trapping without grub treatment: You remove one skunk. The grubs remain. A new skunk moves in within days. Trapping alone is a subscription, not a solution.

What If the Skunk Is Denning Under Your Deck or Shed?

If you have skunk holes AND smell a stronger musky odor near a structure, the skunk may be living on your property. Skunks do not dig their own burrows — they take over abandoned armadillo burrows, groundhog dens, or crawl spaces. Signs of a skunk den:

• Stronger, more persistent musky odor near one specific structure
• Digging concentrated in a radius around a deck, shed, or crawl space entrance
• Skunk scat near the den entrance (contains visible insect parts and berry seeds)
• 5-toed tracks with visible claw marks in soft soil near the structure

If you have a denning skunk, do not attempt to evict it yourself. A cornered skunk will spray, and skunk musk can cause temporary blindness if it hits the eyes. Call a licensed wildlife removal professional. They will use a one-way exclusion door — the skunk exits to feed at night and cannot re-enter. Once the skunk is out, the professional seals the entry point with hardware cloth buried 12 inches deep in an L-shape to prevent re-entry.
