Quick Answer
The most common animals digging holes in yards are armadillos, skunks, raccoons, and moles. Armadillos leave conical 1-3 inch deep holes in a wandering line. Skunks make similar but fewer holes near structures. Raccoons peel back sod. Moles create raised tunnels with volcano-shaped mounds.
Quick Answer
In North Carolina, the most common yard diggers are armadillos (newly arrived), striped skunks, raccoons, moles, voles, and groundhogs. Armadillos leave shallow conical holes in a wandering line. Skunks dig small conical holes near structures. Groundhogs create large burrow entrances with dirt mounds. Moles create raised surface tunnels. Voles leave small holes with surface runways.
Identifying Yard-Digging Wildlife in North Carolina
North Carolina's diverse geography — from the Atlantic coastal plain in the east to the Piedmont in the center and the Appalachian Mountains in the west — supports an exceptionally wide range of yard-digging wildlife. Whether you live in Charlotte, Raleigh, Greensboro, Durham, Winston-Salem, or Asheville, chances are you have encountered holes in your lawn, raised tunnels in your grass, or burrow entrances near your home's foundation.
Correctly identifying the animal responsible is critical because each species requires a different management approach. Some, like the eastern mole, are merely nuisances. Others, like the nine-banded armadillo (a recent arrival in North Carolina), can cause significant structural damage overnight. Some, like the groundhog, are seasonal diggers that can undermine foundations and outbuildings.
This guide synthesizes data from the North Carolina Wildlife Resources Commission (NCWRC), North Carolina State University Extension, and the USDA APHIS Wildlife Services program.
North Carolina Yard-Digging Animal Identification Table
| Animal | Hole Size & Shape | Depth | Damage Pattern | NC Range |
|---|---|---|---|---|
| Nine-banded Armadillo | Conical, 3-5 inch diameter | 1-3 inches (shallow) | Dozens of holes in a wandering line | Southern and central NC; expanding north |
| Striped Skunk | Conical, 3-4 inch diameter | 2-4 inches | Fewer holes, scattered; near structures | Statewide |
| Raccoon | Irregular torn patches | Shallow (sod rolled back) | Sod peeled back in sections | Statewide |
| Eastern Mole | Raised surface tunnels; no mounds | Just below surface | Ridged trails through grass | Statewide; most common in Piedmont |
| Pine Vole | 1-1.5 inch holes, no mound | Surface to 3 inches | Surface runways under mulch; girdled plant roots | Statewide |
| Eastern Chipmunk | 2-3 inch clean hole | Several feet deep | Burrow under stones, walls, or foundations | Statewide; most common in mountains and Piedmont |
| Groundhog (Woodchuck) | 6-8 inch burrow entrance | Several feet deep | Large mound of dirt at entrance; nearby vegetation eaten | Statewide; most common in mountains and Piedmont |
| Gray Fox | 4-6 inch burrow entrance (sometimes) | 3-4 feet deep | Den under outbuildings, decks, or hollow trees | Statewide; rarely digs in lawns |
Armadillos in North Carolina: A Recent Arrival
The nine-banded armadillo (Dasypus novemcinctus) is a relatively new arrival in North Carolina. According to the North Carolina Wildlife Resources Commission, armadillos were first documented in the state in the early 2000s, having expanded northward from Georgia and South Carolina. As of 2026, armadillos are established in the southern Piedmont and Sandhills regions, with confirmed sightings as far north as the Triangle (Raleigh-Durham) and Charlotte metro areas.
Armadillos dig for grubs, earthworms, and other soil invertebrates, creating dozens of shallow conical holes in a single night of foraging. They prefer moist, shaded areas with loose soil and are most active from dusk to dawn. In North Carolina, armadillo damage peaks from May through September, and NCWRC is actively tracking their range expansion. Homeowners who observe armadillos in counties outside their known range are encouraged to report sightings to the NCWRC Wildlife Diversity program.
Identifying Armadillo Damage vs Other Diggers
| Feature | Armadillo | Skunk | Mole |
|---|---|---|---|
| Hole shape | Conical, 3-5 inches | Conical, 3-4 inches | No visible hole (raised tunnel) |
| Hole depth | 1-3 inches | 2-4 inches | N/A (subsurface) |
| Number of holes | Dozens in one night | Fewer (5-10) | No holes (tunnels) |
| Mound present? | No | No | No (but may push up ridges) |
| Footprints | 4-toe front, 5-toe back | 5 toes, claw marks | Rarely visible |
| Odor | None | Strong musk near den | None |
Groundhogs: North Carolina's Large Burrowers
The groundhog (Marmota monax), also known as the woodchuck, is one of North Carolina's most destructive yard-digging animals, particularly in the Piedmont and mountain regions. Groundhogs dig large burrow systems with entrances 6-8 inches in diameter, often accompanied by a large mound of excavated dirt at the main entrance. A single groundhog burrow can extend 8-50 feet in length and have multiple entrances.
Groundhog burrows are typically found near structures (under sheds, decks, foundations, or along fence lines) where the surrounding vegetation provides cover. The danger of groundhog burrows is structural — burrows under foundations, driveways, or outbuildings can cause settling and collapse. Groundhogs also damage gardens by eating vegetables, fruits, and ornamental plants.
Groundhog vs Armadillo Damage Comparison
| Feature | Groundhog | Armadillo |
|---|---|---|
| Burrow entrance | 6-8 inches, large mound of dirt | No burrow (just foraging holes) |
| Hole shape | Round, clean entrance | Conical foraging holes |
| Hole depth | Several feet deep (burrow system) | 1-3 inches (shallow) |
| Vegetation damage | Eats nearby plants, garden vegetables | No plant damage (eats insects) |
| Activity time | Daytime (diurnal) | Nighttime (nocturnal) |
Skunks: North Carolina's Nighttime Diggers
Striped skunks (Mephitis mephitis) are common throughout North Carolina and are a frequent cause of lawn digging in both suburban and rural areas. Skunks dig for grubs, insects, and earthworms, creating small conical holes similar to armadillo holes but typically shallower and more scattered. The key differentiator is that skunk damage is usually concentrated near structures — under decks, near foundations, or along fence lines where they feel protected.
Another telltale sign of skunks is the presence of small, 1-inch diameter divots in the lawn where they have probed for insects with their noses. These "skunk divots" are often found in rows and look like someone pressed a finger into the soil repeatedly. NC State Extension reports that skunk damage in North Carolina typically peaks in spring (March-May) when grubs are near the surface following winter dormancy.
Moles and Voles: Subsurface Damage
Eastern Moles
Eastern moles (Scalopus aquaticus) create raised surface tunnels that look like ridges running through North Carolina lawns. They do not create visible holes or mounds (that is the pocket gopher, which is NOT found in North Carolina). Moles eat earthworms and soil insects, not plant roots. Their tunnels can kill grass by separating roots from soil, creating brown streaks in the lawn. Mole activity in NC is most pronounced in the Piedmont region, where clay-loam soils are easy to excavate.
Pine Voles
Pine voles (Microtus pinetorum) create surface runways under mulch or leaf litter and 1-1.5 inch holes with no surrounding mound. Unlike moles, voles DO eat plant roots and can girdle the base of shrubs and small trees, killing them. If your plants are dying for no apparent reason and you see small holes nearby, suspect voles. Pine vole damage is particularly common in the North Carolina mountains, where thick leaf litter provides ideal runway habitat.
Mole vs Vole Comparison
| Feature | Eastern Mole | Pine Vole |
|---|---|---|
| Diet | Earthworms, soil insects | Plant roots, bulbs, bark |
| Surface damage | Raised tunnels/ridges | Surface runways under mulch |
| Holes | None visible | 1-1.5 inch, no mound |
| Plant damage | Brown grass streaks | Girdled roots, dying shrubs |
| Body size | 4-7 inches, paddle-like feet | 3-5 inches, mouse-like |
Seasonal Digging Patterns in North Carolina
| Season | Most Active Diggers | Why |
|---|---|---|
| Spring (Mar-May) | Skunks, armadillos, chipmunks, groundhogs | Grub emergence; breeding season; groundhogs emerge from hibernation |
| Summer (Jun-Aug) | Armadillos, moles, voles | Peak insect activity; soil moisture high; armadillo young foraging |
| Fall (Sep-Nov) | Skunks, raccoons, groundhogs | Acorn/nut season; animals building fat reserves; groundhogs deepen burrows |
| Winter (Dec-Feb) | Moles, voles (reduced activity) | Groundhogs hibernate; armadillos less active in cold; moles stay below frost line |
How to Stop Animals from Digging in Your North Carolina Yard
1. Reduce Grub Populations
Most digging animals (armadillos, skunks, raccoons, moles) are attracted to white grub populations in lawns. Apply beneficial nematodes (Heterorhabditis bacteriophora) or milky spore (Paenibacillus popilliae) in late spring or early summer when soil temperatures are above 60°F. According to NC State Extension, beneficial nematodes can reduce grub populations by 50-80% within 2-4 weeks, making lawns significantly less attractive to diggers.
2. Exclusion Fencing
- Armadillos: 24-inch fence buried 12-18 inches with L-shaped footer
- Skunks: 3-foot fence buried 6 inches; also seal openings under decks and sheds
- Groundhogs: 3-foot fence buried 12 inches with a top rail; they can climb
- Voles: Install 1/4-inch hardware cloth cylinders around vulnerable tree and shrub roots, buried 3-4 inches deep
3. Live Trapping
In North Carolina, armadillos, skunks, and groundhogs can be live-trapped on private property. However, NCWRC regulations prohibit relocating trapped wildlife off your property without a permit — most nuisance wildlife must be euthanized on-site or released on the same property. Always check current NCWRC regulations before trapping, and contact a licensed Wildlife Damage Control Agent (WDCA) if you are uncertain about legal requirements.
4. Habitat Modification
- Remove brush piles, fallen logs, and debris that provide cover
- Keep grass mowed short to reduce insect habitat
- Reduce irrigation to lower grub and earthworm populations
- Use hardware cloth (1/4 inch mesh) to protect bulb plantings from voles
- Fence gardens with 3-foot chicken wire with a 12-inch buried footer to exclude groundhogs
North Carolina-Specific Regulations
- Armadillos: Classified as non-native, non-game wildlife in North Carolina. Can be trapped and removed on private property without a permit. NCWRC requests sightings be reported to track range expansion.
- Skunks/Raccoons: Can be trapped on private property. Rabies-vector species restrictions apply — relocation is prohibited. Must be handled by a licensed Wildlife Damage Control Agent for off-property issues.
- Groundhogs: Classified as non-game wildlife in North Carolina. Can be trapped and removed on private property without a permit. May be hunted during established seasons with appropriate licenses.
- Moles/Voles: No protection. Can be trapped, gassed, or controlled on private property.
FAQ: North Carolina Yard Digging
Are armadillos in North Carolina yet?
Yes. As of 2026, nine-banded armadillos are established in the southern Piedmont and Sandhills regions of North Carolina, with confirmed sightings in the Charlotte metro area and as far north as the Triangle (Raleigh-Durham). According to NCWRC, armadillos continue to expand their range northward at approximately 4-6 miles per year. They have not yet become established in the mountain counties or the northern coastal plain, but sightings should be reported to NCWRC for tracking.

What is digging small conical holes in my North Carolina lawn?
In North Carolina, small conical holes (3-4 inches wide, 2-4 inches deep) are most likely from striped skunks, particularly if they are scattered and concentrated near structures. Larger conical holes (3-5 inches, 1-3 inches deep) in a wandering line are from armadillos (southern/central NC only). Very small holes (under 1 inch) could be from voles, shrews, or solitary bees.
How do I know if I have a groundhog?
Groundhog burrows are unmistakable: a 6-8 inch diameter round hole with a large mound of excavated dirt at the entrance. Burrows are typically located near structures (under sheds, decks, or along foundations) and may have multiple entrances. Groundhogs are diurnal (active during the day), so you may see them foraging on garden vegetables in early morning or late afternoon.
How do I know if I have moles or voles?
If you see raised ridges/tunnels in your grass with no visible holes, you have moles. If you see small holes (1-1.5 inches) with surface runways under mulch, and your shrubs are dying with girdled roots, you have voles. Moles eat insects; voles eat plants. Note: pocket gophers (which make volcano-shaped mounds) are NOT found in North Carolina — if you see mounds, suspect moles pushing up soil in clumps, not true gopher mounds.
Do North Carolina skunks carry rabies?
Yes. Skunks are one of the primary rabies reservoir species in North Carolina, along with raccoons, bats, and foxes. According to the North Carolina Department of Health and Human Services, the eastern raccoon rabies variant is endemic statewide, and skunks frequently contract raccoon-variant rabies. Never approach a skunk, especially one active during daylight hours, and ensure your pets are current on rabies vaccinations.
When is digging worst in North Carolina?
Late spring (April-May) is typically the worst season for yard digging in North Carolina. Grubs are near the surface following winter dormancy, skunks and raccoons are actively foraging after breeding season, and groundhogs have emerged from hibernation. A secondary peak occurs in late summer (August-September) when armadillo young begin foraging independently.
