What's Digging Holes in My Yard? Identifying the Offender

Posted on 2026-01-18 18:20:32

Likely candidates consist of squirrels, moles, voles, skunks, raccoons, armadillos, groundhogs, chipmunks, pet dogs, and bugs like cicada killers. The size, shape, location, and soil disruption around the holes tell you a lot, as do tracks, droppings, time of day the activity takes place, and what's missing out on from your yard. With a little observation, you can usually narrow it to a couple of species, then pick targeted fixes that really work.

I've walked numerous lawns with homeowners looking at a polka-dotted lawn and a sinking sensation in the gut. The majority of holes are not emergencies, but they can indicate genuine damage to turf, gardens, and watering. The technique is to identify before you deal with. A generic approach wastes money and often makes the issue worse. Below, I'll break down what I search for, case by case, and where I fix a limit and call a licensed exterminator or wildlife control operator.

Start with the hole, not the animal

You most likely will not catch the trespasser in the act. The ground is your witness, and it speaks. Get a tape measure. Picture the hole next to a coin or a glove for scale. Keep in mind the time you initially observed activity and whether it's repeating after rain or mowing.

Hole diameter matters. So does whether there's a mound, a fan of loose soil, claw marks, or smooth edges. Fresh soil has a richer color and holds shape; older holes collapse and gray out. Smell the soil if you can endure it. Skunk digs typically bring a faint musk. Raccoon latrines are apparent once you have actually seen one, but let's hope you have not.

Quick size guide, with personality

Small holes the size of a cent to a quarter, shallow and scattered, indicate insects or little rodents. Golf ball size to tangerine size recommends chipmunks, squirrels, or wasps. Baseball to softball size burrows with defined entryways, sometimes with a stack of excavated soil, recommend mammals that live underground or raid lawns during the night. Anything larger than a grapefruit, with a clear tunnel and fresh spoil, brings groundhogs or armadillos into play.

Squirrels: neat divots with a habit

Squirrels cache and recover food by making small, shallow divots 2 to 3 inches broad. These holes seldom go deeper than 2 inches, and they often appear near trees or along fence lines where squirrels take a trip. In fall you'll see a burst of activity as they bury acorns and pecans. In spring they dig some of them up. Soil is typically discarded gently, not piled.

What helps: thinning heavy nut drop, raking regularly, eliminating fallen fruit, and utilizing hardware cloth to secure beds. Repellents can lower activity short term, but they rinse. Do not waste money on sonic stakes for squirrel holes. If the lawn is pocked however not collapsing, you're taking a look at nuisance, not structural damage.

Chipmunks: little burrowers with hidden doorways

Chipmunk burrow entryways run around one and a half to 2 inches large, cool and round, with no excavated mound at the entrance. That absence of a soil stack is a trademark. They carry soil away in cheek pouches and discard it discreetly. You'll find entrances at piece edges, actions, maintaining walls, and rock borders. If the hole lives under an air conditioner pad or concrete stoop, chipmunks are among the first suspects.

Typical signs include plant roots munched off from listed below and hollow courses under mulch where they commute. I have actually seen stoops settle when chipmunk burrows honeycomb the soil. Live-trapping with sunflower seed works, however you require to close gain access to afterward with quarter-inch hardware cloth and repaired mortar joints. If they're undermining structures, seek advice from wildlife control.

Moles: engineers of the subsurface

Moles do not eat your plants; they eat grubs and earthworms. Their signature is the raised runway. You'll feel spongy ridges underfoot and see volcano-like mounds if they're excavating deep tunnels. The holes themselves are not normally open; you're discovering collapsed parts where the roofing system gave way under a lawn mower wheel or after rain. Yard appears like somebody laid a garden hose pipe simply under the sod.

Key information: active mole runs feel firm and springy if you press with a palm, and they get rebuilt within a day after you tamp them down. Non-active runs flatten and stay flat. Control choices include trapping along active runs, decreasing grub populations if your grass has recorded grub pressure, and preventing overwatering, which draws earthworms upward and keeps soil moist, conditions moles take pleasure in. Grub control alone does not guarantee mole elimination since worms are a primary food. Professional mole trapping works when positioned on straight, regularly used runs.

Voles: plant assassins with pinholes

Voles, typically called meadow mice, leave silver-dollar sized openings and, more informing, quarter-inch wide runways pressed through grass and mulch. In winter, they tunnel under snow and after that reveal a damage map when the thaw comes. You'll find girdled shrubs with bark chewed at the base and bulbs hollowed like apples. Unlike moles, voles do consume roots, bulbs, and bark.

What helps: snap-traps in peanut butter bait stations positioned perpendicular to runways, habitat reduction by pulling mulch back from trunks, and tight hardware cloth collars around young trees. Felines make a damage. Toxin baits are available but come with non-target risks. If voles are heavy and neighbors are also affected, a collaborated effort works better than a solo campaign.

Skunks: neat cones at night

Skunks penetrate yards carefully but constantly, especially when grubs are plentiful. The holes are cone-shaped, about one to 3 inches wide, and shallow, like somebody poked the lawn with a finger. Nighttime activity, grub-chasing, and a faint musk give them away. In heavy invasions, a yard can look like it was peppered with a golf tee.

Skunks will also den under decks and sheds, where you may see a larger opening, 4 to 6 inches broad, with soft soil at the limit and a visible odor. If you suspect a den and it's spring, be cautious; there may be packages. Exemption with one-way doors is a timing video game and is finest delegated pros. Long-term, fix the food source. If a soil sample or turf tug test reveals grubs at destructive levels, treat the lawn. If you do not have grubs, skunks normally lose interest.

Raccoons: yard roll-up artists

Raccoons are strong, curious, and nocturnal. Where skunks peck, raccoons pry. They roll back grass like a carpet to consume grubs and worms beneath, leaving flaps of sod or square areas nicely turned. If your grass lifts quickly in mats, raccoons or armadillos are prime suspects depending on region. Tracks in soft soil program hand-like prints with noticeable fingers and nails.

Preventive steps consist of securing trash, removing pet food, and bright motion lights. To discourage yard turning, water less in the evening, which lowers earthworms near the surface. Where damage is severe, a wildlife pro can set compliance traps, but you require to integrate capture with access control and food decrease or you create a revolving door.

Armadillos: diggers with a travel route

In the southern states, armadillos leave quarter to baseball sized conical holes, 2 to five inches deep, while foraging for grubs and insects. They operate at night and follow regular paths. Their burrows are bigger, often 8 inches across, with crescent-shaped spoil stacks and a distinct earthy odor. Unlike raccoons, they won't roll turf, they puncture it. If you have a slope with soft soil and a lot of beetle activity, armadillos discover it fast.

They are infamously trap-shy unless you funnel them with boards along their normal routes. Fencing to omit them should be buried or turned outside at the base. Control of white grubs reduces interest however doesn't remove it entirely. Examine local regulations before any control; some locations restrict methods.

Groundhogs: big holes, huge appetite

A groundhog burrow looks like a 8 to twelve inch round hole with a large mound of excavated soil nearby, often with a secondary escape hole without a mound. You'll find gnawed greenery near to the entryway and well-worn paths. They love clover, beans, lettuce, and flowers. Under decks, sheds, and embankments are prime den areas. I as soon as checked a groundhog den with a smoke bomb the owner had tried. The smoke poured out two additional holes twenty feet away. That's common, which is why half steps fail.

Groundhogs are strong diggers and can weaken slabs. If family pets or kids utilize the lawn, don't leave an active burrow open. Lethal control and moving have legal constraints and disease risk. This is where a licensed wildlife operator earns their charge: setting body-grip traps at the den in accordance with state law, then installing a buried exemption skirt to prevent re-entry.

Rabbits: small holes are red herrings

Rabbits do not dig big burrows in the majority of yards. They utilize shallow scrapes in mulch or turf, called types, and often nest in anxieties lined with fur. What looks like a hole might be a nest cavity covered with thatch. If you find infant bunnies, cover the nest lightly and keep pets away; the mom returns briefly at dawn and sunset. If you see a two to three inch entrance under a low shrub, it might be a chipmunk, not a rabbit.

Wasps and bees: search for traffic, not dirt

Cicada killer wasps produce excellent quarter-sized holes with a fan of loose soil and a pebble or two at the rim, usually in bare, sun-baked ground. They are big, challenging fliers, however singular and generally non-aggressive far from active burrows. Yellow coats, by contrast, use existing cavities and you won't see a cool pile or a specified tunnel the way mammals do. What you will see is traffic. If the hole hums with comings and goings throughout daytime, call a pest control service that handles stinging bugs. Do not pour fuel into holes, ever. It kills soil, risks groundwater, and does not reliably reach the nest.

Ants and termites: mounds and pellets

Ants bring soil up in crumbly mounds with numerous tiny openings. Fire ants build tall, soft mounds without a central crater. Termites do not expose holes, however you may see pencil-thin mud tubes up foundation walls or sand-like pellets from drywood termite kickout holes in structures, not lawns. If you notice uniform, peppery pellets around a wooden limit, gather a sample for identification. Yard ants are normally a problem; structural termites are not. When wood is included, bring in a certified pest control operator for an inspection and a targeted treatment plan.

Dogs and human factors

Sometimes the offender is a bored dog, a professional who left test holes, or a next-door neighbor's family pet that gos to during the night. Dog holes are normally wider, messier, and located near cool soil under shrubs or where something smells intriguing, such as a buried bone or drip line. Movement cameras fix these secrets quickly.

I have actually likewise had two backyards where irrigation leaks softened soil so badly that animal traffic seemed to take off. When the leakage was repaired and the ground dried, activity dropped. Soft ground welcomes digging because insects and worms are plentiful. Constantly inspect watering if the damage pattern follows a pipeline route.

Reading the context: season, weather, and region

In the Midwest, grub feeding peaks late summer into fall, which is when skunks and raccoons go to work. In northern environments, vole damage appears after snowmelt. In the Southeast and Gulf states, armadillos and fire ants make complex the picture. Wet springs bring earthworms to the surface area and moles follow. Drought focuses activity around irrigated lawns. If you understand what's in season, you can prepare for and prevent.

How to verify without guesswork

A trail electronic camera with night vision, set six to 10 inches above ground and intended across a presumed runway or hole, typically solves the puzzle in two nights. Fresh flour around the hole entryway records tracks without harming animals. A plank over a mole run with a cup inverted beneath can identify an active push. These low-tech techniques minimize the threat of dealing with the wrong species.

If you choose a tidy, very little method before committing to equipment, do a two-day test: tamp mole ridges at night, then look for new pushes at dawn; rake skunk pecks smooth at sunset, then try to find fresh cones in the early morning; fill chipmunk holes lightly with soil to see which resume within 24 hours, then enjoy those entryways from a window.

Prevention that really sticks

Most property owners ask for a single cure-all. There isn't one. The reputable path blends habitat modifications with targeted control. Cut at the proper height for your turf types so the canopy is dense and roots are strong. Avoid persistent overwatering; deep, occasional irrigation beats daily sprays. Minimize food for the animals you do not desire, which often means managing the animals they consume or removing simple calories like birdseed spills and fallen fruit.

Seal structural gaps bigger than half an inch with hardware cloth or mortar where useful. For decks and sheds, an exclusion skirt of galvanized hardware cloth buried six inches with a horizontal turn of twelve inches external stops most burrowers. When you garden, utilize bulb cages for tulips in vole nation and choose daffodils where possible because voles ignore them. If you should use repellents, turn active ingredients and don't expect wonders throughout heavy pressure.

When to bring in a pro

Certain scenarios push beyond DIY. Big denning animals under structures. Aggressive stinging pests with hidden nests. Repeating mole or armadillo damage over multiple seasons in spite of efforts. Circumstances near schools or public walkways where liability is genuine. A licensed exterminator or wildlife control operator brings species-specific traps, legal clearance, and experience putting them correctly. Inquire about their evaluation procedure, what they believe the target species is and why, and what they will do to avoid re-entry once the instant problem is fixed. Excellent pros discuss exemption and environment, not just removal.

Costs differ commonly by area and species. Mole trapping programs frequently run in multi-visit bundles. Groundhog elimination with exemption skirts can be a multi-day task. Constantly ask for a written strategy and guarantee terms. If somebody assures universal outcomes with a spray that "drives whatever away," be skeptical.

Safety notes you should not skip

Rodent baits can kill family pets and non-target wildlife through primary or secondary poisoning. If you use them, utilize locked bait stations, select formulas less most likely to trigger secondary kills where proper, and follow the label exactly. Fumigants for burrows are restricted-use in many states and can be lethal to unexpected animals, including pets. Never deploy a fumigant without appropriate licensing and training.

Gasoline, bleach, ammonia, and mothballs do not belong in the soil. They fail more than they prosper and contaminate your backyard. When you're handling skunks, remember the danger of rabies in numerous areas. Avoid cornering any animal, and keep pets leashed at sunset and dawn while you diagnose.

Matching common patterns to most likely culprits

Here's a concise field matching you can run through in your head.

Cone-shaped pecks throughout the lawn after a warm, damp night, plus a faint musk: skunks foraging for grubs. Sod rolled like carpet with square or rough edges, over night: raccoons, potentially armadillos in the South if there are leak holes too. Raised, spongy ridges that reappear after you press them down: moles, not voles. Two-inch round holes with no soil stack at piece edges or steps: chipmunks. Eight to twelve inch holes with a big spoil mound near sheds or embankments: groundhogs. Quarter-sized holes in difficult, warm soil with a loose fan of dirt, daytime wasp traffic: cicada killers.

Keep in mind that combined indications take place. A backyard can host moles developing tunnels and after that skunks exploiting them for a meal. If you see both runs and pecks, treat both parts of the equation or you'll chase your tail.

Repairing the lawn and beds after the culprit is gone

Once the activity stops, rake loose soil, topdress low areas with evaluated compost or topsoil, and reseed or plug as required. For rolled grass, water, press it back, and pin with naturally degradable stakes for a week. For vole runways, rake to rough up the thatch and overseed. For burrow entryways under structures, backfill only after you are specific the den is empty and you have set up exclusion. Filling an active den just moves the https://jsbin.com/xunirukona exit and might trap animals where you can't reach them.

If grubs belonged to the problem, choose a product that matches your timing. Preventive applications with active ingredients like chlorantraniliprole in late spring target newly hatched larvae. Curative products used in late summer take on existing grubs. Do not use both without a factor; test and verify pressure first.

A sensible expectation on timelines

Most lawn wildlife problems fix within 2 to 4 weeks when detected properly and attended to with concentrated actions. Moles may require a couple of strategic trap checks. Raccoons proceed as soon as the buffet closes. Groundhog elimination and exemption may take a week, sometimes 2 if there are several den holes. In contrast, vole population reductions can take a season because you're changing environment as well as numbers.

Give yourself a calendar marker. If you do not see improvement in seven to 10 days after an appropriate intervention, reassess. Either the species ID is incorrect, the food source remains, or gain access to wasn't closed. A short check-in with a pest control expert at that point frequently saves weeks of frustration.

A short, practical list to identify and act

Measure hole size and depth, note mound presence, and picture for scale. Map where holes occur: open lawn, edges, along slabs, near beds, or under structures. Check timing: fresh holes at dawn, night video camera activity, seasonal patterns. Test the lawn: tamp mole runs, refill small holes lightly, see what reopens. Decide on targeted action: trapping, exemption, or habitat/food adjustment, and set a one to two week review.

Final ideas from the field

The ground informs the story if you decrease and read it. A lot of property owners start with an item and end with a guess. Flip that. Make a clean recognition, then utilize the lightest effective touch. When the damage indicate a denning animal or stinging bugs near traffic, bring in a professional with the right tools. If you keep your lawn healthy, remove easy calories, and close structural spaces, you'll invest far less time chasing after animals and more time delighting in the space. And if something brand-new starts digging next season, you'll know how to listen to the backyard and catch the offender quickly.
