What Animals Live In Holes In The Ground

If you’ve ever noticed a mysterious hole in your garden soil, you’ve probably wondered what animals live in holes in the ground. These underground dwelling creatures are more than just curious sights; they play a huge role in the health of your yard’s ecosystem. Understanding who’s down there can help you decide if they’re a friend or a foe to your plants.

From tiny insects to sizeable mammals, a whole community lives beneath our feet. Their burrows provide shelter from weather and predators, a safe place to raise young, and often, storage for food. Let’s get to know your subterranean neighbors.

This list covers the most common hole-diggers you might encounter. Some are solitary, while others live in complex social colonies right under your lawn.

Mammals That Burrow

These furry engineers are often the ones creating the most noticeable holes and mounds.

Groundhogs (Woodchucks): These large rodents create extensive burrow systems with multiple entrances. They’re famous for their digging skills and can move an incredible amount of soil. A groundhog hole is usually a hefty 10-12 inches wide with a big mound of dirt at the entrance.
Moles: Moles don’t actually live in the holes you see. They create shallow surface tunnels for hunting earthworms and insects. Their distinctive “molehills” are piles of soil pushed up from deeper, permanent living tunnels. They’re insectivores, not plant-eaters, but their tunneling can disturb roots.
Gophers (Pocket Gophers): Often confused with moles, gophers are rodents that eat plant roots. They create fan-shaped mounds of fine soil as they dig their deep tunnels. Their holes are typically plugged with dirt, unlike mole tunnels.
Rabbits: Wild rabbits, like cottontails, often use existing holes or dig simple, shallow depressions called forms. Other species, like the European rabbit, dig more complex warrens with many interconnected tunnels and rooms for their family groups.
Skunks & Raccoons: These clever animals are usually opportunists. They rarely dig their own homes from scratch. Instead, they will happily move into an abandoned burrow made by another animal and expand it to suit there needs.

Reptiles and Amphibians

Many cold-blooded creatures rely on burrows to regulate their temperature and stay hidden.

Gopher Tortoises: A keystone species in the southeastern US, their deep, wide burrows provide shelter for over 350 other species! Their burrows can be up to 40 feet long and 10 feet deep.
Many Snakes: Species like pine snakes, rattlesnakes, and kingsnakes are excellent burrowers. They often take over rodent holes for nesting or hibernation. A snake hole is usually a simple, clean round entrance without much loose dirt around it.
Toads: Common toads will dig backwards into soft soil to create a temporary home. They use their strong hind legs to settle in just below the surface, where the soil is cooler and moister during the day.

Birds That Nest Underground

Not all birds nest in trees. Some species prefer the safety of a subterranean home.

Burrowing Owls: These small, long-legged owls are famous for living in old prairie dog or ground squirrel burrows. They’ll often line the entrance with manure to attract insects for easy eating and can be seen standing guard at their hole entrances.
Bank Swallows & Kingfishers: These birds excavate tunnels in sandy banks, usually near water. They use their beaks and feet to dig out long nesting chambers at the end of the tunnel, where they raise their chicks safe from most predators.

The Insect World

The most numerous underground architects are insects. Their colonies can be massive and highly organized.

Ants: Ant colonies are intricate underground cities with chambers for nurseries, food storage, and the queen. The loose soil “anthills” we see are just the tip of the iceberg from their constant excavation work.
Ground Bees & Wasps: Many solitary bee species, like miner bees, dig small individual burrows in bare, sandy soil. Some wasps, such as the cicada killer wasp, also dig burrows to paralize prey and lay eggs on.
Cicada Nymphs: These insects spend most of their lives—2 to 17 years!—underground as nymphs. They live in small chambers, feeding on sap from tree roots before emerging to molt into adults.
Earthworms: While not technically diggers, earthworms are vital “tunnelers.” They create burrows by eating their way through the soil, which provides crucial aeration and drainage for your garden beds.

Identifying the Hole’s Owner

Before you take any action, try to identify the animal. Here’s a quick guide based on the hole itself:

Large hole (10+ inches) with a big mound: Likely a groundhog, badger, or fox.
Volcano-shaped mound of fine soil: A classic gopher sign.
Raised ridge of soil snaking across the lawn: Surface mole tunnels.
Neat, round hole (2-3 inches) with no mound: Could be a snake or a entrance to a chipmunk burrow.
Many small holes in a sandy patch: Probaby solitary bees.
Small hole surrounded by a dirt “apron”: Often the work of a digging squirrel looking for buried nuts.

Living with Underground Neighbors

Most burrowing animals are beneficial. They aerate soil, control pest insects, and help with seed dispersal. Here’s how to manage them if they become a nusiance.

For Insect Control:

For ground bees, simply keeping the soil moist or lightly covering bare patches with mulch can discourage nesting.
For ant hills, locate the main nest and use boiling water or a targeted, eco-friendly bait.

For Larger Mammals:

Exclusion: Install a buried fence (at least 1 foot deep and bent outward) to protect specific garden areas.
Habitat Modification: Remove brush piles, seal off crawl spaces, and keep grass trimmed to reduce cover.
Natural Deterrents: Sprinkle cayenne pepper or use commercial repellents around hole entrances. Castor oil-based sprays applied to the lawn can make grubs and worms taste bad to moles and gophers.
Live Trapping: For persistent problems, use a live trap baited with vegetables for herbivores like groundhogs. Always check local regulations first, as many species are protected.

Remember, filling a hole without adressing the resident is temporary. They are excellent diggers and will simply reopen it. The key is to make the area less attractive first.

When to Call a Professional

If you suspect the animal is:

A venomous snake or a threatened species (like a gopher tortoise).
Causing significant structural damage near your home’s foundation.
Persistent and none of your deterrents are working.

A licensed wildlife control operator can humanely and legally handle the situation. They have the right tools and knowlege to do it safely.

FAQ

What animal is digging small holes in my yard at night?
This is often the work of raccoons or skunks looking for grubs. You’ll see torn-up patches of grass, not neat holes. Armadillos, in some regions, also dig cone-shaped holes for insects at night.

Are holes in the ground bad for my garden?
Not always. Holes improve drainage and soil aeration. The problem arises when plant roots are disturbed or when the digging becomes excessive and creates tripping hazards or ruins lawns.

How deep do animal burrows go?
It varies widely. A mole’s deep tunnel might be 10 inches down, while a groundhog or badger burrow can go 5 feet deep or more, with chambers for sleeping and raising young.

What makes holes in the ground with no mound?
Clean holes often indicate an animal that doesn’t excavate dirt, like a snake using an existing hole. Squirrels sometimes dig and then cover their holes poorly, leaving a shallow depression. Insects like cicadas also emerge from holes without mounds.

Getting to know the animals that live in holes in the ground gives you a better appreciation for the hidden activity in your garden. Often, the best approach is a bit of tolerance. These creatures are part of natures intricate web, working the soil and contributing to a healthy, living landscape right outside your door.
