Chipmunks live underground, and for many species, burrows serve as their main home. They also spend time above ground foraging, checking for danger, and moving between feeding spots.
Chipmunks use underground spaces for shelter, nesting, food storage, and protection. They come up when they need to gather seeds, nuts, and other food.
The Short Answer And How They Use Underground Homes
The eastern chipmunk, or Tamias striatus, is one of the best-known burrowers in North America. Other burrowing chipmunks include the Siberian chipmunk and the least chipmunk, and all of them rely on underground cover in different ways.
Why Burrows Are Their Main Shelter
Burrows provide chipmunks with a safe place to sleep, nest, store food, and avoid predators. These tunnels act as full homes with nesting and storage areas.
When They Stay Above Ground Versus Below Ground
You often see chipmunks above ground when they forage, travel, or stay alert to danger. They spend far more time below ground during cold months, and many eastern chipmunks use their burrows through winter.
Species That Commonly Burrow
The eastern chipmunk is a classic example of a burrowing species. The Siberian chipmunk also digs tunnels, and the least chipmunk uses underground shelter when needed.
What A Chipmunk Burrow Looks Like
A chipmunk burrow is usually neat and compact, not a random open hole. You may notice a small plunge hole at the surface, while most of the burrow stays hidden below ground.
Entrance Size And Depth
A chipmunk burrow entrance is often just a few inches wide, making it easy to miss in leaf litter or grass. Some burrows reach several feet deep and can run many feet long, especially in favorable soil.
Hidden Openings And Escape Routes
Many chipmunk burrows have more than one opening, which helps the animal escape quickly if threatened. Hidden exits and plunge holes give chipmunks a fast route into the safety of the tunnel system.
Nest Chambers Food Caches And Drainage Tunnels
Inside chipmunk burrows, you may find a nest chamber lined with grass or leaves, plus storage pockets for seeds and nuts. Some burrows include drainage tunnels or sloped passages that help keep the nesting area drier after rain.
Where They Dig And How To Recognize Yard Activity
Chipmunks dig where they can find cover, loose soil, and nearby food. You are more likely to notice chipmunk holes along borders, under shrubs, or near stonework than in the middle of an open lawn.
Common Spots Near Homes And Gardens
Near homes, chipmunks often choose mulched beds, brushy edges, retaining walls, and the ground beside foundations. They also like garden margins where roots, bulbs, and seeds are easy to reach.
How To Tell Their Holes From Other Animal Holes
Chipmunk holes are usually small, round, and tidy. Unlike larger animal burrows, they often leave little loose soil around the opening, so a clean entrance with little debris is a strong clue.
Why There Is Usually No Dirt Mound
Chipmunks often carry soil away from the entrance while digging or spread it out as they work. That is why chipmunk holes may look neat even when the tunnel system is active.
When Burrows Become A Problem And What To Do
Most chipmunk burrows cause no harm, especially when they are far from structures. Problems usually start when burrowing affects plants, patios, or the soil near your foundation.
Common Concerns Around Plants Patios And Foundations
Chipmunks can damage seedlings, bulbs, and fruit in garden areas, and their digging may loosen soil near patios or foundations. That is where burrows can become a practical concern instead of just a wildlife sighting.
When To Leave Them Alone
If the burrow is away from your home and you are not seeing plant loss or structural issues, leaving it alone is often the easiest choice. Chipmunks play a role in the yard ecosystem, and a single burrow does not always mean a bigger problem.
Humane Ways To Get Rid Of Chipmunks
If you need to get rid of chipmunks, start with humane steps.
Reduce food attractants and clear excess cover.
Use live traps only where legal and appropriate, as noted by Know Animals.
If the activity continues, a wildlife professional can help you handle it without harsh methods.
