Ever wondered what chipmunks do with all that dirt when they dig a hole? You rarely see big messy piles near their burrows, right?
Chipmunks actually carry the dirt away in their cheek pouches, then scatter it far from their holes. It’s a sneaky move that keeps their homes hidden and safe from predators.
You might spot small holes in your yard but never see the telltale mounds you’d expect from other digging animals. That’s because chipmunks work hard to avoid leaving obvious dirt piles by their tunnels.
Understanding how they handle the dirt can help you figure out what’s happening in your yard. You’ll probably get a better sense of these clever little creatures if you pay attention to the details.

What Chipmunks Do With the Dirt When Digging Holes
Chipmunks move a surprising amount of soil when they dig their burrows. But they don’t just dump it next to the entrance.
They’ve come up with clever ways to spread and hide the dirt. This trick makes it tough for anyone—especially predators—to spot their burrows.
Techniques Chipmunks Use to Remove Dirt
Chipmunks stuff soil into their cheek pouches, just like they do with food. It’s kind of wild to think their cheeks have double duty.
They haul small loads of dirt out of the tunnel, bit by bit. Once above ground, they scatter the dirt over a wide area instead of leaving a pile.
This keeps the entrance less obvious. Predators or curious animals have a harder time noticing anything unusual.
Chipmunks dig straight down at first, then branch out sideways to create tunnels and little rooms. Each bit of dirt gets carried out carefully so nothing gives away their hiding spot.
How Chipmunks Disperse Excavated Soil
You won’t find big mounds like you do with molehills or rabbit burrows. Chipmunks spread the dirt in a thin, subtle layer.
Sometimes you’ll notice loose soil scattered in patches near the burrow. They do this to keep things discreet and avoid drawing attention.
Wind and rain can break up the dirt even more, making everything blend in. The area stays natural-looking, and the chipmunks stay safer.
Differences From Rabbits, Groundhogs, and Moles
Rabbits and groundhogs dig burrows too, but they handle dirt differently. Rabbits push soil out and leave big, obvious mounds.
Groundhogs make even bigger hills around their homes. Moles leave those classic molehills—big piles of dirt right by their tunnels.
Chipmunks, though, spread their dirt thin and flat. If you see small, flat holes with dirt scattered around, you’re probably dealing with chipmunks instead of rabbits or moles.
This little detail can help you figure out which critter is living near your house.

Understanding Chipmunk Burrow Systems and Impacts
Chipmunk burrows are surprisingly tidy and organized. They dig several tunnels and little chambers, each with a purpose.
You’ll usually find these burrows in spots where chipmunks can stay safe and stash food. Their digging can mess with your garden or lawn, but knowing what to expect makes it easier to deal with.
Structure of Chipmunk Burrows and Tunnels
Most chipmunk burrows have tunnels about 2-3 inches wide. Some go as deep as three feet and stretch up to 30 feet long.
Inside, you’ll find pockets for storing food, spots for going to the bathroom, and a cozy area for nesting or raising babies. Burrows often have more than one entrance, and chipmunks sometimes plug up old ones.
Drainage tunnels at the bottom keep things dry. This setup helps chipmunks survive winter and stay hidden.
Because chipmunks dig close to the ground without leaving mounds, you might not notice their burrows until you spot an entrance or some damage in your yard.
Common Locations for Chipmunk Holes in Gardens and Lawns
You’ll often see chipmunk holes near wood piles, bushes, or at the edge of gardens. These places offer cover and food like nuts or seeds.
Chipmunks like loose soil for easier digging. Lawns with shade or near tree roots are popular too.
Their holes look like small, flat openings on the ground—no mounds. If you spot several small holes in your garden, chipmunks might have moved in.
If you want to discourage them, try using gravel borders or clearing away piles of rocks and debris.
Comparison With Squirrels and Other Rodents
Unlike squirrels, chipmunks stick to the ground. Squirrels build nests in trees, but chipmunks dig underground.
Their tunnels are smaller and have more chambers than mole tunnels. Moles leave raised mounds, while chipmunks keep things flat.
Squirrels hide food in tree branches or bury it, but chipmunks store food inside their burrows. Chipmunks live alone most of the time, except when raising babies.
Their homes are simple compared to some rodents’ shared tunnels, but still have plenty of little chambers for different uses.
Garden and Property Effects of Chipmunk Digging
Chipmunks loosen soil when they dig, which sometimes helps aerate a garden. Still, they can mess up flower beds, vegetable patches, or even the roots of your lawn.
Their burrows leave holes that make the ground uneven. You might even trip if you aren’t watching your step.
Most of the time, chipmunks don’t cause major structural damage. They usually stick to messing with gardens or yards.
Try filling their holes with gravel—chipmunks find it tough to tunnel through that. If you just use dirt, they’ll probably dig it up again.
Want to keep them away? You could plant daffodils or allium, or maybe put up some fencing. Clearing away debris where chipmunks hide also makes your place less inviting to them.
