Chipmunks usually leave when your yard becomes less rewarding. Remove food, reduce cover, block access, and use deterrents to make the space feel less safe for them.
A mix of cleanup, exclusion, and humane deterrents works best. One practical guide recommends removing attractants first, then adding barriers and repellents.
Remove What Attracts Them
Chipmunks go where food is easy and shelter is close. If you take away those basics, you make your yard far less appealing and help prevent chipmunks from settling in.
Cut Off Birdseed, Pet Food, And Fallen Produce
Bird feeders, spilled seed, pet bowls, and dropped fruit attract chipmunks. Clean under feeders often and store pet food indoors. Pick up fallen produce before it piles up.
If you use birdseed, choose feeders that limit spillage and keep the ground tidy.
Clear Brush, Woodpiles, And Dense Ground Cover
Chipmunks want cover to hide. Trim thick shrubs and rake leaf litter.
Move firewood off the ground or into a covered area. Less clutter means fewer hiding spots.
Spot Signs Of Active Chipmunk Burrows
Look for small entrance holes, fresh loose soil, and paths running along fences or foundations. Active chipmunk burrows often appear near beds, decks, and dense plantings.
If you find them early, you can respond before the digging spreads.
Use Reliable Deterrents
Deterrents work best when your yard is already less attractive. Combine a chipmunk repellent with cleanup and barriers for the strongest results.
Choose A Chipmunk Repellent For Garden Hotspots
Apply chipmunk repellents around beds, bulbs, entry points, and other high-traffic spots. Products with strong scents or tastes, such as garlic or hot pepper, can discourage feeding and digging.
Reapply after rain or heavy watering so the effect lasts.
When Chipmunk Repellents Help And When They Don’t
Chipmunk repellents can make a garden less tempting, especially when activity is light or limited to a few areas. They do not fix a food or shelter problem alone.
If the yard still offers shelter and snacks, chipmunks may ignore the scent and return.
Try Peppermint Oil And Other Scent-Based Options
Peppermint oil is popular because the smell is strong and easy to apply in targeted spots. Some gardeners use eucalyptus or mint plantings near beds.
A 2026 roundup of natural peppermint oil repellents found these options help as part of a broader plan.
What To Know About Ultrasonic Repellents
Ultrasonic repellents use high-pitched sound to make areas less comfortable for chipmunks. They may help indoors or in protected spaces.
Results in open gardens can be inconsistent. Use them as one tool among several.
Block Access To Gardens And Structures
Chipmunks stay if they can dig under, squeeze through, or nest near your home. Physical barriers protect the places you care about most.
Install Mesh Barriers Around Beds And Bulbs
Place hardware cloth or fine mesh around raised beds, bulbs, and vulnerable plants. Bury the edge several inches deep so chipmunks cannot dig beneath it.
This protects specific garden spots.
Seal Gaps Under Decks, Patios, And Foundations
Close openings where chipmunks might hide or nest, especially under decks, patios, sheds, and foundations. Small gaps can become shelter sites if left open.
A sealed structure removes an easy reason for chipmunks to linger.
Protect Outdoor Spaces Including A Catio
If you have a catio, keep it enclosed so chipmunks cannot enter or nest nearby. The same idea applies to porches, pet areas, and play spaces.
Cover every access point for best results. A secure layout makes your yard feel less like open territory.
Handle Ongoing Activity Humanely
If chipmunks are already active, a humane approach keeps your yard workable without causing harm. The goal is to discourage return visits and reduce the conditions that keep them there.
When To Fill Old Tunnels And Monitor New Digging
Fill unused tunnels only after you are sure they are inactive. If you pack down an active burrow too soon, the chipmunk may reopen it or dig elsewhere nearby.
Watch for new soil piles or fresh holes so you can spot patterns quickly.
How To Move Chipmunks Legally And Safely
Check your state and local rules before you try to move chipmunks. Safe handling matters, because stress and bites are real risks.
If relocation is allowed, use humane methods and follow local guidance.
Know When Professional Help Makes Sense
If chipmunks keep returning despite cleanup, repellents, and barriers, you may need a wildlife control professional. This is especially important when burrows are near foundations, patios, or other structures you need to protect.
A pro can help you get rid of chipmunks and prevent the problem from turning into a bigger repair job.
