Chipmunks Are Cuter Than They Are Harmless — Here’s How to Fix That

If you need to get rid of chipmunks permanently, here’s the short version:

Remove food sources – clean up birdseed, fallen fruit, and accessible pet food
Eliminate shelter – clear woodpiles, rock piles, and dense ground cover
Use live traps – bait with sunflower seeds or peanut butter near burrow entrances
Install exclusion barriers – bury 1/4-inch hardware cloth in an L-shape around foundations and garden beds
Apply repellents – use peppermint oil, predator urine, or capsaicin sprays at entry points
Call a professional – for persistent or large infestations, an integrated approach gets lasting results

They look harmless. But one chipmunk can quickly become twenty. A single urban yard can support up to 20 chipmunks when food is plentiful — and their burrow systems can stretch over 30 feet underground, threatening patios, foundations, and garden beds.

Most homeowners notice a few chipmunks near a bird feeder and don’t act right away. By the time the damage shows up — raised sidewalks, uprooted bulbs, chewed wiring, or water backup from clogged downspouts — the population has already grown.

The good news: chipmunk infestations are very manageable when you tackle them the right way.

I’m Mat Ledyard, owner of Black Dog Pest Solutions in Avon, Ohio, with nearly 20 years in the pest control industry helping Northern Ohio homeowners get rid of chipmunks permanently alongside other rodent and wildlife challenges. In this guide, I’ll walk you through every proven tactic — from simple prevention to professional exclusion — so you can stop the damage for good.

Identifying the Signs of a Chipmunk Infestation

Before you can formulate a plan to get rid of chipmunks permanently, you have to know what you’re up against. In Northern Ohio, from Greater Cleveland to Sandusky, chipmunks are incredibly active in the spring and fall. While they might look like tiny squirrels with racing stripes, their behavior is much more grounded—literally.

Unlike tree squirrels, chipmunks spend the vast majority of their time in complex underground burrow systems. These tunnels can be over 30 feet long and include specialized chambers for sleeping, “trash” disposal, and food storage. One chipmunk alone can store over 8 pounds of food in its larder!

Signs of an infestation often start in the yard. You might notice small, clean-cut holes about 2 inches in diameter. Unlike moles or gophers, chipmunks are tidy; they carry away the excavated dirt in their cheek pouches and dump it elsewhere to keep the entrance hidden. If you see these holes near your foundation, stairs, or stone walls, you have a problem.

The damage isn’t just aesthetic. According to research on chipmunk damage prevention, while the economic loss is often under $200, the structural risks are real. Burrowing under patios and sidewalks can cause the ground to settle, leading to cracked concrete or undermined porches. In some cases, they’ve even been known to gnaw on electrical wiring or clog downspouts with nesting material. If you suspect they’ve moved from the yard to your crawlspace, check out our residential rodent services for expert help.

Recognizing Burrow Entrances

Identifying a chipmunk hole is a bit of a detective game. Look for tunnel openings near “backdrops”—places like woodpiles, stumps, or the edges of your home’s foundation. Because they don’t leave mounds of dirt, these holes can look like simple gaps in the soil. However, if you see multiple holes within a small radius, or if your porch feels hollow when you step on it, you’re likely looking at an active colony.

Garden and Landscape Damage

Your garden is often the first victim. Chipmunks love to dig up freshly planted flower bulbs (especially tulips) and snack on strawberries or tomatoes. They also gnaw on the bark of young shrubs and raid bird feeders with surgical precision. It’s easy to confuse their work with other pests; for instance, you can find more info about vole damage to see if those “meadow mice” are actually the ones ruining your lawn.

How to Get Rid of Chipmunks Permanently by Removing Attractants

If your yard is a buffet and a five-star hotel, the chipmunks aren’t going anywhere. To get rid of chipmunks permanently, you must change the environment. This is what we call habitat modification, and it’s the most important step in any expert guide on chipmunk control.

Managing Bird Feeders and Pet Food

Birdseed is the #1 reason chipmunks invade Ohio yards. They aren’t just eating the seed; they are hoarding it. To stop the cycle:

The 15-Foot Rule: Place bird feeders at least 15 feet away from any structures. This prevents chipmunks from using your house as a “jumping off” point or a nearby nesting site.
Switch Seeds: Use thistle (Nyjer) or safflower seeds. Birds love them, but chipmunks find them bitter and unappealing.
Clean Up: Use tray catchers under feeders to prevent seed from hitting the ground. If seed does fall, sweep it up daily.
Airtight Storage: Never leave bags of pet food or birdseed in the garage or on the porch. Chipmunks can chew through plastic and paper with ease. For more on keeping these critters out of your storage areas, see our mice prevention tips.

Eliminating Shelter and Harborage

Chipmunks hate being out in the open because it makes them vulnerable to hawks, foxes, and the occasional neighborhood cat. By removing their “cover,” you make your yard much less attractive.

Clear the Debris: Remove piles of rocks, firewood, and lumber. If you must store wood, keep it elevated off the ground.
Trim the Landscape: Avoid continuous ground cover (like ivy or heavy mulch) that leads directly to your home’s foundation. Keep your grass short and trim back low-hanging bushes.
Seal the Gaps: Check your foundation for any cracks or holes. A chipmunk can squeeze through a gap the size of a quarter.

Humane Trapping and Relocation Tactics

When prevention isn’t enough, trapping is often the fastest way to reduce a population. However, it’s rarely a “one and done” solution. Because chipmunk populations can reach 20 individuals per yard, you’ll need to be persistent.

Best Baits to Get Rid of Chipmunks Permanently

Choosing the right bait is key. While cartoon chipmunks love acorns, real-world chipmunks are suckers for high-protein, high-fat snacks.

Sunflower Seeds: These are the gold standard. They are familiar and easy for the chipmunk to smell.
Peanut Butter: Smear a little on the trigger plate. To make it even more effective, press a few sunflower seeds or bits of oatmeal into the peanut butter.
Cereal Grains: Plain Cheerios or pumpkin seeds also work well.

Pro Tip: “Pre-bait” the trap for 2-3 days. Place the bait inside but keep the doors wired open. This allows the chipmunks to get comfortable entering the trap without fear. Once they’re used to the “free meal,” set the trigger.

Proper Relocation Procedures

If you’re using live traps, you must check them at least twice a day. Leaving an animal in a trap for too long is inhumane and can lead to heat exhaustion. According to standard trapping reviews, you should always wear heavy leather gloves when handling the trap to protect yourself from bites and scratches.

For relocation to be effective, you need to take them far enough away that they won’t find their way back. A 5-mile radius is generally recommended. Look for wooded areas or parks (check local ordinances first, as some areas in Ohio restrict releasing wildlife on public land). That relocation is stressful for the animal; releasing them into a new territory where they don’t have a burrow or food cache can lead to high mortality rates.

Exclusion and Landscaping Barriers

If you want to get rid of chipmunks permanently, you have to physically block them from the areas they love most. This is the most “permanent” part of the process because it doesn’t rely on the animal’s behavior—it relies on solid engineering.

Material	Best Use	Effectiveness
1/4-inch Hardware Cloth	Foundations, gardens, under decks	High
Gravel Borders	Perimeter of house	Medium
Caulking/Expanding Foam	Small cracks and gaps	High
L-Shaped Footers	Preventing burrowing under patios	Very High

Professional Exclusion to Get Rid of Chipmunks Permanently

Exclusion is the process of “building them out.” At Black Dog Pest Solutions, we often help homeowners in Avon and Westlake seal up their homes.

L-Shaped Footers: This is the secret weapon against burrowing. You bury 1/4-inch galvanized mesh about 1 foot deep, then bend the bottom 6 inches outward in an “L” shape. When a chipmunk tries to dig down, it hits the mesh and gives up.
Foundation Sealing: Use a combination of copper mesh (which they hate to chew) and high-quality caulk or expanding foam to seal gaps around utility pipes and foundation vents.
Gutter Guards: Install mesh covers over your downspouts to prevent chipmunks from using them as “expressways” to your roof or attic. For more on keeping larger rodents out, see our rat exclusion guide.

Natural Repellents and Deterrents

Repellents can be a great “supplemental” tool. They won’t solve a massive infestation on their own, but they can make specific areas less appealing.

Peppermint Oil: High-menthol peppermint oil is very pungent to rodents. Soak cotton balls and place them in known burrow entrances.
Predator Urine: Fox or coyote urine (available in granules at garden stores) can trigger a flight response in chipmunks.
Taste Repellents: Sprays containing capsaicin (hot pepper juice) or Bitrex can be applied to flower bulbs and non-edible plants to stop gnawing.

Frequently Asked Questions about Chipmunk Removal

How do I handle a chipmunk that entered my home or attic?

If a chipmunk gets inside, it’s usually by accident. Open a window or door to provide an exit and leave the room. If it’s in the attic, you’ll need to use a live trap baited with peanut butter. Once the animal is out, you must find and seal the entry point—check the roofline, soffits, and vents. If you’re struggling to find the “door” they used, our team at Black Dog Pest Solutions can perform a full inspection.

Are mothballs or bleach effective for permanent removal?

In a word: No. Mothballs are toxic, bad for the environment, and generally ineffective against chipmunks, who will simply push them out of the burrow or dig around them. Bleach is even worse; it damages your soil and causes unnecessary suffering without solving the problem. Stick to proven exclusion and trapping methods for real results.

What plants naturally repel chipmunks from my garden?

You can use “nature’s fence” to protect your landscape. Chipmunks tend to avoid:

Daffodils: These bulbs are toxic and bitter.
Allium: The onion-like scent is a major turn-off.
Marigolds and Lavender: These have strong scents that interfere with the chipmunk’s ability to smell predators.

Conclusion

To get rid of chipmunks permanently, you have to be more persistent than they are. By combining habitat modification (removing the food and “hotels”) with physical exclusion and strategic trapping, you can reclaim your yard and protect your home’s foundation.

Chipmunk control isn’t a one-time event—it’s a strategy. Populations can rebound quickly if you let your guard down, especially in the lush environments of Northern Ohio. Whether you’re in Avon, Greater Cleveland, or over in Sandusky, staying on top of birdseed cleanup and foundation maintenance is key.
