Squirrels digging up your lawn can ruin grass, disturb roots, and create unsightly mounds. You don’t have to live in constant fear of furry invaders. This guide offers practical, step-by-step solutions—from natural deterrents to physical barriers—to protect your lawn while keeping wildlife safe. Learn how to identify squirrel behavior, choose the right repellent, and make your yard less appealing without harming these clever animals.
Have you ever stepped outside to admire your lush green lawn only to find it dotted with tiny, perfectly round holes? Or maybe you’ve seen raised mounds of soil near trees or garden beds? Chances are, you’re dealing with squirrels. These energetic critters are adorable, sure—but when they start turning your yard into a personal excavation site, the damage adds up fast.
Squirrels dig not just for fun—they’re foraging for grubs, roots, seeds, and anything edible beneath the surface. But their digging can seriously harm your lawn’s health. Each hole disrupts root systems, creates bare patches, and invites weeds or invasive plants to take hold. Plus, repeated digging leads to soil compaction and erosion.
The good news? You can protect your lawn using humane, science-backed strategies. In this guide, we’ll walk you through everything you need to know about how to keep squirrels from digging up your lawn—without resorting to traps or poisons.
Whether you’re dealing with a single busy squirrel or an entire neighborhood crew, these steps will help restore peace (and beauty) to your yard.
Key Takeaways
- Identify the problem: Squirrels dig for food, shelter, or to bury nuts—knowing why helps you target their behavior.
- Use scent-based repellents: Predator urine or strong-smelling herbs like garlic and cayenne pepper can scare squirrels away.
- Install physical barriers: Hardware cloth, wire mesh, or underground fencing prevents access below ground level.
- Remove attractants: Keep bird feeders clean and store compost securely to reduce temptation.
- Plant squirrel-resistant grass: Choose tough, deep-rooted grass varieties that recover quickly from digging damage.
- Encourage natural predators: Owls, hawks, and snakes help control populations—create habitats that support them.
- Be consistent: Repellents wear off; combine multiple methods for long-term success.
Why Do Squirrels Dig Up Lawns?
Understanding squirrel behavior is the first step to solving the problem. Unlike gophers or voles, squirrels aren’t typically burrowers. Instead, they dig shallow holes—usually 6 to 12 inches deep—in search of food.
Common reasons include:
– Hunting for grubs and beetles in the soil
– Burying and retrieving acorns, walnuts, or seeds
– Creating nesting spots under patios or sheds
– Marking territory by scratching at the ground
They’re especially active in fall and spring when food sources are scarce. And once they discover your lawn has tasty treats, they won’t hesitate to return.
If you notice digging concentrated near tree roots, flower beds, or areas near bird feeders, those are likely hotspots. Squirrels prefer soft, moist soil that’s easy to excavate.
Step 1: Remove Food Sources
Before applying repellents or building fences, eliminate what’s drawing squirrels to your lawn in the first place.
Start by inspecting your property for potential food supplies:
– Clean up fallen fruit from trees (especially oaks and maples)
– Secure compost bins with tight-fitting lids
– Store pet food indoors overnight
– Use squirrel-proof bird feeders or relocate them far from your house
Even small crumbs near outdoor tables or barbecue areas can attract curious critters. A tidy yard makes your space less inviting.
For example, if you’ve got a favorite oak tree dropping acorns every autumn, consider planting a barrier—like chicken wire draped over the base—to catch falling nuts before they hit the ground. That way, squirrels won’t feel tempted to dig nearby.
Also, avoid fertilizers high in nitrogen during peak squirrel season. While not directly eaten by them, such nutrients boost grub populations—which are squirrel favorites.
By cutting off the buffet, you reduce the urge to dig significantly.
Step 2: Apply Natural Repellents
Repellents work best when used consistently and combined with other tactics. The goal isn’t to kill—just to make your lawn smell or taste unpleasant.
Try these natural options:
Predator Urine Sprays
Products containing fox or coyote urine mimic the scent of a predator nearby. When squirrels detect this, they assume danger and leave. Reapply after rain or heavy watering since UV rays and moisture break down the compounds quickly.
Look for brands like “Liquid Fence” or “Bobbex,” which are safe for lawns but effective on mammals. Spray along borders, near holes, and around garden edges. Avoid spraying directly on grass clippings or mulch unless labeled safe.
Hot Pepper Solutions
Mix one cup of cayenne pepper, one tablespoon of dish soap, and four gallons of water in a spray bottle. Shake well and apply to affected areas. The capsaicin irritates squirrels’ sensitive snouts, discouraging repeat visits.
Note: This may temporarily affect beneficial insects, so use sparingly and avoid spraying during bloom periods.
Garlic and Onion Sprays
Crush several garlic cloves and steep them in water for 24 hours. Strain and dilute with more water before spraying. Squirrels dislike the strong odor, though human noses barely register it.
These sprays also act as mild fungicides—a bonus for lawn health.
Always test any new spray on a small patch first. Some grasses (like St. Augustine) are sensitive to acidic solutions.
Step 3: Install Physical Barriers
Sometimes smells aren’t enough. That’s where physical barriers come in.
Underground Fencing
Since squirrels dig upward, install fencing below ground level. Use hardware cloth (at least 12-gauge) buried 8–10 inches deep around vulnerable zones like vegetable gardens or young trees.
Anchor the mesh vertically with stakes every few feet. Extend it above ground by another 6 inches to prevent climbing over.
For larger yards, consider electric fencing powered by a low-voltage charger. A quick zap deters most animals without causing lasting harm.
Raised Garden Beds
If you grow edibles, build beds at least 18 inches tall with smooth sides (like recycled plastic or treated wood). Squirrels struggle to climb slippery surfaces, especially when wet.
Pair this with netting during seedling stages for extra protection.
Tree Guards
Wrap trunks of fruit or ornamental trees with smooth PVC tubing or metal guards. This stops squirrels from accessing bark, sap, or roots—and reduces digging near the base.
Make sure guards extend 1–2 feet above and below the soil line.
Remember: Physical barriers work best when installed before damage occurs. If squirrels already know your yard is rich with food, they’ll test boundaries aggressively.
Step 4: Modify Your Lawn Environment
Make your lawn less appealing structurally and aesthetically.
Overseed Damaged Areas
After squirrels move on, overseed bare spots with drought-tolerant grass blends. Fast-growing fescues or Kentucky bluegrass recover quickly and fill gaps before weeds invade.
Water deeply but infrequently to encourage strong root growth—this makes future digging harder and less rewarding.
Aerate Compact Soil
Compacted soil is easier for squirrels to dig through. Aerate annually using a core aerator to create channels for air, water, and nutrients. Healthy turf resists erosion and recovers faster from disturbance.

Introduce Competing Burrows
Squirrels avoid areas where others have established dens. Encourage groundhog activity (yes, even though they’re pests) by placing brush piles or rock stacks away from high-traffic zones. Their presence signals “occupied territory.”
Alternatively, install owl boxes or kestrel perches. Birds of prey naturally keep squirrel numbers in check. Just ensure nesting sites aren’t too close to your home.
Step 5: Use Visual and Auditory Deterrents
Squirrels rely heavily on sight and sound. Harassment techniques exploit their wariness.
Motion-Activated Devices
Sprinklers or ultrasonic repellers trigger when movement is detected. A sudden burst of water startles squirrels and washes away scent trails. Solar-powered models are eco-friendly and cost-effective.
Place sprinklers near entry points or frequently used paths. Angle them so they cover digging zones but spare desirable areas like flower beds.
Reflective Surfaces
Hang old CDs, aluminum pie plates, or commercial scare balloons filled with holographic foil. Glare confuses and irritates squirrels, making them think something dangerous is nearby.
Move these items weekly—squirrels adapt quickly to static objects.
Fake Predators
Temporarily place owl decoys or rubber snakes near problem areas. Replace them often or rotate positions to maintain surprise value.
Combine with motion-activated lights for maximum effect.
Remember: These tools work only if introduced early and maintained regularly.
Troubleshooting Common Issues
Even with perfect planning, squirrels sometimes persist. Here’s how to handle setbacks:
Problem: Repellents lose effectiveness after a few days.
Solution: Rotate between different types (scent, taste, visual). Never rely on one method alone.
Problem: Squirrels dig in the same spot repeatedly.
Solution: Cover the area temporarily with plywood or landscape fabric until vegetation regrows. Fill holes loosely—they’ll collapse and discourage reuse.
Problem: Damage spreads to neighboring yards.
Solution: Coordinate with neighbors on shared deterrents like communal bird feeder bans or synchronized repellent applications.
Problem: Young squirrels appear injured or abandoned.
Solution: Observe from a distance. Mother squirrels often return within hours. Only intervene if you see blood or obvious distress.
Problem: Grass dies after repellent application.
Solution: Dilute solutions further or switch to non-toxic options like vinegar-water mixtures (test first!).
Consistency beats intensity every time. Most homeowners see results within 2–4 weeks of combining multiple approaches.
Long-Term Lawn Care Tips
Prevention is always better than repair. Maintain a resilient lawn year-round:
– Mow regularly at recommended heights (don’t scalp the grass)
– Fertilize based on soil test results—avoid excess nitrogen
– Water deeply once or twice weekly rather than daily
– Leave grass clippings on the lawn (they decompose into natural fertilizer)
A thick, healthy turf leaves little room for grubs or weeds—and fewer rewards for digging squirrels.
