What is the best way to stop squirrels from digging in my yard? The best way to stop squirrels from digging in your yard is to combine multiple methods, focusing on making your yard less attractive to them and actively deterring them from specific areas.
Squirrels digging in your yard can be a real nuisance. They excavate bulbs, disturb newly planted seeds, and create unsightly holes in your lawn. But don’t despair! With the right strategies, you can effectively deter squirrels and protect your garden. This comprehensive guide will walk you through proven methods to prevent digging and keep squirrels out, ensuring your yard remains a pleasant space.
Squirrels are clever creatures, driven by instinct and the search for food. Their digging behavior is primarily linked to burying and retrieving nuts and seeds, as well as seeking out grubs and insects. If your yard offers easy access to these food sources or provides a safe haven, you’re likely to see more digging activity.

Why Do Squirrels Dig in Yards?
To effectively combat squirrel digging, it’s crucial to grasp their motivations. Knowing why they dig helps us implement the most suitable squirrel deterrents.
- Food Storage (Caching): This is the most common reason. Squirrels bury nuts, seeds, and other food items to save for later. They have a remarkable memory for their stash locations, but they also dig randomly, sometimes forgetting where they’ve buried things, leading to more digging.
- Foraging for Food: Beyond burying, squirrels actively dig to find food already in the ground, such as bulbs, roots, insects, and grubs.
- Nesting and Burrowing: While less common for casual digging, squirrels might excavate shallow holes for temporary shelter or to access a more suitable nesting site.
- Exploration and Play: Young squirrels, especially, might dig out of curiosity or as part of their play.
Strategies to Deter Squirrels and Prevent Digging
Implementing a multi-pronged approach is key to successfully managing squirrel digging. We’ll explore various methods, from physical barriers to natural solutions.
1. Physical Barriers: Creating a Squirrel-Proof Garden
Physical barriers are some of the most effective ways to keep squirrels out of specific areas.
Protecting Garden Beds and Bulbs
- Netting and Wire Mesh:
- Cover newly planted areas or beds with fine-mesh netting or chicken wire. Ensure the mesh is small enough to prevent squirrels from getting through.
- You can lay chicken wire flat on top of the soil, burying the edges slightly. Squirrels dislike the feel of the wire under their paws.
- For bulbs, consider planting them in wire baskets or cages that allow the bulbs to grow but block the squirrels.
- Decorative Rocks and Mulch:
- Placing larger rocks or decorative stones around the base of plants can make digging more difficult.
- A thick layer of mulch, especially coarse or sharp mulch like pine cones or gravel, can be a deterrent. Squirrels prefer loose, easy-to-dig soil.
- Planting Depth:
- Plant bulbs at the recommended depth, or even a little deeper. The deeper the bulb, the harder it is for squirrels to reach.
Fencing Solutions
- Enclosure Fences: For highly prized areas, consider building a fenced enclosure. The fence should be at least 3 feet tall and ideally have an inward-facing overhang (about 6-12 inches) to prevent squirrels from climbing over. Burying the bottom edge of the fence a few inches into the ground helps prevent burrowing underneath.
- Electric Fencing: While more involved, low-voltage electric fencing can be a very effective squirrel deterrent. It delivers a mild shock that discourages them from crossing.
2. Repellent Options: Making Your Yard Unappealing
Using a squirrel repellent can make your yard a less attractive destination.
Natural Squirrel Repellents
Many gardeners prefer natural squirrel repellent options that are safe for pets and children.
- Strong Scents: Squirrels have sensitive noses.
- Peppermint Oil: Soak cotton balls in peppermint oil and place them around vulnerable areas. Reapply regularly, especially after rain.
- Cayenne Pepper/Chili Powder: Sprinkle cayenne pepper or chili powder on the soil around plants. The irritation to their paws and noses can deter squirrels. Reapply after watering or rain.
- Garlic and Onion: Planting garlic and onions amongst your flowers can also act as a deterrent due to their strong smell.
- Coffee Grounds: Used coffee grounds can be sprinkled around plants. The scent and texture can be off-putting.
- Predator Urine: Products containing the scent of fox or coyote urine can mimic the presence of predators, making squirrels feel unsafe. These are available commercially.
- Vinegar: Similar to strong scents, diluted vinegar can be sprayed on the soil. Be cautious, as too much vinegar can affect soil pH.
- Castor Oil: Castor oil is often cited as a natural squirrel repellent. It can be mixed with water and sprayed on plants or sprinkled on the soil. It’s thought to irritate their paws.
Commercial Squirrel Repellents
If natural methods aren’t strong enough, consider commercial repellents.
- Granular Repellents: These are typically made from ingredients like castor oil, predator urine, or essential oils. They are sprinkled on the soil.
- Spray Repellents: These can be applied directly to plants, bulbs, or the soil surface. Always follow product instructions carefully and ensure they are safe for your specific plants.
Important Note on Repellents: Repellents often need frequent reapplication, especially after rain or watering, to remain effective. Consistency is key.
3. Habitat Modification: Removing Attractions
Making your yard less appealing to squirrels can significantly reduce their digging activity.
Food Sources
- Secure Trash Cans: Use trash cans with tight-fitting lids. Squirrels are opportunistic feeders and will raid unsecured garbage.
- Clean Up Fallen Fruit and Nuts: Regularly remove any fallen fruit or nuts from your trees. These are prime food sources for squirrels.
- Bird Feeder Management: Bird feeders are a major attraction.
- Squirrel-Proof Feeders: Invest in feeders designed to deter squirrels. These might have weighted perches that close off access or be made of materials squirrels can’t chew through.
- Baffles: Install a squirrel baffle on the pole supporting your bird feeder. These are dome-shaped or cone-shaped covers that squirrels can’t get around.
- Placement: Hang feeders at least 10 feet away from any trees or structures that squirrels can jump from.
- Feeder Types: Consider offering safflower seeds, which many squirrels dislike, instead of sunflower seeds.
Shelter and Nesting Sites
- Trim Tree Branches: Trim branches that overhang your house or garden, as these can act as bridges for squirrels to access your yard.
- Seal Entry Points: Inspect your home, sheds, and garages for any holes or gaps that squirrels could use for nesting. Seal them with sturdy materials like wire mesh or metal flashing.
4. Companion Planting and Plant Choices
Certain plants can help deter squirrels naturally.
- Repellent Plants: Consider planting strong-smelling herbs and flowers that squirrels tend to avoid.
- Marigolds
- Mint (can be invasive, consider planting in containers)
- Onions
- Garlic
- Daffodils (toxic to squirrels if ingested)
- Peppermint
- Lavender
- Rosemary
- Native Plants: Opting for native plants that are less appealing to local squirrel populations can also be a strategy for a squirrel proof garden. Research plants that are known to be resistant to squirrel damage in your region.
5. Humane Squirrel Control Methods
When aiming to stop digging damage, humane methods are often preferred.
- Scare Tactics:
- Decoys: Plastic owls or snakes can sometimes startle squirrels, but they often become accustomed to them quickly. Move them around regularly.
- Motion-Activated Sprinklers: These devices release a burst of water when they detect movement. The sudden spray can be an effective deterrent without causing harm.
- Live Trapping (Use with Caution):
- Live traps can be used to catch squirrels. However, relocating squirrels can be problematic. They may struggle to survive in a new environment, and it might be illegal in your area. Check local regulations before using traps. If you do trap a squirrel, release it far from your property, in a suitable habitat.
6. Addressing Specific Digging Problems
Let’s look at how to tackle digging in specific areas.
Lawn Digging
- Compacted Soil: Squirrels are often attracted to lawns with compacted soil because it’s easier for them to dig. Aerating your lawn can make it less appealing.
- Grubs and Insects: If squirrels are digging for grubs, address any underlying grub or insect infestations in your lawn. Healthy soil with fewer pests will be less attractive.
- Covering Holes: After a squirrel has dug, fill the holes promptly and tamp down the soil. This discourages them from returning to the same spot and helps repair your lawn.
Vegetable Gardens
- Raised Beds: Raised garden beds can be more difficult for squirrels to access, especially if the sides are smooth and tall.
- Cover Crops: Planting cover crops after your main harvest can help protect the soil and prevent squirrels from finding exposed areas to dig.
7. Understanding Squirrel Behavior for Effective Exclusion
Squirrel exclusion involves preventing them from accessing areas where they cause damage. This requires observation.
- Identify Entry Points: If squirrels are getting into your attic or garden structures, the first step is to identify how they are gaining access. Look for chewed holes, loose siding, or gaps.
- Timing is Key: If you need to seal entry points, do so when squirrels are not inside. This usually means during the day when they are out foraging. Sealing them in can lead to them causing more damage to escape or to die inside.
- Seal Thoroughly: Use strong, chew-proof materials like heavy-gauge wire mesh, metal flashing, or steel wool (packed into small holes) to seal any openings.
Squirrel Proof Garden: A Long-Term Strategy
Creating a squirrel proof garden is an ongoing effort that involves a combination of the strategies discussed above. It’s about making your yard a less desirable place for them to dig and forage.
- Consistent Maintenance: Regular upkeep, such as cleaning up fallen debris and securing food sources, is crucial.
- Layered Defenses: Don’t rely on a single method. A combination of barriers, repellents, and habitat modification is most effective.
- Patience and Observation: Observe squirrel activity in your yard to understand their habits and pinpoint problem areas. This will help you tailor your approach.
Troubleshooting Common Squirrel Digging Issues
Here’s a look at specific problems and solutions:
| Problem Area | Common Causes | Effective Solutions |
|---|---|---|
| Flower Beds | Bulb theft, general digging for food | Netting, chicken wire, coarse mulch, repellent plants (marigolds, garlic), castor oil spray, predator urine granules. |
| Vegetable Patch | Eating vegetables, digging for roots/insects | Raised beds, fencing with overhang, netting over plants, repellent sprays (chili pepper), companion planting (garlic, onions). |
| Lawn | Digging for grubs, burying/retrieving nuts | Aeration, grub treatment, covering holes promptly, sprinkling cayenne pepper or coffee grounds on the surface. |
| Potted Plants | Digging in pots, eating bulbs/plants | Place marbles, pine cones, or small rocks on the soil surface, use wire mesh cut to fit the pot, liquid deterrent sprays. |
| Attic/Sheds | Nesting, seeking shelter | Squirrel exclusion by sealing all entry points with metal flashing or hardware cloth, trimming overhanging branches, ensuring no food sources are easily accessible nearby. |
Frequently Asked Questions (FAQ)
Q: Will commercial squirrel repellents harm my plants?
A: Most commercial repellents are designed to be safe for plants when used according to the manufacturer’s instructions. However, it’s always a good idea to test a small area first or to apply them to the soil rather than directly on the foliage of sensitive plants, especially those with edible parts.
Q: How often do I need to reapply natural squirrel repellents like cayenne pepper?
A: Natural repellents, especially those sprinkled on the soil, need frequent reapplication. After rain, heavy dew, or watering, the scent can dissipate, reducing their effectiveness. Aim to reapply every few days or after significant weather events.
Q: Can I use mothballs to deter squirrels?
A: While mothballs are sometimes suggested as a deterrent, they contain naphthalene, which is toxic to pets, children, and wildlife. Their use is often discouraged due to environmental concerns and potential health risks. Safer, more humane alternatives are widely available.
Q: My neighbor’s bird feeder attracts squirrels to my yard. What can I do?
A: While you can’t control your neighbor’s feeder, you can make your yard less appealing. Ensure your own yard is free of easy food sources. If squirrels are regularly traveling from your neighbor’s yard to yours, discuss the issue politely or focus on making your property uninviting to them.
Q: Are there any humane ways to permanently stop squirrels from digging?
A: “Permanently” is a strong word when dealing with wildlife, as they are persistent. However, a consistent application of humane squirrel control methods, including making your yard unattractive and using physical deterrents, can significantly reduce their digging activity over the long term. It requires ongoing effort.
By implementing these strategies, you can effectively stop digging damage and enjoy a beautiful, intact yard. Remember that consistency and a combination of methods are your best allies in the ongoing battle against persistent garden invaders.
