Why Squirrels Dig
To effectively stop squirrels from digging, it helps to know why they do it. Squirrels are driven by instinct and necessity.
Food Storage Habits
Eastern Gray Squirrels, and many other common species, are notorious for burying nuts and seeds as a food source for leaner times. Your lawn, with its soft soil, is an ideal pantry. They will dig to hide their treasures and then dig again to retrieve them, often forgetting where many were buried!
Foraging for Grubs and Insects
Squirrels are omnivores and enjoy a varied diet. Grubs, earthworms, and other soil-dwelling insects are a tasty protein source. They will aggressively dig in areas where they detect these snacks, particularly after rain when the soil is softer.
Nesting and Burrowing
While less common on manicured lawns, some squirrels may attempt to create shallow burrows or nesting sites, especially if they feel threatened or are looking for shelter from extreme weather.
Natural Solutions for Deterring Squirrels
Many gardeners and homeowners prefer natural repellents and methods that are safe for pets and children. These approaches focus on making your lawn unappealing to squirrels.
Making Your Lawn Less Appealing
Squirrels are creatures of habit and convenience. If your lawn becomes an inconvenience, they’ll likely move on.
Strong Scents
Squirrels have a keen sense of smell and dislike certain strong odors. Incorporating these into your pest control strategy can be very effective.
- Cayenne Pepper/Chili Powder: Sprinkle liberally around areas where squirrels are digging. Reapply after rain or watering.
- Garlic: Crushed garlic cloves or garlic powder can be scattered. You can also plant garlic around your garden beds.
- Mint: Planting mint (especially peppermint) around the perimeter of your lawn or in patches can deter them. They dislike the strong aroma.
- Coffee Grounds: Used coffee grounds, when sprinkled around, can be an effective rodent deterrent.
- Vinegar: Diluted vinegar can be sprayed around the edges of the lawn. Be cautious as strong concentrations can harm grass.
Unpleasant Textures
Squirrels prefer soft, easy-to-dig soil. Altering the texture can make them think twice.
- Gravel or Small Stones: Scattering a layer of gravel or small, sharp stones on the surface of your lawn can make digging uncomfortable and difficult for them.
- Pine Cones: Spreading pine cones in garden beds or around young plants can create a prickly barrier.
Scent Granules and Sprays
There are many commercially available natural repellents that utilize predator urine (like fox or coyote) or essential oils (like peppermint or eucalyptus) to mimic the scent of predators, thus scaring squirrels away. These are generally considered safe for use in gardens and around homes.
Physical Barriers for Garden Protection
Creating physical barriers is a direct way to prevent squirrels from accessing your lawn and garden beds. These methods are excellent for garden protection.
Chicken Wire or Netting
- How it Works: Placing chicken wire or bird netting just below the surface of the soil in garden beds can prevent squirrels from digging where bulbs or seedlings are planted. For surface protection, you can lay it on top of the soil, anchoring it down.
- Application: Cut pieces to fit the area. For bulbs, place the wire about 1-2 inches below the soil surface. For general protection of planted areas, a layer on top, secured with landscape staples, works well. This is a key method for deterring digging.
Landscape Fabric
- How it Works: Durable landscape fabric can be laid down in garden beds before planting. It allows water and air to penetrate while making it difficult for squirrels to dig through.
- Application: Lay the fabric smoothly over the soil and secure it with staples. Cut small X-shaped openings for your plants to grow through.
Mulch Types
While mulch is generally good for lawn care, some types can be less appealing to squirrels.
- Coarse Mulch: Coarse mulches like wood chips or gravel are harder for squirrels to dig through compared to fine mulches.
- Pine Cones: As mentioned earlier, pine cones are excellent for creating a prickly deterrent.
Squirrel-Proofing Your Yard and Home
Squirrels are resourceful. Protecting specific areas is crucial for effective keeping squirrels out.
Protecting Bulbs and Seedlings
This is a prime target for digging squirrels.
Bulb Cages
- Description: These are wire cages that you plant with your bulbs. The bulbs grow through the wire, but the cage prevents squirrels from digging them up.
- Installation: Plant the cage with your bulbs, ensuring it’s buried securely.
Seed Starting Trays
- Description: Start seeds indoors in trays. Once seedlings are strong enough, transplant them into protected garden beds.
Securing Trash Cans
Squirrels are also attracted to the easy food source in trash cans.
- Secure Lids: Ensure all trash cans have tightly fitting lids.
- Bungee Cords/Clamps: Use bungee cords or specialized clamps to keep lids securely shut, especially on windy days.
Removing Food Sources
The most effective wildlife exclusion starts with removing what attracts them in the first place.
Bird Feeders
- Squirrel-Proof Feeders: Invest in feeders designed to deter squirrels, such as weight-activated feeders or those with baffles.
- Placement: Hang feeders away from trees or structures that squirrels can use to jump onto them. Consider placing feeders on poles with a squirrel baffle above and below.
- Spill Control: Clean up spilled birdseed regularly, as this is a major attractant.
Fallen Fruit and Nuts
- Regular Collection: Promptly collect any fallen fruit or nuts from trees in your yard.
Pet Food
- Indoor Feeding: Feed pets indoors or remove outdoor food bowls immediately after they have finished eating.
Mechanical Deterrents and Other Methods
When natural methods aren’t enough, mechanical deterrents can provide an extra layer of defense.
Decoy Predators
- Description: Plastic owls, snakes, or coyotes can sometimes startle squirrels and make them avoid an area.
- Effectiveness: Their effectiveness is often short-lived as squirrels quickly realize they are not real threats. Rotating their position and using reflective tape with them can increase their impact.
Ultrasonic Devices
- How they Work: These devices emit high-frequency sounds that are supposed to be irritating to squirrels and other small animals.
- Considerations: Research suggests their effectiveness can vary greatly, and they may not work for all squirrels or in all situations.
Motion-Activated Sprinklers
- Description: These devices detect movement and release a burst of water, startling the squirrel and making the area unpleasant.
- Benefits: This is a humane and effective way to scare them off. They also help water your lawn!
Trapping and Relocation (Use with Caution)
While trapping might seem like a direct solution, it’s often not the best approach for long-term pest control.
- Legality: Check local regulations regarding trapping and relocating wildlife. Many areas have strict rules.
- Humane Trapping: If you choose to trap, use live traps designed for squirrels.
- Relocation Challenges: Relocated squirrels often struggle to adapt to new territories and may not survive. It’s also important to note that the squirrels you remove may simply be replaced by others from the neighborhood. This is generally not considered safe squirrel removal unless done by a professional with knowledge of local ecosystems.
Understanding Squirrel Behavior for Effective Deterrence
Fathoming squirrel behavior is crucial for successful deterrence. They are intelligent and adaptable creatures.
Squirrel Intelligence
Squirrels can learn and adapt quickly. A deterrent that works today might be ignored tomorrow if they perceive no threat. This means you may need to rotate methods or combine them for sustained garden protection.
Seasonal Patterns
Squirrel activity often increases in spring and fall. Spring is when they are nesting and foraging for young, and fall is when they are busy burying nuts for winter. Being extra vigilant during these times can help.
What Attracts Them Most
- Easy Food Access: Bird feeders, fallen fruit, and accessible garbage are top attractants.
- Soft Soil: Newly planted areas, freshly tilled garden beds, and aerated lawns are perfect for digging.
- Shelter: Dense shrubs or undisturbed areas can provide them with a sense of security.
Long-Term Strategies for a Squirrel-Free Lawn
Keeping squirrels out is an ongoing process, not a one-time fix.
Consistent Application of Deterrents
Natural repellents, like cayenne pepper or garlic, need regular reapplication, especially after rain or watering, to remain effective.
Diversifying Your Approach
Don’t rely on a single method. Combining scent-based repellents with physical barriers and food source removal will yield the best results. This multi-pronged approach is key to deterring digging.
Maintaining a Healthy Lawn
A healthy, dense lawn is naturally more resistant to digging.
- Aeration and Dethatching: While good for lawn care, do these activities strategically. Squirrels might be attracted to the loosened soil initially.
- Proper Watering and Fertilizing: A well-maintained lawn is less likely to have insect pests that attract squirrels.
When to Call a Professional
If you’ve tried multiple methods and are still struggling with a significant squirrel problem, it might be time to seek professional help.
Professional Pest Control Services
- Expertise: Professionals have access to more potent rodent deterrents and humane safe squirrel removal techniques.
- Assessment: They can assess your specific situation and recommend the most effective long-term solutions for wildlife exclusion.

Frequently Asked Questions (FAQ)
Will planting marigolds stop squirrels from digging?
Marigolds are often cited as a natural deterrent for various garden pests, including some burrowing animals, due to their scent. While some gardeners find them helpful, their effectiveness against squirrels can be inconsistent. Squirrels may avoid areas with marigolds, but it’s not a foolproof method for keeping squirrels out of your entire lawn. It’s best used as part of a multi-pronged strategy.
Can I use human hair to deter squirrels?
Yes, human hair, especially from pets like dogs or cats, can act as a rodent deterrent because it carries the scent of a predator. Scattering hair clippings around your garden beds can signal danger to squirrels. You’ll need to replenish it periodically as it breaks down.
What about mothballs? Are they safe and effective?
Mothballs contain naphthalene or paradichlorobenzene, which are toxic chemicals. While they can deter squirrels due to their strong smell, they are also harmful to pets, children, and beneficial soil organisms. Their use is often discouraged and may be illegal in some areas for outdoor use. It’s better to stick to safer, more natural rodent deterrents.
How can I stop squirrels from digging up my flower bulbs?
To prevent squirrels from digging up flower bulbs, consider planting them inside wire cages or using chicken wire placed just below the soil surface. You can also try coating bulbs with cayenne pepper or a commercially available repellent before planting. A thick layer of coarse mulch or gravel on top of the soil after planting can also make digging more difficult.
Are there any humane ways to remove squirrels from my yard?
Humane methods for safe squirrel removal primarily focus on deterrence. This includes removing attractants like bird feeders and fallen fruit, using scent-based natural repellents, and installing physical barriers. If trapping is necessary, live traps are the most humane option, but remember that relocation is often difficult for the squirrels and may not solve the problem permanently.
By implementing a combination of these strategies, you can significantly reduce and eventually stop squirrels from digging up your lawn, ensuring a healthier and more attractive yard.
