Why Do Squirrels Dig in Lawns?

Before we explore how to stop them, it’s helpful to understand why squirrels are so fond of your lawn. Their digging isn’t malicious; it’s driven by instinct and necessity.

• Food Storage (Cacheing): Squirrels are hoarders. They bury nuts, seeds, and other food items for later consumption. Your lawn, with its soft soil, is an ideal spot for this. They have an incredible memory for their caches, but not all are recovered, leading to more digging.
• Foraging: Squirrels also dig to unearth food that might be just beneath the surface, like insect larvae, grubs, or even bulbs from your flowerbeds.
• Nesting and Burrowing: While less common for typical lawn digging, some squirrel species may dig shallow burrows or expand existing ones for shelter, especially during harsh weather.
• Play and Exploration: Young squirrels, in particular, might dig simply out of curiosity or as part of their playful exploration of their territory.

5 Effective Squirrel Deterrents for Your Lawn

Here are five proven methods to discourage squirrels from turning your lawn into their personal pantry and playground.

1. Natural Squirrel Repellents: Harnessing Nature’s Signals

One of the most humane and environmentally friendly ways to deter squirrels is by using natural squirrel repellents. These methods work by making your lawn unappealing to squirrels through scent or taste.

Spicy Scents

Squirrels have sensitive noses, and certain strong smells can be quite off-putting.

• Capsaicin-based Sprays: The active compound in chili peppers, capsaicin, is a potent irritant to squirrels. You can create a homemade squirrel repellent by mixing water with cayenne pepper or hot sauce.
  • DIY Recipe:
    • 1 tablespoon of cayenne pepper or hot sauce
    • 1 quart of water
    • A few drops of liquid dish soap (to help the spray adhere)
  • Application: Mix well and spray generously on areas where squirrels are digging. Reapply after rain or watering, as the repellent can wash away. Be cautious when handling chili peppers and avoid spraying directly on plants that you don’t want to be seasoned.
• Peppermint Oil: Squirrels generally dislike the strong scent of peppermint.
  • Method: Soak cotton balls in peppermint essential oil and place them around your lawn, especially in affected areas. Alternatively, you can create a spray by mixing a few drops of peppermint oil with water.
• Coffee Grounds: Many gardeners swear by used coffee grounds. The smell and texture can deter squirrels. Sprinkle them generously around your lawn and garden beds. This also has the added benefit of enriching your soil.
• Garlic and Onion: The strong odors of garlic and onions are also known to repel squirrels. You can chop up garlic cloves or onion skins and scatter them around your lawn.

Unpleasant Tastes

Some substances, while harmless, taste bad to squirrels and will discourage them from nibbling on plants or digging.

• Castor Oil: This is a classic natural squirrel repellent. Squirrels dislike the taste and texture of castor oil.
  • Application: Mix castor oil with water and a bit of dish soap to create an emulsion. Spray this mixture onto the soil. Be careful not to overuse it, as too much castor oil can harm beneficial soil organisms.
• Bitter Apple Spray: Available commercially, bitter apple sprays are formulated to taste unpleasant to animals without causing harm. They are often used on furniture to deter chewing, but can also be applied to lawns and plants.

Important Note: When using homemade squirrel repellent or any new product, always test it on a small, inconspicuous area of your lawn first to ensure it doesn’t harm your grass. Reapplication is key, especially after rainfall, to maintain effectiveness.

2. Physical Barriers: Blocking Access and Burrowing

Physical barriers are a direct and effective way to prevent squirrels digging and protect specific areas of your lawn or garden.

Exclusion Netting and Cages

For high-value areas like newly planted bulbs or vegetable gardens, physical exclusion is a foolproof method.

• Wire Mesh (Hardware Cloth): This sturdy mesh, typically with openings of 1/2 inch or less, is excellent for creating barriers. You can:
  • Lay it over planting beds: Secure the mesh to the ground with garden stakes or landscape staples. You can lift it to weed or harvest and then replace it.
  • Bury it around garden beds: Burying the edges of the mesh a few inches into the ground creates a subterranean barrier, preventing squirrels from digging underneath.
  • Create individual cages: For delicate plants or bulbs, construct small cages or cloches out of hardware cloth to cover them completely.
• Garden Netting: Lightweight netting can be draped over plants, but it’s less effective against determined diggers as squirrels can sometimes push through it or burrow around it. It’s best used in conjunction with other methods.

Mulch and Ground Cover

The type of mulch you use can also play a role in deterring squirrels.

• Gravel or Crushed Shells: Squirrels often dislike walking on or digging through coarse materials like gravel, small stones, or crushed shells. Spreading a layer of these materials around vulnerable plants can make your lawn less inviting.
• Pine Cones: The spiky texture of pine cones can be a deterrent. Scatter them in garden beds.
• Dense Ground Cover: Planting dense, low-growing ground cover plants can reduce the open, accessible soil areas that squirrels prefer for digging.

Edging and Borders

Creating physical boundaries can make it more difficult for squirrels to access certain areas.

• Metal or Plastic Edging: Install sturdy edging around garden beds. Ensure it’s deep enough to prevent burrowing underneath.

3. Habitat Modification: Making Your Yard Less Attractive

squirrels are looking for food, water, and shelter. By removing or reducing these attractants, you can make your yard less appealing to them.

Secure Food Sources

• Bird Feeders: Bird feeders are a squirrel’s paradise. If squirrels are a major problem, consider squirrel-proof feeders or temporarily removing feeders altogether. If you keep them up, use baffles to prevent squirrels from climbing poles or accessing feeders. Clean up spilled seed regularly, as this is a major attractant.
• Fallen Fruit and Nuts: Regularly collect fallen fruit from trees and nuts from the ground. These are prime food sources for squirrels.
• Pet Food: Do not leave pet food outdoors. Store it in sealed containers.

Remove Water Sources

While less common, squirrels do need water. Ensure there are no stagnant water sources, like clogged gutters or leaky hoses, that might be attracting them.

Trim Overhanging Branches

Squirrels are agile climbers and can easily jump from trees onto your roof or into your yard. Trim back any tree branches that overhang your house or lawn, especially those near your garden. This can make access more difficult.

Secure Trash Cans

Ensure your trash cans have tight-fitting lids. Squirrels are adept at knocking over unsecured bins to get to discarded food scraps.

4. Introduce Natural Predators and Repellents (Scent and Sound)

While you might not want a fox or hawk in your yard, you can mimic their presence or introduce scents that naturally deter squirrels.

Scent-Based Deterrents (Beyond DIY)

Several commercially available squirrel deterrents utilize natural ingredients that squirrels find unpleasant. These often include essential oils (like peppermint, citronella, castor oil) or predator urine (like fox or coyote urine).

• Granular Repellents: These are typically made from dried organic matter treated with repellent scents. They can be scattered around the lawn and garden.
• Liquid Sprays: Similar to the DIY versions, these use concentrated repellent scents. Always follow product instructions carefully.

Ultrasonic Devices

These electronic devices emit high-frequency sounds that are inaudible to humans but are supposed to irritate and repel squirrels and other pests.

• Effectiveness: The effectiveness of ultrasonic devices is debated. Some users report success, while others find they have little to no impact. Squirrels may also become accustomed to the sounds over time. If you consider this option, choose a reputable brand and position the devices strategically.

Predator Decoys

The idea here is to create a visual deterrent.

• Owl or Hawk Decoys: Placing realistic-looking owl or hawk decoys around your lawn can sometimes startle squirrels. However, squirrels are intelligent and will quickly learn that the decoys are not a real threat, especially if they remain stationary. Moving the decoys regularly can increase their perceived effectiveness.

5. Companion Planting and Ground Cover Strategies

Certain plants can act as natural squirrel repellents, and changing your ground cover can make digging less appealing.

Plants Squirrels Dislike

Some plants have strong scents or tastes that squirrels tend to avoid. Incorporating these into your garden design can help create a natural barrier.

• Herbs: Mint, rosemary, lavender, and sage are fragrant herbs that squirrels generally do not favor.
• Alliums: Onions, garlic, chives, and leeks have strong odors that can deter squirrels.
• Marigolds: These cheerful flowers are often cited as a natural squirrel repellent due to their pungent scent.
• Coleus Canina (Scaredy Cat Plant): This plant has a strong, unpleasant odor that is said to repel cats, dogs, and squirrels.

Strategic Ground Cover

• Dense Grasses: A healthy, dense lawn with deep roots is harder for squirrels to dig into. Proper lawn care—including aeration, proper watering, and fertilization—can promote this density.
• Avoid Bare Soil: Minimize large areas of bare soil, which are prime targets for digging. Cover them with mulch, ground cover plants, or landscape fabric.

Addressing Existing Squirrel Damage

If squirrels have already caused damage, it’s important to repair it promptly.

• Filling Holes: Fill any holes dug by squirrels with soil and reseed or lay sod. This prevents further erosion and makes the area less inviting for more digging.
• Bulb Protection: If bulbs have been dug up, you can try replanting them after coating them with a repellent (like chili powder or a commercial repellent) or placing them in wire mesh cages.

Humane Squirrel Removal and Relocation

In cases of severe infestations or if other methods fail, you might consider humane squirrel removal.

• Trapping: Live traps can be used to capture squirrels. However, it’s crucial to know your local laws regarding trapping and relocating wildlife. Relocating squirrels is often controversial, as it can disrupt ecosystems and does not address the underlying attractants in your yard. It is also important to ensure that the trapped animal is cared for humanely.
• Professional Pest Control: For persistent problems, a professional pest control for squirrels service can offer tailored solutions and expertise in humane removal and exclusion. They can identify entry points and advise on comprehensive squirrel proofing yard strategies.
