Why Do Squirrels Dig in Your Lawn?
Before we can effectively stop squirrels from digging, it’s important to grasp why they do it. Their motivations are varied and often instinctual.
Burying and Foraging for Food
The most common reason squirrels dig is to bury and retrieve food. Acorns, nuts, and seeds are their primary diet, and they have an incredible memory for where they’ve stashed their treasures. They’ll create numerous small holes to bury individual items, often forgetting where some are, leading to continuous digging.
Nesting and Shelter
Squirrels also dig to create or expand their nests. They might dig into soft soil near tree roots or shrubs to establish a cozy den, especially during breeding season or when seeking refuge from harsh weather.
Finding Water
In dry periods, squirrels may dig in moist soil or near irrigation systems to access water.
Playing and Exploration
Young squirrels, in particular, might dig simply out of curiosity or as part of their play, exploring the textures and smells of the soil.
Identifying Squirrel Damage on Your Lawn
Recognizing the signs of squirrel activity is the first step in implementing effective lawn protection.
Small, Scattered Holes
This is the hallmark of squirrel digging. You’ll often see many small holes, typically a few inches deep, scattered across your lawn.
Disturbed Soil and Uprooted Plants
When squirrels are actively foraging or burying, they can dislodge small plants or unearth bulbs.
Mounds of Dirt
Sometimes, their digging activity can create small mounds of loose soil.
Visible Squirrels
The most obvious sign is, of course, seeing squirrels actively digging on your property.
Effective Squirrel Deterrents: A Multi-Pronged Approach
Stopping squirrels from digging requires a combination of methods that address their needs and make your lawn less appealing.
1. Make Your Lawn Less Appealing to Squirrels
The goal here is to remove attractants and create an environment that squirrels find undesirable.
Remove Food Sources
- Secure Trash Cans: Ensure your garbage cans have tight-fitting lids. Squirrels are opportunistic scavengers.
- Clean Up Fallen Fruit and Nuts: Regularly clear away any fallen fruits or nuts from trees in your yard. This eliminates a readily available food source.
- Bird Feeder Management: If you have bird feeders, consider squirrel-proof feeders or place them far from your lawn. Squirrels are notorious for raiding bird feeders and then digging around them to bury scattered seeds.
Eliminate Shelter and Hiding Spots
- Trim Overhanging Branches: Squirrels use tree branches to access your roof and lawn. Trimming branches that hang over your lawn can make access more difficult.
- Remove Debris: Clear away piles of leaves, brush, or wood that squirrels might use for shelter.
2. Physical Barriers for Lawn Protection
Physical barriers are an excellent way to keep squirrels out of specific areas.
Wire Mesh and Netting
- Around Garden Beds: Use chicken wire or hardware cloth to create a physical barrier around your vegetable gardens and flower beds. Bury the edges a few inches into the ground to prevent them from digging underneath.
- Protecting Bulbs: When planting bulbs, place a layer of chicken wire over the soil before covering it with more soil. This allows seedlings to push through but deters digging squirrels.
- Covering Seedlings: Young plants are particularly vulnerable. You can create small cages or covers from wire mesh to protect them.
Landscape Fabric and Mulch
- Dense Mulch: A thick layer of mulch, especially coarse or rough textures like wood chips or pine bark, can make digging more difficult for squirrels.
- Landscape Fabric: Laying down landscape fabric before adding mulch or soil can create an additional barrier.
3. Natural Repellents and Scent Deterrents
Squirrels have a keen sense of smell, and certain scents can deter them. Natural repellents are a great choice for amateur gardening and overall garden pest control.
Strong Scents Squirrels Dislike
- Peppermint Oil: Mix peppermint essential oil with water and spray it around the perimeter of your lawn and garden. Reapply after rain.
- Chili Pepper: Sprinkle cayenne pepper, red pepper flakes, or other hot peppers around areas squirrels frequent. The capsaicin irritates their noses and paws. Be cautious when applying this, as it can also irritate your skin.
- Garlic and Onion: Plant garlic and onions around your garden beds, or sprinkle garlic powder or chopped onions on the soil.
- Vinegar: Soak rags in white vinegar and place them strategically around your lawn. The strong smell can deter them.
- Coffee Grounds: Used coffee grounds, when sprinkled around plants, can act as a deterrent due to their texture and smell.
Commercial Natural Repellents
Many commercial repellents are available that use predator urine (like fox or coyote), castor oil, or essential oils as their active ingredients. Always follow the product instructions carefully.
Table: Natural Repellent Effectiveness
| Repellent Type | Active Ingredient Example(s) | Method of Application | Reapplication Frequency (after rain/wind) |
|---|---|---|---|
| Essential Oils | Peppermint, Eucalyptus | Spray diluted solution around affected areas. | Every few days or after rain |
| Capsaicin-Based | Chili Peppers, Cayenne | Sprinkle powder/flakes on soil or mix with water spray. | Every few days or after rain |
| Castor Oil | Castor Oil | Mix with water and spray, or soak rags and place. | Weekly or after rain |
| Predator Urine | Fox, Coyote | Spray or apply granules around the perimeter. | As per product instructions |
4. Habitat Modification to Discourage Digging Prevention
Making your landscape less inviting is a long-term strategy for digging prevention.
Choose Plants Wisely
- Avoid Squirrel Favorites: Some plants are more attractive to squirrels than others. Research which plants are less likely to be disturbed.
- Planting Depth: Ensure bulbs and young plants are planted at the correct depth. Deeper planting makes them harder for squirrels to unearth.
Soil Amendments
- Adding Grit: Mixing coarse sand or gravel into the soil can make it less appealing for digging.
5. Active Deterrents and Scare Tactics
These methods rely on startling or inconveniencing squirrels to make them avoid your lawn.
Motion-Activated Sprinklers
These devices detect movement and spray a burst of water, startling squirrels and discouraging them from returning. They are effective for covering larger areas.
Decoys and Reflective Materials
- Predator Decoys: While often temporary, placing owl or snake decoys strategically can sometimes deter squirrels, especially if moved regularly.
- Shiny Objects: Mylar tape or old CDs hung from branches can create flashes of light and movement that may startle squirrels.
Ultrasonic Devices
These devices emit high-frequency sounds that are inaudible to humans but are supposed to be unpleasant for rodents, including squirrels. Their effectiveness can be mixed, and some studies suggest animals may become accustomed to them.
6. Trapping and Relocation (Use with Caution)
Trapping squirrels is a more direct approach but comes with ethical and practical considerations.
- Live Traps: If you choose to trap, use live traps baited with nuts or seeds.
- Relocation Laws: Crucially, check your local laws and regulations regarding trapping and relocating wildlife. Many areas have restrictions on moving animals to prevent the spread of disease or to avoid introducing them into unfamiliar territories where they may not survive.
- Humane Practices: If you trap, check the trap frequently to minimize stress on the animal.
Squirrel Damage Control: Ongoing Lawn Care Tips
Consistent effort is key to successful lawn protection and preventing future squirrel damage.
- Regular Inspection: Keep an eye out for new digging activity and address it promptly.
- Reapply Repellents: Natural repellents need regular reapplication, especially after rain or heavy dew.
- Maintain Physical Barriers: Ensure any netting or wire mesh remains secure and intact.
- Prune Overgrown Vegetation: Regularly trim bushes and trees that provide easy access to your lawn.
Addressing Specific Squirrel Problems
How to Stop Squirrels from Digging Up Flower Bulbs
Squirrels are notorious for digging up freshly planted flower bulbs, mistaking them for nuts.
- Plant Deep: Ensure bulbs are planted at the recommended depth, or even a few inches deeper than usual.
- Chicken Wire Layer: Cover the planting area with chicken wire or hardware cloth before backfilling with soil. Cut holes for the bulbs to sprout.
- Natural Repellents: Sprinkle cayenne pepper or apply a castor oil-based repellent around the bulbs.
- Container Gardening: Consider planting bulbs in containers with secured mesh bottoms or tops to prevent access.
How to Stop Squirrels from Burying Nuts in Your Lawn
This is a constant battle as squirrels stockpile food for winter.
- Cleanliness: Keep your lawn free of fallen nuts and seeds from nearby trees or feeders.
- Discourage Nut Storage: Make your lawn unappealing by using scent deterrents. The constant disturbance of their burying efforts can be enough to make them move elsewhere.
- Dense Ground Cover: Encourage a thick, healthy turf that is less inviting for digging.
How to Stop Squirrels from Digging in Raised Garden Beds
Raised beds, with their rich soil, can be a prime target for squirrels.
- Wire Mesh Lids: Create removable wire mesh lids for your raised beds to keep squirrels out when you’re not actively gardening.
- Vertical Barriers: Extend wire mesh up the sides of the raised bed and outwards at an angle to make climbing over difficult.
- Row Covers: Use lightweight row covers over young plants, ensuring they are secured to the edges of the bed.
