Why Are Squirrels Digging Up My Lawn: Protect Your Yard

by

Squirrels dig up lawns for several reasons, primarily to hide and retrieve food, construct nests, and sometimes out of sheer curiosity. If you’re dealing with this squirrel digging issue, rest assured there are ways to manage this lawn damage and deter future squirrel activity.

Fathoming the Motives Behind Squirrel Digging

Squirrels are incredibly industrious creatures, and their digging habits are deeply rooted in their survival instincts. Observing squirrel digging isn’t just a quaint backyard spectacle; it’s a window into their world. When you see those tell-tale mounds of disturbed earth, it’s not random vandalism. It’s the result of very specific behaviors driven by necessity and instinct.

The Stash and Retrieve Strategy

The most common reason for squirrel digging is their meticulous habit of caching (hiding) food for leaner times. Squirrels are hoarders by nature. During peak seasons, when nuts, seeds, and acorns are abundant, they collect these treasures and bury them strategically throughout your yard. They possess an impressive memory, but not a perfect one. This means they’ll also spend considerable time digging up their buried food stores. This constant burying and unearthing creates the familiar lawn damage you’re observing. Each hole is a potential pantry or a retrieval mission.

Commonly Stored Foods:

  • Acorns
  • Walnuts
  • Hazelnuts
  • Sunflower seeds
  • Peanuts (especially if you feed them)
  • Other seeds and bulbs

Nest Building and Burrowing Habits

While squirrels are well-known for nesting in trees, some species, particularly ground squirrels, also dig burrows for shelter and to raise their young. These burrows can be extensive, involving multiple entrances and chambers. This type of squirrel activity can lead to more significant lawn damage, especially if they decide your garden bed or a less-trafficked corner of your yard is the perfect spot for their home. This is where the line between squirrel digging and other burrowing animals can sometimes blur, though squirrels are generally more visible and active during the day.

Curiosity and Playfulness

Young squirrels, in particular, can be quite curious and playful. They might dig shallow holes simply to explore, chase each other, or investigate interesting smells. While this squirrel activity might not cause extensive damage, it adds to the overall disruption of your lawn.

Deciphering the Signs of Squirrel Damage

Recognizing the specific signs of squirrel digging is key to effective yard pest control. The patterns of disturbance can tell you a lot about what the squirrels are up to.

Distinctive Digging Patterns

  • Small, scattered holes: These are typically from squirrels burying or retrieving individual nuts or seeds. The holes are usually no deeper than a few inches.
  • Larger, more organized excavations: This could indicate a squirrel attempting to create a more permanent burrow or nest. These might be found near structures, under bushes, or in undisturbed areas of your yard.
  • Disturbed mulch or garden beds: Squirrels often find soft soil ideal for digging. Garden beds, especially those with freshly tilled soil or bulbs, are prime targets. This contributes to gardening problems.
  • Uprooted plants: In their search for food or nesting material, squirrels might dig around plant roots, sometimes even pulling out small plants.

What Squirrels Are Looking For

  • Bulbs: Tulip, daffodil, and crocus bulbs are a favorite treat for squirrels. They can detect them underground, leading to targeted digging in flower beds.
  • Seeds: Any seeds left from bird feeders or dropped by plants in your yard will be a target.
  • Insects: While not their primary food, squirrels will sometimes dig to find grubs or other insects.
  • Comfort: Soft, loose soil is appealing for digging and nesting.

Addressing Lawn Damage: Practical Solutions

Once you’ve identified the cause of your lawn damage, it’s time to implement strategies for pest removal and animal deterrence. The goal is to make your yard less appealing to squirrels without harming them.

Squirrel-Proofing Your Yard

Making your yard less attractive is often the most effective long-term solution. This involves a multi-pronged approach to animal deterrence.

Managing Food Sources

  • Secure Bird Feeders: If you feed birds, consider squirrel-proof feeders. Alternatively, place feeders in locations squirrels find difficult to access, such as on a pole with a baffle. Clean up spilled seed regularly, as this is a major attractant.
  • Harvest Fallen Fruit: If you have fruit trees, collect fallen fruit promptly. Squirrels will happily feast on it and then start digging around the base of the trees.
  • Secure Compost Bins: Ensure your compost bins are fully sealed to prevent squirrels from accessing food scraps.
  • Remove Pet Food: Never leave pet food outdoors, as it’s a readily available food source for many wildlife, including squirrels.

Protecting Your Garden

  • Guard Bulbs: When planting bulbs, consider using chicken wire or hardware cloth just below the soil surface. You can also try deterrent sprays or sprinkle cayenne pepper around newly planted bulbs.
  • Use Barriers: For vulnerable plants, consider using netting or cages to protect them from digging.
  • Mulch Wisely: While mulch is good for the soil, squirrels can dig through it easily. Consider using coarser mulches like gravel or pine cones in areas where digging is a problem.

Natural Deterrents and Repellents

Several natural methods can help discourage squirrel activity without resorting to harsh chemicals.

Scent-Based Deterrents

Squirrels have sensitive noses. Certain strong scents can drive them away.

  • Cayenne Pepper/Red Pepper Flakes: Sprinkle generously around plants, bulbs, and areas where digging occurs. Reapply after rain.
  • Garlic and Onion: Chopped garlic or onion can be scattered, or you can use garlic spray.
  • Peppermint Oil: Mix a few drops of peppermint oil with water and spray it around your yard.
  • Soaked Cotton Balls: Soak cotton balls in these scents and place them strategically around the yard.

Taste-Based Deterrents

These work by making the squirrels have an unpleasant experience when they try to eat something.

  • Bittersweet Spray: Available commercially or can be made at home with bitter apple or similar non-toxic ingredients. Apply to plants or bulbs.
  • Castor Oil: Mixing castor oil with water can create a barrier that squirrels dislike the taste of.

Sound and Motion Deterrents

  • Ultrasonic Devices: These emit high-frequency sounds that are supposed to deter rodents and other small animals. Their effectiveness can vary.
  • Motion-Activated Sprinklers: These devices detect movement and spray a burst of water, startling squirrels and encouraging them to leave.

Physical Barriers

Physical barriers are a direct way to prevent squirrel digging and protect your lawn.

  • Hardware Cloth/Chicken Wire: Burying this material a few inches below the surface around garden beds or vulnerable plants can stop burrowing. You can also lay it on top of bulbs before covering with soil.
  • Netting: Lightweight netting can be draped over plants or garden areas. Ensure it’s secured so squirrels don’t get tangled.

Advanced Yard Pest Control Methods

When natural deterrents aren’t enough, you might need to consider more direct pest removal or exclusion methods.

Exclusion Tactics

  • Fencing: While a full fence around your entire yard can be expensive and might not be practical, you can use fencing to protect specific garden areas. Ensure the fence is buried at least 6 inches deep and extends at least 2 feet above ground to prevent climbing.
  • Tree Guards: If squirrels are accessing your yard via trees, consider placing metal baffles or guards around tree trunks to prevent them from climbing.

Live Trapping and Relocation

Live trapping is an option for particularly problematic squirrels. However, it’s crucial to be aware of local regulations regarding wildlife trapping and relocation.

  • Trap Placement: Place traps in areas of high squirrel activity, near their suspected entry points or favorite digging spots.
  • Baiting: Use peanut butter, nuts, or seeds as bait.
  • Relocation: If you choose to relocate squirrels, do so far from your home (at least 5-10 miles) in a suitable habitat. However, relocation can be stressful for the animal and may not solve the problem long-term if the area you move them to is also attractive to other squirrels.

Important Note: Rodent damage from squirrels can sometimes extend to electrical wires if they are nesting in attics or chewing on outdoor cables. If you suspect this, it’s best to consult a professional.

When to Call the Professionals

Sometimes, despite your best efforts, the squirrel digging and lawn damage persist. This is when it’s time to consider professional help.

Identifying Signs You Need Professional Help

  • Extensive Burrowing: If you notice large holes or extensive tunnel systems, it might indicate a larger squirrel population or a more established presence that requires expert pest removal.
  • Damage to Structures: If squirrels are gnawing on your house’s siding, eaves, or entering your attic, this is a serious concern that requires professional attention to prevent further rodent damage.
  • Persistent Activity: If your deterrents and exclusion methods aren’t working after consistent application, a professional can offer more advanced solutions.

Protecting Your Green Space: A Comprehensive Approach

Effectively managing squirrel digging requires patience and a consistent strategy. By fathoming their motivations and employing a combination of deterrents, barriers, and good yard management, you can significantly reduce the lawn damage and enjoy your yard again.

Maintaining a Healthy Lawn

A well-maintained lawn is generally more resilient to squirrel activity.

  • Proper Mowing and Watering: Healthy grass is denser and can recover more quickly from minor disturbances.
  • Aeration and Dethatching: Regular lawn care practices can improve soil health and make it less appealing for digging.

Seasonal Considerations

Squirrel behavior often changes with the seasons.

  • Spring: This is a prime time for nest building and raising young, leading to increased digging.
  • Fall: This is when squirrels are most actively burying nuts for winter, resulting in widespread digging.

Collaborative Efforts

If you live in a neighborhood with a significant squirrel population, sometimes collective action can be more effective. Discussing yard pest control strategies with neighbors might lead to broader deterrent efforts.

Frequently Asked Questions (FAQ)

Q1: Are squirrels harmful to my lawn?

Yes, squirrels can cause lawn damage by digging holes, uprooting plants, and potentially damaging bulbs when searching for food. Their burrowing can also disrupt the soil structure.

Q2: Can I use poison to get rid of squirrels?

It is generally not recommended to use poison for pest removal of squirrels. Poisons can be harmful to other wildlife, pets, and even humans. They are also not always effective and can cause suffering to the animal. Humane deterrents and exclusion methods are preferred.

Q3: How do I stop squirrels from digging up my flower bulbs?

To protect your bulbs from squirrel digging, you can plant them deeper, cover them with chicken wire or hardware cloth before the soil, or apply natural deterrents like cayenne pepper or predator urine around the planting area.

Q4: What is the best way to deter squirrels from my yard?

The best way to deter squirrels involves a combination of removing attractants (food sources), using scent and taste deterrents, and installing physical barriers around vulnerable areas. Consistent effort is key.

Q5: Why are squirrels burying nuts in my lawn?

Squirrels bury nuts and other food items as a way to store them for later consumption. Your lawn, with its loose soil and potentially abundant food sources (like dropped seeds from bird feeders), is an ideal location for their caching behavior. This constant burying and retrieval is a major cause of squirrel digging.

Q6: Are there specific times of year when squirrels dig more?

Yes, squirrel activity involving digging tends to be higher in the spring (for nesting) and especially in the fall (for storing food for winter). This is when you’re most likely to see significant lawn damage from their efforts.

By implementing these strategies, you can take proactive steps to protect your lawn from the persistent squirrel digging and ensure your yard remains a beautiful and enjoyable space.
