Why Squirrels Dig and What They’re After

Before we can effectively stop squirrels from digging, it’s helpful to grasp why they do it. Squirrels are driven by instinct and need, and their digging behavior stems from several key motivations:

  • Food Storage (Caching): This is the primary reason. Squirrels, especially during autumn, bury nuts, seeds, and other food items to store for later consumption. They have a remarkable memory for their cache locations, but they also dig up the caches of other squirrels or even forgotten caches from previous seasons. This is why you often see them “re-digging” in areas.
  • Foraging: They’re always on the lookout for food, and this includes actively searching for buried nuts and seeds. They use their keen sense of smell to locate these buried treasures.
  • Creating Burrows and Nests: While less common in established yards for primary nesting, squirrels will dig to create temporary resting spots, escape predators, or prepare areas for winter nesting, especially if they can’t access more suitable tree cavities.
  • Water and Moisture: In dry periods, squirrels might dig to reach cooler, moister soil.
  • Play and Curiosity: Young squirrels, in particular, are naturally curious and may dig out of playfulness.

The Impact of Squirrel Digging on Your Yard

The consequences of squirrel digging can be frustrating for any gardener or homeowner:

  • Destroyed Plantings: Bulbs can be unearthed and eaten or damaged before they even sprout. Young seedlings are easily uprooted and can die.
  • Ugly Holes: Bare patches and unsightly holes mar the appearance of lawns and garden beds.
  • Damage to Infrastructure: In some cases, persistent digging can undermine shallow landscaping elements or even get close to foundations if not addressed.
  • Competition with Wildlife: While not a direct homeowner concern, their digging can impact other small ground-dwelling creatures.

Effective Strategies to Deter Squirrels from Digging

Stopping squirrels from digging requires a multi-pronged approach. The goal is to make your yard less appealing to them as a food storage or foraging ground.

1. Natural Squirrel Deterrents: Making Your Yard Unpleasant

Nature offers several scent and taste deterrents that squirrels find unpleasant. Applying these regularly can significantly reduce their digging activity.

Spicy Scents

Squirrels have sensitive noses, and certain strong scents can overwhelm them.

  • Cayenne Pepper: A classic natural squirrel deterrent. Sprinkle cayenne pepper liberally around flowerbeds, vegetable gardens, and areas where you see digging. Reapply after rain or watering.
  • Chili Powder/Flakes: Similar to cayenne pepper, these can be effective.
  • Garlic: The strong smell of garlic can deter them. You can use garlic powder or even crushed garlic cloves scattered around.
  • Peppermint Oil: Soak cotton balls in peppermint oil and place them strategically in affected areas. The strong scent is a powerful squirrel repellent.

Bitter Tastes

Some substances have a bitter taste that squirrels dislike.

  • Bitter Apple Spray: Available commercially, this is a safe and non-toxic spray that tastes unpleasant to many animals.
  • Soap: Many gardeners report that scattering bar soap shavings (especially strong-smelling ones like Irish Spring) can deter squirrels due to the scent and texture.

Other Natural Deterrents

  • Coffee Grounds: Used coffee grounds, while beneficial to some plants, can also act as a mild deterrent due to their scent and texture.
  • Cinnamon: The strong aroma of cinnamon can be a turn-off for squirrels.

Important Note on Natural Deterrents: These methods require consistent reapplication, especially after rain or irrigation. They are most effective when used as part of a broader strategy.

2. Modifying the Habitat: Removing Attractions

Making your yard less attractive to squirrels is a fundamental step in preventing digging.

Secure Your Bird Feeders

Bird feeders are a major draw for squirrels, not just for the seeds but also for the ease of access and potential for caching.

  • Squirrel-Proof Feeders: Invest in feeders designed to deter squirrels. These often have weight-activated perches that close off seed ports when a heavier animal like a squirrel lands on them.
  • Baffles: Install cone-shaped or dome-shaped baffles above or below feeders to prevent squirrels from climbing or reaching them.
  • Placement: Hang feeders at least 10-15 feet away from trees, fences, or other structures that squirrels can use as launching pads.
  • Cleanliness: Regularly clean up spilled seed around feeders, as this is a prime target for foraging squirrels. This is crucial for bird feeder protection.

Manage Food Sources

  • Harvest Ripe Fruit: Don’t leave fallen fruit from trees (apples, pears, cherries) on the ground. Squirrels love these and will dig to bury or access them.
  • Secure Trash Cans: Ensure your trash cans have tight-fitting lids. Squirrels are opportunistic feeders and will rummage through garbage.
  • Pet Food: Avoid leaving pet food outdoors.

Remove Potential Shelter and Hiding Spots

  • Trim Overhanging Branches: Reduce easy access routes to your yard and roof.
  • Clear Debris: Remove piles of leaves, woodpiles, or dense brush where squirrels might hide or nest.

3. Physical Barriers: Creating Impassable Defenses

Physical barriers are one of the most reliable ways to keep squirrels out of specific areas.

Protecting Individual Plants and Bulbs

  • Chicken Wire or Hardware Cloth: Before planting bulbs, place a layer of chicken wire or hardware cloth (1/2-inch mesh) just below the soil surface. You can also place it on top of the soil around vulnerable plants, securing it with landscape staples. This allows plants to grow through while blocking digging. This is excellent for garden protection.
  • Plant Cages: For individual plants, consider using wire cages that enclose the base of the plant.
  • Gravel Mulch: A thick layer of gravel or coarse mulch around plants can make digging difficult and uncomfortable for squirrels.
  • Row Covers: For vegetable gardens, use lightweight row covers secured firmly to the ground.

Protecting Entire Garden Beds

  • Fencing: A low fence around garden beds can be effective, but it needs to be the right type. Squirrels are agile climbers.
    • Height: At least 2-3 feet tall.
    • Material: Sturdy wire mesh (1-inch or less) is best.
    • Buried Base: Bury the bottom edge of the fence at least 6 inches into the ground to prevent burrowing underneath.
    • Overhang: Consider an outward-facing, 6-12 inch overhang at the top of the fence to deter climbing.

4. Scare Tactics: Visual and Auditory Deterrents

Squirrels are cautious creatures, and novel or startling stimuli can make them wary of your yard.

Visual Deterrents

  • Shiny Objects: Mylar tape, old CDs, or aluminum foil strips hung from branches or stakes can reflect light and movement, startling squirrels.
  • Predator Decoys: While less reliable long-term, placing realistic owl or hawk decoys can sometimes work initially. Move them frequently to prevent squirrels from realizing they are not a threat.
  • Pinwheels and Wind Chimes: The movement and noise can be unsettling for them.

Auditory Deterrents

  • Ultrasonic Devices: These devices emit high-frequency sounds that are supposed to be unpleasant to rodents and other pests, including squirrels. Their effectiveness can vary, and some people report that squirrels get used to them over time.
  • Noise Makers: Occasional loud noises, like banging pots and pans when you see a squirrel, can startle them away. However, this is a short-term solution.

5. Repellent Sprays: Commercial and DIY Options

Beyond natural scents, several commercial squirrel repellent sprays are available. These often contain ingredients like:

  • Predator Urine: The scent of coyote or fox urine can trigger an instinctual fear response in squirrels.
  • Essential Oils: Many commercially available repellents use a blend of essential oils like peppermint, rosemary, or clove.
  • Ammonia: Some older, harsher repellents used ammonia, but these can be harmful to plants and are generally less recommended for yard use.

DIY Repellent Spray:
You can create your own by mixing:
* 1 quart water
* 1 tablespoon cayenne pepper
* 1 tablespoon garlic powder
* A few drops of liquid dish soap (to help it stick)
Shake well and spray on affected areas. Reapply frequently.

6. Humane Squirrel Control Methods

When other methods fail, and you need to address an existing population, humane squirrel control is the most ethical approach.

  • Live Trapping: If squirrels are causing significant damage, live traps can be used.
    • Baiting: Use attractive baits like peanut butter, sunflower seeds, or apple slices.
    • Placement: Place traps in areas where squirrels are active, often near their entry points or digging sites.
    • Relocation: Check traps frequently. If you catch a squirrel, relocate it far from your property (check local regulations for relocation laws, as it’s often illegal or ineffective if done improperly). Squirrels are territorial, and moving them can be detrimental to their survival. Relocation can also simply move the problem to someone else’s yard.
  • Exclusion: If squirrels are entering your attic or other structures, seal entry points once you’re sure they are out. This might involve waiting until they leave to forage or using one-way doors.

7. Addressing Existing Damage and Prevention

  • Repair Holes: Fill in any holes squirrels have dug promptly. This discourages them from returning to the same spots and helps your lawn or garden recover.
  • Rake and Clear: Keep your yard clean. Fallen leaves, nuts, and debris provide cover and potential food sources, making your yard more attractive.
  • Water Your Lawn: A well-watered, healthy lawn is less appealing for digging compared to dry, compacted soil.

Squirrel Proofing Your Yard: A Comprehensive Checklist

To effectively deter squirrels and prevent digging, consider this checklist:

  • Eliminate Food Sources:
    • Secure bird feeders (baffles, squirrel-proof feeders).
    • Clean up fallen fruit and nuts.
    • Secure trash cans.
    • Do not leave pet food outdoors.
  • Make Plants Unappealing:
    • Apply natural squirrel repellent (cayenne, peppermint).
    • Use physical barriers (chicken wire, cages).
    • Apply commercial repellents or DIY sprays.
    • Use gravel or coarse mulch.
  • Modify the Environment:
    • Trim overhanging branches.
    • Remove debris and hiding spots.
    • Ensure proper fencing with buried bases and overhangs.
  • Scare Tactics:
    • Use shiny objects or pinwheels.
    • Consider ultrasonic devices (with caution).
  • Maintenance:
    • Repair dug holes immediately.
    • Keep the yard clean and tidy.

Squirrels and Your Vegetable Garden

Vegetable gardens are prime targets for squirrels due to the abundance of tasty offerings.

Key Strategies for Vegetable Gardens

  • Raised Beds: Planting in raised beds can make them slightly less accessible.
  • Netting and Row Covers: This is crucial. Cover plants with fine-mesh netting or floating row covers, securing the edges firmly to the ground with stakes or rocks. This provides a physical barrier against both digging and nibbling.
  • Companion Planting: Some plants are said to deter squirrels with their scent, such as marigolds, garlic, and onions. While not foolproof, they can be a complementary strategy.
  • Repellent Application: Regularly spray vegetable plants and the surrounding soil with a natural squirrel deterrent like cayenne pepper mixed with water and a little soap. Be sure to wash vegetables thoroughly before eating.

Frequently Asked Questions (FAQ)

Q1: Will cayenne pepper actually stop squirrels from digging?
A1: Yes, cayenne pepper is a well-known natural squirrel deterrent. Squirrels dislike the spicy sensation it causes when they come into contact with it, discouraging them from digging in treated areas. However, it needs to be reapplied regularly, especially after rain.

A2: While mothballs (naphthalene) are sometimes suggested, they are not recommended for garden use. They can be toxic to plants, pets, and beneficial insects, and their effectiveness against squirrels is often inconsistent. Safer, more targeted methods are preferable for yard pest control.

Q3: How long does it take to see results from squirrel deterrents?
A3: Results can vary depending on the method and the squirrel population in your area. Natural deterrents and scare tactics may show results within a few days to a week of consistent application. Physical barriers offer immediate protection.

Q4: What is the best way to keep squirrels out of my flower bulbs?
A4: The most effective way to prevent digging around bulbs is to use physical barriers. Plant bulbs with a layer of chicken wire or hardware cloth buried just beneath the soil surface, or place cages around newly planted bulbs. You can also apply squirrel repellent sprays to the soil surface.

Q5: Are ultrasonic squirrel repellers effective?
A5: The effectiveness of ultrasonic repellers is debated. Some users report success, while others find squirrels become accustomed to the sound. They are generally considered a secondary or complementary method rather than a primary solution for humane squirrel control.

Q6: What should I do if I see squirrels digging in my newly seeded lawn?
A6: If squirrels are digging in your new lawn, immediately cover the seeded areas with a light layer of straw or peat moss, and then a layer of chicken wire or bird netting secured with landscape staples. This will protect the seeds while allowing grass to sprout. You can also sprinkle a squirrel repellent on the surface.

Q7: My bird feeder is constantly being raided. How can I achieve bird feeder protection?
A7: To achieve effective bird feeder protection, install squirrel baffles on poles or hanging wires, use weight-activated squirrel-proof feeders, and ensure feeders are placed at least 10-15 feet away from jumping-off points like trees and fences. Keep the area around the feeder clean of spilled seed.

By implementing these strategies, you can effectively deter squirrels, prevent digging, and reclaim your yard for your enjoyment. A combination of making your yard less attractive, using physical barriers, and consistent application of repellents is the key to successful yard pest control and garden protection.
