Identifying the Culprit: Recognizing Ground Squirrels

Before you can effectively manage them, it’s crucial to identify that you’re dealing with ground squirrels. They are often mistaken for tree squirrels, but their habits and appearance differ.

Physical Characteristics

Size: Ground squirrels are typically smaller than tree squirrels, usually ranging from 6 to 12 inches in length, excluding their tail.
Tail: Their tails are generally shorter, bushier, and held more horizontally than the long, bushy, and often arched tails of tree squirrels.
Coloration: Coloration varies by species, but common ground squirrels often have brown or grayish-brown fur, sometimes with speckles or stripes.
Behavior: They are ground-dwelling animals, spending most of their time foraging, digging, and basking near their burrows. They are diurnal, meaning they are active during the day.

Signs of Infestation

Burrows: The most obvious sign is the presence of numerous small to medium-sized holes in the ground, often appearing in lawns, gardens, under decks, or near foundations. These are their burrow entrances.
Mounds of Soil: Freshly dug soil around the burrow entrances indicates recent activity.
Chewed Plants: Evidence of nibbled foliage, stems, and bulbs in gardens points to their feeding habits.
Damaged Structures: Sometimes, they can gnaw on wooden decks, fences, or even electrical wires if they gain access to crawl spaces.

Why Ground Squirrels Become a Problem

Several factors contribute to ground squirrels becoming a nuisance in our yards.

Habitat Suitability

Food Sources: Well-maintained lawns, gardens, and fruit-bearing trees provide ample food. Bird feeders can also be an attractive, albeit unintended, food source.
Shelter: Grassy areas, shrubs, and overgrown vegetation offer ideal cover and nesting sites. Undisturbed soil for burrowing is also essential.
Lack of Natural Predators: In urban and suburban environments, natural predators like hawks, foxes, and snakes may be scarce, allowing ground squirrel populations to grow unchecked.

Their Burrowing Impact

Lawn Damage: The most visible impact is the creation of numerous holes, which can trip hazards and make mowing difficult.
Root Damage: Burrowing activity near trees and shrubs can damage their root systems, weakening the plants and making them susceptible to disease and drought.
Structural Concerns: In some cases, extensive burrowing beneath foundations or patios can compromise their integrity.

Strategies for Ground Squirrel Control

Effective ground squirrel control involves a multi-faceted approach. Relying on a single method is rarely as successful as combining several strategies.

Prevention: Making Your Yard Less Appealing

The first line of defense in ground squirrel control is prevention. Making your yard less inviting can deter them from establishing a presence.

Eliminating Food Sources

Secure Trash Cans: Ensure garbage cans have tight-fitting lids.
Clean Up Fallen Fruit and Nuts: Regularly collect any fallen produce from fruit trees and nut trees.
Manage Bird Feeders: If you have bird feeders, consider squirrel-proof designs or place them in areas where squirrels have difficulty accessing them. Clean up spilled seeds regularly.
Pet Food: Avoid leaving pet food outdoors overnight.

Reducing Shelter and Cover

Trim Vegetation: Keep lawns mowed and trim dense shrubs and ground cover, especially near foundations.
Clear Debris: Remove piles of leaves, woodpiles, and other debris where squirrels might seek shelter or build nests.
Seal Entry Points: Inspect your home’s foundation, decks, and sheds for any gaps or openings that could provide shelter or access to crawl spaces. Seal these with sturdy materials like hardware cloth or metal flashing.

Deterrents: Discouraging Their Presence

While prevention is key, you might need to actively deter squirrels already present or those considering your yard.

Scent and Taste Deterrents

Natural Repellents: Some strong scents can deter ground squirrels. These can include:
- Castor Oil: Applied around burrows and garden areas.
- Peppermint Oil: Sprayed on plants or cotton balls placed near entrances.
- Garlic or Chili Powder: Sprinkled around vulnerable areas.
- Predator Urine: Available commercially, the scent can mimic the presence of natural predators.
Important Note: Natural repellents often require frequent reapplication, especially after rain or irrigation, and their effectiveness can vary.

Auditory and Visual Deterrents

Motion-Activated Sprinklers: These can startle squirrels with a burst of water when they approach.
Reflective Objects: Shiny objects like old CDs, aluminum foil strips, or reflective tape can sometimes deter them through light reflection and movement.
Ultrasonic Devices: These emit high-frequency sounds intended to be unpleasant to squirrels. Their effectiveness is debated, and they may only provide temporary relief.

Physical Barriers and Exclusion

Hardware Cloth: This sturdy wire mesh can be used to cover vulnerable plants, create barriers around garden beds, or seal off burrow entrances temporarily. Ensure the mesh is buried a few inches into the ground to prevent digging underneath.
Chicken Wire: While less sturdy than hardware cloth, it can still be effective for protecting smaller plants.
Netting: Fine netting can be draped over plants, especially fruit-bearing bushes, to prevent access.

Humane Removal: Trapping and Relocation

If deterrents and preventative measures aren’t enough, humane squirrel removal might be necessary. Ground squirrel trapping is a common method.

Live Trapping Methods

Types of Traps: Live traps, often called Havahart traps, are designed to catch animals without harming them. They come in various sizes, so choose one appropriate for ground squirrels.
Baiting the Trap:
- Bait Options: Peanut butter, sunflower seeds, oats, or small pieces of fruit are effective baits.
- Placement: Place the bait just inside the trap, and a small amount leading into the trap to entice the squirrel.
- Pre-baiting: Leave the trap open and unbaited for a few days so squirrels become accustomed to it as a food source without fear. Then, set it with bait.
Trap Placement: Place traps near active burrow entrances or along commonly used pathways.
Checking Traps: Check traps frequently, at least twice a day (morning and evening). It’s crucial to avoid leaving animals trapped for extended periods, especially in hot or cold weather.

Relocation Considerations

Legalities: Before relocating any wildlife, check your local and state regulations. Some areas have restrictions on trapping and relocating certain species.
Distance: If relocation is permitted, move the squirrel several miles away from your property to a suitable habitat (e.g., a wooded area with a water source) to minimize the chance of its return.
Ethical Relocation: Ensure the new location has a suitable food and shelter supply and is not already densely populated by other squirrels.

Dealing with Burrows

Addressing the burrows themselves is a vital part of ground squirrel control.

Sealing Burrows

Timing: The best time to seal burrows is after you have successfully trapped and removed the squirrels, or during their inactive periods (e.g., winter).
Materials: Use a mixture of soil, gravel, and possibly concrete or cement to fill the holes.
Depth: Ensure the fill material is packed down firmly and extends deep enough to prevent re-digging.

Fumigation (Use with Extreme Caution)

Limited Application: In some cases, for persistent infestations in inaccessible areas like under sheds, burrow fumigation might be considered.
Professional Application Recommended: This is generally not recommended for DIY application due to safety risks and potential harm to non-target species or the environment. If considering this, consult with a pest control professional.
Safety First: Always follow product instructions precisely and take all necessary safety precautions.

Ground Squirrel Extermination: When and How

Ground squirrel extermination is a more drastic measure and should be considered a last resort after all other methods have failed, especially given the importance of humane practices.

Considerations for Extermination

Non-Target Species: Many extermination methods can inadvertently harm other wildlife, pets, or even beneficial insects.
Environmental Impact: Certain rodenticides can have environmental consequences if they enter the food chain.
Legal Restrictions: The use of certain poisons and methods of ground squirrel extermination may be regulated or prohibited in your area.

Approved Methods (Professional Use Recommended)

Rodenticides: If rodenticides are used, opt for those specifically labeled for ground squirrels and follow all label instructions meticulously. It’s often best to have these applied by a licensed pest control professional.
- Placement: Rodenticides are typically placed in tamper-resistant bait stations to prevent access by pets and children.
- Careful Monitoring: Monitor bait stations and dispose of dead rodents promptly and safely to prevent secondary poisoning of scavengers.
Professional Pest Control: A professional exterminator can assess the situation and recommend the most appropriate and legal methods for your specific needs. They have the expertise and equipment to handle ground squirrel extermination safely and effectively.

Preventing Future Infestations: Long-Term Solutions

Once you’ve managed an active infestation, the focus shifts to long-term prevention.

Maintaining a Squirrel-Resistant Yard

Regular Lawn Care: Keep your lawn mowed and free of excessive thatch, which can provide cover.
Garden Bed Management: Consider raised garden beds with wire mesh buried around the perimeter to prevent burrowing.
Strategic Planting: Avoid planting attractive plants near the foundation of your home.

Ongoing Vigilance

Regular Inspections: Periodically inspect your yard for new burrow activity or signs of damage.
Prompt Action: Address any new issues immediately before they escalate into a full-blown infestation.
Community Effort: If your neighbors are also experiencing ground squirrel problems, consider a coordinated approach to yard pest control.
