Humane Ways: How To Get Rid Of Ground Squirrels In Your Yard
Can you get rid of ground squirrels humanely? Yes, there are several effective and humane methods for getting rid of ground squirrels in your yard, focusing on deterrence and exclusion rather than harm. Dealing with backyard squirrel problems can be frustrating, especially when burrowing squirrels damage your lawn, gardens, or even structures. This guide will explore various ground squirrel control strategies, from natural squirrel repellents to humane squirrel removal techniques, aiming to provide a comprehensive approach to eliminating ground squirrels and preventing their return.
Ground squirrels, often recognized by their habit of darting into burrows, can quickly become a nuisance. Their tunneling can destabilize soil, create tripping hazards, and damage plant roots. For those seeking pest control for squirrels that aligns with ethical practices, focusing on humane options is key. This involves understanding squirrel behavior and implementing solutions that deter them without causing unnecessary stress or harm.
Deciphering Ground Squirrel Behavior and Impact
Before diving into solutions, it’s crucial to grasp why ground squirrels are drawn to your yard and the extent of their impact.
Common Ground Squirrel Species:
* California Ground Squirrel: Ubiquitous in the western United States, known for extensive burrow systems.
* Thirteen-lined Ground Squirrel: Distinctive stripes, found in grasslands and open areas.
* Rock Squirrel: Often seen in rocky areas and open woodlands, capable of significant burrowing.
Why They Choose Your Yard:
* Food Sources: Abundant seeds, nuts, fruits, vegetables, and even ornamental plants. Gardens are a buffet for them.
* Shelter: Easy access to burrows for nesting, escaping predators, and overwintering. Well-maintained lawns and undisturbed areas offer ideal locations.
* Water: Access to water sources like bird baths or leaky spigots.
* Safety: Proximity to cover (bushes, woodpiles) to escape predators.
The Damage They Cause:
* Garden Destruction: Nibbled vegetables, damaged flowers, and uprooted seedlings.
* Lawn Damage: Extensive burrowing can create unsightly mounds of soil, create tripping hazards, and damage grass roots.
* Structural Damage: In some cases, burrowing near foundations or wooden structures can weaken them.
* Attracting Predators: While not a direct damage, their presence can attract larger predators like snakes or hawks, which might then become a concern for pets.
Humane Squirrel Removal: Strategies for a Peaceful Coexistence
Humane squirrel removal focuses on encouraging squirrels to leave your property and discouraging them from returning. This approach prioritizes live trapping and relocation, or better yet, making your yard an unattractive environment for them.
Natural Squirrel Repellents: Discouraging Unwanted Visitors
Natural squirrel repellents work by using scents or tastes that are unpleasant to squirrels but generally harmless. They are a great starting point for managing backyard squirrel problems.
Scents That Deter Ground Squirrels:
* Peppermint Oil: Strong minty scents are often disliked by rodents.
* Application: Soak cotton balls in peppermint oil and place them near burrows, entry points, or garden areas. Reapply weekly as the scent fades.
* Cayenne Pepper/Chili Powder: The capsaicin in peppers irritates squirrels’ noses and mouths.
* Application: Sprinkle liberally around plants, garden beds, and the perimeter of your yard. Reapply after rain.
* Garlic: The strong odor of garlic can be a deterrent.
* Application: Plant garlic cloves around your garden or use garlic spray (water mixed with minced garlic and a drop of dish soap).
* Castor Oil: This oil is known to upset squirrels’ digestive systems.
* Application: Mix castor oil with water and a mild detergent. Spray it around the base of plants or on surfaces squirrels frequent.
* Predator Urine: Urine from foxes or coyotes can signal danger to squirrels.
* Application: Available commercially, sprinkle around the perimeter of your property.
Taste Deterrents:
* Bitter Apple Spray: Safe for plants, but has a bitter taste that squirrels dislike.
* Application: Spray directly onto plants or bulbs you want to protect.
Important Considerations for Natural Repellents:
* Reapplication is Key: Natural repellents lose potency over time, especially after rain or irrigation. Consistent reapplication is vital for effectiveness.
* Targeted Application: Focus on areas where squirrels are most active – garden beds, near burrows, or favorite feeding spots.
* Combine Methods: Using a combination of scent and taste deterrents can be more effective than relying on a single product.
Making Your Yard Less Appealing: Habitat Modification
A primary strategy for ground squirrel control is to remove the attractants that draw them to your yard in the first place.
Eliminating Food Sources:
* Secure Trash Cans: Ensure all outdoor trash cans have tight-fitting lids.
* Clean Up Spilled Bird Seed: Bird feeders can be a major attractant. Clean up any spilled seed promptly. Consider squirrel-proof feeders.
* Harvest Ripe Produce: Don’t leave ripe fruits and vegetables on trees or the ground.
* Remove Fallen Nuts and Seeds: Regularly rake up nuts and seeds from trees.
* Pet Food: Do not leave pet food outdoors, especially overnight.
Removing Shelter and Hiding Spots:
* Clear Debris: Remove piles of wood, rocks, leaves, or brush where squirrels can hide or build nests.
* Trim Vegetation: Keep shrubbery and ground cover trimmed back from your house and garden areas. This reduces cover for squirrels to ambush your plants or escape predators.
* Seal Entry Points: Inspect sheds, decks, and the foundation of your home for any cracks or openings squirrels could use for shelter. Seal these with sturdy materials like hardware cloth or metal flashing.
Exclusion Techniques: Creating Physical Barriers
Exclusion involves using physical barriers to prevent squirrels from accessing specific areas, such as gardens or the space beneath your deck. This is a highly effective method for long-term ground squirrel control.
Garden Protection
Protecting your garden is a common backyard squirrel problem.
- Hardware Cloth or Chicken Wire:
- Application: Bury a skirt of ½-inch or ¼-inch hardware cloth or chicken wire around garden beds. Extend it at least 1 foot below the soil surface and 1-2 feet above ground. This prevents burrowing underneath and climbing over.
- Burying Technique: Dig a trench around the garden. Place the wire, then fold the bottom edge outwards at a 90-degree angle before backfilling. This “L” shape makes it harder for them to dig under.
- Row Covers or Netting:
- Application: Use lightweight netting or row covers draped over hoops to create a physical barrier over plants. Ensure the edges are secured firmly to the ground to prevent squirrels from getting underneath.
Protecting Structures and Foundations
Preventing burrowing squirrels from undermining your property is crucial.
- Hardware Cloth Skirts:
- Application: Attach ½-inch or ¼-inch hardware cloth around the perimeter of decks, porches, or any wooden structures where squirrels might burrow. Bury the bottom edge a few inches into the ground.
- Metal Flashing:
- Application: Install smooth metal flashing around the base of wooden posts or structures. Squirrels have difficulty gaining purchase on smooth surfaces.
Repelling Squirrels from Specific Areas
- Repellent Sprays: As mentioned earlier, natural sprays can be applied to plants or surfaces.
- Motion-Activated Sprinklers:
- Application: These devices detect movement and spray a burst of water, startling squirrels and encouraging them to leave. They are effective in deterring squirrels from gardens and open lawn areas.
Squirrel Trapping: Humane Removal and Relocation
When other methods fail, humane squirrel trapping can be an option for removing specific problem individuals. It’s essential to understand local regulations regarding trapping and relocation.
Live Trapping Methods
-
Types of Traps:
- Havahart Live Traps: These are common, humane live traps designed with triggers that close the doors once a squirrel enters. They come in various sizes. For ground squirrels, a medium or large trap is usually appropriate.
- Small Cage Traps: Similar in design, these are readily available at garden centers and hardware stores.
-
Baiting the Trap:
- Effective Baits: Peanut butter, nuts, seeds, apple slices, or oats are highly attractive to ground squirrels.
- Placement: Place a small amount of bait just inside the trigger plate and a trail leading into the trap.
- Pre-baiting: Leave the trap open for a few days with bait inside but no trigger mechanism set. This allows squirrels to get used to it as a food source without getting trapped, increasing your success rate when you do set it.
-
Trap Placement:
- Near Burrows: Place traps near active burrows or along frequently used pathways.
- Along Walls or Fences: Squirrels often travel along edges.
- Secure the Trap: Ensure the trap is stable on the ground so it doesn’t tip over.
-
Checking the Trap:
- Frequency: Check traps at least twice a day, ideally in the early morning and late afternoon.
- Minimize Stress: Squirrels can become stressed if left in a trap for extended periods, especially in hot weather.
-
Relocation:
- Regulations: Check local wildlife regulations for rules on trapping and relocating animals. Some areas prohibit relocation to prevent the spread of disease or to avoid disrupting existing wildlife populations.
- Distance: If relocation is permitted, take the squirrel at least 5-10 miles away from your property to a suitable habitat (e.g., a wooded area with a water source) where it is unlikely to return.
- Release: Release the squirrel gently by opening the trap door.
Ethical Considerations for Trapping:
* Avoid Trapping During Breeding Season: This can separate mothers from their young, leading to the death of dependent offspring.
* Handle with Care: Wear gloves when handling traps and squirrels, as they can bite or scratch if they feel threatened.
* Consider a Professional: If you’re uncomfortable with trapping or unsure about regulations, contact a local pest control service that specializes in humane animal removal.
Deterrents Beyond Scent: Auditory and Visual Methods
While less proven for ground squirrels compared to other pest control for squirrels, some auditory and visual deterrents might have a limited effect.
- Scare Tapes: Shiny, reflective tapes that flutter in the wind can sometimes startle squirrels.
- Decoys: Plastic owls or snakes placed strategically might offer temporary deterrence, but squirrels often get accustomed to them.
- Ultrasonic Devices: These emit high-frequency sounds that are meant to be unpleasant to rodents. Their effectiveness against ground squirrels is debated, and they may also affect pets.
Long-Term Prevention: Sustaining a Squirrel-Free Zone
The goal of any ground squirrel control program is to prevent them from becoming a recurring problem.
- Consistent Habitat Management: Regularly remove food sources, clear debris, and trim vegetation.
- Maintain Barriers: Ensure exclusion barriers like hardware cloth skirts remain intact and secure.
- Monitor and Respond: Keep an eye out for new burrowing activity or signs of squirrels returning. Address any new issues promptly before they escalate.
- Encourage Natural Predators: While not a direct control method, a healthy ecosystem with natural predators can help keep squirrel populations in check over the long term.
Identifying and Sealing Burrows
A critical step in ground squirrel control is identifying and then properly sealing their burrows. This makes it difficult for them to use your yard as their home.
Finding Active Burrows:
* Look for Fresh Mounds: Fresh soil pushed out of a hole is a clear indicator.
* Inspect Pathways: Follow trails of disturbed soil or vegetation.
* Listen: You might hear scurrying or chewing sounds.
Sealing Methods:
1. Flood the Burrows (Caution Advised): Some suggest flooding burrows with water. However, this can be ineffective if the burrow system is extensive and may even encourage them to dig elsewhere, potentially closer to structures. It’s also not a humane method if young are trapped inside.
2. The “Chase and Plug” Method:
* Timing: Best done in late fall or early spring when squirrels are less active or preparing to hibernate.
* Procedure: Gently encourage squirrels away from the burrow entrance (e.g., using a broom). Once the entrance is clear, immediately and firmly fill the burrow with soil, rocks, and gravel. Pack it down tightly.
* Reinforcement: Consider placing a wire mesh over the sealed area to deter re-digging.
Important Note on Sealing: It is crucial to ensure that no squirrels are inside the burrow before sealing it permanently. If you suspect young are present, wait until they are old enough to emerge on their own. This is where humane removal methods like trapping are often a better initial step to clear the burrow before sealing.
When to Call a Professional
If your ground squirrel problem is severe, persistent, or you are uncomfortable with any of these methods, it’s time to consult a pest control professional who specializes in humane wildlife management. They have the expertise and tools to implement effective strategies while adhering to safety and ethical standards.
When Professional Help is Recommended:
* Extensive Burrowing: If burrows are widespread or near critical structures.
* Persistent Infestations: If DIY methods are not yielding results.
* Safety Concerns: If you have pets or children and are worried about interactions.
* Legal Advice: For guidance on local wildlife regulations and trapping permits.
FAQ: Addressing Common Ground Squirrel Concerns
Q1: How do I know if it’s ground squirrels or another animal?
Ground squirrels are typically smaller than tree squirrels and are often seen darting into holes in the ground. They are diurnal, meaning they are active during the day. Their burrows are usually characterized by a distinct mound of soil at the entrance.
Q2: Are ground squirrels dangerous to humans or pets?
Ground squirrels are generally not aggressive towards humans. However, like any wild animal, they can bite if cornered or handled. They can also carry diseases, though the risk is low. Their main danger to pets is if a pet tries to dig them out of a burrow, which could lead to injury from bites or scratches.
Q3: What is the most humane way to get rid of ground squirrels?
The most humane methods involve deterring them through habitat modification, using natural repellents, and employing exclusion techniques. If trapping is necessary, live trapping and relocating them to a suitable habitat (where permitted) is considered humane.
Q4: Can I legally trap and relocate ground squirrels?
This varies significantly by location. Always check your local wildlife or animal control regulations before trapping and relocating any animal. Some areas have strict rules or prohibitions against it.
Q5: How can I prevent ground squirrels from coming back after I’ve removed them?
Long-term prevention involves consistently removing food sources, maintaining exclusion barriers, keeping your yard tidy (removing debris), and promptly addressing any new signs of burrowing.
By focusing on these humane and proactive strategies, you can effectively manage backyard squirrel problems and enjoy a yard free from the disruptions caused by burrowing squirrels. Remember that patience and consistency are key to successful ground squirrel control.
