Why Armadillos Visit Your Yard
Armadillos are primarily attracted to yards that offer a plentiful food source and suitable places to burrow. Their diet consists mainly of insects like grubs, beetles, ants, and termites, which they locate by sniffing the ground and digging. Yards with lush lawns, compost piles, or areas with abundant leaf litter provide ideal hunting grounds.
Food Sources That Attract Armadillos
- Insects and Grubs: The primary attraction. Armadillos are expert insectivores.
- Earthworms: Found in moist, well-maintained soil.
- Small Vertebrates: Occasionally, they might consume small frogs, snakes, or bird eggs if easily accessible.
Shelter Needs for Armadillos
- Burrows: Armadillos dig burrows for shelter, protection from predators, and to escape extreme temperatures. They prefer soft, sandy soil, often found near foundations, under sheds, or in dense vegetation.
- Den Sites: Abandoned burrows of other animals, dense brush piles, and areas under decks or porches can also serve as temporary shelters.
Effective Strategies for Keeping Armadillos Away
Successfully keeping armadillos out of your yard involves a multi-pronged approach. The most effective methods focus on making your yard less appealing to them and physically blocking their access.
1. Eliminating Food Sources
The most sustainable way to deter armadillos is to remove what draws them in – their food.
Reducing Insect Populations
- Proper Lawn Care: Maintain a healthy lawn that is less susceptible to grub infestations. Avoid over-watering, which can encourage grub growth.
- Beneficial Nematodes: Introduce beneficial nematodes into your soil. These microscopic worms are natural predators of grubs and other soil-dwelling insects that armadillos feed on.
- Natural Insecticides: If an infestation is severe, consider using organic or natural insecticides to control grub populations. Always follow product instructions carefully.
- Avoid Attracting Other Pests: Keep trash cans sealed and clean up fallen fruit or pet food, as these can attract insects that armadillos also consume.
Clearing Potential Shelters
- Remove Debris: Clear away brush piles, leaf litter, and woodpiles. These provide hiding places and can harbor insects.
- Secure Outdoor Areas: Block off areas under decks, porches, and sheds. Armadillos often use these as convenient places to dig burrows.
2. Employing Armadillo Repellent Strategies
While not always foolproof, certain smells and substances can act as an armadillo repellent, making your yard less attractive.
Natural Armadillo Deterrents
Many homeowners prefer natural armadillo deterrents to avoid harsh chemicals.
- Castor Oil: A mixture of castor oil and water sprayed on the lawn can deter armadillos. The oil irritates their sensitive skin and noses, making them avoid treated areas. Mix about 2 tablespoons of castor oil with 1 gallon of water and a few drops of liquid dish soap (to help the oil mix with water). Apply this mixture to the lawn and garden areas. Reapply after rain.
- Cayenne Pepper: Sprinkle cayenne pepper around the perimeter of your yard or near burrow entrances. The spice can be irritating to their noses and paws.
- Garlic and Onion: Strong smells can be off-putting. Crushed garlic or onions, or sprays made from them, might deter armadillos.
- Peppermint Oil: Similar to other strong scents, peppermint oil can be used as a repellent. Mix with water and spray.
Commercial Armadillo Repellents
There are several commercial armadillo repellent products available, often made with essential oils or predator urine.
- Granular Repellents: These are sprinkled on the lawn and can be effective for a period.
- Liquid Sprays: Similar to homemade sprays, these are applied to specific areas.
- Predator Urine: Products containing the urine of natural armadillo predators (like coyotes or bobcats) can create a perceived threat and drive them away.
Important Note on Repellents: Repellents are often most effective when used in conjunction with other methods, like armadillo exclusion. They can also lose effectiveness over time or after rain, requiring reapplication.
3. Implementing Armadillo Exclusion Techniques
Armadillo exclusion involves physically preventing them from entering your yard or specific areas. This is often the most reliable long-term solution.
Armadillo Fencing
The most effective form of armadillo fencing needs to be installed correctly to prevent them from digging under or going over it.
- Height and Depth: Fencing should be at least 2 to 3 feet tall. Crucially, it must extend at least 12 inches underground, bent outwards at a 90-degree angle (an “L” shape), buried shallowly. This buried section prevents them from digging underneath.
- Material: Sturdy materials like hardware cloth (1/2 inch mesh or smaller) or chicken wire are suitable. Metal fencing is more durable than plastic netting.
- Maintenance: Regularly check the fence for any breaches or loose sections.
Securing Burrowing Areas
- Under Decks and Sheds: Use sturdy materials like hardware cloth or concrete to block all openings leading under decks, sheds, or crawl spaces. Ensure there are no gaps.
- Landscaping Modifications: Avoid dense shrubbery near the house foundation, as this can provide cover for burrowing. Consider using gravel or rocks in areas prone to digging.
4. Addressing Existing Armadillo Burrows
If armadillos have already established burrows on your property, addressing these is a key part of armadillo removal and armadillo burrow prevention.
Locating Burrows
- Entrance Holes: Look for distinctive U-shaped or arched holes, typically 4-7 inches wide and 3-5 inches high.
- Digging Patterns: Observe areas where the soil has been disturbed and dug up, especially around the lawn and gardens.
Humane Methods for Discouraging Burrow Use
- Flooding: If possible and practical, gently flooding a burrow can encourage occupants to leave. Use a hose to introduce water slowly. Do not blast water, as this can injure the animal.
- Obstruction: Once you believe the burrow is vacant (observe for several days), block the entrance with rocks, soil, or hardware cloth. This prevents re-occupation and discourages new burrowing in the same spot.
- Commercial Burrow Baits: Some products are designed to be placed in burrows that may deter animals, but these should be used with caution to ensure they are effective and humane.
5. The Role of Professional Armadillo Removal
In cases where DIY methods are ineffective or you are dealing with a persistent problem, professional armadillo removal services can be a viable option.
- Expertise: Wildlife removal specialists have the experience and knowledge to safely and humanely capture and relocate armadillos.
- Trapping: Professionals may use live traps, baited with suitable food items like earthworms or grubs, to capture the animals. It is crucial to check local regulations regarding trapping and relocating wildlife.
- Integrated Pest Management: Many professionals offer integrated pest management plans that combine exclusion, habitat modification, and trapping for a comprehensive solution.
What Not to Do: Avoiding Harmful Practices
When dealing with armadillos, it’s essential to prioritize humane methods.
- Lethal Methods: Avoid using poisons or lethal traps. These are inhumane, can harm non-target animals (including pets and beneficial wildlife), and may be illegal in your area.
- Aggressive Confrontation: Do not attempt to corner or directly confront an armadillo. While generally not aggressive, they can bite if they feel threatened.
- Sealing Active Burrows: Never seal a burrow entrance if you suspect it is occupied. This traps the animal inside, leading to suffering and potential death.
Creating an Armadillo-Resistant Yard
Here’s a summary of how to make your yard less attractive and accessible to armadillos, focusing on preventing armadillo digging:
Key Strategies for Prevention
- Maintain a healthy, well-maintained lawn and garden. This reduces insect populations.
- Regularly clear away debris like leaf litter, woodpiles, and brush.
- Install secure fencing that extends underground with an outward bend.
- Block access to crawl spaces under structures.
- Use natural or commercial repellents as a supplementary measure.
Common Questions About Armadillos in Yards
What do armadillos eat?
Armadillos primarily eat insects, including grubs, beetles, ants, termites, and earthworms. They will also consume small invertebrates and occasionally small vertebrates.
Are armadillos dangerous?
Armadillos are generally not dangerous to humans or pets. They are shy and will typically flee if approached. However, they can bite if cornered or threatened, and their claws can cause injury. They can also carry diseases like leprosy, though transmission to humans is extremely rare.
Why are armadillos digging in my yard?
Armadillos dig in yards to find food (insects and grubs) and to create burrows for shelter and protection.
What is the best armadillo deterrent?
The best armadillo deterrent is a combination of armadillo exclusion (like secure fencing) and habitat modification (removing food sources and shelter). Repellents can offer supplementary protection.
Can I use ultrasonic devices to deter armadillos?
The effectiveness of ultrasonic devices for deterring armadillos is largely anecdotal and not scientifically proven. Armadillos rely heavily on their sense of smell and touch, not primarily on sound.
