Why Armadillos Visit Your Yard
Armadillos, particularly the nine-banded armadillo, are attracted to yards for a few key reasons:
- Food Source: Their primary diet consists of insects, grubs, ants, termites, and other invertebrates found in the soil. A lawn rich in these tasty treats is a major draw.
- Shelter: They need safe places to rest and build burrows. Loose soil, dense shrubbery, or overgrown areas provide ideal conditions for burrow construction.
- Moisture: Armadillos prefer damp soil, which makes lawns and gardens after rain or watering particularly appealing for foraging.
Identifying Armadillo Damage
Recognizing the signs of armadillo activity is the first step in effective armadillo control methods. Look for:
- Small, cone-shaped holes: These are the most common indicators. Armadillos use their snouts and claws to dig for food, leaving behind these distinctive divots, typically only an inch or two deep.
- Larger burrow entrances: If an armadillo decides to make your yard its home, you might find more substantial burrow openings, often at the base of structures, under sheds, or within dense vegetation. These can be several inches wide.
- Upturned sod or flower bulbs: In their relentless search for grubs and insects, armadillos can disturb lawns and gardens significantly.
Proven Methods to Deter Armadillos
Keeping armadillos out of your yard involves a multi-pronged approach. The goal is to make your property uninviting and inaccessible to them.
1. Habitat Modification: Making Your Yard Less Appealing
Armadillos are looking for food and shelter. By removing these essentials, you can effectively deter armadillos.
Reducing Food Sources
- Grub Control: The most effective way to stop armadillos digging for food is to eliminate the food source itself. Apply grub control treatments to your lawn. Look for products containing beneficial nematodes or specific insecticides that target grubs. Follow product instructions carefully for best results.
- Clean Up Yard Debris: Armadillos love to hide and forage in piles of leaves, mulch, or wood. Regularly clean up yard debris. This removes hiding spots and reduces the insect populations that thrive in these areas.
- Secure Trash Cans: While not their primary food source, armadillos may occasionally investigate garbage. Ensure your trash cans have tight-fitting lids to avoid attracting them.
- Reduce Outdoor Lighting: Bright lights can attract insects, which in turn attract armadillos. Consider using motion-activated lights or reducing the overall brightness of your outdoor lighting.
Eliminating Shelter Opportunities
- Seal Entry Points: Armadillos often burrow under sheds, decks, porches, and even homes. Inspect these areas and seal any gaps or openings with sturdy materials like wire mesh or solid barriers. This is a crucial aspect of armadillo proofing.
- Trim Vegetation: Overgrown bushes and dense ground cover offer excellent hiding places. Keep your lawn mowed and trim back any overgrown vegetation, especially near structures.
- Fill In Old Burrows: If you find an existing burrow, especially one that appears abandoned, fill it in. This discourages them from returning or reusing the space.
2. Physical Barriers: Fencing and Exclusion
Physical barriers are highly effective in preventing armadillos from entering your yard.
Armadillo Fencing Solutions
- Types of Fencing: The most effective armadillo fencing is sturdy and extends underground.
- Hardware Cloth or Chicken Wire: Use a strong gauge hardware cloth (¼-inch or ½-inch mesh) or heavy-duty chicken wire.
- Height: The fence should be at least 2 feet tall to prevent them from easily jumping over.
- Burial Depth: Crucially, the fencing needs to be buried at least 1 foot into the ground. Armadillos are excellent diggers, and if the fence doesn’t go underground, they will simply dig under it.
- Installation:
- Dig a trench along the perimeter where you want to install the fence.
- Place the fencing material in the trench, ensuring at least 1 foot is buried.
- Bend the bottom portion of the fence outwards at a 90-degree angle into the ground. This creates an “L” shape that makes it harder for them to dig under.
- Backfill the trench securely.
- Attach the top of the fence to sturdy posts or existing structures.
- Considerations for Fencing:
- Aesthetics: While effective, fencing can be visually unappealing. Consider landscaping around it to soften the look.
- Scope: Fencing an entire yard can be expensive and labor-intensive. Focus on key areas like gardens or areas close to your home.
Humane Armadillo Exclusion Techniques
Humane exclusion is about making your yard uninviting without harming the armadillos.
- Seal Burrow Entrances: If an armadillo has burrowed under a structure, wait until you are sure it is empty (often at night, as they are nocturnal). Then, securely seal the entrance with wire mesh or concrete. This is a key part of humane armadillo exclusion.
- One-Way Doors: For temporary exclusion from specific areas, you can install one-way doors. These allow the armadillo to exit but not re-enter. This is a good option if you have a specific burrow you need to clear.
3. Repellents: Natural and Commercial Options
While not always 100% effective on their own, repellents can be a useful part of a comprehensive strategy to deter armadillos.
Natural Armadillo Deterrents
Many homeowners prefer natural armadillo deterrents due to their safety for pets and the environment.
- Castor Oil: Armadillos dislike the taste and smell of castor oil. Mix a solution of 1 part castor oil with 4 parts water, and spray it liberally around the perimeter of your yard, gardens, and any areas they frequent. Reapply after rain.
- Cayenne Pepper/Chili Powder: The spicy nature of these can be irritating to armadillos. Sprinkle them generously around garden beds and burrow entrances. Be cautious if you have pets or small children, as it can also irritate them.
- Coffee Grounds: Some gardeners report success using used coffee grounds. The scent and texture might be unappealing.
- Garlic: The strong smell of garlic can also be a deterrent. You can crush garlic cloves and scatter them, or use garlic-based sprays.
- Essential Oils: Certain essential oils like peppermint, eucalyptus, or citronella can be mixed with water and sprayed. These need frequent reapplication.
Commercial Armadillo Repellent Products
Various commercial armadillo repellent products are available. These often contain ingredients like castor oil, urea, or essential oils.
- Granular Repellents: These are typically spread on the lawn and watered in.
- Liquid Sprays: Similar to natural sprays, these are applied to affected areas.
- Effectiveness: Read reviews and follow instructions carefully. Commercial repellents can sometimes be more potent than DIY solutions, but they still require consistent application and may not be fully effective on their own.
Important Note on Repellents: Repellents work best when they are part of a larger strategy. They can help deter armadillos from returning to an area that has already been made less hospitable.
4. Trapping and Relocation (Use with Caution)
Trapping and relocating armadillos can be considered, but it’s important to understand the implications and local regulations. This is a more direct armadillo control method.
Live Trapping
- Trap Type: Use a live trap designed for medium-sized animals. Place bait like earthworms, grubs, or fruit inside.
- Placement: Position the trap in areas where you’ve seen the most activity.
- Checking Traps: Check traps frequently throughout the day. You do not want to leave an animal trapped for extended periods, especially in extreme weather.
Relocation Considerations
- Legality: Relocation regulations vary significantly by state and local municipality. Many areas prohibit the relocation of wildlife. It’s crucial to check with your local wildlife agency or animal control before trapping and relocating.
- Effectiveness: Simply relocating an armadillo doesn’t solve the root problem if your yard remains a food and shelter haven. Another armadillo will likely move in.
- Stress: Relocation can be stressful for the animal.
Instead of trapping and relocating, focusing on habitat modification and exclusion is generally a more sustainable and humane approach to remove armadillos from garden areas and yards.
Preventing Armadillo Damage: A Proactive Approach
Prevent armadillo damage by being proactive. The best time to implement these strategies is before armadillos become a problem.
- Regular Lawn Maintenance: Keep your lawn mowed, and avoid excessive watering that keeps the soil consistently damp.
- Inspect Your Property: Periodically check for early signs of armadillo activity, such as small holes or disturbed soil.
- Garden Protection: For vulnerable gardens, consider using armadillo fencing around individual beds or the entire garden area. Raised garden beds can also make it harder for them to dig.
- Educate Neighbors: If your neighbors are also experiencing armadillo issues, working together can be more effective.

Frequently Asked Questions (FAQ)
Q: What is the best time of year to try and keep armadillos out of my yard?
A: The best time is spring and fall when they are most active in seeking food and shelter before extreme weather sets in. However, these methods can be implemented year-round.
Q: Can I use a dog to keep armadillos away?
A: Some dogs may chase or deter armadillos, but this is not a reliable method for armadillo control. Dogs can also get injured if they try to fight an armadillo, as armadillos can defend themselves with their claws.
Q: Will armadillos hurt my pets?
A: Armadillos are generally not aggressive towards pets, but they can defend themselves if cornered. Their claws can cause injury. More commonly, armadillos can carry leprosy, which can be transmitted to dogs if they come into close contact or eat an infected armadillo.
Q: How deep do armadillos dig their burrows?
A: Armadillo burrows can vary in depth, but the main entrance is usually a few inches wide and can extend several feet into the ground. The tunnels are typically just wide enough for the animal to pass through.
Q: Are armadillos dangerous to humans?
A: Armadillos are not inherently dangerous to humans. They are shy and will typically try to escape rather than fight. The primary concern is the potential transmission of diseases like leprosy if an armadillo is handled or if a pet interacts with one.
Q: What is the most effective humane way to remove armadillos from a garden?
A: The most effective humane methods involve making the garden less appealing by removing their food source (grubs) and preventing access. Installing sturdy, buried fencing is highly effective. Using natural deterrents around the garden perimeter can also help deter armadillos.
By combining these strategies, you can create an inhospitable environment for armadillos and protect your yard from their digging and damage. Remember that consistency is key, and a multi-faceted approach will yield the best results for long-term armadillo proofing.
