Deciphering Armadillo Behavior: Why They Dig
Before we can effectively deter armadillos, it’s helpful to understand why they are drawn to your yard in the first place. Armadillos primarily seek food and shelter.
Food Sources
The primary attraction for armadillos is the abundance of insects and other invertebrates found in healthy soil. This includes:
- Grubs: The larval stage of beetles, grubs are a favorite food.
- Earthworms: These are a staple in the armadillo diet.
- Ants and Termites: Armadillos will readily dig into ant mounds and termite nests.
- Other Invertebrates: This can include beetles, spiders, and even small reptiles or amphibians if they encounter them.
A well-watered, fertilized lawn with a rich population of these creatures is essentially an all-you-can-eat buffet for an armadillo.
Shelter Needs
Armadillos also create burrows for shelter and breeding. They prefer areas with loose soil and cover, such as:
- Dense Vegetation: Shrubs, bushes, and tall grasses provide concealment.
- Woodpiles and Debris: These offer protection and attract insects.
- Underneath Structures: Porches, sheds, and decks can be ideal burrowing sites.
- Compost Piles: These offer both warmth and a plentiful food source.
Effective Strategies for Armadillo Deterrence
Deterring armadillos involves a multi-pronged approach, focusing on making your yard unappealing and implementing physical barriers. We’ll explore various methods for keeping armadillos away.
1. Modifying Your Yard for Armadillo Exclusion
The most sustainable way to deter armadillos from your yard is to remove what attracts them. This involves armadillo proofing yard spaces by targeting their food and shelter needs.
Reducing Insect Populations
- Limit Grubs: This is perhaps the most impactful step. Grubs feed on grass roots, causing brown patches. By controlling grubs, you reduce a primary food source.
- Beneficial Nematodes: These microscopic roundworms are natural predators of grubs and other soil-dwelling pests. They are safe for pets and humans.
- Milky Spore: This is a bacterium that specifically targets Japanese beetle grubs. It takes a few seasons to establish but provides long-term control.
- Organic Insecticides: If chemical solutions are necessary, opt for organic or naturally derived insecticides that target grubs specifically. Always follow product instructions carefully.
- Minimize Earthworm Appeal: While earthworms are beneficial for soil health, a dense population can attract armadillos. Avoid over-watering, as this can create a moister environment that earthworms thrive in.
- Keep Ants and Termites in Check: Address any ant hills or termite infestations promptly using appropriate control methods.
Eliminating Shelter Opportunities
- Clear Debris: Remove woodpiles, rock piles, leaf litter, and any other debris that can provide hiding places or attract insects.
- Secure Outbuildings: Ensure sheds, garages, and decks are sealed to prevent armadillos from burrowing underneath.
- Manage Compost Piles: While compost is great for your garden, a poorly managed compost pile can be an armadillo magnet. Keep it well-turned and contained.
Armadillo Lawn Care Practices
- Aeration and Dethatching: Healthy, well-aerated turf is less appealing to burrowing animals. Dethatching removes the thick layer of thatch that can hold moisture and harbor insects.
- Watering Wisely: Avoid over-watering your lawn, as excessive moisture can attract earthworms and other prey. Water deeply but less frequently.
- Choose Appropriate Plants: Some plants are less appealing to armadillos due to their taste or texture. Consider planting native species that are naturally more resistant.
2. Implementing Armadillo Repellents
Armadillo repellent options vary from homemade concoctions to commercial products. The effectiveness of these can differ, and regular application is often necessary.
Natural Armadillo Deterrents
Many homeowners prefer natural armadillo deterrents due to concerns about chemicals.
- Castor Oil: A strong-smelling oil, castor oil is often cited as an effective armadillo repellent. It can be mixed with water and dish soap to create a spray that can be applied to lawns and gardens. The idea is that it makes the ground distasteful or causes digestive upset if ingested.
- Recipe Suggestion: Mix 1-2 tablespoons of castor oil with 1 tablespoon of liquid dish soap in a gallon of water. Apply generously to affected areas. Reapply after rain.
- Essential Oils: Certain strong-smelling essential oils, such as peppermint oil, eucalyptus oil, and clove oil, are believed to deter armadillos due to their potent aromas. These can be diluted with water and sprayed.
- Cayenne Pepper and Chili Powder: The capsaicin in these spices can be irritating to an armadillo’s sensitive nose and feet. Sprinkle liberally around burrows and problem areas. Be cautious with this method, as it can also irritate pets and children.
- Garlic: The strong odor of garlic is thought to be unappealing to armadillos. Crushed garlic or garlic spray can be applied to the soil.
- Ammonia-Soaked Rags: Ammonia has a strong, pungent smell that can be a deterrent. Soak rags in ammonia and place them strategically around the perimeter of your yard or near burrow entrances. This needs frequent reapplication as the smell dissipates.
Commercial Armadillo Repellents
Various commercial repellents are available on the market, often containing ingredients like castor oil, urea, or essential oils.
- Granular Repellents: These are sprinkled onto the lawn and activated by moisture. They typically work by making the soil unpalatable.
- Liquid Sprays: These are applied directly to the lawn and garden areas.
- Electronic Repellents: Ultrasonic devices emit high-frequency sounds that are meant to disturb armadillos. Their effectiveness is often debated, and they may only be effective over a small area.
Important Note on Repellents: Repellents generally work best when used as a preventative measure or to encourage an animal to move from an area they have already established. They are often less effective at driving an animal out of an existing burrow. Consistent reapplication is key, especially after rain.
3. Physical Barriers and Exclusion
Physical barriers are a more direct and often more effective method for armadillo proofing yard areas and preventing future damage.
Fencing
- Height and Depth: Armadillos are not strong climbers, but they are persistent diggers. A fence needs to be at least 18-24 inches high. Crucially, it must be buried at least 6-12 inches into the ground to prevent them from digging underneath.
- Material: Sturdy materials like hardware cloth, welded wire mesh, or vinyl-coated chain-link fencing are suitable. Ensure the mesh is small enough (e.g., 1/2 inch) to prevent armadillos from squeezing through.
- Burying the Base: For maximum effectiveness, the bottom edge of the fence should be bent outward at a 90-degree angle and buried underground. This creates an “apron” that discourages digging.
Sealing Entry Points
- Under Decks and Porches: If armadillos are burrowing under these structures, you need to seal all openings. Use sturdy materials like hardware cloth or concrete barriers.
- Around Foundations: Inspect the foundation of your home and any outbuildings for gaps or holes and seal them.
Burrow Removal and Landscaping
- Armadillo Burrow Removal: If you have existing burrows, you may need to address them. Once an armadillo has vacated a burrow (which you can sometimes determine by lack of activity for a few days), you can fill it in with soil and compact it. Adding deterrents to the filled burrow area can help prevent reoccupation.
- Landscaping Modifications: Avoid dense, overgrown vegetation near your home or garden areas. Keep lawns mowed and tidy.
4. Trapping and Relocation (Use with Caution)
Trapping can be a way to deal with a persistent armadillo problem, but it’s not always the most effective long-term solution and can have legal implications depending on your location.
- Live Traps: Live traps designed for small to medium-sized animals can be used. Place bait such as earthworms, grubs, or canned cat food inside.
- Placement: Set traps near active burrows or along frequently used pathways.
- Relocation: If you trap an armadillo, relocation is a common practice. However, it’s important to be aware of local regulations regarding wildlife trapping and relocation. In many areas, it is illegal to relocate wildlife, or there are specific guidelines to follow. Furthermore, relocated animals may struggle to survive in unfamiliar territory or may simply be replaced by other armadillos.
- Humane Considerations: Check traps frequently to ensure the animal is not distressed or injured. Wear gloves when handling traps and any captured animals to protect yourself from potential diseases.
5. When to Call Professionals
If you’ve tried multiple methods without success, or if you have a severe infestation, it may be time to consider professional pest control for armadillos.
- Wildlife Removal Services: Professional wildlife removal services have the expertise and tools to safely and effectively remove armadillos from your property. They can also advise on the best long-term armadillo proofing yard strategies.
- Integrated Pest Management (IPM): Professionals often employ Integrated Pest Management strategies, which combine multiple approaches for a more sustainable solution.

Frequently Asked Questions (FAQ)
Q1: Can armadillos hurt my pets?
While armadillos are not aggressive, they can carry diseases like leprosy, though transmission to humans or pets is rare. Their primary defense is to dig away from a threat or curl into a ball. However, if cornered, they might scratch or bite defensively. It’s best to supervise pets when they are outdoors and keep them away from armadillos.
Q2: Are armadillos nocturnal?
Armadillos are primarily nocturnal or crepuscular (active at dawn and dusk), but they can sometimes be seen foraging during the day, especially during cooler weather or if their food source is abundant and they feel secure.
Q3: How do I know if the armadillo has left its burrow?
Look for signs of recent activity. If there are no fresh diggings, droppings, or sounds coming from the burrow for a couple of days, it’s likely empty. You can also try placing a bit of bait near the entrance and seeing if it’s disturbed.
Q4: Will a dog chase away armadillos?
Some dogs may try to chase armadillos, but they are rarely effective deterrents. Armadillos are tough and can sometimes injure a curious dog. Relying solely on a dog is not a guaranteed solution.
Q5: How quickly do repellents work?
The effectiveness and speed of armadillo repellent vary. Natural repellents like castor oil may start working within a few days to a week, but require consistent reapplication. Commercial repellents may have slightly faster results, but again, consistency is key.
Q6: Is it legal to kill armadillos?
Legality varies by region. In many areas, armadillos are considered wildlife and are not protected by hunting laws. However, it is often illegal to trap and relocate them without proper permits, or to use certain methods of control. Always check your local wildlife regulations before taking action.
Q7: What is the best time of year to address armadillo problems?
Spring and fall are often peak times for armadillo activity as they prepare for breeding and seek food before winter. Addressing issues during these periods can be particularly effective. However, armadillos can be active year-round, so vigilance is always advised.
By implementing these strategies, you can effectively deter armadillos from your yard, protect your landscaping, and enjoy a pest-free outdoor space. Remember that persistence and a combination of methods are often the most successful approach to armadillo control.
