What is the best way to stop armadillos from digging up my yard? The most effective approach to stop armadillos from digging up your yard involves a combination of preventative measures, deterrents, and, if necessary, humane removal.
Armadillos, with their distinctive bony armor and habit of digging for insects, can quickly turn a well-maintained lawn into a minefield of holes. These fascinating creatures, while beneficial in controlling insect populations, can cause significant armadillo damage control issues for homeowners. From unsightly divots to potential damage to sprinkler systems and foundations, armadillo digging can be a persistent problem. This comprehensive guide will delve into various armadillo yard solutions, offering practical advice on preventing armadillo digging and managing their presence.
Why Armadillos Dig
Before we can effectively stop armadillos from digging, it’s important to understand why they do it. Their primary motivation is food. Armadillos are insectivores, meaning their diet consists mainly of insects, grubs, earthworms, and other invertebrates found in the soil. They possess a keen sense of smell and can detect prey underground. Their powerful claws are perfectly designed for digging, allowing them to unearth their meals quickly.
Armadillos also dig for other reasons:
- Creating Burrows: They dig burrows for shelter, to escape predators, and to raise their young. These burrows can be extensive, often with multiple entrances and chambers.
- Seeking Water: During dry periods, they may dig in moist soil to find water.
- Cooling Off: Armadillos, being primarily nocturnal and sensitive to heat, may dig to find cooler soil during hot weather.
Identifying Armadillo Damage
Recognizing the signs of armadillo activity is the first step in addressing the problem. Armadillo digging typically creates shallow, conical holes or trenches, often about the size of a golf ball or slightly larger. You might see these holes scattered across your lawn, flowerbeds, or gardens.
Other signs include:
- Disturbed Soil: Loose soil or mounds of dirt where an armadillo has been foraging.
- Uprooted Plants: Smaller plants might be dislodged as the armadillo searches for food beneath them.
- Visible Trails: In softer soil, you might see the imprint of their bodies or claws.
Effective Armadillo Deterrence Strategies
Implementing armadillo deterrence measures is key to keeping them from turning your yard into their personal buffet and construction site. These strategies focus on making your yard less attractive and accessible to them.
1. Habitat Modification
Armadillos are attracted to environments that offer easy access to food and shelter. Modifying your yard to remove these attractants can be a highly effective armadillo repellent.
-
Reduce Insect Food Sources:
- Grub Control: Grubs are a favorite food of armadillos. Applying a grub control treatment to your lawn can significantly reduce their food supply. Consider organic or natural grub control methods if you prefer to avoid chemicals.
- Compost and Mulch Piles: These areas often harbor insects. Keep compost piles securely contained and consider moving them away from your house or main garden areas.
- Standing Water: Fix leaky faucets and irrigation systems. Armadillos may dig in moist areas for water.
-
Eliminate Shelter:
- Clear Debris: Remove brush piles, old lumber, rock piles, and dense vegetation where armadillos can hide and burrow.
- Seal Off Potential Shelter: If you have structures like sheds or decks with open undersides, consider sealing these areas to prevent armadillos from creating burrows underneath.
2. Physical Barriers for Armadillo Proofing
Creating physical barriers is a robust method for armadillo proofing your yard and preventing them from entering in the first place.
-
Fencing:
- Type of Fence: A sturdy fence made of galvanized steel or heavy-gauge wire mesh is most effective.
- Depth and Incline: The fence should be at least 2-3 feet tall. Crucially, it needs to be buried at least 12-18 inches deep into the ground. Armadillos are excellent diggers, so a fence that stops at ground level will be easily bypassed.
- L-Footer: For maximum effectiveness, bend the bottom 6 inches of the fence outward (forming an “L” shape) and bury it. This makes it harder for them to dig underneath.
- Material: Avoid using materials like chicken wire, which is too flimsy and easily breached.
-
Repellent Sprays and Granules (Commercial and Natural Armadillo Deterrents):
- Commercial Repellents: Several commercial repellents are available, often containing ingredients like castor oil, predator urine (coyote or fox), or capsaicin (hot pepper). These work by making the area smell or taste unpleasant to armadillos.
- Application: Follow product instructions carefully for application. Repellents typically need to be reapplied after rain or irrigation.
- Natural Armadillo Deterrents:
- Castor Oil: A common ingredient in natural repellents. It can be mixed with water and dish soap and sprayed on affected areas.
- Cayenne Pepper/Hot Sauce: While some suggest sprinkling these, their effectiveness is often short-lived, and they can be washed away easily by rain. They can also be irritating to pets and children.
- Predator Urine: The scent of natural predators can deter armadillos.
- Ammonia-Soaked Rags: Some anecdotal evidence suggests that placing rags soaked in ammonia in disturbed areas can deter them due to the strong smell. However, this can also be unpleasant for humans and pets.
3. Ultrasonic Devices
Ultrasonic devices emit high-frequency sound waves that are supposedly unpleasant to animals like armadillos.
- Effectiveness: The scientific consensus on the long-term effectiveness of ultrasonic devices for wildlife deterrence is mixed. Some users report success, while others find them ineffective.
- Placement: Ensure devices are placed strategically to cover the areas where armadillos are active.
Humane Armadillo Removal and Management
If deterrents are not enough, you may consider humane armadillo removal or more direct management tactics.
1. Live Trapping
Live trapping is a humane way to capture and relocate armadillos.
- Trap Selection: Use a live trap that is appropriately sized for an armadillo.
- Baiting: Armadillos are attracted to insects. Try using earthworms, mealworms, or grubs as bait. Place the bait at the back of the trap to ensure the armadillo is fully inside before the door closes.
- Placement: Place traps in areas where armadillo activity is highest, such as near burrows or frequently dug areas.
- Checking Traps: Check traps frequently, at least twice a day, to avoid stressing or harming the captured animal.
- Relocation: Relocate the armadillo to a suitable habitat far from residential areas. Check local wildlife regulations regarding trapping and relocating animals, as permits may be required.
2. Repelling Armadillos from Burrows
If an armadillo has already created a burrow on your property, direct armadillo burrow control methods can be employed.
- Flooding: In some cases, flooding a burrow with water from a hose can encourage the armadillo to leave. However, this may not always be effective and can be difficult in dry climates.
- Repellent Application: Some of the natural armadillo deterrents mentioned earlier can be applied directly into the burrow entrance.
- Blocking Burrows: Crucially, never seal off a burrow entrance if you suspect an armadillo is inside. They could be trapped, leading to their death and potential odor issues. Wait until you are certain the burrow is unoccupied. You can check by placing a loose soil barrier in the entrance – if it’s disturbed the next day, the armadillo is still using it. Once empty, you can then fill the burrow with soil or gravel.
3. Professional Help
If armadillo problems persist or you are uncomfortable with DIY methods, consider contacting a wildlife control professional. They have the expertise and tools for humane armadillo removal and can offer tailored solutions for your specific situation.
Long-Term Armadillo Yard Solutions
Sustainable armadillo yard solutions involve ongoing vigilance and consistent application of deterrents.
1. Regular Lawn Maintenance
- Mowing: Keep your lawn mowed to a reasonable height. Overgrown grass can provide cover for insects that armadillos feed on.
- Aeration: Aerating your lawn can improve soil health and drainage, potentially making it less attractive for burrowing.
2. Integrated Pest Management (IPM)
An IPM approach combines various methods to manage pests, including armadillos. This means:
- Monitoring: Regularly inspect your yard for signs of armadillo activity.
- Prevention: Employ habitat modification and physical barriers.
- Control: Use repellents and, as a last resort, humane trapping.
3. Understanding Local Wildlife
Familiarize yourself with local wildlife and their habits. Knowing when armadillos are most active and what attracts them to your specific area can help you plan your armadillo deterrence strategies more effectively.

Frequently Asked Questions (FAQ)
Q1: Can armadillos really hurt my foundation?
A1: While armadillos typically dig for insects, their burrowing activities can sometimes destabilize the soil near foundations, especially if burrows are extensive and close to the structure. It’s a good idea to monitor areas around your home for burrowing activity.
Q2: Are armadillos dangerous to pets?
A2: Armadillos are generally not aggressive towards pets and will usually try to escape if confronted. However, they can carry diseases like leprosy, so it’s advisable to keep pets from interacting with them or their burrows. Also, an armadillo might dig in areas where your pet buries bones, potentially creating a mess.
Q3: What is the best time of year to deal with armadillos?
A3: Armadillos are generally more active during warmer months. The spring is often a good time to implement armadillo deterrence strategies before they become heavily established. Dealing with them before they start their main burrowing and mating cycles can be more effective.
Q4: Can I use mothballs to repel armadillos?
A4: While some people try using mothballs, they are generally not recommended. Mothballs contain chemicals that can be harmful to children, pets, and the environment. Their effectiveness against armadillos is also questionable and often short-lived. Stick to safer and more proven armadillo repellent options.
Q5: How deep do armadillos dig their burrows?
A5: Armadillo burrows can vary in depth but are typically around 5-7 feet deep. They can also dig shallow foraging holes that are just a few inches deep. Their main burrows are designed for shelter and can be quite extensive with multiple entrances.
Q6: I’ve heard cayenne pepper is a good armadillo deterrent. Is it safe?
A6: Cayenne pepper and other hot spices are sometimes used as natural armadillo deterrents. While generally considered safe for the environment, they can be an irritant to the eyes and skin of both animals and humans. Their effectiveness is also limited as they can be easily washed away by rain or irrigation. It’s a temporary solution at best.
Q7: What if an armadillo is living under my shed? How do I get it out?
A7: The best approach for armadillo burrow control under a shed is to first confirm it’s unoccupied. You can do this by placing a loose barrier of soil or a few twigs in the entrance. If the barrier is disturbed overnight, the armadillo is still present. Once you’re sure it’s empty, seal the opening securely with sturdy mesh or concrete. Before sealing, you might try using an armadillo repellent to encourage it to leave the sheltered space.
Q8: Are there any plants that armadillos dislike?
A8: There isn’t a definitive list of plants that universally repel armadillos. Their primary interest is insects in the soil. However, some gardeners report that planting strongly scented plants like rue or castor bean plants (though castor bean is toxic) may have a minor deterring effect due to their strong aromas, potentially masking insect scents. Their effectiveness is not guaranteed.
By implementing a combination of these strategies, you can effectively manage armadillo activity and protect your yard from their persistent digging. Patience and persistence are key to successful armadillo damage control.
