Why Armadillos Dig
Before we explore how to get rid of them, it’s helpful to understand why armadillos dig in the first place. Their primary motivation is foraging for food. Their diet consists almost exclusively of insects, worms, and other small invertebrates found in the soil. They have a keen sense of smell and can detect prey beneath the surface. Once they locate a food source, they dig with remarkable speed and efficiency.
Besides foraging, armadillos also dig to create burrows for shelter. These burrows provide protection from predators and the elements, serving as safe havens for resting and raising young. A single armadillo may have multiple burrows within its territory.
Identifying Armadillo Damage
Recognizing the signs of armadillo activity is the first step in addressing the problem. Armadillo digging typically results in:
- Shallow, conical holes: These are often found in lawns, flowerbeds, and gardens where insects are abundant. They can range in size from a few inches to over a foot deep.
- Upturned sod: In their quest for insects, armadillos can flip over sections of your lawn, leaving patches of torn-up turf.
- Damaged roots: While not their primary target, armadillos can inadvertently disturb plant roots during their digging.
- Burrows: Larger, more substantial holes indicate the presence of a burrow. These are typically found along foundations, under sheds, decks, or dense vegetation.
Effective Armadillo Control Methods
Dealing with armadillos requires a multi-pronged approach. The goal is to make your yard less attractive to them and to prevent them from accessing areas they shouldn’t be.
1. Habitat Modification: Making Your Yard Less Appealing
Armadillos are drawn to yards that offer abundant food and shelter. By modifying your yard’s environment, you can discourage them from making it their home.
Reducing Food Sources
- Treat for grubs and insects: The most effective way to deter armadillos is to eliminate their primary food source – insects. Regularly inspect your lawn and garden for grub infestations. Use insecticidal treatments specifically designed for lawn pests. Applying beneficial nematodes can also be a natural and effective way to control grubs.
- Clean up debris: Armadillos often seek shelter and forage in leaf litter, woodpiles, and overgrown vegetation. Keeping your yard tidy by removing these attractants can significantly reduce their appeal.
- Limit outdoor lighting: While not directly related to food, excessive outdoor lighting can attract insects, which in turn attract armadillos. Consider using motion-sensor lights or dimmer bulbs.
Eliminating Shelter
- Seal off potential harborage areas: Armadillos are opportunistic when it comes to shelter. They will readily utilize spaces under sheds, decks, porches, and other structures. Seal any openings leading to these areas. Use sturdy wire mesh or hardware cloth for this purpose.
- Fill in existing burrows: If you find an abandoned burrow, fill it in with soil and rocks. This discourages them from returning or using it as a base for new activity.
2. Physical Barriers and Exclusion
Physical barriers are a highly effective way to prevent armadillos digging in specific areas or to keep them out of your yard altogether.
Fencing
- Install an armadillo-proof fence: The most robust method is to install a fence specifically designed to deter armadillos. The fence should be at least 18 inches tall and buried at least 6 inches into the ground.
- Use sturdy material: Chain-link fencing, welded wire, or hardware cloth are good options. The mesh size should be no larger than 1 inch.
- Incorporate an inward bend: To prevent them from digging under, bend the bottom 6 inches of the fence outward at a 90-degree angle and bury it. This creates an “L” shape underground, making it difficult for them to tunnel beneath.
Burying Wire Mesh
- Protect vulnerable areas: For specific garden beds or flower patches that you want to protect, you can bury wire mesh just below the soil surface. This creates a subsurface barrier that discourages digging.
3. Repellents: Discouraging Armadillos
While not always a foolproof solution, armadillo repellent products can be a useful part of an integrated pest management strategy.
Chemical Repellents
- Castor oil-based repellents: These are common and generally considered effective. Castor oil irritates the armadillo’s digestive system if ingested, making treated areas unpalatable. They are typically applied as granules or liquid sprays.
- Other repellent ingredients: Some products contain essential oils like peppermint or predator urine (fox, coyote). The effectiveness of these can vary.
Natural Armadillo Deterrents
- Pepper-based repellents: Cayenne pepper or hot pepper flakes can be sprinkled around areas you want to protect. Armadillos may find the irritant unpleasant. However, these need frequent reapplication, especially after rain.
- Garlic and onion spray: A homemade spray of garlic and onion blended with water can also act as a deterrent due to their strong odor.
Important Considerations for Repellents:
- Reapplication is key: Repellents, especially natural ones, lose effectiveness over time due to weather and dilution. Consistent reapplication is crucial.
- Targeted application: Apply repellents directly to areas where armadillos are digging or where you want to prevent them from digging.
- Safety: Always follow the product instructions carefully, especially regarding pets and children.
4. Trapping: Humane Armadillo Removal
For persistent problems or when other methods haven’t worked, humane armadillo traps offer a way to remove animals from your property.
Types of Humane Traps
- Live traps: These are cage-like devices that capture the armadillo without harming it. They are typically baited with earthworms, grubs, or fruit.
- Size matters: Ensure the trap is large enough to accommodate an armadillo comfortably. A common size is around 10 inches wide by 12 inches high by 30 inches long.
Trapping Strategies
- Placement: Place traps along known armadillo travel paths, near burrows, or in areas of recent digging.
- Baiting: Use attractive baits like mealworms, earthworms, or pieces of fruit. Place the bait at the back of the trap to ensure the armadillo triggers the mechanism.
- Check traps frequently: It is crucial to check live traps at least twice a day (morning and evening) to prevent the animal from becoming stressed, dehydrated, or exposed to extreme weather.
Relocation
- Local regulations: Before relocating an armadillo, check your local wildlife regulations. Some areas have specific rules about trapping and relocating wildlife.
- Suitable habitat: Relocate the armadillo to a suitable habitat far from residential areas, preferably a natural environment with a good food and water supply. A minimum of 10-20 miles away is often recommended to prevent them from returning.
When considering trapping, remember that removing one armadillo may simply open up the territory for another to move in if the underlying attractants (food, shelter) are not addressed.
5. Armadillo Burrow Control
Burrowing can cause significant structural damage. Armadillo burrow control focuses on both managing active burrows and preventing new ones.
Filling Existing Burrows
- Immediate filling: As soon as you identify an active or inactive burrow, fill it with soil, gravel, or rocks. Compact the material tightly.
- Reinforcement: For burrows near foundations, consider reinforcing the area with concrete or sturdy mesh after filling.
Deterring Burrow Construction
- Soil compaction: Heavily compacted soil is less appealing for burrowing. This can be achieved through regular gardening practices and avoiding excessive tilling.
- Subsurface barriers: As mentioned earlier, burying wire mesh can prevent burrowing in specific garden beds.
6. Armadillo Damage Repair
Once you’ve managed the armadillo activity, you’ll likely need to address the resulting armadillo damage repair.
- Repairing lawn damage: For torn-up sod, gently press the turf back into place and water it thoroughly. You may need to add topsoil and reseed bare patches.
- Filling holes: Fill smaller digging holes with soil and compact it. For larger holes, a mixture of soil and gravel can be used.
- Restoring flowerbeds: Carefully examine plants for root damage and replant or provide support as needed. Replace any lost mulch or soil.
What Eats Armadillos?
While armadillos have a tough exterior, they are not without natural predators. Knowing what eats armadillos can offer some context, though it’s rarely a practical solution for homeowners.
- Coyotes: These opportunistic predators are a significant threat to armadillos, especially younger ones.
- Bobcats: Similar to coyotes, bobcats will prey on armadillos when the opportunity arises.
- Alligators: In areas where their habitats overlap, alligators can be a predator.
- Birds of prey: Larger birds of prey, like eagles or great horned owls, may occasionally take young or weakened armadillos.
- Domestic dogs and cats: While less common and often resulting in injury to the pet, some domestic animals might attempt to hunt armadillos.
It’s important to note that relying on natural predators to control armadillo populations in a residential setting is generally not feasible or desirable.
Best Armadillo Removal Strategies: A Summary
The best armadillo removal approach is one that is tailored to your specific situation and combines multiple methods. Here’s a general strategy:
- Assessment: Identify the extent of the problem – how many holes, where are they located, are there active burrows?
- Deterrence (Prevention First):
- Reduce insect populations in your yard.
- Eliminate potential shelter areas.
- Consider using natural armadillo deterrents or armadillo repellent products.

- Relocate captured animals responsibly according to local laws.
- Repair: Once the armadillos are gone, address any armadillo damage repair needed for your lawn and garden.
- Ongoing Maintenance: Continue habitat modification and barrier checks to prevent armadillos digging in the future.
Frequently Asked Questions About Armadillos
Q1: Are armadillos dangerous?
Armadillos are generally not dangerous to humans or pets. They are shy creatures and will typically try to escape rather than confront. Their primary defense mechanism is to retreat into their burrows or curl into a ball (though only the three-banded armadillo species can do this effectively). They do not carry leprosy that can infect humans, although they are one of the few animals that can contract the disease.
Q2: How can I make my yard less attractive to armadillos?
You can make your yard less attractive by reducing their food sources (insects like grubs), eliminating shelter (clearing debris, sealing off areas under structures), and using repellents.
Q3: Can I just kill the armadillos?
While lethal methods exist, they are often not the most effective long-term solution and can be inhumane. Furthermore, many areas have regulations against killing wildlife. Humane removal and deterrence are generally preferred and more sustainable.
Q4: What is the most effective armadillo repellent?
The most effective armadillo repellent is often one that is consistently applied and targets their food source. Castor oil-based repellents are widely recognized for their effectiveness. However, combining repellents with habitat modification and exclusion offers the best chance of success.
Q5: How deep do armadillos dig their burrows?
Armadillo burrows can vary in depth, but they typically range from 5 to 15 feet long and can be 1 to 4 feet deep. Some can be much more extensive.
Q6: Can I fill in an armadillo burrow that is under my house?
Yes, it is crucial to address any burrows found under structures. If an armadillo is actively using the burrow, you must ensure it is no longer present before filling it. You can try to coax it out with a repellent or by making noise, or by trapping it. Once you are certain the burrow is empty, fill it completely with soil and gravel. If the burrow is extensive or poses a significant structural risk, consult a pest control professional or a foundation specialist.
Q7: What are the best natural armadillo deterrents?
Natural armadillo deterrents include substances like cayenne pepper, garlic, onions, and essential oils that create an unpleasant sensory experience for the animals. However, their effectiveness can be limited by weather conditions, requiring frequent reapplication.
By implementing these expert tips, you can effectively manage and deter armadillos from digging in your yard, protecting your landscape and restoring peace to your outdoor spaces. Remember that consistency and a combination of methods are key to successful armadillo control.
