Do armadillos dig holes in my yard? Yes, armadillos are known for their digging habits, which can cause unsightly holes and damage to lawns, gardens, and even structures. Can I deter armadillos from my yard? Absolutely! There are several effective methods and strategies you can employ to keep these burrowing mammals from becoming unwelcome guests.
Armadillos, with their unique bony armor and digging prowess, can turn a well-manicured yard into a minefield of tunnels and divots. Their primary motivation for digging is to find food, which consists mainly of insects, grubs, earthworms, and other invertebrates. If your yard is a buffet for these critters, you’re likely to see more of them. This guide will delve into comprehensive armadillo control methods, focusing on humane armadillo removal and armadillo proofing your property. We’ll explore various armadillo deterrents, repellents for armadillos, and the importance of creating barriers for armadillos to achieve effective armadillo exclusion.
Why Are Armadillos In My Yard?
The presence of armadillos in your yard is usually a sign that your yard offers them something they need. This typically boils down to two main factors: food and shelter.
Food Sources
Armadillos are insectivores. Their long, sticky tongues are perfect for lapping up ants, termites, beetles, grubs, earthworms, and other small creatures found in the soil. If your lawn or garden is rich in these tasty morsels, armadillos will see it as a prime dining destination. Overwatering can also bring earthworms closer to the surface, making them easier prey for armadillos.
Shelter and Habitat
Armadillos need places to burrow and create dens. They prefer moist, loose soil, often found under bushes, porches, sheds, or fallen logs. Areas with dense ground cover also provide ideal hiding spots. If your yard offers ample opportunities for creating burrows, or if there are existing structures they can utilize, they might decide to set up camp.
Effective Armadillo Deterrents
Dealing with armadillos requires a multi-pronged approach. The goal is to make your yard less appealing and less accessible to them. This involves a combination of making the environment inhospitable and physically preventing their entry.
The Power of Repellents for Armadillos
Repellents work by creating an odor or taste that armadillos find unpleasant, discouraging them from foraging or burrowing.
Natural Armadillo Repellents
Many gardeners and homeowners prefer natural armadillo repellents due to concerns about chemicals. These often utilize strong scents or irritating substances.
- Castor Oil: A widely recommended natural repellent. When applied to the soil or sprayed as a solution, the strong scent and taste are offensive to armadillos. You can mix castor oil with water and a bit of liquid soap to help it adhere to surfaces and then spray it around affected areas. Reapplication is usually needed after rain.
- Garlic and Onion: The pungent smell of garlic and onions is a strong deterrent. You can plant garlic and onions around the perimeter of your garden or create a spray by blending them with water and a bit of soap.
- Cayenne Pepper/Red Pepper Flakes: Armadillos dislike the burning sensation caused by capsaicin. Sprinkle cayenne pepper or red pepper flakes liberally around your garden beds and burrow entrances. Be cautious when applying as it can irritate your skin and eyes.
- Ammonia: The strong smell of ammonia can be effective. Soak rags in ammonia and place them strategically around your yard, especially near burrow entrances. Ensure pets and children cannot access these.
- Mothballs: While controversial due to potential toxicity to pets and children, mothballs are often cited as a repellent. The strong odor can deter armadillos. However, their use should be approached with caution, and it’s essential to follow product instructions and consider safer alternatives.
Commercial Repellents
Several commercial repellents for armadillos are available, often containing ingredients like castor oil, urea, or essential oils. When choosing a commercial product, look for those specifically labeled for armadillos and follow the application instructions carefully.
Creating Barriers for Armadillos
Physical barriers are one of the most effective ways to prevent armadillos from entering your yard or garden. This falls under the umbrella of armadillo proofing.
Fencing
A sturdy fence is a significant deterrent. However, armadillos are good diggers, so a standard fence might not be enough.
- Height and Depth: The fence should be at least 18-24 inches high to prevent them from easily climbing over. More importantly, it needs to extend into the ground. Burying the bottom of the fence at least 6-12 inches deep will discourage them from digging underneath.
- Material: Woven wire or hardware cloth is ideal as it’s strong and has small openings that prevent burrowing. Avoid chain-link fences as they are easier to dig under.
- Angle: Consider angling the bottom of the fence outwards (away from the yard) by about 6 inches. This makes it more difficult for them to get a foothold to dig under.
Solid Barriers
Solid barriers can also be effective in armadillo exclusion.
- Foundation Skirting: If armadillos are burrowing under sheds, decks, or porches, consider installing solid skirting. This should be made of sturdy material like metal sheeting or heavy-duty plastic, buried a few inches into the ground.
- Landscape Edging: For garden beds, use sturdy landscape edging materials that are buried sufficiently deep.
Modifying the Environment
Making your yard less attractive can be a powerful long-term strategy.
Food Source Reduction
- Reduce Insect Populations: Implementing integrated pest management (IPM) strategies can help reduce the insect and grub population that attracts armadillos. This might involve aerating your lawn, reducing excessive watering, and using natural pest control methods. Avoid over-fertilizing, which can encourage grubs.
- Clear Debris: Remove potential hiding places and food sources like woodpiles, leaf litter, fallen fruit, and compost heaps from the immediate vicinity of your home and garden.
Shelter Elimination
- Seal Entry Points: Regularly inspect structures like sheds, decks, and porches for existing or potential burrow entrances. Seal any holes or gaps with concrete, wire mesh, or sturdy materials.
- Fill Existing Burrows: Once you confirm the armadillo has left a burrow (often at night), fill it in completely with soil and rocks. This discourages them from returning to the same spot and prevents other wildlife from using it.
Humane Armadillo Removal and Exclusion Techniques
While deterrence is ideal, sometimes you need to address an existing problem. Humane armadillo removal focuses on relocating the animal without causing harm.
Live Trapping
Live trapping is a common method for humane armadillo removal.
Choosing a Trap
- Size: Select a trap that is large enough to accommodate an armadillo comfortably. A trap measuring around 10x12x32 inches is generally suitable.
- Type: A humane live trap with a single-door trigger mechanism is best. Ensure the trap has a solid bottom to prevent the armadillo from digging out.
Baiting the Trap
- Effective Baits: Armadillos are attracted to insects and grubs. You can use live earthworms, canned sardines, or a mixture of peanut butter and oatmeal as bait. Place the bait at the back of the trap, past the trigger plate.
- Placement: Place the trap in an area where you frequently see armadillo activity or near their burrows.
Trapping Tips for Safe Armadillo Removal
- Check Regularly: Check the trap frequently, at least twice a day, to avoid stressing the trapped animal and to ensure it’s a humane process.
- Handling: Once trapped, cover the trap with a blanket to calm the armadillo. Wear thick gloves when handling the trap to avoid being bitten.
- Relocation: Relocate the armadillo to a suitable habitat at least 5-10 miles away from your property. Ensure the new location has appropriate food and shelter but is far enough away that it won’t return. Check local regulations regarding wildlife relocation, as some areas have specific rules.
Exclusion Devices
Armadillo exclusion can also involve using one-way doors or exclusion funnels.
- How They Work: These devices are installed over burrow entrances or access points. They allow the armadillo to exit but prevent it from re-entering.
- Installation: Once installed, monitor the area for a few days to ensure the armadillo has left. After confirming, remove the device and permanently seal the entrance.

Understanding Armadillo Behavior for Better Control
To effectively implement armadillo control methods, it helps to grasp their typical behaviors.
Nocturnal Habits
Armadillos are primarily nocturnal, meaning they are most active at dawn and dusk, and throughout the night. This is when they forage for food. Daytime is usually spent in their burrows. This knowledge is crucial for effective trapping and for carrying out deterrent tasks when they are less likely to be active.
Digging Patterns
Their digging is driven by the search for food. They use their strong claws to excavate tunnels, often following scent trails of insects. Their digging can create extensive tunnel systems, sometimes even impacting shallow-rooted plants or undermining small structures.
Senses
Armadillos have poor eyesight but a highly developed sense of smell and hearing. This is why strong odors and vibrations can be effective deterrents.
