Armadillos can wreak havoc on your yard, leaving behind a trail of destruction. So, how do you get rid of armadillos in your yard? The most effective approach involves a combination of prevention, deterrence, and, if necessary, removal. This guide will walk you through everything you need to know to reclaim your lawn from these digging nuisérables.
Armadillos are fascinating creatures, but when they turn your prize-winning petunias into a minefield of divots or undermine your patio, they quickly become unwelcome guests. Their powerful claws are designed for digging, and they use them to unearth insects, grubs, and other invertebrates that form the bulk of their diet. Unfortunately for homeowners, this means extensive burrowing and tunneling, which can cause significant armadillo damage to gardens, lawns, and even foundations.
Why Armadillos Invade Your Yard
Before we dive into armadillo control, it’s helpful to understand why they choose your yard in the first place. Armadillos are primarily attracted to areas with ample food sources and suitable conditions for burrowing.
Food Availability
The primary draw for armadillos is food. They have a keen sense of smell and can locate insects and grubs up to six inches underground. Lawns with a healthy population of earthworms, beetles, ants, termites, and other invertebrates are prime targets. Over-watering can sometimes encourage insect populations, inadvertently creating an armadillo buffet.
Shelter and Burrowing Opportunities
Armadillos need safe places to shelter and breed. They create burrows in loose soil, under bushes, decks, sheds, or any other sheltered areas. They don’t typically hibernate, so they need these burrows year-round for protection from predators and extreme weather.
Habitat Preferences
Armadillos thrive in moist, sandy soil. They are most commonly found in the southeastern United States, but their range has been expanding. Areas with dense ground cover, leaf litter, and fallen logs provide both food and potential den sites.
Identifying Armadillo Damage
Recognizing armadillo activity is the first step in effective armadillo removal. The most obvious sign is the tell-tale digging patterns.
Shallow Digging (Foraging Holes)
These are small, cone-shaped holes, usually only a few inches deep. Armadillos dig these holes as they forage for insects. They tend to be scattered across the lawn and in garden beds.
Deeper Burrows
Armadillos dig larger burrows for shelter. These can be several feet long and may have multiple entrances. You might find these under structures, dense shrubs, or in undisturbed areas of your yard. The entrances are typically about 7-8 inches wide.
Undermined Gardens and Plants
Armadillos don’t usually eat plants, but their digging can uproot young plants, expose roots, and damage flowerbeds.
Damage to Infrastructure
In severe cases, armadillos can burrow under patios, walkways, or even house foundations, potentially compromising structural integrity. This kind of damage can be costly to repair.
Methods for Armadillo Removal and Deterrence
Now that you know why they’re there and what signs to look for, let’s explore how to get rid of armadillos in your yard. A multi-pronged strategy is usually the most effective.
1. Habitat Modification: Making Your Yard Less Appealing
The most sustainable way to deter armadillos is to make your yard less attractive to them. This involves addressing their food and shelter needs.
Reducing Insect and Grub Populations
- Proper Watering: Avoid over-watering your lawn, as this can increase insect populations. Water deeply but less frequently.
- Grub Control: Use beneficial nematodes or milky spore disease, which are natural ways to control grub populations without harming beneficial insects.
- Yard Cleanliness: Keep your yard free of leaf litter, fallen fruit, and debris where insects and grubs can hide and multiply. Compost piles should be managed carefully.
Eliminating Shelter
- Seal Entry Points: Block access to areas under decks, porches, sheds, and crawl spaces with sturdy wire mesh (like hardware cloth) or solid barriers. Ensure the mesh is buried at least 12 inches deep and extends 6 inches above ground to prevent them from digging under it.
- Remove Debris: Clear away brush piles, woodpiles, and other debris that armadillos might use for shelter.
- Mow Regularly: Keep your grass mowed to a shorter height. Armadillos prefer to forage in taller grass where insects are more prevalent.
2. Natural Armadillo Deterrents and Repellents
Many homeowners prefer natural armadillo deterrents to avoid harsh chemicals. While their effectiveness can vary, some have shown promise.
Scent-Based Repellents
Armadillos have a good sense of smell, and certain strong scents can be off-putting to them.
- Castor Oil: A mixture of castor oil and water sprayed on the lawn is often cited as an armadillo repellent. The idea is that it makes the soil unpalatable to them when they ingest it while digging.
- Ammonia: The smell of ammonia can be unpleasant for armadillos. Soaking rags in ammonia and placing them near burrows or frequently visited areas might help.
- Peppermint Oil: Strong scents like peppermint oil, mixed with water and sprayed around the perimeter of your yard, can also act as a deterrent.
- Cayenne Pepper/Chili Powder: Sprinkling these spices around the affected areas can irritate their noses and mouths, discouraging them from digging. Reapply after rain.
Sound and Vibration Repellents
- Ultrasonic Devices: These devices emit high-frequency sounds that are inaudible to humans but can be annoying to pests like armadillos. Placement and effectiveness can vary greatly.
- Wind Chimes/Noise Makers: Sudden noises can startle them, but armadillos can become accustomed to consistent sounds over time.
Physical Barriers
- Fencing: A sturdy fence is one of the most effective ways to armadillo proof your yard. The fence should be at least 18-24 inches high and buried at least 12 inches into the ground. Consider using wire mesh or solid metal to prevent them from digging under it. Ensure there are no gaps.
3. Armadillo Trapping: When All Else Fails
If other methods haven’t worked, armadillo trapping might be necessary for armadillo removal. However, it’s crucial to do this humanely and legally.
Live Trapping
- Types of Traps: Use a live trap designed for medium-sized mammals. A cage trap that triggers a door when the animal steps on a pressure plate is common.
- Baiting: Armadillos are attracted to insects, grubs, or earthworms. You can also try baiting with overripe fruit or canned cat food. Place the bait at the back of the trap so the animal has to step on the trigger plate.
- Placement: Place the trap along known travel paths or near burrows. Try to camouflage the trap with natural materials like leaves or branches.
- Checking Traps: Check the trap frequently, at least twice a day (morning and evening). Leaving an animal in a trap for extended periods can cause stress, dehydration, or starvation.
- Relocation: If you catch an armadillo, you must check your local wildlife regulations regarding trapping and relocation. Relocating an armadillo to a different area might be illegal or simply move the problem to someone else’s yard. Furthermore, relocated animals may struggle to adapt to a new environment and find food and shelter.
Lethal Trapping (Use with Caution and Check Regulations)
In some areas, lethal trapping methods may be permitted, but these should be a last resort and conducted with extreme care and adherence to all local laws and regulations. Professional wildlife control services are often the best option for implementing these methods.
4. Professional Armadillo Control Services
If you’re struggling to manage an armadillo infestation or are uncomfortable with trapping, consider hiring a professional wildlife removal service. They have the expertise and equipment to humanely and effectively handle armadillo removal and can offer advice on armadillo proofing your property.
Preventing Future Armadillo Problems
Once you’ve successfully removed armadillos from your yard, the key is to prevent them from returning.
Ongoing Maintenance
- Consistent Lawn Care: Continue with regular mowing and proper watering practices.
- Regular Inspections: Periodically check your yard for signs of new digging or burrowing activity.
- Maintain Barriers: Ensure any fences or barriers remain intact and free of gaps.
- Reduce Food Sources: Continue efforts to minimize insect and grub populations in your lawn and garden.
Understanding Armadillo Behavior
Knowing when armadillos are most active can help you implement preventative measures. They are primarily nocturnal or crepuscular (active at dawn and dusk). This means they are most likely to be active in your yard during these times.
What is the Best Way to Get Rid of Armadillos?
The best way to get rid of armadillos involves a comprehensive approach:
- Reduce Food Sources: Control insect and grub populations in your lawn.
- Eliminate Shelter: Block access to areas under decks, sheds, and remove debris piles.
- Use Deterrents: Employ natural repellents like castor oil or spicy powders.
- Install Barriers: Use fencing to create an armadillo proof yard.
- Trapping (if necessary): Use live traps as a last resort, following all regulations.
Can I Use Repellents to Deter Armadillos?
Yes, you can use repellents to deter armadillos. Natural repellents like castor oil, ammonia, peppermint oil, and cayenne pepper can be effective. For best results, apply them consistently and reapply after rain.
How to Stop Armadillos from Digging
To stop armadillos from digging, you need to remove what attracts them: food and shelter. Reduce insect populations in your soil and eliminate potential den sites by blocking access to sheltered areas under structures and clearing away debris. Physical barriers like fences are also very effective.
Common Armadillo Damage and Solutions
Let’s break down specific armadillo damage and how to address it:
Lawn Damage: The Divot Disaster
Problem: Armadillos create numerous small, shallow holes as they forage for grubs.
Solution:
* Grub Control: Use grub control products or natural methods like beneficial nematodes.
* Aerate Lawn: Aerating your lawn can improve drainage and soil health, making it less attractive to insects.
* Repellents: Apply castor oil-based repellents.
* Fill Holes: Once deterred, fill the holes with soil and reseed the affected areas.
Garden Damage: Uprooted and Disturbed
Problem: Armadillos can dig up plants, expose roots, and disrupt your carefully planned garden beds.
Solution:
* Plant Protection: Use wire mesh or netting around vulnerable plants.
* Raised Beds: Raised garden beds can sometimes be less appealing for digging.
* Repellents: Apply natural armadillo deterrents around the perimeter of your garden.
* Intensive Digging Control: If the damage is severe, consider armadillo trapping.
Structural Damage: Foundations and Foundations
Problem: Armadillos may burrow under sheds, decks, patios, or even house foundations.
Solution:
* Barrier Installation: This is critical. Install sturdy wire mesh (hardware cloth) at least 12 inches deep and 6 inches high around the perimeter of structures.
* Seal Entry Points: Permanently seal any existing holes or gaps leading under structures.
Natural Armadillo Deterrent Options in Detail
Let’s explore some of the most popular natural armadillo deterrents:
Castor Oil
- How it Works: Armadillos are thought to dislike the taste and texture of castor oil when it contaminates their food sources.
- Application: Mix 2 tablespoons of castor oil with 1 tablespoon of liquid dish soap (as an emulsifier) in a gallon of water. Spray liberally on lawns and garden areas.
- Reapplication: Needs to be reapplied every few weeks, especially after rain.
Spicy Sprays (Cayenne, Chili Powder)
- How it Works: The capsaicin in these spices irritates the armadillo’s sensitive nose and feet.
- Application: Sprinkle cayenne pepper or chili powder directly onto the soil around affected areas. Alternatively, create a spray with water and a generous amount of hot pepper sauce.
- Reapplication: Must be reapplied frequently, as it washes away easily.
Garlic and Onion Sprays
- How it Works: The strong smell of garlic and onions can be repulsive to armadillos.
- Application: Blend garlic cloves and onions with water, strain, and spray.
- Reapplication: Similar to pepper sprays, frequent reapplication is necessary.
Coffee Grounds
- How it Works: Some believe the caffeine and strong smell of used coffee grounds can deter armadillos.
- Application: Sprinkle used coffee grounds around garden beds.
- Effectiveness: This is generally considered a mild deterrent, but it also has the benefit of enriching the soil.
Ground Pepper and Essential Oils
- How it Works: Similar to cayenne, ground pepper irritates their senses. Essential oils like peppermint and eucalyptus can also be too strong for them.
- Application: Mix with water and a surfactant (like mild soap) and spray.
- Caution: Always test on a small area of your lawn first to ensure it doesn’t damage your grass.
Armadillo Proof Yard: The Ultimate Defense
Creating an armadillo proof yard involves a multi-layered approach focused on prevention and exclusion.
Key Elements of an Armadillo Proof Yard
- Sturdy Fencing: The most effective long-term solution. Install a fence made of hardware cloth or solid metal, at least 18-24 inches high, with at least 12 inches buried underground. Ensure the bottom edge is angled outward slightly or has an inward-facing skirt of mesh to prevent digging under.
- Eliminate Food Sources: Regularly address grub and insect infestations.
- Remove Shelter: Clear brush, woodpiles, and secure all areas under decks, sheds, and porches with buried mesh.
- Maintain Lawn Health: A healthy, dense lawn is less appealing to foraging armadillos than sparse, dry, or insect-ridden turf.
- Regular Monitoring: Be vigilant for any signs of new activity.
Frequently Asked Questions (FAQ)
Q1: Are armadillos dangerous to humans or pets?
While armadillos are generally not aggressive, they can bite if cornered or threatened. They can also carry diseases like leprosy, though the risk of transmission to humans is very low. Keep pets supervised when they are outdoors, especially if armadillos are present.
Q2: Can I use mothballs to repel armadillos?
Mothballs are often suggested, but they are generally not recommended for repelling wildlife. They contain naphthalene or paradichlorobenzene, which are toxic and can be harmful to pets, children, and the environment. Their effectiveness against armadillos is also questionable.
Q3: How deep do armadillos dig their burrows?
Armadillo burrows can range in depth. Foraging holes are usually only a few inches deep. However, their main shelter burrows can be up to 6 feet deep and several feet long, often with multiple entrances.
Q4: What is the best bait for armadillo trapping?
Common baits include earthworms, grubs, mealworms, overripe fruit, or canned cat food. Placing these at the back of a live trap, on the trigger plate, is essential for successful armadillo trapping.
Q5: Will freezing temperatures kill armadillos?
Armadillos are not well-adapted to extreme cold. While they can survive mild winters, prolonged or severe freezes can be lethal to them, especially if they cannot access food or adequate shelter. However, relying on natural cold to manage them is not a reliable armadillo control strategy.
Q6: How can I make my yard less attractive to armadillos naturally?
Focus on reducing their food sources by managing insect populations and eliminating potential shelter areas like brush piles and spaces under decks. Regular yard maintenance and maintaining a healthy lawn are key natural armadillo deterrents.
By implementing these strategies, you can effectively manage armadillo activity in your yard and transform it back into a pest-free zone. Remember that consistency and a thorough approach are crucial for successful armadillo control.
