Wondering how to keep an armadillo out of your yard? While you can’t trap them without proper permits, you can make your yard less appealing to these armored visitors. Armadillos are often attracted to yards with plentiful food sources like insects, grubs, and earthworms, and soft, loose soil perfect for digging. If you’re finding tunnels and disturbed flowerbeds, it’s time to implement some armadillo control tips.
Why Armadillos Visit Your Yard
Armadillos, particularly the nine-banded armadillo, are nature’s excavators. They are on a constant search for food, which primarily consists of insects, grubs, earthworms, and other invertebrates found in the soil. Your yard might be a buffet if it’s rich in these critters. They also seek out moist, soft soil for burrowing and nesting. A well-irrigated lawn, especially one with grub infestations, can be a dream come true for an armadillo.
Common Attractions for Armadillos:
- Food Sources: Grubs, beetles, ants, termites, earthworms, slugs, snails, and other small invertebrates.
- Soil Conditions: Loose, moist soil that is easy to dig. Lawns, gardens, and compost piles are prime targets.
- Shelter: Dense vegetation, woodpiles, under decks, sheds, or any protected, undisturbed areas for creating burrows.
- Water: Access to water sources like ponds, puddles, or leaky faucets.
Effective Armadillo Deterrents
Discouraging armadillos involves making your yard an unappealing place for them to forage and burrow. This can be achieved through various methods, focusing on removing attractants and employing deterrents.
Making Your Yard Less Appetizing
The most effective way to keep armadillos away is to eliminate what draws them in. This means addressing your lawn and garden’s ecosystem.
1. Grub Control is Key
Grubs are a major food source for armadillos. Reducing the grub population in your lawn can significantly discourage them.
- Beneficial Nematodes: These microscopic worms are natural predators of grubs. Apply them to your lawn according to package directions, usually when soil temperatures are between 55-85°F (13-29°C).
- Milky Spore Disease: This naturally occurring bacterium targets Japanese beetle grubs. It takes a few years to become fully effective but provides long-term control.
- Chemical Insecticides: Use these sparingly and as a last resort. Always choose products specifically labeled for grub control and follow application instructions precisely. Consider organic or biological options first.
2. Remove Other Food Sources
- Clean Up Debris: Remove fallen fruit, pet food left outdoors, and any other potential food scraps that might attract insects, which in turn attract armadillos.
- Seal Compost Piles: Ensure your compost bins are secure to prevent armadillos from accessing discarded food scraps.
3. Eliminate Shelter Opportunities
Armadillos need safe places to rest and breed. Minimizing these can make your yard less inviting.
- Clear Dense Vegetation: Overgrown areas provide hiding places. Keep your lawn mowed and trim back dense shrubbery.
- Secure Outdoor Structures: Block off access to areas under decks, porches, sheds, and woodpiles with sturdy materials. This is a crucial step in armadillo proofing garden areas.
Employing Sensory Deterrents
Armadillos rely on their senses of smell and touch. Using substances that disrupt these senses can deter them.
1. Natural Armadillo Repellent Options
Several natural substances can make your yard less appealing to armadillos without causing harm. These are often based on strong smells or tastes that armadillos dislike.
- Castor Oil: This is a popular and generally effective natural armadillo repellent. Armadillos dislike the taste and texture of castor oil.
- How to Apply: Mix castor oil with water and a little liquid dish soap (to help it emulsure). Spray this mixture liberally around the perimeter of your yard, flowerbeds, and any areas where armadillos have been active. Reapply after rain. You can also soak rags in castor oil and place them in strategic locations.
- Cayenne Pepper/Chili Powder: The heat from capsaicin can be very irritating to an armadillo’s sensitive nose and feet.
- How to Apply: Sprinkle cayenne pepper or chili powder generously around your yard, especially near burrows or entry points. Be aware that heavy rain will wash it away, requiring frequent reapplication. It can also be mixed with water and sprayed, but direct application is often more potent.
- Garlic: The strong smell of garlic can be off-putting to armadillos.
- How to Apply: Plant garlic bulbs around the perimeter of your garden or sprinkle minced garlic or garlic powder in affected areas. Garlic sprays can also be made by blending garlic cloves with water and straining.
- Essential Oils: Certain essential oils, such as peppermint, eucalyptus, and tea tree oil, have strong scents that can deter armadillos.
- How to Apply: Mix a few drops of these oils with water and a carrier substance like rubbing alcohol or dish soap. Spray around the yard. Remember to reapply regularly.
2. Commercial Repellents
There are various commercial repellents available. Look for products that are specifically designed for armadillos or general burrowing animals. Many of these rely on strong odors or tastes. Always read and follow the product instructions carefully.
Physical Barriers: Armadillo Fence Installation
One of the most effective long-term solutions is to physically block armadillos from accessing your yard. This is where armadillo fence installation comes into play.
1. What Makes a Good Armadillo Fence?
An effective armadillo fence needs to be sturdy and have features that prevent them from digging under or climbing over.
- Height: The fence should be at least 18-24 inches tall.
- Material: Sturdy materials like hardware cloth, chicken wire (though less durable), or solid fencing materials are suitable.
- Burrow Prevention: This is the most critical aspect. Armadillos are excellent diggers. To prevent them from tunneling underneath, the fence needs to be buried.
- Burial Depth: Bury the bottom edge of the fence at least 10-12 inches into the ground.
- Outward L-Shape: For maximum protection, create an “L” shape at the bottom of the fence, with the flap extending outwards underground for at least 6 inches. This forces the armadillo to dig into the ground rather than under the fence.
2. DIY vs. Professional Installation
- DIY: If you’re handy, armadillo fence installation can be a cost-effective option. You’ll need materials like fence posts, wire mesh (hardware cloth is recommended for its strength), wire cutters, a shovel, and fasteners. The process involves digging a trench, setting posts, attaching the wire mesh, and burying the bottom section.
- Professional: Hiring a professional landscaper or fencing company can save you time and ensure the fence is installed correctly. They have the equipment and expertise to create an effective barrier.
3. Other Physical Barriers
- Netting: For specific garden beds, you can use heavy-duty garden netting buried around the edges to stop armadillos digging. This is a more localized solution.
- Solid Materials: Consider using concrete pavers or rocks around garden beds if they are particularly attractive to armadillos.
Humane Armadillo Removal and Exclusion Methods
While making your yard less hospitable is key, sometimes you need to address existing problems. Humane armadillo removal focuses on encouraging them to leave and preventing their return without causing harm.
Encouraging Them to Leave
- Water Hazards: Armadillos are not strong swimmers. A gentle, continuous stream of water from a hose directed at a burrow entrance might encourage them to relocate. However, this should be used cautiously and only if you can observe the effect without disturbing them excessively.
- Noise and Light: While not a guaranteed method, some people report success by placing bright lights or noisy devices (like radios) near burrow sites. Armadillos are primarily nocturnal and prefer quiet, dark environments.
Armadillo Exclusion Methods
Once you’ve deterred them or dealt with an existing burrow, armadillo exclusion methods are about preventing re-entry.
- Seal Burrows: After an armadillo has left a burrow (which you can sometimes tell by lack of activity for a few days), fill the burrow with soil, gravel, or sand. This prevents them from returning or new ones from taking up residence.
- Fill Holes: Regularly fill any small holes or disturbed soil areas in your yard. The less disturbed the soil, the less attractive it is for foraging.
- Maintain Fences: If you have an armadillo fence installation, regularly check it for any damage or gaps where they might try to get in.
Preventing Armadillo Damage
The primary damage armadillos cause is through their digging. They create shallow holes and deeper burrows when searching for food or creating nests. This can disrupt lawns, gardens, and even foundations.
Protecting Your Lawn and Garden
- Fill Holes Promptly: As mentioned, filling any new holes immediately is crucial. This discourages them from returning to the same spots and prevents larger burrow systems from developing.
- Improve Soil Drainage: While armadillos like moisture, overly saturated soil can be more easily disturbed. Improving soil drainage might make it less appealing.
- Elevated Gardens: Raised garden beds can make it more difficult for armadillos to access your plants and soil.
Protecting Structures
- Foundation Sealing: Ensure there are no easy entry points under decks, porches, or sheds. Seal any gaps or openings with sturdy materials.
- Clear Under Structures: Keep the areas under decks and sheds clear of debris and dense vegetation, which armadillos use for shelter.
