Why Are Armadillos Digging in My Yard?
Before we can effectively deter armadillos, it’s helpful to understand what draws them to your yard in the first place. These solitary, nocturnal creatures are driven by one primary need: food.
- Insects and Grubs: Their diet consists mainly of insects, grubs, worms, spiders, and other invertebrates. If your soil is rich with these tasty morsels, it’s like an all-you-can-eat buffet for an armadillo.
- Moist Soil: Armadillos often prefer moist soil, which can be found in well-watered lawns, gardens, and areas with leaky hoses or irrigation systems.
- Shelter: They also look for safe places to burrow and sleep. Areas with dense vegetation, overgrown brush, or debris piles offer ideal conditions for creating burrows.
- Leaf Litter: Piles of leaves or mulch can harbor insects, making them attractive foraging grounds.
Effective Strategies to Keep Armadillos Out
Keeping armadillos at bay requires a proactive and consistent approach. It’s about making your yard unappealing and inaccessible.
1. Creating Physical Barriers: The Armadillo Fence
Perhaps the most effective long-term solution is to construct a physical barrier. An armadillo fence is designed to prevent them from entering your yard. However, not just any fence will do.
Key Features of an Effective Armadillo Fence:
- Height: Armadillos can climb short distances, but a fence around 2-3 feet high is generally sufficient.
- Depth: This is crucial. Armadillos are excellent diggers. To stop armadillos, your fence needs to extend into the ground. Burying the bottom edge of the fence at least 12 inches deep is recommended.
- Material: Sturdy materials like hardware cloth (galvanized steel mesh with small openings, usually 1/2 inch or 1/4 inch), solid metal sheeting, or sturdy vinyl fencing can work well. Avoid materials they can easily push through or dig under.
- Angling: For maximum effectiveness, consider angling the bottom portion of the fence outwards (away from your yard) by about 6 inches. This makes it harder for them to get a foothold to dig underneath. Burying it at this outward angle is even better.
Example of a DIY Armadillo Fence Structure
| Component | Material | Depth/Height | Purpose |
|---|---|---|---|
| Main Fence | 1/2-inch Hardware Cloth or Sheet Metal | 2-3 feet | Physical barrier against entry |
| Buried Base | Hardware Cloth or Sheet Metal | 12 inches minimum | Prevents digging underneath |
| Outward Angle | Hardware Cloth or Sheet Metal | 6 inches | Discourages burrowing under the fence |
| Posts | Metal T-posts or sturdy wooden stakes | 3-4 feet above ground | To support and hold the fence upright |
| Fasteners | Heavy-duty zip ties or wire | Securely attach mesh to posts | To ensure the fence is taut and secure |
Installation Tips for Your Armadillo Barrier:
- Mark the Perimeter: Plan where you want to install the fence.
- Dig a Trench: Dig a trench along the planned perimeter to the required depth (at least 12 inches).
- Install Posts: Set the posts firmly in the ground to support the fence.
- Attach Mesh: Securely attach the hardware cloth or metal sheeting to the posts, ensuring it extends into the trench. Remember to angle the bottom portion outward if possible.
- Backfill Trench: Backfill the trench with soil, ensuring the buried portion of the fence remains secure.
- Check for Gaps: Walk along the entire length of the fence to ensure there are no gaps or weak points.
This robust armadillo barrier will be your most reliable defense against their digging activities.
2. Reducing Food Sources: Starve Them Out (Gently)
If your yard is a prime feeding ground, reducing the available food will make it less attractive.
Simple Steps to Reduce Armadillo Food:
- Limit Lawn Grubs: Apply grub control treatments to your lawn. Organic options are available if you prefer to avoid chemicals.
- Clear Debris: Remove leaf litter, woodpiles, and other debris where insects and grubs like to hide.
- Control Overwatering: Avoid overwatering your lawn and garden, as armadillos prefer moist soil. Ensure your irrigation systems are efficient.
- Secure Trash Cans: If you have outdoor trash, make sure the cans are sealed tightly. While not their primary food source, they might investigate for spilled scraps.
3. Habitat Modification: Making Your Yard Less Inviting
Armadillos look for shelter. By removing potential hiding spots, you make your yard less appealing.
Modifying Your Yard for Armadillo Deterrence:
- Trim Overgrowth: Keep grass mowed and trim back dense shrubbery or overgrown areas.
- Remove Piles: Get rid of any piles of leaves, grass clippings, brush, or lumber. These are prime real estate for armadillo burrows.
- Fill Old Burrows: If you find existing burrows (often around foundations, under sheds, or in dense ground cover), fill them in with soil. Armadillos may reuse abandoned burrows, so filling them discourages their presence.
4. Employing Armadillo Repellent: Natural and Humane Options
While chemical repellents are often harsh, there are natural armadillo repellent options that can help deter armadillos. These often work by making the scent or taste of your yard unpleasant.
Natural Repellents to Try:
- Castor Oil: A mixture of castor oil and water sprayed on the lawn can be effective. Castor oil is thought to make the soil and the insects within it unpalatable. Mix about 2-3 tablespoons of castor oil with a gallon of water. You might also add a squirt of liquid dish soap to help emulsify the oil. Reapply after rain or heavy watering.
- Cayenne Pepper/Chili Powder: Some people find success by sprinkling cayenne pepper or chili powder around the perimeter of their yard or in areas where armadillos are active. The idea is that the spicy irritant will deter them. However, this needs frequent reapplication and can be washed away by rain or irrigation. Be cautious with this method if you have pets or children who might come into contact with it.
- Essential Oils: Certain strong-smelling essential oils, like peppermint, eucalyptus, or citronella, are sometimes used. Mix a few drops with water and spray. Like cayenne, their effectiveness is often temporary and requires frequent reapplication.
Effectiveness of Natural Repellents
| Repellent Type | How it Works | Application Frequency | Potential Drawbacks |
|---|---|---|---|
| Castor Oil | Makes soil/insects unpalatable | Every 2-4 weeks | Can be washed away, may require large quantities |
| Cayenne Pepper | Irritant | Frequent (after rain) | Washes away easily, potential harm to pets/kids |
| Essential Oils | Strong scent deterrents | Frequent (after rain) | Temporary effect, can be costly for large areas |
It’s important to note that the efficacy of natural repellents can vary greatly. Persistence and frequent reapplication are key.
5. Ultrasonic Devices: A Technological Approach
Ultrasonic devices emit high-frequency sounds that are inaudible to humans but are supposed to be annoying to certain animals, including armadillos.
Considerations for Ultrasonic Devices:
- Effectiveness: Research on the effectiveness of these devices for armadillos is mixed. Some users report success, while others find them ineffective.
- Range: The effective range of these devices can be limited, and the sound may not penetrate dense vegetation or reach all areas of your yard.
- Battery/Power: Ensure the devices are adequately powered and placed strategically.
6. Lively Yard Management: Discouraging Their Activity
A well-maintained yard can be a deterrent in itself.
Proactive Yard Maintenance for Armadillo Control:
- Regular Mowing: Keep your lawn mowed to a reasonable height. Long grass can harbor insects and provide cover.
- Aerate Your Lawn: Aerating your lawn improves drainage and can make the soil less attractive to armadillos looking for moist digging conditions.
- Fill Holes Promptly: As soon as you notice digging, fill the holes with soil. This discourages further digging in the same spots.
Humane Armadillo Removal: When Other Methods Fail
If armadillos are already established and causing significant damage, you might consider humane armadillo removal. This typically involves trapping and relocating them.
Trapping and Relocation:
- Live Traps: Use a live trap designed for medium-sized mammals. Place it in an area where you’ve seen armadillo activity.
- Baiting: Use attractive baits like earthworms, grubs, or canned sardines inside the trap.
- Check Traps Regularly: It is crucial to check traps at least twice a day, especially during hot or cold weather, to ensure the animal is not stressed, injured, or dehydrated.
- Relocation: Once an armadillo is caught, relocate it to a suitable habitat far from human residences. Check your local wildlife regulations regarding trapping and relocating animals, as there may be specific rules or permits required. Relocation can sometimes be problematic as it might displace the animal from a territory it knows and could expose it to new dangers.
7. Armadillo Exclusion: Sealing Off Entry Points
This is a crucial part of armadillo proofing, especially for structures like sheds, decks, or crawl spaces.
How to Perform Armadillo Exclusion:
- Inspect Thoroughly: Examine the perimeter of your house, deck, shed, or any other structure for gaps or openings where an armadillo might burrow or enter. Look for areas around foundations, pipes, vents, or any loose skirting.
- Seal Openings: Seal all identified openings with sturdy materials. Options include:
- Hardware Cloth: Use heavy-gauge hardware cloth (1/2-inch mesh or smaller) to cover vents or openings.
- Metal Flashing: Use sheet metal or metal flashing to secure areas around foundations or pipes.
- Concrete: For larger gaps or burrow entrances near foundations, consider filling them with concrete.
- Bury Skirting: If you have skirting around decks or patios, ensure it extends at least 12 inches into the ground and is made of a material armadillos cannot easily dig through. Burying the bottom edge of the skirting outward at an angle is a good practice.
Common Areas for Armadillo Exclusion
| Structure Type | Potential Entry Points | Recommended Exclusion Material | Installation Tip |
|---|---|---|---|
| House Foundation | Gaps around pipes, vents, corners, loose bricks, damaged mortar | Hardware cloth, metal flashing, concrete | Bury material 12 inches deep, angle outward |
| Decks/Patios | Gaps in skirting, openings beneath the structure | Hardware cloth, sturdy vinyl skirting, metal | Bury skirting 12 inches deep, secure all edges |
| Sheds/Outbuildings | Gaps in walls, under doors, around foundations | Hardware cloth, metal sheeting | Ensure no gaps are left, seal around all entrances |
| Flowerbeds | Open edges, areas near dense plantings | Low garden fencing with buried edge | Extend fencing 6-8 inches into the ground |
Frequently Asked Questions (FAQ)
Q1: Are armadillos dangerous to humans or pets?
Armadillos are generally not aggressive and pose little direct threat to humans or pets. They have poor eyesight and tend to flee from perceived danger. While they can carry salmonella, the risk of transmission is low if proper hygiene is maintained. Their primary danger is the damage they cause through digging.
Q2: What time of day are armadillos most active?
Armadillos are primarily nocturnal, meaning they are most active at night. However, they may also forage during dawn and dusk, and sometimes on overcast or cooler days.
Q3: How deep do armadillos dig their burrows?
Armadillo burrows can vary in depth, but the main entrances are typically about 7-8 inches in diameter and can extend several feet into the ground. They create multiple burrows for different purposes, including shelter and escape.
Q4: Will flooding my yard get rid of armadillos?
Flooding might temporarily drive armadillos out of their burrows, but it’s not a long-term solution. They are adept swimmers and can often find drier areas nearby. Moreover, excessive flooding can damage your lawn and plants.
Q5: Can I use lights or noise to deter armadillos?
While bright lights or sudden loud noises might startle them temporarily, armadillos can become accustomed to them. Consistent, persistent deterrents like physical barriers or habitat modification are generally more effective.
Q6: How do I know if I have armadillo damage or damage from another animal?
Armadillo digging typically creates shallow, cone-shaped holes or trenches in the soil, often in lawns, gardens, or flowerbeds, as they search for insects. They are the only native North American mammal with a bony shell, and their tracks are distinctive – often appearing as if a small, leathery pig has walked through your yard. Other animals like moles, voles, or raccoons create different types of damage.
Conclusion: A Comprehensive Approach to Armadillo-Free Living
