Armadillos under decks often seek shelter and food, requiring exclusion methods to remove them. If you are wondering how to get rid of armadillos under deck, you need a plan that combines trapping, exclusion, and habitat modification. These nocturnal diggers can cause serious damage to your yard and foundation if left unchecked.
Armadillos are not aggressive, but they are persistent. They dig for grubs, worms, and insects, which is why they love the cool, damp space under your deck. The good news is you can solve this problem without harming the animal.
Let’s walk through the most effective steps. We will cover everything from identifying the problem to preventing future visits.
Understanding Why Armadillos Are Under Your Deck
Armadillos are solitary creatures that look for two things: food and shelter. Your deck provides both. The soil underneath stays moist and dark, which attracts insects and grubs—their main food source.
They also use the space as a den. Female armadillos may even give birth there. If you see small holes in your lawn that look like cones, those are armadillo feeding holes. They dig about 3 to 5 inches deep to reach larvae.
You might also notice larger burrows near the deck edges. These are their entry points. Armadillos are strong diggers, so they can easily tunnel under a deck if there is no barrier.
Signs Of Armadillo Activity
- Small, cone-shaped holes in your lawn (feeding holes)
- Larger burrows (10–15 inches wide) near the deck
- Uprooted plants or disturbed mulch
- Scratched or dug-up areas around the deck perimeter
- Strong musky odor if they have been living there for a while
If you see these signs, you likely have an armadillo living under your deck. Dont wait too long—they can multiply and cause more damage.
How To Get Rid Of Armadillos Under Deck
This is the core section of your plan. We will cover the most reliable methods. Remember, armadillos are wild animals, so patience and consistency are key.
Method 1: Live Trapping
Live trapping is the most effective way to remove an armadillo that is already under your deck. Use a cage trap that is at least 10x12x32 inches. Armadillos need room to move inside the trap.
Place the trap near the burrow entrance or along a fence line they use. Bait the trap with overripe fruit like bananas, or use earthworms and grubs. Armadillos have a poor sense of sight but a good sense of smell, so fresh bait works best.
Set the trap in the evening. Check it early in the morning. If you catch an armadillo, wear thick gloves when handling the trap. Cover the trap with a blanket to calm the animal. Then relocate it to a wooded area at least 10 miles away, or contact local wildlife authorities for guidance.
Tips For Successful Trapping
- Use a trap with a solid floor (armadillos dislike wire floors)
- Place boards along the sides of the trap to guide them inside
- Bait the trap with a mix of fruit and insects
- Check local laws before trapping—some states require permits
Method 2: Exclusion With Fencing
Once the armadillo is gone, you must prevent it from coming back. Exclusion is the only long-term solution. Install a barrier around the perimeter of your deck.
Dig a trench 12 to 18 inches deep around the deck. Bury a hardware cloth or galvanized wire mesh (1/4-inch openings) in the trench. Bend the bottom of the mesh outward in an L-shape to stop digging. The mesh should extend at least 6 inches above ground level.
Attach the mesh to the deck supports using staples or screws. Make sure there are no gaps. Armadillos can squeeze through surprisingly small openings.
Materials You Will Need
- Galvanized hardware cloth (1/4-inch mesh)
- Sturdy wire cutters
- Staples or screws
- Shovel for trenching
- Work gloves
Method 3: Habitat Modification
Armadillos come for food. If you remove their food source, they will leave. Treat your lawn for grubs and insects using a grub control product. This reduces the armadillos reason to dig.
Also, remove leaf piles, brush, and wood stacks near the deck. These attract insects and give armadillos cover. Keep your yard clean and well-maintained.
Water your lawn less frequently. Armadillos prefer moist soil because it holds more insects. Drier soil makes digging harder and less rewarding for them.
Method 4: Repellents And Deterrents
Repellents are not as reliable as trapping or exclusion, but they can help in some cases. Use granular repellents containing castor oil or predator urine around the deck perimeter. Reapply after rain.
Motion-activated sprinklers can startle armadillos and discourage them from entering. Bright lights may also help since armadillos are nocturnal and prefer darkness.
Some people use ammonia-soaked rags placed near burrows. The strong smell can drive them away temporarily. However, this is not a permanent solution.
What NOT To Do When Removing Armadillos
There are some common mistakes that can make the problem worse. Avoid these at all costs.
- Do not use poison. It is inhumane and can harm pets or other wildlife.
- Do not try to block the burrow entrance while the armadillo is inside. It will dig a new exit or die trapped.
- Do not use mothballs. They are toxic and illegal for outdoor use.
- Do not attempt to grab or chase the armadillo. They can carry diseases like leprosy, though rare.
Step-By-Step Action Plan
Here is a simple sequence to follow. It combines all the methods above into a clear plan.
- Confirm activity – Look for holes, burrows, and tracks.
- Set a live trap – Place it near the burrow entrance with fresh bait.
- Remove the armadillo – Relocate it legally and safely.
- Install exclusion fencing – Bury hardware cloth around the deck.
- Treat the lawn – Use grub control and reduce watering.
- Maintain the barrier – Check for gaps or damage every few months.
This plan works for most homeowners. If you have a large deck or multiple armadillos, you may need professional help.
When To Call A Professional
If you have tried trapping and exclusion but the armadillos keep coming back, it might be time to call a wildlife removal service. Professionals have experience with stubborn animals and can handle large infestations.
They can also help if you are unsure about local trapping laws. Some states require permits or have specific relocation rules. A pro will handle all that for you.
Costs vary, but a typical removal service runs between $200 and $500, depending on the complexity. It is often worth it for peace of mind.
Preventing Future Armadillo Problems
Once you have solved the current issue, take steps to keep armadillos away for good. Prevention is easier than removal.
- Inspect your deck annually for gaps or damage.
- Keep the area under the deck clean and dry.
- Store firewood and debris away from the house.
- Use gravel or rocks under the deck instead of soil.
- Maintain your lawn with regular grub treatments.
Armadillos are creatures of habit. If they find no food or shelter, they will move on to another yard.
Frequently Asked Questions
Will armadillos eventually leave on their own?
Not usually. Once they find a good food source and shelter, they tend to stay. You need to actively remove them.
Can armadillos damage my deck foundation?
Yes. Their burrowing can undermine support posts and cause settling. This is why prompt removal is important.
What is the best bait for armadillo traps?
Overripe bananas, earthworms, and grubs work well. Some people also use cat food or mealworms.
Are armadillos dangerous to pets?
Armadillos are not aggressive, but they can startle pets. They also carry diseases, so keep dogs and cats away from them.
How deep should I bury the fence to stop armadillos?
At least 12 inches deep, with an outward L-bend of 6 inches. This prevents them from digging under.
