Quick Answer
Armadillos in Texas cause distinctive yard damage: cone-shaped holes (1-3 inches deep, 2-4 inches wide) scattered across lawns, flower beds, and gardens. They dig for grubs, worms, and insects. Armadillos are about the size of a house cat, with a leathery shell, long pointed snout, and strong claws. They are nocturnal and solitary. Signs include shallow rooting, overturned flower pots, and disturbed mulch. Armadillos are not aggressive but can carry leprosy (Mycobacterium leprae).
Texas Armadillo Yard Damage: Identification & Prevention
The nine-banded armadillo (Dasypus novemcinctus) is common throughout Texas. While they are fascinating creatures, their foraging behavior can devastate a well-maintained lawn and garden. They dig characteristic cone-shaped holes as they search for grubs, earthworms, and insects.

Armadillo Damage Identification
| Damage Type | Description | Animal |
|---|---|---|
| Cone-shaped holes | 1-3 inches deep, 2-4 inches wide, scattered | Armadillo |
| Large irregular diggings | 6-12 inches deep, in garden beds | Armadillo (for grubs) |
| Rooted-up sod | Sections of lawn turned over | Armadillo |
| Disturbed mulch | Mulch scattered in flower beds | Armadillo |
| Overturned pots | Small pots knocked over | Armadillo |
| Burrows | 8-10 inch diameter, under structures | Armadillo (den) |
| Tracks | Four toes on front, five on hind, claw marks | Armadillo |
Armadillo Behavior
Armadillos are solitary, nocturnal insectivores. They spend their nights foraging for food, using their strong sense of smell to locate grubs, worms, and insects 2-6 inches below the soil surface. They dig with their powerful front claws, creating the characteristic cone-shaped holes. They are not territorial and will move through an area for 1-3 nights before moving on.
Prevention Methods
Exclusion (Most Effective)
The most effective long-term solution is exclusion. Install a fence that extends 12-18 inches below ground (armadillos dig) and 12-18 inches above ground. Use heavy-gauge wire mesh or hardware cloth. Seal access under decks, porches, and sheds with the same materials.
Grub Control
Armadillos dig for grubs. Reducing the grub population in your lawn makes it less attractive to armadillos. Apply beneficial nematodes or milky spore to control grubs naturally. Chemical grub control is also effective but may affect beneficial insects.
Repellents
Armadillo repellents have mixed effectiveness. Some people report success with castor oil-based repellents, predator urine, or motion-activated sprinklers. However, repellents are generally less effective than exclusion.
Health Concerns
Armadillos are known carriers of Mycobacterium leprae, the bacteria that causes leprosy (Hansen's disease). However, transmission to humans is very rare and requires direct, prolonged contact with the animal. The risk to homeowners is minimal. Normal precautions apply: do not handle armadillos, wear gloves if you must touch one, and wash hands thoroughly.
FAQ: Texas Armadillo Damage
How long do armadillos stay in one yard?
Armadillos typically move through an area for 1-3 nights before moving on to find new food sources. If your yard has a high grub population, they may stay longer.
Can armadillos damage my foundation?
Yes, armadillos can dig burrows under foundations, patios, and sheds. Their burrows can undermine structural integrity. If you find a burrow under a structure, it should be filled and the area sealed.
