Quick Answer
Armadillo damage in Texas yards appears as dozens of shallow, conical holes (1-3 inches deep, 3-5 inches wide) in a wandering line across the lawn. You may also see uprooted plants and disturbed mulch. The damage is most noticeable in St. Augustine and Bermuda grass lawns where armadillos hunt for grubs at night.
You wake up to find your lawn looks like it was rototilled by a small, armored tank. Dozens of shallow conical holes, each 1-3 inches deep and 3-5 inches wide, scattered across your St. Augustine or Bermuda grass. This is not a vandal. This is a nine-banded armadillo hunting for grubs — and once one finds your yard, it will return nightly until the food source is gone.
Is It Really an Armadillo?
| Animal | Hole Shape | Hole Depth | Damage Pattern |
|---|---|---|---|
| Armadillo | Conical, 3-5 inch diameter | 1-3 inches (shallow) | Dozens of small holes in a wandering line |
| Skunk | Conical, 3-4 inch diameter | 2-4 inches | Fewer holes, more scattered, often near structures |
| Raccoon | Irregular torn patches | Shallow (sod rolled back) | Sod peeled back in sections, not individual holes |
How to Stop Armadillos
- Eliminate the food source. Armadillos dig for grubs and earthworms. Apply beneficial nematodes or milky spore to your lawn to reduce grub populations naturally. Insecticides work faster but harm beneficial insects.
- Install a barrier. A fence buried 12-18 inches deep with an outward-facing L-shaped footer at the base will stop armadillos — they are excellent diggers but poor climbers.
- Motion-activated deterrents. Armadillos have poor eyesight but excellent hearing. Motion-activated sprinklers or ultrasonic deterrents can discourage them — but they may habituate over time.
- Trapping. Live traps baited with overripe fruit or earthworms work, but relocation is regulated by Texas Parks & Wildlife. Check local regulations before trapping.
Lawn Repair
Fill armadillo holes with a 50/50 mix of sand and topsoil. Overseed with your grass type (Bermuda or St. Augustine for most Texas lawns). Water daily for the first week. The lawn will recover fully within 2-3 weeks during growing season.
