Armadillos are a common sight in many southern and central regions of the United States, and their presence is often first noticed when a homeowner discovers a series of strange, shallow holes scattered across a lawn. These excavations are the work of a natural forager, not a random act of destruction. While the landscape may look unsightly, the activity is a sign of a healthy ecosystem working beneath the soil.
Why Armadillos Dig: The Instinctual Drive
The primary reason armadillos dig holes is rooted in their diet. These animals have poor eyesight but an extraordinary sense of smell, which they use to locate insects, grubs, and larvae buried deep within the earth. When you see small, dime-sized holes peppered across the yard, it is usually the sign of a single animal methodically sweeping its snout across the ground, sniffing out its next meal. This behavior, known as rooting, is essential for their survival and is not an act of spite toward your landscaping.
The Foraging Technique
Armadillos do not usually dig deep pits in search of food. Instead, they use their powerful claws to scratch and loosen the top layer of soil. This technique allows them to quickly expose the insects and worms that thrive in the damp earth. If the holes are numerous and widespread, it indicates a significant population is actively feeding in the area, turning your yard into a hunting ground overnight.
Identifying Armadillo Damage vs. Other Pests
It is important to distinguish armadillo activity from the damage caused by other burrowing animals. Raccoons often roll sod in search of food, leaving distinct patches of torn grass, while skunks create neat, conical holes when rooting for grubs. In contrast, armadillo holes are typically shallow and numerous, resembling a shotgun pattern across the turf. The soil around these holes is usually loosened but not piled into distinct mounds, which helps homeowners correctly identify the culprit.
The Deeper Consequences: Burrows and Risk
While the shallow holes are the most visible issue, armadillos are also prolific diggers of burrows. These larger, tunnel-like structures serve as shelter and nesting sites. A single armadillo can create multiple burrows under structures such as sheds, porches, and decks. These tunnels can extend several feet underground and pose a significant tripping hazard to people walking in the yard. Furthermore, weakened foundations under porches can lead to structural instability over time if left unaddressed.
Managing the Situation Humanely
Because armadillos are protected wildlife in many areas, the most effective approach is to discourage them without causing harm. The most practical method is to remove the food source. Applying insecticides to reduce the population of grubs and larvae in the soil will make your yard less appealing to foraging armadillos. Additionally, ensuring that garbage is secured and yard debris is cleared reduces the presence of insects, thereby making the property less hospitable.
