Armadillos are fascinating creatures, but their presence in residential areas often leads to significant concerns about property damage. The primary indicator of their activity is the presence of distinct armadillos holes, which can disrupt carefully maintained lawns and gardens. Understanding the characteristics of these excavations is the first step in identifying an infestation and implementing effective control strategies.
Identifying Armadillo Holes
Unlike the neat mounds of gophers or the crescent-shaped piles of voles, armadillo holes have a specific appearance that sets them apart. These excavations are typically shallow, measuring between one and three inches deep, although they can occasionally reach greater depths in search of grubs. The entrance is usually a circular opening approximately two to three inches wide, resembling a small crater with loose, scattered soil around the rim.
The Foraging Behavior Behind the Damage
The reason armadillos dig is rooted in their diet. These nocturnal animals are prolific foragers, using their keen sense of smell to locate insects, grubs, and larvae just beneath the surface of the soil. When an armadillo detects prey, it uses its strong front claws to rip through the turf in search of a meal. Consequently, the presence of numerous small holes is often a sign that the creature is actively feeding on pests within the lawn.
Distinguishing from Other Pests
Homeowners often confuse armadillo activity with that of other burrowing animals. Moles create raised tunnels and volcano-shaped mounds, while groundhog holes are large and feature a distinct pile of dirt at the entrance. In contrast, armadillos are less systematic; their holes are random and numerous, lacking the organized tunnel systems of moles. This scattered pattern results in a yard that looks as if it has been disturbed by a series of small, shallow explosions.
Potential Risks and Hazards
While the holes themselves are an eyesore, the dangers they pose extend beyond aesthetics. The irregular terrain created by frequent digging can become a tripping hazard for people walking across the yard. Furthermore, if an armadillo feels threatened, it may attempt to burrow underneath structures such as sheds or porches, potentially compromising the foundation. There is also the risk of the animal contracting and transmitting diseases such as leprosy, making professional handling essential.
Prevention and Exclusion Tactics
Preventing armadillos requires making the environment less appealing. Since they are attracted to grubs, treating the lawn for insect pests can reduce the food source that draws them in. Installing a sturdy fence that extends underground can be effective; the barrier should descend at least 18 inches to prevent the animal from slipping underneath. Keeping grass trimmed short removes the cover they prefer, making them less likely to take up residence.
Professional Removal Considerations
Once armadillos have established a presence, removal can be challenging. Trapping is often the most effective method, but it requires strategic placement near active holes. Because these animals can carry diseases, it is generally recommended to contact wildlife control professionals. Experts can humanely relocate the animal and provide advice on repairing the damage and securing the property against future visits.
