Armadillos: Understanding and Managing These Unique Backyard Visitors

Identification and Biology of Armadillos

Armadillos are small to medium-sized mammals belonging to the family Dasypodidae. The most common species in the United States is the nine-banded armadillo (Dasypus novemcinctus), which has been steadily expanding its range northward from its native habitats in Central and South America.

Physical Characteristics

Armadillos are easily recognizable due to their unique physical features:

  • Shell: The most distinctive feature of armadillos is their bony, armor-like shell. This shell is composed of overlapping scales called scutes, which provide protection from predators.
  • Size: Nine-banded armadillos typically measure 24-32 inches in length, including their long, scaly tails.
  • Weight: Adults usually weigh between 8-17 pounds.
  • Color: Their shells are generally grayish-brown, while the skin on their undersides is softer and lighter in color.
  • Legs: Armadillos have short, sturdy legs with sharp claws, perfect for digging.
  • Head: They have a long, pointed snout and small, beady eyes.

Life Cycle

Understanding the life cycle of armadillos can help in managing their presence:

  • Breeding: Armadillos typically mate in late summer or early fall.
  • Gestation: The gestation period lasts about four months, but implantation is delayed for several months.
  • Birth: Females give birth to four identical quadruplets in the spring.
  • Development: Young armadillos are born with soft shells that harden as they mature.
  • Maturity: Armadillos reach sexual maturity at about one year of age.
  • Lifespan: In the wild, armadillos typically live 7-20 years.

Habitat and Distribution

Armadillos prefer warm, moist climates and are found in a variety of habitats:

  • Forests
  • Grasslands
  • Scrublands
  • Suburban areas with sufficient cover and food sources

Originally native to South and Central America, armadillos have expanded their range into the southeastern United States. They're now commonly found in states like Texas, Oklahoma, Louisiana, Arkansas, and Florida, and have been observed as far north as Nebraska and Illinois.

Armadillo Behavior and Habits

To effectively manage armadillos, it's crucial to understand their behavior and habits:

Digging Behavior

Armadillos are prolific diggers, using their strong claws to excavate burrows and search for food. This behavior can lead to several issues for property owners:

  • Creation of burrows up to 15 feet long and 5 feet deep
  • Damage to lawns and gardens while searching for insects and grubs
  • Potential undermining of structures like patios, sidewalks, and foundations

Feeding Habits

Armadillos are primarily insectivores, with a diet consisting of:

  • Insects (beetles, ants, termites)
  • Grubs and worms
  • Spiders
  • Small reptiles and amphibians
  • Occasional fruits and berries

Their foraging behavior often results in shallow holes and upturned soil in lawns and gardens.

Activity Patterns

Armadillos are primarily nocturnal, being most active during the night and early morning hours. However, they may be seen during daylight hours in cooler weather. They're generally solitary animals, coming together only for mating.

Potential Risks and Concerns

While armadillos are not typically aggressive towards humans, their presence can lead to several concerns:

Property Damage

The most common complaint associated with armadillos is property damage, including:

  • Lawn and garden destruction from digging
  • Damage to ornamental plants and vegetables
  • Burrowing near or under structures, potentially compromising their stability
Health Risks

While rare, armadillos can pose some health risks:

  • Leprosy: Armadillos are one of the only known animals besides humans that can carry Mycobacterium leprae, the bacterium that causes leprosy. However, transmission to humans is extremely rare and typically requires prolonged, direct contact with an infected animal.
  • Other diseases: Like many wild animals, armadillos can potentially carry parasites or other pathogens.
Ecological Impact

As an introduced species in many areas, armadillos can have both positive and negative ecological impacts:

  • Positive: They can help control insect populations and aerate soil through their digging.
  • Negative: They may compete with native species for resources or prey on ground-nesting birds' eggs.

Prevention and Management Strategies

Preventing and managing armadillo activity on your property involves a combination of habitat modification, exclusion techniques, and professional assistance when necessary.

Habitat Modification

Making your property less attractive to armadillos can help deter them:

  • Remove food sources: Treat your lawn for grubs and insects, which are primary food sources for armadillos.
  • Reduce moisture: Fix leaky faucets and improve drainage in your yard, as armadillos prefer moist soil for digging.
  • Clear brush and debris: Remove piles of brush, rocks, or lumber that might provide shelter for armadillos.
  • Trim vegetation: Keep shrubs and bushes trimmed to reduce cover and make your yard less appealing.

Exclusion Techniques

Physical barriers can be effective in keeping armadillos out of specific areas:

  • Fencing: Install sturdy fencing that extends at least 12 inches into the ground to prevent burrowing. The fence should be at least 24 inches high, as armadillos can climb.
  • Barriers around structures: Use heavy mesh or chicken wire to create underground barriers around decks, sheds, or other structures.
  • Garden protection: Use raised beds or install wire mesh at the base of your garden to prevent armadillos from accessing plants.

Repellents and Deterrents

While not always foolproof, some repellents and deterrents may help discourage armadillos:

  • Scent deterrents: Strong smells like ammonia or vinegar may deter armadillos. Place soaked rags near burrows or entry points.
  • Motion-activated sprinklers: These can startle armadillos and make your yard less inviting.
  • Lights: Since armadillos are nocturnal, bright lights or motion-activated lighting may discourage nighttime activity.

  • Check with your local wildlife agency or a pest control professional to understand the legal methods for managing armadillos in your area.
  • Some methods of control, such as trapping or relocation, may require permits or need to be carried out by licensed professionals.
