Armadillos, particularly the nine-banded armadillo (Dasypus novemcinctus), have gained notoriety as destructive pests due to their burrowing behavior and potential for disease transmission. However, recent research suggests that these armored mammals may play a crucial role in supporting biodiversity and ecosystem health.
Key Facts
- Property damage: Armadillos are known for their burrowing behavior, which can cause damage to lawns, gardens, golf courses, and even foundations of buildings. Their digging can uproot plants, damage pavement, and disrupt agricultural fields.
- Disease transmission: While rare, armadillos can carry diseases that can be transmitted to humans. The most well-known disease associated with armadillos is leprosy, although the risk of transmission is low. Additionally, armadillos can host parasitic worms and, in rare cases, carry rabies.
- Negative impact on ecosystems: Armadillos are not native to all areas where they are found, and their presence can disrupt local ecosystems. They can compete with native species for resources and alter habitats through their burrowing activities.
Property Damage: A Cause for Concern
Armadillos are known for their extensive burrowing, which can cause significant property damage. Their digging can uproot plants, damage pavement, and disrupt agricultural fields (Critter Team, 2021). Golf courses and lawns are also vulnerable to their burrowing activities, leading to unsightly mounds of dirt and potential hazards for golfers and homeowners alike (Critter Control, 2023).
Disease Transmission: A Public Health Risk
While the risk is low, armadillos can carry diseases that can be transmitted to humans (Critter Control, 2023). The most well-known disease associated with armadillos is leprosy, caused by the bacterium Mycobacterium leprae. Although rare, cases of leprosy linked to armadillos have been reported in the United States and other countries (Critter Control, 2023). Additionally, armadillos can host parasitic worms and, in rare cases, carry rabies (Critter Control, 2023).
Negative Impact on Ecosystems: A Threat to Biodiversity
Armadillos are not native to all areas where they are found, and their presence can disrupt local ecosystems (The Revelator, 2022). They can compete with native species for resources such as food and shelter, potentially leading to population declines (The Revelator, 2022). Furthermore, their burrowing activities can alter habitats, affecting soil structure and vegetation composition (The Revelator, 2022).
Conclusion: Weighing the Pros and Cons
Armadillos can be a nuisance due to their property damage and potential for disease transmission. However, they also play a role in supporting biodiversity and ecosystem health by providing shelter and food for various species. As we continue to learn more about the complex interactions within ecosystems, it is important to consider the potential benefits of armadillos before resorting to eradication efforts.

FAQs
What kind of damage can armadillos cause?
Armadillos can cause damage to property through their extensive burrowing, which can uproot plants, damage pavement, and disrupt agricultural fields. They can also damage lawns and golf courses by creating unsightly mounds of dirt.
Can armadillos transmit diseases to humans?
Yes, armadillos can carry diseases that can be transmitted to humans, although the risk is low. The most well-known disease associated with armadillos is leprosy, caused by the bacterium Mycobacterium leprae. Additionally, armadillos can host parasitic worms and, in rare cases, carry rabies.
How do armadillos impact ecosystems?
Armadillos can have a negative impact on ecosystems, particularly in areas where they are not native. They can compete with native species for resources such as food and shelter, potentially leading to population declines. Their burrowing activities can also alter habitats, affecting soil structure and vegetation composition.
Are armadillos considered pests?
Armadillos are often considered pests due to the damage they can cause to property and crops, as well as their potential for disease transmission. However, it is important to note that armadillos also play a role in supporting biodiversity and ecosystem health by providing shelter and food for various species.
What can be done to manage armadillo populations?
There are several methods that can be used to manage armadillo populations, including exclusion techniques, trapping and removal, and habitat modification. Exclusion techniques involve sealing off areas where armadillos can burrow or enter buildings. Trapping and removal should be conducted by trained professionals to ensure the safety of both humans and armadillos. Habitat modification involves altering the environment to make it less suitable for armadillos, such as removing sources of food and shelter.
Are there any benefits to having armadillos around?
Armadillos can provide some benefits to the environment. They help to control populations of insects and other invertebrates, and their burrowing activities can help to aerate the soil. Additionally, armadillos are a food source for some predators, such as coyotes and owls.
What should I do if I encounter an armadillo?
If you encounter an armadillo, it is best to leave it alone. Armadillos are generally shy and will avoid contact with humans. If an armadillo is causing damage to your property, you should contact a professional pest control company for assistance.
Are there any natural predators of armadillos?
Armadillos have several natural predators, including coyotes, wolves, mountain lions, and large birds of prey such as eagles and hawks.
