Armadillos do not typically bite people, but they can. Their mouths are very small with peg-like teeth. The worry about possible armadillo bites stems from the fact that they carry the human form of leprosy. Armadillos can move about quite quickly in what resembles a hopping fashion, but they don't typically chase people nor do they normally bite people. But, armadillos are not one of the most intelligent animals in the world. They do not provide a lot of benefits to the environment but also do not inflict any harm in the wild. The primary nuisance from armadillos is that they enter our yard and garden and dig, seemingly continuously, in search of food. They can quickly tear up your lawn or garden.
