Black-legged ticks, also known as deer ticks, are notorious arachnids that are distinguishable by their small size and dark legs. Although its size is much smaller than that of a dog tick, it is responsible for spreading many bacterial diseases through its bites like Lyme disease, Powassan encephalitis, anaplasmosis, and babesiosis. Of all these black-legged tick diseases, Lyme disease is the most common in humans. It is of extreme medical relevance in the northeast United States because it affects the health of both humans and animals. The origin of these ticks is unknown but over the past century, they have rapidly expanded in the east of the United States, especially the northern part. Earlier, they were recorded along the northern Atlantic Coast, the Gulf Coast, and the Southeast. In the '20s, small populations were also recorded in New England, Rhode Island, Long Island, New York, and Wisconsin.
