What is a key characteristic of the blacklegged tick?

A key characteristic of the blacklegged tick is its role in the transmission of Lyme disease. These ticks are the primary vectors for this illness, which they spread when they attach to a host and feed on their blood. Lyme disease can have serious health implications if not detected and treated early, making the blacklegged tick particularly important in discussions about public health and pest management.

Blacklegged ticks do not exclusively inhabit urban areas, nor are they primarily found in water. Instead, they thrive in wooded, brushy, or grassy environments, which are often near natural areas rather than heavily urbanized regions. Additionally, these ticks are known for their ability to attach firmly to human hosts during their feeding process, contrary to the assertion in the option stating they do not attach to humans. Hence, understanding the blacklegged tick's role as a vector for Lyme disease is critical for effective pest management and public health strategies.
