They are arachnids, not insects. There are hundreds of different kinds of ticks in the world. Many of them carry bacteria, viruses or other pathogens that cause disease in humans and/or animals. In the midwestern and eastern United States, Ixodes scapularis or deer tick is the primary vector of Lyme disease. On the West Coast, the spirochete is carried by Ixodes pacificus or western black-legged tick.
Ticks are vectors of Lyme disease.. Black-legged ticks (Ixodes scapularis) are responsible for transmitting Lyme disease bacteria to humans in the northeastern and north-central United States. On the Pacific Coast, the bacteria are transmitted to humans by the western black-legged tick (Ixodes pacificus). Ticks are related to spiders and mites in the Arachnid Class. The black-legged tick falls within the family Ixodidae, or hard ticks.
