Vector Information

The blacklegged tick is found in the Northeastern and upper Midwestern states. These ticks can be found during any season as long as temperatures are above freezing. They are able to transmit several diseases to humans but are easily identifiable. The most common forms to bite humans are nymphs and adult females. Adult males do not feed on blood but will attach. These ticks are able to transmit Lyme disease, anaplasmosis, babesiosis, and Powassan disease. These ticks are identifiable from their black legs and adult females are easily distinguishable with their red-orange body and black scutum. These ticks are found in deciduous forests.

*Disease transmission varies locally. This map depicts where vectors can be found geographically and provides information about diseases these vectors might carry. Vectors might be present in a state or locality, however, and not be carriers of any particular disease. In addition, identified vectors may have a presence in a state, but may not be found throughout that state.
