Deer Tick

(Ixodes scapularis)

Ixodes scapularis, commonly known as the blacklegged tick or deer tick, is an ectoparasite (external parasite) that gets its nutrients from animal blood. This tick may carry tick-borne diseases such as Anaplasmosis, Babesiosis, Bartonellosis, Borrelia miyamotoi, and Lyme disease.

To identify a female deer tick, look for a reddish-brown body and a black shield on its back. Its mouth parts are long and thin, and there are no festoons present along the abdomen.

The Tick Research Lab of Pennsylvania is able to detect the most common tick-borne diseases in any of these species. Our tick DNA tests are over 99.9% accurate.
