Overview

American dog ticks are found over most of North America, predominantly along forest edges and in areas with little or no tree cover, such as grassy fields and scrubland, as well as along walkways, sidewalks, and trails. American dog ticks are 3-host ticks (use 3 different hosts in their lifecycle) feeding on people and a variety of animals ranging in size from rodents to livestock. Adult stages prefer medium-sized hosts, including racoons, skunks, cats, dogs and other canids. Larvae and nymphs mainly infest small mammals including mice, voles, rats, and chipmunks. Nymphs and adults can transmit Rocky Mountain Spotted Fever and lesser pathogenic spotted fever group germs as well. They also transmit the germ causing Tularemia. American dog ticks can survive for up to 2 years at any given life stage if no host is found.
