Western Blacklegged Tick Surveillance

At a glance

The western blacklegged tick (Ixodes scapularis) is found along the Pacific coast of the United States, particularly northern California. Larvae and nymphs often feed on lizards, birds, and rodents, and adults more commonly feed on deer. Although all life stages bite humans, nymphs and adult females are more often reported on humans.
