Rhipicephalus sanguineus (Brown dog tick)

Rhipicephalus sanguineus or the brown dog tick is extremely rare in Wisconsin.  The tick is usually found in association with domestic dogs, and is able to complete its life cycle indoors in homes or kennels. Recent work has highlighted the involvement of this tick in the transmission of Rocky Mountain spotted fever in American Indian tribes in Arizona, with over 300 cases and 20 fatalities in the period from 2002 to 2011.
