Centers for Disease Control and Prevention - Brown Dog Tick

This map is not meant to represent risks for a specific tick-borne disease, because disease transmission is influenced by multiple factors beyond mere tick presence. This map has been designed to answer the question “What ticks should I be concerned about at a regional scale?” Please consult a local public health authority or USDA Agricultural Extension Office to determine more specific information at the state, county, or municipal level. Background data for this map is from the US National Atlas.

Sighting and Biting notes:

  • Dogs are the primary host for the brown dog tick during its life stages.
  • The Brown Dog tick may also bite humans or other mammals.

Potential to Carry: 

  • Rocky Mountain spotted fever (in the southwestern U.S. and along the U.S./Mexico border).
