DistributionRead full entry
Cayenne ticks, Amblyomma cajennense, are distributed over a large portion of the Americas, from the United States to Argentina. They are found throughout much of Central America and the Caribbean Islands. In South America, they are prevalent from the Pacific coast to the Atlantic coasts, extending into southern Chile. Within the United States, cayenne ticks occur in southern and western states, most notably those in the Rocky Mountains. In this region, some ticks of the Family Ixodidae, including cayenne ticks, carry Rocky Mountain spotted fever, a tick-borne disease caused by the bacterium Rickettsia rickettsii.
