Distribution: The range of the Gulf Coast is historically described as a region approximately 100-150 miles inland along the Gulf of Mexico and southern Atlantic coast, extending from Texas to South Carolina. Resident populations of Gulf Coast ticks are established in Oklahoma, Kansas, and Arkansas, where their distributions appear to be expanding. Incidental introductions of these ticks beyond endemic regions occurs with increasing frequency; likely due to the feeding of immature ticks on migrating birds, and the transportation of tick infested livestock and wildlife onto new areas.
