*It is important to note that the pathogen that causes Lyme disease is maintained by wild rodent and other small mammal reservoirs, and is not transmitted everywhere that the blacklegged tick lives. In Arkansas, the tick has feeding habits that make it an unlikely vector in the spread of human disease.
**Both nymphal and adult lone star ticks may be associated with the transmission of pathogens to humans.
