Ticks seem to be a growing problem in the United States and in the Tennessee Kentucky region. There are a number of tick species in the United States but will discuss four species of concern for the region listed above.

Ticks are blood feeding arthropods but are not insects. They have two body regions and they usually have four pairs of legs. Furthermore, the life stages of a tick are the egg, larva, nymph and adult. the larva stage has only three pairs of legs and are often called seed ticks. the tick’s spear like mouth part is barbed that makes it harder to remove the tick while feeding. Ticks can vector diseases that affect humans and animals. Examples are: Rocky Mountain spotted fever, encephalitis, tularemia and Lyme disease.
