Lone Star Tick

A thirst for blood that’s as big as Texas

While it is found in Texas as well as other places, the lone star tick (Amblyomma americanum) gets its name from the small white “star” that is visible on the backs of females. It also has a reputation for being one of the more voracious and aggressive feeders.


The lone star tick can transmit ehrlichiosis, Rocky Mountain spotted fever and southern tick-associated rash illness (STARI). These are also zoonotic diseases, which means they can infect people as well as pets. The lone star tick is commonly found in the middle-southern, central and southeastern regions of the United States, as well as along the East Coast and in Canada.
