Asian Longhorned Tick
The Asian Longhorned tick is an invasive species now found in 12 states.
Who's at Risk?
While no human illnesses have been reported in the US, in Asia it is a vector for Japanese encephalitis.
This tick has been found in sunny areas with short grass—an environment that other ticks avoid. It attacks cattle and other animals. It is not uncommon to find thousands of ticks on a single victim. Experts are watching this tick closely to make sure it's not spreading tick-borne diseases commonly found in the US.
