Longhorned Tick Bulletin

Picture of longhorned tick in 3 growth phases

The Asian longhorned tick, a major pest both physiologically and economically in cattle, is an invasive tick that was recently discovered in the mid-Atlantic. Their populations grow rapidly under warm, humid conditions. This tick was first discovered in Hunterdon County, New Jersey in 2017, although it has likely been present in the United States since 2013. New infestations have recently been discovered in Virginia, West Virginia, and Arkansas.

Below, you will find a bulletin with facts about the longhorned tick which includes what they are, diseases they can spread, how to potentially prevent infestations and what to do if a producer thinks they may have found any on their animals.
