In May of 2018, the National Veterinary Services Laboratory in Ames, Iowa confirmed the finding of the Haemaphysalis longicornis tick (otherwise known as the East Asian or Longhorned tick) in Virginia. It was previously unknown in the state, but since then has been detected in 24 counties, mostly in the western part of the state. "The tiny tick can appear on cows, horses and other livestock," said State Veterinarian Dr. Charles Broaddus. "In addition to being a nuisance, they also can be a health risk, especially to newborn or young animals." If you believe you have found the Longhorned tick, notify your local office of the Cooperative Extension Service.
