A National Veterinary Services Laboratory test has confirmed the Haemaphysalis longicornis tick in Maryland. It is commonly known as the longhorned tick or the bush tick.

The tick was found on a white-tailed deer in Washington County on Friday, July 27. 

"In order to keep livestock and pets safe, we encourage owners to check their animals for a high concentration of tick bites or abnormal ticks," Maryland Department of Agriculture's State Veterinarian Dr. Michael Radebaugh said. "These species of ticks are known to cling to hosts in high numbers. If too many of these ticks attach themselves to an animal, it could cause stunted growth, decreased production, major blood loss, and has the potential to spread diseases. 

The tick is not native to Maryland and have previously carried infectious pathogens. 

Ticks can be found in tall grasses, meadows, pastures and wooded areas.
