Watch for the Longhorned Tick

The longhorned tick (Haemaphysalis longicornis), an exotic tick from east Asia, was detected recently in Benton County, Arkansas. It was initially found in New Jersey in 2017, and has also been collected in West Virginia and Virginia. There are no known links between the cases. To date, this tick has not been found in Kentucky.

The longhorned tick has a wide host range that includes wildlife species, humans, dog, cats, and livestock. Heavy infestations can stunt growth, decrease production, and cause animal death. In addition, it is associated with tick-borne bacterial and viral diseases of animals.

Take suspected samples of this tick to your local Cooperative Extension Service office for identification.  For more information see this article by the New Jersey Department of Agriculture
