The longhorned tick (Haemaphysalis longicornis) is an exotic species originally from East Asia that has been identified in several U.S. states, including Arkansas. This tick is known to infest a wide range of hosts, including livestock, pets, wildlife, and humans, and poses a potential threat to animal health and agricultural productivity.
The Arkansas Department of Agriculture works in coordination with federal and academic partners to monitor the presence and spread of the longhorned tick and provide resources for prevention and response.
Why It Matters
The longhorned tick is capable of reproducing rapidly, causing heavy infestations, and carrying disease agents. While these ticks are not currently associated with new risks beyond those from existing species in Arkansas, early detection and prevention remain essential.
For the Public
Longhorned ticks are small and easy to overlook, especially in the nymph stage. Use standard tick prevention measures:
- Avoid tall grass or wooded areas
- Wear repellent and protective clothing
- Perform regular tick checks on yourself and pets
Found a tick? Remove it immediately and submit it for identification through:
- Your local Cooperative Extension office or area health unit (tick kits available)
- The OSU Tick Research Project
For Livestock Owners
Livestock producers should remain alert for signs of tick infestation or unusual herd behavior. Contact the Arkansas Department of Agriculture at (501) 225-1598 if you observe:
- Large numbers of ticks
- Unexplained weakness, weight loss, or reduced production
- Unusual animal deaths
Preventative measures include:
- Maintaining a regular tick control program
- Monitoring animals routinely, especially during warm and humid seasons
- Reducing tick habitat near barns and pastures
