Ohio Tracks Tick Threats with New Testing Support for Farmers

By Andi Anderson

Ohio continues to see year-round tick activity, with increasing concern over the invasive Longhorned tick, especially for cattle producers.

Once first discovered in 2020, this tick species has now been confirmed in 19 Ohio counties, including Gallia, Franklin, Ross, Athens, and more. Experts expect this list to grow in 2025.

The Longhorned tick poses serious risks to cattle. It can lead to blood loss and transmits the disease Theileria orientalis, a protozoal parasite. Theileria can cause high heart and breathing rates, anemia, jaundice, and even death in cattle.

There is no approved treatment for this disease in the U.S., and affected animals may become long-term carriers. If symptoms appear, a veterinarian can test blood samples to confirm the infection.

Farmers are advised to begin scouting for ticks early. Although tick outbreaks peak in July, ticks can emerge as early as March, as seen in 2025. Many fly control products are also effective against ticks, but not all of them are effective.

It's important to follow product labels closely to ensure proper usage against both pests. Choosing the right product and knowing when to apply it depends on individual farm needs and pest activity.

A helpful new resource for Ohio farmers is the Buckeye Tick Test Laboratory from Ohio State University. The lab offers tick-borne pathogen testing for $49.99 per tick, with results available within 72 hours. This fast, cost-effective service is designed to help protect both animals and people from growing tick-borne threats.
