Online Tick Course Now Available through OSU Extension

Lyme disease is transmitted by the blacklegged deer tick, which is much smaller than the common American dog tick.

COLUMBUS, Ohio – Tick populations are on the rise in Ohio and with them comes the risk of contracting illnesses such as Lyme disease.

To help Ohioans learn more about ticks and how to keep people and pets safe, Ohio State University Extension has developed an online course that teaches about tick biology, tick identification and tick-borne diseases.

"With the warmer weather, ticks will be active and looking to feed," said Glen Needham, an entomologist and tick expert with OSU Extension, the outreach arm of the university's College of Food, Agricultural, and Environmental Sciences.

Developed by Needham and Denise Ellsworth, director of the Department of Entomology's Honey Bee and Native Pollinator Program, the course is geared toward hunters, gardeners, veterinary professionals, Extension professionals and others engaged in outdoor activities or educating the public.

The not-for-credit Tick Course consists of videos, self-paced lessons, quizzes and Internet resources and takes approximately three hours to complete, Ellsworth said. The cost is $10.

The course is available through eXtension, the national Extension system's website, at To get started, you will need to create an account at eXtension. The course can be found in the "Yard and Garden" category.
