fly swatterPest Identification

Identifying a pest is the first step to preventing and controlling it. Once you’ve identified your pest you can learn about it so you can develop a control plan.

Look It Up

Identify the pest online using an illustrated pest identification guide, which can be found on cooperative extension service, university and government websites. You can also find printed guides from your library or cooperative extension office.

Ask an Expert

Consult a pest expert through a cooperative extension office, such as the OSU Insect ID Clinic. A pest professional, farm advisor, agricultural commissioner, or USDA biologist can also help.
