Pesticide applicator license requirements in Ohio

Commercial applicator

Ohio licenses commercial pesticide applicators through the Ohio Department of Agriculture (ODA). The application fee is $35, paid annually, and the applicator must pass the Core exam plus an exam for each category of pesticide work they perform. A separate $35 pesticide business license, with proof of liability insurance, is required to operate commercially; ODA lists four business-license types (standard business, solicitation-only, registered location, and pesticide dealer).

Wood-Destroying Insect Inspector

Ohio treats wood-destroying insect inspection (termite and similar inspections, Category 12) as its own category with mandatory initial training and a distinct recertification requirement: 5 credit hours every 3 years, split 1 core hour and 4 category hours.

Trained serviceperson

Ohio also allows a “trained serviceperson” to apply pesticides without a formal license, provided they complete training before their first pesticide exposure and work under the direct supervision of a licensed applicator within 25 miles or 2 hours of availability.

Renewal and continuing education

Commercial applicator recertification runs on a 3-year cycle in Ohio. Ohio State University Extension’s Pesticide Safety Education Program administers most of the required training and study materials on the department’s behalf.

Reciprocity

ODA does not publish a standing reciprocity table for incoming commercial applicators online; an applicator relocating to Ohio should contact ODA directly to confirm whether an out-of-state credential is recognized.
