Overview

Missouri regulates pest control through the Missouri Department of Agriculture (MDA), Bureau of Pesticide Control. The state requires all commercial pesticide applicators to be certified and pest control businesses to be licensed. Missouri's central location and varied climate create diverse pest management needs.

The MDA ensures that pest control professionals meet competency standards through examination and continuing education. The state offers multiple certification categories for different pest control specialties.
