Are you certified? How? What is required by your state to become certified for pesticide application? Maryland says: "In order to become certified as a pest control applicator, an individual must have at least one year of practical pesticide application experience as a registered employee in the category, or categories, in which he/she wants to become certified. A degree in a biological field such as biology, botany, horticulture, entomology, agronomy, etc. may qualify in lieu of experience. The individual must pass examinations administered by MDA." Is it different from state to state?
