License required for persons who are hired and compensated to apply pesticides and for not-for-hire applicators who apply restricted use pesticides. Licensed applicators must also hold current pesticide certification in the appropriate certification category. For hire applicators must work for a licensed pesticide application business. Certification is based on the results of a written exam and is required for persons who apply pesticides in a commercial for-hire and commercial not for-hire capacity. Commercial For-Hire Pesticide Applicators: Includes persons who make contractual pesticide applications for which they or their employer receives compensation. Examples are employees of lawn care firms, pest control companies and custom agricultural pesticide applicators. Commercial Not For-Hire Pesticide Applicators: This group includes commercial applicators who make non-agricultural applications to land or buildings they or their employer own or rent and they receive no compensation other than their normal wages. Examples include a power plant employee who uses restricted-use pesticides for weed control on the utility company's property or rights-of-way or, an employee of a food processing plant who uses restricted-use pesticides for pest control only on the plant premises. Commercial Not For-hire pesticide applicators who use restricted-use pesticides must be licensed and certified. Commercial not for-hire applicators who only use non-restricted use pesticides (general use) in the course of their employment are not required by state law to become certified and licensed commercial pesticide applicators.
