Every non-certified applicator who for hire uses or supervises the use of a general use pesticide on land not owned or controlled by the applicator or his or her employer must be licensed. As a minimum requirement for licensing, an applicator must demonstrate a practical knowledge of principles and practices of pest control and safe use of pesticides. This knowledge shall include at least those areas set forth as "general standards" for commercial applicators in 333 CMR 10.04(1).
