Which type of pesticide can only be purchased and used by certified applicators?

The category of pesticide that can only be purchased and used by certified applicators is classified as a Restricted-Use Pesticide. These pesticides have a higher potential for causing harm to humans, wildlife, or the environment due to their toxicity or specific application requirements. As a result, regulatory agencies implement strict guidelines that prohibit their use by untrained individuals. This ensures that only those who have received the necessary training and certification can handle these products, thereby minimizing risks associated with improper application.

In contrast, General-Use Pesticides are designed for public use and can be safely handled by non-certified individuals. Specialty Pesticides may refer to products aimed at specific pests or situations but do not inherently require certification for use. Household Pesticides are typically lower-risk products formulated for domestic use and are available without the need for special certification. Understanding these distinctions is crucial for ensuring safety and compliance in pest management practices.
