Pesticides – Applicator Businesses

The Delaware Department of Agriculture Pesticides section provides the State of Delaware with an exceptional pesticide regulatory program which is educationally based, equitably enforced, and protective of the environment, crops, property, and the health and welfare of all citizens. This is a license issued to all companies that commercially apply pesticides. Anyone buying or using a restricted pesticide must be certified by the Delaware Department of Agriculture. Anyone in the business of applying pesticides, either restricted use or general use, to the land or property of another must be certified and obtain a Pesticide Business License. There are various business license categories: agricultural plant pest control, agricultural animal pest control, fumigation of soil and agricultural products, forest pest control, ornamental and turf pest control, seed treatment, aquatic pest control, right of way pest control, and industrial/institutional/structural/and health-related pest control.
