Pesticide Product Registration Requirements

All pesticides that are sold or used in Connecticut must be registered with the Department of Energy and Environmental Protection (DEEP) Pesticide Program.  Pesticides are broadly defined and include insecticides, herbicides, antimicrobials, fungicides and most other products that are designed or marketed to control or repel a pest.  The manufacturer or distributor is responsible for registering the product.  In most cases, federal EPA registration must be obtained before the state registration process can begin. Note:
