Palisade Insectary

Biological control is a sustainable approach to pest management that utilizes the natural enemies of noxious weeds or pests. The Palisade Insectary imports, rears, researches, and distributes biological control agents for the state of Colorado. Successful biological pest control reduces production costs, decreases the amount of chemicals entering the environment, and establishes colonies of beneficial insects offering a natural permanent pest control solution. More than 90 species have been cultured, studied and released for biological control since the Insectary was founded in 1945.
