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.
As the field season comes to a close, we say good-bye to most of our seasonal staff who have helped to make another successful year of rearing, collecting and shipping insects. Tours of the insectary resume in September through April. Call 970-464-7916, ext. 0 to schedule a tour. Puncturevine weevil collection begins in September.
