Palisade Insectary

Biological control is a method of pest management that uses the natural enemies of weeds or pests. The Palisade Insectary imports, raises, researches, and distributes biological controls for the state of Colorado. Successful biological pest control does three things. It reduces costs and cuts down on the amount of chemicals entering the environment. It also establishes helpful insects for a natural, permanent pest control choice. More than 90 insects and fungi have been studied and released for use since the Insectary was started in 1945.

Our tours are now bi-weekly and are booking fast.  Tours will run through April 2024. Then resume again in September 2024. Call to arrange your tour at 970-464-7916, ext. 0.

 

Did you know that the Palisade Insectary is the premier lab in the U.S. to raise Ceratapion basicorne? These are the weevils that attack the noxious weed yellow star thistle. We are gearing up for a mass rearing with the goal of sending weevils to western states in Spring 2024.
