Free Insects: The Request-a-Bug Program

Weeds and unwanted pests present a challenge to gardeners. The Colorado Department of Agriculture’s “Request-a-Bug” program offers an alternative to pesticides. Colorado residents can obtain free biological pest control agents (insects) by going to the Biological Pest Control Request-a Bug Program website. Fill out a form on this site to have the bugs sent to your home.

Because the biocontrol agents are usually host specific, you must accurately identify the species you are trying to control. The site includes a link to the Colorado Weed Management Association Noxious Weeds site to help with identification. Additional information can be found in the CSU Cooperative Extension’s Gardening Online Fact Sheets and Insects Online Fact Sheets. In addition, a search in our online catalog turns up many publications on weeds, insects, and organic gardening which can be borrowed from our library. One helpful title is Weeds of Colorado: A Comprehensive Guide to Identification, 1998, by Robert Zimdahl, published by Cooperative Extension.
