Japanese Beetle Management in Colorado
Japanese beetles on Echinacea (Coneflower)
Hello Gardening Friend - this site is all about the Japanese beetle in Colorado, specifically the Front Range area. It's organized to assist you with research-based management options, timing and plant lists. There's also a very helpful Q & A document from Colorado State University - Dr. Whitney Cranshaw to answer just about every Japanese beetle question you may have.
The management information, and cultural control practices on this site are recommended by horticulture professionals at Colorado State University and the Colorado Department of Agriculture.
Japanese beetles have been active and destructive in my own garden for several years. I have taken a special interest in this voracious pest and wish to help other home gardeners. My goal is to dispel Japanese beetle myths, missteps and present the research-based management control options. We will get through this together!
I remain in touch with horticulture experts in Colorado who are doing a great service to assist home owners and gardeners by providing Japanese beetle fact sheets, ongoing research and more. These links can be found to the upper right, plus additional information in the drop down menu (More).
With understanding of the Japanese beetle's life cycle and the management options that can be used during the larval and adult stages, we'll continue to enjoy our landscape plants and gardens for many years.
