How a small Colorado town fought the Japanese beetle and won

Eradicating invasive species requires enrolling a community effort. Although quarantines and chemical treatments have not proven effective in preventing the spread of Popilia japonica, or the Japanese beetle, to farms on the US’s Front Range, the Colorado community of Palisade succeeded in eradicating the species through collective action. By combining pest control methods with a community program of reducing water use, Palisade farmers were able to push the beetles out of their farmland over the course of several years in the early 2000s.
