Emerald Ash Borer (EAB) detected in Broomfield (Aug. 2019), Westminster (Sep. 2019) and Larimer (Oct. 2019)

As a non-native insect, EAB lacks predators to keep it in check. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible). Visit the Colorado Department of Agriculture website for the most up to date information regarding the Emerald Ash Borer in Colorado.
