Emerald Ash Borer Found in Boulder, CO

October 2, 2013Emerald ash borer

This insect has devastated ash trees in many midwestern and eastern states. The Colorado Department of Agriculture has posted information at this location. This pest infests only ash trees. Mountain ash are not ash trees; they belong to a different family of plants and do not develop infestations. Additional information will be posted as it becomes available.

    Has the Ash Borer come to the Denver Metro area? If we have a Mountain Ash tree, do we need to have it treated for the Ash Borer?

      Patty, the Emerald Ash Borer has not been found in the Denver Metro Area. EAB only attacks ash trees in the genus Fraxinus (so mountain ash are not susceptible).
