Bronze Birch Borer

Bronze Birch Borers

Bronze Birch Borers are copper or bronze-colored beetles that attack birch trees. These tree pests typically go after birch trees that are already in an unhealthy state. The larva will feed off of the vascular tissue just under the bark. If there is a Bronze Birch Borer infestation it is important to treat early. If gone untreated, your birch will decline and may die within 2 years of the onset of symptoms.
