Emerald Ash Borer (Agrilus planipennis) is an exotic beetle that has killed millions of ash trees and the number continues to increase. There has been an extensive ongoing effort by the scientific community to better understand the problem, and to develop effective control tactics to combat the spread of this destructive pest.
Application is most appropriate after EAB infestation has been detected within 15 miles, and most effective when applied before trees are infested or with a low level of infestation. All ash trees can be adequately protected with an annual soil application. Property owners should work with a certified arborist to determine the best course of action on a tree-by-tree and property-by-property basis.
