The emerald ash borer, Agrilus planipennis, (EAB) is an invasive pest that threatens our ash tree population. The emerald ash borer is now one of the most destructive non-native insects in the United States.

The “Green Menace” was positively identified in Bucks county, PA on March 15, 2012. It is recommended that Ash trees be treated preventatively (View our post “Treating for the Emerald Ash Borer” see how that is done.).


  • They only attack ash trees (Fraxinus spp.)
  • Adult Beetles are metallic green and about 1/2-inch long.
  • Adults leave a D-shaped exit hole in the bark when they emerge in spring.
  • Woodpeckers like EAB larvae. Heavy woodpecker damage on ash trees may be a sign of infestation.
  • Firewood cannot be moved in many areas of Michigan, Illinois, Indiana, Maryland, Minnesota, Missouri, New York, Ohio, Ontario, Pennsylvania, Tennessee, Virginia, West Virginia, and Wisconsin because of the EAB quarantine.
  • The emerald ash borer probably came in from Asia in wood packing material.

Research trials have shown systemic treatments are highly effective. This treatment will provide year long benefits and also help against other insects such as Aphids, Leaf Hopper, and more. Contact your representative for more information about Tamke’s pest control services.
