Emerald Ash Borer (EAB)                                               

The Emerald Ash Borer (Agrilus planipennis or EAB) is responsible for the destruction of tens of millions of ash trees in 25 states in the Midwest and Northeast. Damage occurs in infested trees due to larval feeding. The serpentine feeding galleries of the larvae disrupt the flow of nutrients and water effectively girdling the tree.

Native to Asia, it likely arrived in the United States hidden in wood packing materials. The first U.S. identification of Emerald Ash Borer was in southeastern Michigan in 2002. Most trees die within 2 to 4 years of becoming infested. The emerald ash borer is responsible for the destruction of over 50 million ash trees in the U.S. since its discovery in Michigan. It is especially dangerous because there is no known treatment for EAB infestations - trees must be felled and the wood disposed of by a licensed arborist/tree service. It is advised  not to remove it from the area, to avoid spreading the EAB to other areas. If you are in an affected area, there may already be quarantine restrictions in place. The wood can be utilized locally; it can be made into outdoor furniture by the home owner or used as firewood. If the tree is in a wooded area, it can be left standing because dead trees contribute to the ecosystem as habitats for many animals. Always speak to your local municipality or state office if you have any questions or for information on the regulations in your area.

  

The beetle is currently found in Arkansas, Colorado, Connecticut, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and Wisconsin. If you see an infestation in your area, it would be wise to contact your local county extension office.
