North Carolina is now under attack by a small green beetle that bores into ash trees otherwise known as the emerald ash borer (EAB). The emerald ash borer causes damage while gathering nourishment from the tissue underneath the bark, while simultaneously killing the tree. EAB has now been found in many Midwestern and eastern states at the expense of tens of millions ash trees.
The emerald ash borer attacks all species of ash native to the United States including, white ash, green ash, Carolina ash, and pumpkin ash and spreads in a variety of ways. EAB can spread naturally by a beetle flying to a new host tree; however, this circulation is limited to a few miles. The more serious spreading threat is the transportation of an ash product from an infested area to an uninfected area.
As transportation of ash products continues to pose a huge threat, the state of North Carolina is now considered quarantined. This means, no part of an ash tree, the insect itself, or all hardwood firewood can be moved from a quarantined area into an area outside the quarantine. At this time, these materials can still be moved freely within the state of North Carolina.
In North Carolina, the adult emerald ash borer is expected to be most active in late spring. Yet, emerald ash borer larvae may be found under the bark throughout the year. The best option to combat against a known EAB infestation is to cut down the dead and dying ash trees and chip, burn, or bury the wood on the site. Insecticides are the best option when wishing to protect or to help the trees recover. It is best to consult with a certified arborist to decide the best course of action when combating against emerald ash borer.
