The emerald ash borer is a metallic green beetle that bores into ash trees feeding on tissues beneath the bark, ultimately killing the tree. It is not native to the United States and was first found in the U.S. near Detroit, Michigan in 2002. In 2013, the emerald ash borer was found in Granville, Person, Vance, and Warren counties in North Carolina. In 2015 it was found in many additional counties, and a statewide EAB quarantine went into effect in North Carolina.
