What Is Emerald Ash Borer?
The Emerald Ash Borer is an exotic metallic green beetle that attacks ash trees. It has already killed over 40 million ash trees since it was first discovered in Southeastern Michigan in the summer of 2002. Native to Asia, Emerald Ash Borer came to the United States on solid wood packing materials, and has now spread to 26 states, including Pennsylvania. It was discovered in Pennsylvania in June 2007. While the adult Emerald Ash Borer nibbles on ash foliage and causes little damage to ash trees, the larvae feed on the inner bark of the tree, disturbing the tree’s ability to transport water and nutrients, and ultimately killing the tree.
