What is the emerald ash borer?
The emerald ash borer is a small insect that bores into the bark of ash trees, eventually killing them. The insect is a small beetle, approximately 1/3 inch in length with a shiny green exterior. It is native to Asia and was first discovered in the United States in 2002 in Michigan. Since then, it has spread throughout the central and eastern US and its presence in Massachusetts was confirmed in 2012.
