Emerald Ash Borer was first discovered in 2002 in southeast Michigan, and is responsible for the death or damage of approximately 15 million ash trees. The Emerald Ash Borer-(EAB) is an exotic insect native to Asia that attacks ash trees in its larval stage. EAB feeds undetected under the bark of ash trees, disturbing natural water and nutrient flow, and ultimately killing the trees in just a few short years.
