What is Emerald Ash Borer?
Emerald Ash Borer (EAB) is an invasive pest from Asia that has been threatening the ash tree population throughout the United States since it was first discovered in Michigan in 2002. EAB was first detected in Vermont in 2018 and has been spreading through the state ever since. Through a combination of natural spread and human activity, EAB is now found throughout the United States and Canada.
EAB has predominantly targeted green, black, and white ash trees. Depending on the size and health of the tree, it can take an infested tree anywhere from 1-4 years to die.
