The Emerald Ash Borer (EAB) is an Asian beetle that moved into the south-east corner of Michigan some time in the early 1990's. It's larvae feed on the cambium or conductive tissue just under the bark of ash trees. They only feed on ash trees and will usually kill the infested tree within 1 to 5 years. Though the infestation was first discovered in 2002 in the Detroit area, this aggressive beetle is now found throughout the lower peninsula of Michigan and in 13 additional States and in two Canadian provinces.

In 2004, voters in Bay County approved the renewal of the Gypsy Moth Millage with the inclusive language of "other invasive, non-native pests, such as the Emerald Ash Borer (EAB)". This will allow the Gypsy Moth Suppression program to address the problem of the EAB when it is found in Bay County. The EAB Plan of Action outlines the actions which will be undertaken by the Bay County Gypsy Moth Suppression Program with regard to the EAB.

In 2005, the Emerald Ash Borer was found in southern Bay County.
