What is the Emerald Ash Borer (EAB) and what does it do?
This Asian beetle, discovered in 2002 in southeastern Michigan and Windsor, Ontario, infests and kills North American ash species (Fraxinus sp.) including green, white, black and blue ash, and their cultivars. The larval stage of EAB feeds under the bark of trees, cutting off the flow of water and nutrients. Infested trees gradually die over a 2-4 year period.
