Emerald Ash Borer

What are Emerald Ash Borers?

Native to Asia, this species was found in Michigan in 2002 but could have been around since the mid-1990s. Emerald Ash Borer (EAB) was likely brought to North America by accident in wood shipping pallets with the bark still attached.

Ash trees typically die within 3-5 years after being infested by EAB. All native Ash tree species are susceptible to infestation, including green, white, pumpkin, blue, and Carolina ash.

EAB can be found in most eastern US states and is found moving west.
