Emerald Ash Borer

Other names: Emerald ash borer, Agrilus planipennis

Where did it come from?

Emerald ash borer was accidentally introduced into Michigan from Asia probably in shipping pallets. It has now spread throughout the United States and some parts of Canada.

Why is it invasive?

The emerald ash borer feeds on, yep, you guessed it, ash trees. Their larvae feed on the tree and can eventually kill it. The adult beetles are bright metallic green, about a third of an inch long, and present from mid-May through late July.

How do you prevent its spread?

Don’t move firewood! This invasive insect can be spread by moving infested ash firewood and logs to new areas —so purchase or cut firewood locally.
