Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. It probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. Because ash trees (Fraxinus spp.) in North America have no immunity to the insect, EAB has the potential to wipe out more than 700 million ash trees in Michigan. Since 2002, it has killed more than 30 million ash trees in southeastern Michigan alone. State and federal agencies in Michigan, and researchers in Michigan universities, are working to stop EAB from spreading. This includes the initiation of quarantines to stop the movement of infested ash wood and wood products, research to understand the pest's life cycle and what methods and strategies can control or eradicate it and development of educational and informational materials to help communities detect and deal with EAB infestations.
Please be advised that Michigan has revised its Emerald Ash Borer internal quarantine effective 2/10/16.
If you live in the Lower Peninsula, you no longer need to report EAB. If you need additional information, please use the contact information below.
Four new counties are quarantined by this revision. (Baraga, Dickinson, Marquette and Menominee)
