Emerald Ash Borer (Agrilus planipennis Fairmaire) is an exotic beetle that feeds on ash (Fraxinus sp.) trees. Larvae feed in the phloem and outer sapwood, producing galleries that eventually girdle and kill branches and entire trees. This native of Asia was first discovered in southeastern Michigan in July 2002. On April 21, 2004, EAB was confirmed in Indiana. Since that time, this forest pest has spread throughout Indiana and the surrounding states.
If you need assistance with EAB identification or would like to report a new location, please let us know.
Indiana’s EAB Quarantine was lifted in October 2016. EAB has been detected in all 92 counties. While the restrictions on moving firewood and ash wood within Indiana have been lifted, we still encourage everyone to obtain firewood locally and burn it completely. Firewood movement into state owned property is still restricted by the DNR Property Firewood Rule. The Thousand Cankers Disease Quarantine restricts firewood from coming into Indiana from certain states. Please contact your Nursery Inspector for more information on these restrictions.
