Plant Health Division - Emerald Ash Borer


Adult Emerald Ash Borer

Emerald Ash Borer (Agrilus Planipennis), an ash tree-killing insect from Asia, was identified in Ohio in 2003. The department has been battling the pest through detection, regulation, and public outreach in an attempt to protect the state's more than 3.8 billion ash trees over the past decade. The pest has since spread from the initial detection in near Toledo to nearly all other parts of the state. Because the pest is established throughout most of Ohio, including Cincinnati, Cleveland, Columbus, Dayton and the Wayne National Forest, there are no longer quarantine regulations in place for emerald ash borer within the state. Despite the fact that the Ohio quarantine has been lifted, to prevent the spread of EAB and other pests, it is still recommended that Ohioans continue to exercise caution when moving firewood.

EAB kills ash trees within three to five years of infestation. Adults are dark metallic green, 1/2 inch in length and 1/8 inch wide, and fly only from mid-May to September. Larvae spend the rest of the year developing beneath the bark. If you believe your trees to be infested and would like to learn more about treatment or removal of your ash trees, please visit the Ohio State University Cooperative Extension Program’s EAB website at http://ashalert.osu.edu or go to http://www.emeraldashborer.info for more information.

If you have questions about interstate movement of ash logs or lumber please contact USDA - APHIS Ohio EAB Program at (614) 322-4700.
