Ohio Department of Agriculture Emerald Ash Borer Program

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 education in an attempt to protect the state’s more than 3.8 billion ash trees. The pest has since spread from the initial detection in near Toledo to its present distribution in 56 counties. Because the pest has been found throughout most of Ohio, including 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, 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.

To date, infestations have been identified in Allen, Ashland, Auglaize, Butler, Clark, Clermont, Clinton, Cuyahoga, Darke, Defiance, Delaware, Erie, Fairfield, Franklin, Fulton, Geauga, Greene, Hamilton, Hancock, Hardin, Henry, Huron, Lake, Lawrence, Licking, Logan, Lorain, Lucas, Mahoning, Marion, Medina, Mercer, Miami, Montgomery, Morrow, Ottawa, Paulding, Perry, Pickaway, Pike, Portage, Putnam, Richland, Sandusky, Scioto, Seneca, Shelby, Summit, Trumbull, Union, Van Wert, Warren, Wayne, Williams, Wood, and Wyandot counties.

If you are located in a county not listed above and believe you have EAB in your area, please contact ODA at 1-888-OHIO-EAB. Otherwise, please visit the Ohio Stat University Cooperative Extension at http://ashalert.osu.edu for more information.
