Plant Health Division - Emerald Ash Borer


Adult Emerald Ash Borer

Emerald Ash Borer (Agrilus Planipennis), an ash tree-killing insect from Asia, was first identified in Ohio in 2003. The pest has since spread from the initial detection near Toledo to all of the counties in the state. Because the pest has established itself throughout all of Ohio, in July 2011, ODA lifted the 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 and other ash materials. Quarantines for other pests still in place in Ohio are Gypsy Moth, Walnut Twig Beetle (TCD), and Asian Longhorned Beetle. Maps can be found on the ODA website.

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 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.




Emerald Ash Borer FAQ's

Q. Can someone from ODA come look at my tree?

A. The Department of Agriculture is not currently sending officials out to look at suspected emerald ash borer damage. It is recommended that homeowners contact a certified arborist to have their trees inspected, and choose an appropriate course of action based on this inspection.


Q. Can I save my ash tree?

A. If you have no signs of EAB infestation, (crown dieback, bark splitting, suckers, woodpecker damage, D-shaped exit holes, etc.) then treatments may protect your tree. Refer to the website listed above under “Insecticide Options for Controlling EAB”.


Q. Is there any financial assistance for homeowners with infested Ash trees?

A. There are currently no financial assistance programs available through the Department of Agriculture to assist with tree removals or insecticide applications.


Q. What can I do with firewood generated from tree removals?

A. Firewood can be utilized by the homeowner for campfires, fireplaces, heating, etc. Homeowners are encouraged to burn the wood locally (within your county), as quarantines for other pests are still in place. Maps of Gypsy Moth, Walnut Twig Beetle (TCD), and Asian Longhorned Beetle Quarantined counties can be found on the ODA website.


Q. Do I need to report an EAB infestation on my tree?

A. Since EAB has established itself in all of Ohio you do not need to report any findings.
