Emerald Ash Borer
What is the Emerald Ash Borer?

The Emerald Ash Borer (EAB) is a non-native (invasive) insect that was introduced into the United States by imported wood products from Asia.  The EAB has infested and killed over 25 million ash trees in the United States.  The EAB’s larvae enter an ash tree and feed just under its bark eventually killing the infected tree.  The first known EAB infestations were documented in Michigan in 2002.  Since then the EAB has slowly spread throughout the eastern United States.

Where is EAB in Kentucky?

Currently there are 29 counties in Kentucky that are under quarantine for EAB.  These counties include:  Anderson, Bell, Boone, Bourbon, Boyd, Boyle, Bracken, Campbell, Carroll, Fayette, Franklin, Gallatin, Garrard, Grant, Greenup, Hardin, Harrison, Henry, Jefferson, Jessamine, Kenton, Oldham, Owen, Pendleton, Pike, Rockcastle, Scott, Shelby, Trimble, Whitley, and Woodford.





What is KYTC Doing to Help Prevent the Spread of EAB?

KYTC is being proactive to help prevent the spread of EAB.  In the five KYTC Highway Districts that have been affected by EAB, a program for actively treating ash trees with insecticide to help prevent further EAB infestation has been implemented.   Although KYTC cannot treat all ash trees on its properties, it is actively treating prized mature individual ash trees and mature stands of ash trees located in KYTC roadway right of way or located at one of its managed properties.

Another measure that KYTC has implemented to help prevent the further spread of EAB is to prohibit the movement of felled trees from a KYTC project or from a KYTC maintenance activity that occurs in one of Kentucky’s quarantined counties.



 How can I help prevent the further spread of EAB?

The quarantine for EAB prohibits regulated articles from being moved outside the quarantined area without a certificate or limited permit.   For detailed updated information regarding these restrictions, please visit the University of Kentucky’s College of Agriculture at:


The most important thing you can do to prevent the further spread of EAB is not to transport firewood from a quarantined to an un-quarantined county in Kentucky.
