Emerald Ash Borer

The emerald ash borer (EAB) is an exotic beetle that was discovered in southeastern Michigan in the summer of 2002. Since its discovery, EAB has killed tens of millions of ash trees. Emerald ash borer is now established in Missouri and virtually every state north and east. In May, 2015, EAB infestations were confirmed in the City of Liberty. Every ash tree in our area is now at risk of being attacked and killed in the near future.

If you have an ash tree on your property, you should become informed of your options. Without periodic insecticidal treatments, all ash trees in our area WILL be killed by EAB. Now is the time to develop a plan of action to ensure that you are prepared. A proactive plan identifies individual trees that will be preserved or removed, as well as a planting plan to replace the trees that will eventually be lost.

Learn About EAB

To learn more about the EAB, signs and symptoms of infestation, and how to plan ahead for its inevitable arrival, visit the University of Missouri Extension website on the EAB or emerald ash borer. View this video to determine if you have an ash tree with symptoms of EAB infestation.

The most effective and environmentally compatible treatment option involves the injection of a specific insecticide into the tree by a qualified professional. View this video on what to expect from an EAB injection treatment. Learn more about How to Hire an Arborist or Tree Service.

The plan includes treatment of the highest value trees and removal and replacement of all others.
