Emerald Ash Borer
Emerald Ash Borer Beetle
The Emerald Ash Borer (EAB) is a destructive Asian beetle discovered in Ohio around 2003.  Shortly thereafter, ash trees in Worthington began showing signs of infestation.  At that point in time, there was no treatment available to fight the pest, and affected trees in the City Right-Of-Way were assessed and put on a timetable for removal.  Many trees that were in severe decline have been removed, while others receive annual assessment.  To learn more about the EAB and how to determine if your tree is affected, visit the EAB Info page.

What's Being Done
Recently, a new pesticide was developed by the Valent company. In an ongoing effort to battle the emerald ash borer, ash trees located in the City of Worthington are undergoing a second year of treatment in a five-year test program to battle the deadly beetle. Hundreds of ash trees line the streets of the City of Worthington. In order to prevent further destruction and loss of ash trees, the City of Worthington is participating in a free test program to protect the ash trees and prevent infestation by the emerald ash borer. The Worthington Department of Service & Engineering is working with Valent USA Corporation on the protection project.  Participation comes at NO COST to the City of Worthington. Over 200 trees located in the City right-of-way have been treated. Each is identified with a small ¾” by 3” aluminum numbered tag. City ash trees that have been evaluated as in good or fair condition receive the treatment. The application of the systemic insecticide “Safari” is performed by the Davey Tree Company. The root injection method eliminates contact of the insecticide to pets and people. For more information about the product, visit www.valentpro.com/safari.
