The Village’s Arborist found the Emerald Ash Borer (EAB) on Ash trees located within the Village.  Their presence has since been confirmed by the Illinois Department of Agriculture.

What is the Emerald Ash Borer?

The Emerald Ash Borer, depicted to the left, is an invasive beetle that feeds only on Ash trees.

Village's Response

Although this is the first confirmed sighting in the Village, Public Works had already begun a program to protect some of the Village’s large, valuable Ash trees by injecting a systemic insecticide.  The insecticide is tested by the United States Department of Agriculture to treat Ash trees and help fight infestation of the EAB.

Public Works is re-inspecting of all the Ash trees on public property to determine any further infestation and damages.  The results of the inspections will determine the scope of the Village’s response.  Trees identified as seriously infested will be removed and disposed of in accordance with the Illinois Department of Agriculture guidelines for Ash debris disposal. 

Replacement Plans

Replacements will not be planted until the fall and will consist of other species to avoid further loss due to the EAB.  Although the Village is committed to doing it’s best to help control this pest, it realizes that control, not eradication, is the best that we can hope for in the fight against the EAB.

Public Meeting

A public meeting is planned for Wednesday, June 17 at 6:30 p.m. at the Lake in the Hills Village Hall.  The meeting will provide information concerning the impacts of the EAB and discuss the Village’s response to this pest.  Village residents and anyone concerned are welcome to attend this meeting.
