Tree Pest Control

Emerald Ash Borer

In September 2011 the Illinois Department of Agriculture confirmed the presence of emerald ash borer (EAB) in a trap which was located at 28th and Harrison Avenue in the Village of La Grange Park. Due to this confirmation the Village is now on the Illinois EAB Confirmed Infested Locations list. View the EAB Detection Map 2018 (PDF).

The Village of La Grange Park is very active in preventing and mitigating tree pests. Residents can help by monitoring their parkway and private property trees for signs of infestation or disease due to tree pests and have those trees removed. Look for dead and dying branches at the top of the tree’s crown and adult beetles emerging from trees will leave a small, one-eighth inch diameter, unique “D” shaped exit hole. Other EAB signs and symptoms can be viewed at the Morton Arboretum website.

What You Can Do to Help With EAB

Do not move firewood. The Emerald Ash Borer can easily be transported in ash logs. Purchase firewood locally, within county, from a known source. Be sure to use all the firewood in the cold months so that no hidden EAB larvae or adults can survive on logs left through the spring. There are both state and federal quarantines in place that restrict the movement of ash logs, branches or other material in certain areas. The entire state of Illinois is under a federal quarantine which restricts the movement of regulated articles across the state line. Additionally an internal state quarantine is in effect for the 18 northeastern most counties within the state.

If you think you have EAB please contact Public Works at 708-352-2922. The Village currently monitors tree pests. The National EAB Hotline number is 866-322-4512.
