The Illinois Department of Agriculture
confirmed the presence of the Emerald Ash Borer (EAB) in La Grange. The insect was first discovered on the 0-100 block of South Spring Avenue in August 2009, where an adult EAB beetle was detected on purple sticky traps. More recently, a tree was discovered near the intersection of Cossitt and Stone Avenues infested with the EAB.
The EAB was first discovered in North America in 2002 in the Detroit and Ontario areas. Since then, it has killed tens of millions of ash trees in the Midwest and Mid-Atlantic states. More locally, the EAB has been found in Chicago, Oak Park, and Burr Ridge. La Grange is among 62 other communities in Cook County where the EAB has been confirmed.
