The Village began treatment for emerald ash borer on parkway trees in early July. The application process consists of an injection of the pesticide into the base of the tree with a product known as Tree-Age. Residents are asked to report to Public Works, 708-246-1800, Ext. 200, any ash trees showing emerald ash borer symptoms. The most common symptoms are branch dieback, bark splits, suckering and D-shaped emergence holes. If residents intend to treat their own parkway trees, the Village also asks that it be notified so it can keep a record of treated trees. Any tree treated by the Village or a private resident does not guarantee the tree will not be removed
by the Public Works Department. Any parkway tree that is deemed a public safety hazard or a vector for the further spread of the emerald ash borer may be identified for removal by the Village forester. Full information regarding the application process, the map of the proposed application locations and a brochure on emerald ash borer can be found here.
