|Emerald Ash Borer (EAB) has led to the death of more than 20 million ash trees in Michigan, Ohio, Indiana and Illinois. In 2007, it was discovered in DuPage County. In 2011, it was confirmed in Clarendon Hills.
Part of the
Village’s management plan is to treat Ash trees using soil drenching with a commonly used pesticide, Imidacloprid, which goes
by the brand name “Merit” produced by Bayer Advance. This is a widely used
multipurpose insecticide that can be purchased at local hardware stores and has
been shown in some cases to help prevent the spread of EAB. Even with the
treatment, however, it may still be necessary to remove dead, dying or
dangerous Ash trees throughout the parkways.
Residents with an
Ash tree in their parkway will receive individual notices, and each parkway Ash
tree will be tagged. Treatment of the Ash trees will be completed by trained
Public Works staff and is scheduled for April and May 2012. The Village currently has
about 800 Ash parkway trees.
Village encourages residents to determine whether they have an Ash tree
in their yard and to look for signs of infestation. Trees can be
protected through EAB treatment products, though there are no guaranteed
methods to prevent EAB infestation. Questions can be directed to the Village's Public Works Department at 630-286-4750.
