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.
