Emerald Tree Care LLC’s Illinois Ash Borer Treatment Program was launched in 2008 after our successful Ohio and Michigan programs were already underway starting in 2002.  Our decision to come to Illinois was a direct response to the 2006 discovery of the non-native pest in Kane County, one of the counties on the outskirts of Chicago.

Now in our fourth year of treating in the Illinois area, the Emerald Ash Borer’s presence has grown from only three cities that had confirmed the insect’s presence to over 150 cities confirmed.  To be honest, I suspect nearly 200 cities will have confirmed the insect by year’s end.  An interesting fact: it is impossible to confirm this insect in a tree until it has been in it for 2-3 years.  In most of these confirmed locations in Illinois, it has been determined that the Emerald Ash Borer has most likely been there for 3-4 years.

If you follow my train of thought, then the REAL map of where this insect was four years ago looks very much like the “confirmed” map we know of today!  And where this insect is today won’t show up on any map for another 3-4 years.  More than likely, at this very moment, the Emerald Ash Borer is probably present in nearly every community in every county in Illinois.  We just haven’t found it yet!


If the Emerald Ash Borer has been confirmed within 15 miles of your home, then you need to start considering a professional treatment program.  Wayne A. White, Board Certified Master Arborist of Emerald Tree Care, LLC, has treated more ash trees since 2002 than anyone else. As a result, I have more ash trees alive today than any other arborist in America!
