Native to Asia, the Emerald Ash Borer is an exotic beetle that was unknown in North America until June 2002 when it was discovered as the cause for the decline of many ash trees in southeast Michigan and neighboring Windsor, Ontario, Canada. It has since been found in several states from the east coast spanning across the midwest and in June 2006, we discovered that it had taken up residence in Illinois.
