Emerald Ash Borer in Winnetka

September 11, 2006
A fourth location for emerald ash borer (EAB) in Illinois, the third in northern Cook County, was discovered by an arborist during mid-August. The arborist submitted ash branches with galleries symptomatic of this borer to the Illinois Department of Agriculture (IDA) Des Plaines office. The samples were sent on to the EAB headquarters in Brighton, Michigan, where a positive confirmation of EAB larvae was made.


EAB is a destructive, nonnative pest that feasts on ash trees. The first case was detected in June in Kane County. Since then, the insect was also found in Wilmette and Evanston. A quarantine zone has been established around 51 square miles of Kane County to contain the spread there. Once the survey in Cook County is complete, the quarantine will be amended to reflect the infestation in Wilmette, Evanston, and Winnetka.


Anyone who suspects a tree has been infested is urged to first contact their local forestry department or county Extension office. The Illinois Department of Agriculture also will offer a toll-free hotline at (800)641-3934 for Extension-confirmed infestations.
