4th Emerald Ash Borer Infestation Found in Illinois

WINNETKA, Ill. – The Illinois Department of Agriculture (IDOA) today confirmed the emerald ash borer (EAB) has been located in Winnetka.
The infestation was discovered by an arborist late last week while assisting in an extensive survey initiated as a result of infestations in Wilmette and Evanston. The arborist submitted ash branches to the IDOA Des Plaines office with galleries symptomatic of EAB presence. 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, non-native 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.
