The Illinois Department of Agriculture has expanded the Emerald Ash Borer quarantine zone to include 64 miles of northern Cook County, including the portion of the Village north of Touhy Avenue.  The purpose of the quarantine is to prevent the beatle from spreading throughout the State.  The quarantine prohibits the movement of wood outside of the established zone.  Individual homeowners are not responsible for the disposal of wood when work is performed by private landscapers or tree removal firms.

The Emerald Ash Borer (EAB) is a very small but very destructive beetle.  Metallic green in color, its slender body measures 1/2 inch in length and 1/8 inch wide.  The average adult can easily fit on a penny.  Beetles are usually only visible from May - July.  For the most updated EAB information, please visit Michigan State University's Emerald Ash Borer website or the Morton Arboretum website.

Emerald Ash Borer Beetles ONLY infest ash trees.  The Emerald Ash Borer has not been found in Lincolnwood.

This beetle is currently known to be responsible for the death or decline of more than 15 million ash trees in and around Detroit.  EAB was recently discovered in Illinois, first in Kane County and then in Wilmette on July 13, 2006.  Since then, infestations have been confirmed in Evanston and Winnetka.  The Village strongly advises residents to continually check their trees for the early signs of EAB infestation.  If your tree is infested or you think it may be infested, please contact Public Works at (847)-675-0888.

Signs and Symptoms

It is difficult to determine whether or not an ash tree is infested or not infested with EAB because tree decline is usually gradual.  Symptoms include:

Treatments

There are currently no approved treatments for EAB.  Every EAB-infested tree will die.  Treatments may prolong the life of a healthy ash tree but will not prevent the tree from becoming infested.
