In early March 2009, McHenry Township held a special Informational Town Hall Meeting with updates on the Gypsy Moth and the Emerald Ash Borer and their impact on our community! Speakers from McHenry County talked about the county's spraying program and speakers from University of Illinois; McHenry County Extension Office presented information about prevention, identifying the problem and things homeowners can do to protect their trees. If you missed the meeting, you will find the following information helpful.
 The invasion of
Gypsy Moths has hit our community and our trees are in jeopardy. Gypsy Moth caterpillars prefer hardwood trees but will feed on many different species. After they eat the leaves, the defoliated trees go into shock and the stress may kill them.

 The
Emerald Ash Borer (EAB) is a small, metallic-green beetle that is deadly to ash trees. Its larvae burrow into the bark of ash trees, causing the trees to starve and eventually die.
The beetle is small and stealth-like in its behavior patterns and is extremely difficult to detect. If not controlled, it threatens to devastate the entire ash species in North America. There is a quarantine for northeastern Illinois in an attempt to prevent its spread.
I f you suspect EAB, please take digital
photographs of the tree and the symptoms it is expressing and email
them to:
AGR.EAB@Illinois.gov
or call the Illinois Department of Agriculture Hotline: 800/641-3934
