Emerald Ash Borer Quarantine

April 30, 2008

First discovered in Illinois in June 2006, emerald ash borer (EAB) has since been confirmed in communities within Kane, Cook, LaSalle, and DuPage counties. A quarantine has been issued for the northeasternmost area of the state in an attempt to prevent its spread. EAB-quarantine-provision compliance is urged for all contractors and public works officials around the state, especially those within the EAB-quarantined area in all or parts of the 18 northeasternmost counties of the state.

The quarantine prohibits the removal of the following items from regulated areas:

The emerald ash borer in any living stage of development.
Ash trees of any size.
Ash limbs and branches.
Any cut, nonconiferous firewood.
Bark from ash trees and wood chips larger than 1 inch from ash trees.
Ash logs and lumber with either the bark or the outer
1 inch of sapwood, or both, attached.
Any item made from or containing the wood of the ash tree that is capable of spreading the emerald ash borer.
Any other article, product, or means of conveyance determined by the Illinois Department of Agriculture to present a risk of spreading the beetle infestation.
Waste haulers must cover regulated material from an infested area during transport through EAB flight season, which is from June through August.

Anyone convicted of moving prohibited items from the quarantine area without prior certification by an Illinois Department of Agriculture nursery inspector may be fined up to $500.

How the emerald ash borer arrived in Illinois is unknown, but the department suspects it may have been transported here in contaminated firewood. To avoid the accidental introduction of the beetle to new areas, the department encourages lllinoisans to purchase only locally grown nursery stock and locally cut firewood. Anyone who suspects a tree has been infested is urged to contact the department or their village forester for a consultation.

The entire counties of Boone, Cook, DeKalb, DuPage, Grundy, Kane, Kankakee, Kendall, Lake, LaSalle, McHenry, Putnam, Will and Winnebago are under quarantine, as well as the following.

The emerald ash borer is difficult to detect, especially in newly infested trees. Citizens should watch for metallic green beetles about half the diameter of a penny on or near ash trees that are showing signs of disease or stress. Other signs of infestation in ash trees include D-shaped holes in the bark of the trunk or branches and shoots growing from its base. Anyone who suspects a tree has been infested is urged to contact a county Extension office. For more information, visit www.IllinoisEAB.com.
