The tree-killing emerald ash borer has been discovered in the southwestern corner of Schaumburg.

Village officials said the Illinois Department of Agriculture confirmed the infestation earlier this month. The village didn't give a specific location or say how many trees were found to be infested with the metallic green pests, but did indicate that a third of the village's publicly owned 36,000 trees are ash trees.

The village is developing a plan to deal with the invasive bugs, which will include removal of infested trees. Emerald ash borer larvae feed on ash tree trunks, cutting off their ability to transport nutrients and eventually killing, usually after a few years.

Symptoms can include the tree canopy losing fullness, D-shaped exit holes on the trunk, shoots sprouting from the trunk and S-shaped larval galleys under the bark.

The ash borer was first discovered in North America in 2002 and has since killed 25 million trees. It's been in Illinois since 2006 and has been confirmed in several towns in Kane, Cook, Lake, McHenry and LaSalle counties.

Some treatments are available, but they can be expensive and none has been shown to be 100 percent effective.

Residents with questions should call the public works and engineering department at (847) 895-7100.
