Emerald ash borer found in Kenosha County
The tree-killing emerald ash borer has found its way into Kenosha County.
Officials say it might have been brought in illegally when an infected ash tree purchased at a suburban Chicago nursery was planted on private land north of Silver Lake.
The federal Animal and Plant Health Inspection Service is investigating.
Bob Dahl of the state ag department says there does not appear to be an active infestation within Kenosha County, but they'll check.
Federal investigators are not saying who bought or sold the tree but it violated a quarantine that's been in place in northern Illinois since the green beetle was found there in 2006.
Reports said the tree came from a remnant stock and the seller may not have known it would leave the quarantined area.
Brian Swingle of the Wisconsin Green Industry Federation calls the incident isolated but inevitable.
He said it's still more likely for the ash borer to arrive from out-of-state firewood.
Wisconsin's first confirmed emerald ash borers were found in August near Newburg in Ozaukee County. About 130 ash trees were said to be infested and the bug might have been there for several years.
