WAUWATOSA, WI (WTAQ) - The tree killing emerald ash borer has made its first appearance in the Milwaukee suburb of Wauwatosa.
An arborist found the destructive beetle in October, but officials didn't say anything about it until Friday because they could not find any trees that the latest bug had damaged.
There were several reports of tree damage from the Wauwatosa ash borer -- but none could be confirmed.
Wauwatosa joins several other communities where the emerald ash borer has been found, including the city of Milwaukee. Milwaukee County is already under a state quarantine, in which ash materials can only be shipped out if they're found by the Agriculture Department to be disease free.
18 other counties have similar quarantines since the ash borer first arrived in the state in 2008.
