NEW BERLIN, WI (WTAQ) - New Berlin is the latest Wisconsin community to have the tree-killing emerald ash borer.
Officials in the Milwaukee suburb said the green beetle has been found at four places -- a tree and three traps.
The "New Berlin Now" news Web site said the ash borer was first discovered in New Berlin and nearby Waukesha last week. It's now reported in four communities in Waukesha County, including Oconomowoc and Mukwonago.
New Berlin Mayor David Ament called the spreading of the emerald ash borer "inevitable."
New Berlin city forester Paul Fliss says it's expensive to treat ash trees. He advises homeowners and businesses to decide which trees they really want to keep, and their work to start treating them now.
In the U.S., the ash borer was first discovered near Detroit 11 years ago. It has since spread to Canada and over a dozen states.
Wisconsin had first confirmed infestation in 2008. Eighteen Wisconsin counties are under quarantine for the ash borer. The new discovery involves an area that's been under quarantine for some time.
