WEST BEND, Wis. (WTAQ) - Record-warm temperatures have caused the tree-killing emerald ash borer to appear earlier than normal in Wisconsin this year. State agriculture officials say adult beetles and larvae have been found at a park in West Bend for the first time.

And new adult beetles showed up 16 days ahead of last year in a previously-infested area at Newburg in Washington County. A new infestation was also found at Victory in Vernon County, where a major outbreak from the past has spread into neighboring Minnesota.

There will be no new restrictions on ash products as a result of the West Bend discovery. That’s because the city was already part of a quarantine zone resulting from the Newburg outbreak.

Quarantines are now in effect in Brown, Crawford, Fond du Lac, Kenosha, Ozaukee, Milwaukee, Racine, Sheboygan, Vernon, Washington, and Waukesha counties. In general, firewood and ash products cannot be taken outside those counties unless the sellers certify that they’re free of the ash borer.

Meanwhile, the state will finish placing 8,700 traps in ash trees this week. They’ll start checking them next week.
