Two central Wisconsin counties are the latest to be quarantined for the emerald ash borer.
That's after the tree-killing bug was found in Stevens Point for the first time. Quarantines in Portage and Wood counties bring the total number to 41 counties where wood products' businesses must certify with the state that their merchandise is ash-borer-free before it can be sent to non-quarantined counties. State agriculture official Brian Kuhn says paper mills in the Stevens Point and Wisconsin Rapids areas can still received wood from quarantined counties -- but they must follow the rules for shipping out wood products. The tree-killing ash borer was first found in Wisconsin in 2008 northwest of Milwaukee. Kuhn says Wood County was included in the latest quarantine because it's likely that the ash borer is present at low levels which are hard to detect.
