The emerald ash borer (EAB) quarantine helps to limit the human assisted spread of the insect by restricting the movement of certain items that may harbor one of the life stages of EAB. Some examples of items that are commonly moved by people but are now forbidden from leaving the quarantine area include ash nursery stock, ash logs, ash tree trimmings, ash mulch, or any species of hardwood firewood. Allowances are made for businesses that deal with these products provided that they’ve been inspected and have agreed to comply with specific safe handling procedures.

Since 2008, emerald ash borer has been confirmed in 13 Wisconsin counties. Two additional counties – Sheboygan and Fond du Lac – are under quarantine because of their proximity to known infestations, but no emerald ash borer has been detected in either of those counties.

The list of infested counties in Wisconsin includes: Brown, Crawford, Kenosha, La Crosse, Milwaukee, Ozaukee, Racine, Rock, Trempealeau, Vernon, Walworth, Washington and Waukesha.
