Emerald Ash Borer Found in Trempealeau County - WXOW News 19 La Crosse, WI – News, Weather and Sports |

Trempealeau, WI (WXOW) - A single adult emerald ash borer has been captured in a trap in Perrot State Park in Trempealeau County.

The Ash Borer is a non-native, invasive species that feeds on the wood under the bark of ash trees.

The beetle is responsible for killing tens of millions of ash trees across the United States since 2002.

The Wisconsin Department of Agriculture, Trade and Consumer Protection says Trempealeau  County will be placed under quarantine to help stop the spread of the beetle.

That means hardwood firewood, regardless of tree species, cannot leave the quarantine area.

The tree-killing Emerald Ash Borer has been confirmed in 12 other Wisconsin counties: Brown, Crawford, Kenosha, La Crosse, Milwaukee, Ozaukee, Racine, Rock, Vernon, Walworth, Washington, and Waukesha.

It has also been discovered in Houston and Winona Counties in Minnesota.
