MADISON, WI (WTAQ) - State agriculture officials are renewing their battles against the leaf-killing gypsy moth, and the tree-killing emerald ash borer.
Aerial spraying will resume in late May, and officials will use the non-toxic BTK to go after the gypsy moths.
The low-flying planes will begin spraying in southern Wisconsin and move northward, ending in July or August. 25 counties are being targeted this year, generally in the western third of the Badger State.
Spraying updates will be available online at Gypsymoth.Wi.Gov.
Meanwhile, federal and state workers are putting up 1,100 traps around the state to check for the presence of the emerald ash borer. Most traps will be placed in counties where the beetle has not made its presence known.
The ash borer has caused tree damage in 13 Wisconsin counties, and some communities may put up traps to check for any new infestations.
People are asked not to touch the purple-trap boxes.
The emerald ash borer has been confirmed in Brown, Crawford, Kenosha, La Crosse, Milwaukee, Ozaukee, Racine, Rock, Trempealeau, Vernon, Walworth, Washington, and Waukesha counties.
