    Open house on spraying plan Feb. 24 at the park

    BARABOO, Wis. -- Aerial spraying to control gypsy moth caterpillars is planned for 85 acres at Mirror Lake State Park this spring, including the Cliffwood and Sandstone Ridge campgrounds, boat landing picnic area, and the Echo Rock Trail areas. The spraying will be done in order to reduce gypsy moth populations and prevent the caterpillars from defoliating trees in the treatment area. The spraying will be coordinated through the Wisconsin Department of Natural Resources Gypsy Moth Suppression Program.

    A small, low-flying airplane will apply "Foray," an insecticide made from the naturally occurring bacteria Bacillus thuringiensis kurstaki (btk), beginning early in the morning. The spraying will occur sometime between the middle of May and early June, depending on weather conditions and caterpillar development.

    DNR staff will host an open house meeting to share information on the spray program. The open house will be held from 9 to 10 a.m. on Wednesday, Feb. 24 at the Mirror Lake State Park Office, E10320 Fern Dell Road, Baraboo. Questions can be directed to DNR Forest Health Specialist Mark Guthmiller by calling 608-275-3223 or Park Manager Becky Green by calling 608-254-2333.

    The gypsy moth is a serious forest and urban pest that was introduced into the United States from Europe in the 1860s. The gypsy moth population had a slight increase in parts of south central Wisconsin this past year with isolated areas with populations reaching damaging levels. Within parts of Mirror Lake State Park the gypsy moth population has reached the point that the caterpillars may kill trees by eating all of their leaves during May and June. Aerial spraying will prevent this damage and will avoid other adverse effects such as nuisance caterpillars and skin rashes resulting from direct exposure to the caterpillars.
