DNR program for suppression of outbreaks

The Wisconsin Department of Natural Resources (DNR) offers a voluntary program to suppress gypsy moth outbreaks using a state-organized aerial insecticide treatment (details of State of Wisconsin Natural Resources Board Rule NR47). Participation in the aerial spray treatment allows communities and individuals to manage gypsy moth outbreaks at a lower cost than would be possible for privately arranged treatments. The USDA Forest Service cost shares the expense of these aerial treatments along with the associated administrative costs. The Forest Service may provide up to 50% of the costs where landowners own less than 500 acres, up to 33% of commercial forest land where landowners own more than 500 acres, and up to 25% of treating publicly owned land. The county is responsible to collect the balance of the expense of treatment and the associated administrative work and they may raise those funds by any means appropriate short of applying for a second federal grant.

The DNR’s suppression program is offered to landowners through counties. Participating counties provide a local coordinator who acts as a contact for the public and the DNR and is responsible for a number of duties at the local level. To apply for the suppression program, landowners should check the following list of county coordinators or contact their county government. Areas proposed for treatment are determined in the fall (September, October, and November) based in part on the density of egg masses. Applications from counties must be postmarked by the first Friday in December to be considered.
