Before gypsy moth treatments begin, local officials and the public are notified of our proposal as part of an environmental assessment process. Information is shared to explain what is proposed and why, and to allow citizens to have their comments included in the assessment. We emphasize that this is a proposal. The final treatment decision comes at the end of this process, when the environmental assessment is signed by representatives from the U.S. Forest Service, the USDA Animal & Plant Health Inspection Service (APHIS), and other cooperating agencies.

2021 Treatments

Comments on the 2021 proposed treatments were accepted through April.

The USDA APHIS Environmental Assessment and the USDA Forest Service Environmental Assessment have been completed and approved. All proposed 2021 treatments will be implemented.

You can contact Kimberly Thielen Cremers kimberly.tcremers@state.mn.us to receive a copy of the environmental assessments.

U.S. Postal carrier routes are used to identify residents within the proposed treatment area, and the MDA attempts to notify everyone in the area by mail. Because treatments are weather dependent, exact spray dates are estimated. Exact dates and times will be announced as soon as possible through local media, the MDA's toll-free telephone line (1-888-545-6684), and on this website. Local law enforcement, health departments, schools, and hospitals will also be notified.
