2023 Treatment Areas

The Minnesota Department of Agriculture (MDA), in collaboration with federal, state, and local partners, are proposing to treat spongy moth populations at four sites in the summer of 2023 using a mating disruption product. Spongy moths are an invasive insect, and our state monitoring program found a high number of moths in these areas.
