2022 Treatment Areas

The Minnesota Department of Agriculture (MDA), in collaboration with federal, state, and local partners, treated gypsy moth populations at four sites in the spring/summer of 2022. Gypsy moths are an invasive insect, and our state monitoring program has found a high number of moths in these areas.

Aerial Treatment Applications

The MDA contracts aircraft to apply aerial treatments in Minnesota. Aircraft begin flying shortly before sunrise because weather conditions are most ideal early in the morning for treatment application. The aircraft flies over the treatment block, going back and forth in a zig zag like pattern. The aircrafts fly very low (about 50 feet above the treetops) and are very loud. Residents may be awakened by the noise of the low-flying aircraft.
