The Minnesota Department of Agriculture (MDA) is getting ready to conduct aerial treatments across five counties—Aitkin, Carlton, Itasca, Pine, and St. Louis—to stop the spread of spongy moth, a harmful forest pest. These treatments are expected to happen between July 16 and 22, beginning as early as 6:30 a.m. each day, depending on the weather.
In total, 24 treatment sites covering about 83,760 acres will be managed. Residents can view a map on the MDA website or use an interactive map to see if their address is in a treatment area.
The treatment method is known as mating disruption. A non-toxic, waxy, food-grade material containing spongy moth pheromones will be applied by low-flying yellow planes. “This makes it difficult for the male spongy moths to find females, reducing mating success.” Fewer moths mean fewer caterpillars to damage trees next year.
The aerial work is a joint effort between MDA and the USDA Forest Service. The treatment does not harm humans, pets, birds, or other insects. It helps maintain forest health and supports tourism and property values.
Unlike some pest programs that have been delayed by federal funding cuts, this operation is proceeding as planned. However, MDA is monitoring how future funding may affect long-term pest control.
To keep communities updated, MDA has set up a Report on a Pest Info Line at 1-888-545-6684. Press 0 to speak with someone directly. Residents can also sign up for text or email notifications through the MDA's Spongy Moth Map webpage.
Spongy moths are among the most damaging forest pests in the U.S. They prefer trees like oak, poplar, and birch and can cause large-scale defoliation. Movement of firewood and other items with eggs can spread to the moths unknowingly.
