The Minnesota Department of Agriculture (MDA) is preparing to conduct aerial management operations to slow the spread of spongy moths in Northeast Minnesota. The activities are expected to take place from July 14 to July 17, depending on local weather conditions. Flights may begin as early as 6:30 a.m. and continue throughout the day.
A total of 16 management sites covering approximately 36,734 acres are in Aitkin, Carlton, Pine, and St. Louis counties. Residents can view site maps on the MDA website. They can also check whether their property falls within a management area through the interactive map.
The MDA will use a management technique known as mating disruption. This method involves the aerial application of a nontoxic, waxy, food-grade substance containing pheromones. These pheromones confuse male spongy moths, making it difficult for them to locate female moths. As a result, mating rates decrease, leading to fewer caterpillars hatching in the following season.
The treatment will be applied by low-flying yellow planes contracted by the U.S. Department of Agriculture’s Forest Service as part of a joint project with the MDA. Officials have stated that the product is safe for humans, pets, wildlife, birds, and beneficial insects. The program aims to protect forests, preserve property values, and support Minnesota’s tourism industry.
To keep residents informed, the MDA has established an information hotline at 1-888-545-6684. The latest updates regarding management dates and flight schedules will be available through this service. Residents can also monitor management progress through the tracking map and find educational resources about spongy moths on the MDA website.
People interested in receiving direct notifications can sign up for text or email alerts through the Spongy Moth Management Map. Users can select management areas outlined in blue and follow the notification sign-up option.
Spongy moths are among the most destructive tree pests in North America. They can cause severe damage to forests by feeding trees and weakening trees. By carrying out these aerial management efforts, Minnesota hopes to slow down the spread of this invasive pest and protect valuable forest resources for future generations.
