Minnesota Department of Agriculture Takes Action to Slow Spread of Spongy Moth

The Minnesota Department of Agriculture (MDA) is launching strategic aerial treatments to slow down the spread of the spongy moth, a destructive tree pest threatening the state. Beginning on July 14, targeted areas in Carlton County and Duluth will be treated to minimize the moth's impact on forest health and safeguard communities.

The treatments will involve the application of an environmentally friendly substance that disrupts the mating patterns of male moths, reducing their ability to find females for mating and resulting in fewer caterpillars attacking trees.

Covering approximately 14,000 acres near Holyoke along the Wisconsin border, the Carlton County treatment area, along with three areas around Duluth (Duluth East, Duluth West, and Midway) totaling about 12,000 acres, will be the focus of these efforts.

The MDA, in collaboration with the U.S. Forest Service, will utilize low-flying yellow planes to apply the mating disruption product. These planes will fly above the treetops at an altitude of approximately 150 feet, ensuring precise and effective coverage.

The treatment poses no harm to humans, animals, birds, or other insects, emphasizing the commitment to protecting forest ecosystems, preserving property values, and supporting Minnesota's vibrant tourism industry.

The MDA has established a "Report a Pest" information line at 1-888-545-MOTH (6684) for timely pest information dissemination. residents can receive updates on treatment progress by texting "MNMDA MOTH" to 66468 for text notifications or by texting "MNMDA MOTH [email address]" to 66468 for email notifications.

Minnesota is taking proactive measures to protect its Eastern forests from spongy moths, which have caused millions of damages. They are using an innovative aerial approach to safeguard forests from their destructive impact. Cooperation is crucial to prevent unintentional spread, and avoiding transporting firewood or other items carrying moth eggs is essential.

This will protect Minnesota's natural beauty for generations to come.
