On Tuesday, the Minnesota Department of Agriculture (MDA) will treat areas in Cloquet and Duluth to prevent gypsy moth infestations. Officials plan to conduct the aerial treatments as early as 5:00 a.m. in Duluth followed by Cloquet. According to the MDA, the treatments will take approximately two-and-a-half hours to complete both areas. The process should be complete by 10:00 a.m.

Gypsy moths are among America's most destructive tree pests, having caused millions of dollars in damage to Eastern forests. The moths are now threatening Minnesota.

MDA says treatment in Duluth will cover approximately 630 acres in the New Duluth Neighborhood, from House Street to the St. Louis River and extend west of Commonwealth Avenue/Highway 23. The Cloquet site encompasses approximately 400 acres of the Sappi mill property. 

A low-flying airplane will be traveling up to a half mile outside the treatment areas. The MDA apologizes for any inconvenience caused by the noise of the plane.

This is the first of two aerial applications of Foray/Bacillus thuringiensis var. kurstaki (Btk) over each area. The second will take place in 5-14 days. MDA say Btk is a biological product that is organic certified for food crops. It has no known health effects for humans, pets, birds, fish, livestock, bees, and other non-caterpillar insects.

To help area citizens stay informed, the MDA has set up an Arrest the Pest Info Line at 1-888-545-MOTH with the latest details about treatment dates and times. On the morning of the treatments, residents can call the phone number with any questions they may have. Simply press 0 (zero) to speak to someone. The MDA's website ( also has information about gypsy moths and control efforts. Residents can sign up for updates about treatment progress by texting “MDA DULUTH” to 468311 to receive text notifications or texting “MDA DULUTH [your email address here]” to 468311 to receive email notifications.

MDA says gypsy moth treatment must begin early in the morning for the treatment to work. Although the spraying has no known health effects, residents may want to stay indoors during the treatment and keep windows closed for a half hour after application.  Officials say soapy water will remove any residue on outdoor furniture and surfaces.
