On Tuesday, June 19, The Minnesota Department of Agriculture (MDA) is planning a second treatment to eradicate gypsy moth infestations in areas in Cloquet, Duluth, Two Harbors, and White Iron Lake near Ely. This is dependent on the weather at the time.

The aerial treatments will start as early as 5:15 a.m. in Duluth, followed by White Iron Lake near Ely, Two Harbors, and Cloquet, which will be completed around noon. If weather conditions are not favorable the entire time, any remaining areas will be treated the next day, Wednesday, June 20, starting as early as 5:15 a.m.

The low-flying airplane will be traveling up to a half mile outside the treatment areas as it navigates through the gypsy moth infestation sites. The MDA apologizes for any inconvenience caused by the noise of the plane.

The treatment product, Bacillus thuringiensis var. kurstaki (Btk), is a biological product that is organic certified for food crops. It has no known health effects for humans, pets, birds, fish, livestock, and bees. However, you can avoid it by staying indoors during the treatment and keeping windows closed until a half hour after application. Any residue, which does not cause damage to outdoor items, can be removed with soapy water.

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, you can call the phone number with any questions you may have. Simply press 0 (zero) to speak to someone. The MDA's website (www.mda.state.mn.us/gmtreatments) also has information about gypsy moths and control efforts, and residents can sign up for email or text updates about treatment progress.

Details of treatment areas:

  • Cloquet: A 460 acre area that runs north of MN Highway 45 up to Pearl and State streets.
  • Duluth: A 352 area in the Lakeside Neighborhood that begins approximately at Oneida Street on the south and North 52nd Avenue East on the east and extends northwest past Skyline Drive.
