FOR IMMEDIATE RELEASE: Friday, June 9, 2017

MDA to conduct final gypsy moth treatment north of Hinckley on Monday, June 12

Application is dependent on weather conditions

The Minnesota Department of Agriculture (MDA) is planning a final treatment north of Hinckley to a eradicate gypsy moth infestation detected last fall. Officials plan to conduct the treatments on Monday, June 12, starting as early as 5:30 a.m. This is dependent on weather conditions at the time.

In 2016, the MDA’s trapping program found an infestation north of Hinckley. To eradicate the moths before they spread, officials conduct two aerial applications of Bacillus thuringiensis var. kurstaki (Btk) over the same area. Two applications are needed because the product naturally breaks down in sunlight. The first application was conducted on Tuesday, June 6. (See map for application area.)

Btk is a U.S. Environmental Protection Agency-approved bacterium with very low risk for humans or animals other than caterpillars. Btk is widely used within the organic gardening community. Over the years, MDA has eradicated gypsy moth infestations on thousands of acres across the state using this method. These efforts protect forest health, property values, and the state's tourism industry.

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. If present in large numbers, gypsy moth caterpillars can defoliate large sections of forest.

To help area citizens stay informed, the MDA has set up an Arrest the Pest Info Line at 1-888-545-MOTH. The info line will offer the latest details about treatment dates and times. The MDA website (www.mda.state.mn.us/gypsymoth) also has information about gypsy moths and control efforts. Finally, the MDA offers the following tips to residents in the treatment area:

  • For the moth treatment to work, it must begin early in the morning. Monday’s treatment may begin as early as 5:30 a.m. Residents may be awakened on that day by the noise of the low-flying helicopter. MDA apologizes for any inconvenience;
  • The treatment product has no known health effects for humans, but to avoid it residents may wish to stay indoors during the treatment and keep windows closed for a half hour after application; and,
  • Any residue, which does not cause damage to outdoor items, can be removed soapy water.
