State sprays for gypsy moths

Any Cloquet residents awakened by the sound of a low-flying plane Wednesday morning can expect it to happen again within the next three to 12 days, according to the Minnesota Department of Agriculture.

The Wednesday morning flight was first of two aerial applications of a spray to help eradicate gypsy moth (now known as spongy moth) infestations detected in parts of Cloquet and Duluth last fall. The Cloquet site encompasses approximately 500 acres around the Sappi mill property, including the area near the St. Louis River and Cloquet Avenue The low-flying airplane travels up to a half mile outside these treatment areas as it navigates through the insect infestation sites.

The treatment product has no known health effects for humans, but residents may wish to stay indoors during the treatment and keep windows closed for a half hour after application. Residents can cover gardens or turn on sprinklers during the treatment if they wish.

The residue does not cause damage to outdoor surfaces. However, soapy water will remove any residue on outdoor items.

Gypsy moths are among America's most destructive tree pests, having caused millions of dollars in damage to Eastern forests. The moths spread slowly on their own, but people can unintentionally help them spread by transporting firewood or other items on which the moths have laid their eggs.

The MDA's website (www.mda.state.mn.us/gmtreatments) also has information about gypsy moths and control efforts. For updates, text “MDA MOTH” to 468311.
