The Minnesota Department of Agriculture (MDA) and partner organizations are planning to tackle a gypsy moth infestation in part of the city of Cloquet this spring. In anticipation of the proposed treatment, the department is inviting people to learn about the effort at an open house on April 12 in Cloquet.

Gypsy moths are ranked among America’s most destructive tree pests. The insect has caused millions of dollars in damage to forests as it has spread from New England to Wisconsin in recent decades. Gypsy moth caterpillars can defoliate large sections of forest. The pests are common in Wisconsin and are now establishing themselves in Minnesota.

The MDA maintains a monitoring program to watch for start-up infestations, and when an infestation is found, the department conducts aerial treatments of the infestation before it can spread. In 2017, the MDA found a gypsy moth infestation in Cloquet. The department is now developing a treatment plan for an affected 460 acre area that runs north of MN Highway 45 up to Pearl and State streets (SEE MAP). Details of the area can be found at

The MDA will host the open house from 5:30 – 6:30 p.m. on April 12 to share information with citizens about the threat gypsy moths pose to the environment and how officials plan to protect the urban and natural forest.

Meeting details:
Thursday, April 12, 2018
5:30 – 6:30 p.m.
City Hall, Council Chambers
1307 Cloquet Ave.
Cloquet, MN 55702

Over the years, the MDA has successfully treated dozens of gypsy moth infestations across eastern Minnesota from Grand Portage to the Twin Cities to Houston County, including treatments in Cloquet in 2012. These successful treatments help postpone the full-scale invasion of gypsy moth, saving local communities and homeowners money and protecting the health of the state’s urban and natural forests.
