    • This website provides information about the gypsy moth and Minnesota's efforts to monitor this invasive species.

      The gypsy moth is one of North America's most destructive tree pests. In eastern states with significant infestations, gypsy moth caterpillars have defoliated entire forests and caused millions of dollars of damage to urban landscapes. In North American the gypsy moth range extends from the Canadian Maritime provinces, south to North Carolina, and west to Wisconsin and Minnesota.

      The Minnesota Department of Agriculture (MDA) tracks gypsy moth movement into our state. Annually, gypsy moth populations are monitored through a summer trapping program. The goal of this summer monitoring program is to determine the extent of gypsy moth populations in Minnesota and to detect areas with high moth concentrations.

      When areas with high gypsy moth concentrations are found, standard treatment protocols are applied to reduce localized infestations to protect our forests, local property values, and our state's vital tourism industry.

      Annually, the federal government cooperates with states to update regulations that are implemented to limit the spread of gypsy moth pest populations. Regulatory decisions are based on data collected from the trapping program.

      It is illegal to knowingly transport any life stage of the gypsy moth out of a quarantined area. Individuals visiting quarantine areas can help prevent moving gypsy moths by conducting a self-inspection of outdoor items. What you need to know when visiting a gypsy moth quarantined area.

      Businesses that regularly move high-risk materials from quarantine areas can apply for a compliance agreement with the MDA and the U.S. Department of Agriculture. This agreement specifies terms of movement to minimize the risk of introducing gypsy moths to uninfested areas.

    • The Minnesota Department of Agriculture (MDA), in collaboration with federal, state, and local partners, has proposed to slow the spread of gypsy moth populations in Carleton, Hennepin, Lake, and St. Louis counties. Surveys in 2017 revealed six distinct areas where monitoring traps caught a high numbers of moths. These results, combined with the trap records of previous years and follow-up site surveys, prompted the MDA and the Minnesota Gypsy Moth Program Advisory Committee to develop a proposed treatment project for 2018.

      Public involvement and participation is encouraged. Citizens are invited to submit comments about the gypsy moth treatment proposal in writing to the MDA. All comments will be reviewed and a response will be given. Comments received by March 15 will be most useful for identifying issues and alternatives for the required environmental assessment. Site specific environmental assessments will be prepared to identify and consider local issues before the project is authorized by the federal government and implemented by the state. A final environmental assessment is expected to be released in April. It will be posted on this website and on participating agency websites.

      Comments can be submitted in writing to the MDA at 625 Robert St. N, St. Paul, MN 55155, or by emailing gypsy.moth@state.mn.us.

    • A delta orange gypsy moth trap

      Each year the MDA sets around 20,000 gypsy moth traps throughout Minnesota to determine the location and size of gypsy moth populations.

      The gypsy moth trapping survey program concentrates on the eastern half of the state due to the natural westward movement of gypsy moth through Wisconsin as the population front expands. Selected high-risk businesses also receive survey traps throughout the annually designated trapping survey project area.

      Please visit the trapping survey page for more detailed information.

    • The MDA recommends using the License Information Search to begin your search for companies on the Tree Care Registry. All Tree Care Providers including companies and persons that provide tree care or tree trimming services and/or who remove trees, limbs, branches, brush or shrubs for hire in Minnesota are required by state statute to register with the MDA. If you cannot find a provider on this list they are not registered as a Tree Care Service in Minnesota.

      In addition to checking the Tree Care Registry, there are additional steps you can take to ensure that a service provider is properly licensed and insured. See this checklist for assistance when hiring a tree care company.
