Emerald Ash Borer Quarantine and Regulatory Information


The emerald ash borer (EAB) is a serious invasive tree pest, and consequently a quarantine has been placed on Dakota, Hennepin, Houston, Olmsted, Ramsey, and Winona Counties to help slow the spread of EAB to other areas (map). Materials such as:

  • ash logs and lumber
  • ash tree waste
  • ash chips and mulch
  • all hardwood firewood;

are now considered regulated articles by the Minnesota Department of Agriculture (MDA).

No regulated articles are legally allowed to move outside of a quarantine (untreated or treated), except if it is done so under the terms of a Compliance Agreement with the Minnesota Department of Agriculture and/or the United States Department of Agriculture.

A Compliance Agreement is a written agreement between an entity and a regulatory agency (MDA and/or USDA) to achieve compliance with regulatory requirements. For more information about Compliance Agreements please visit our Frequently Asked Questions (FAQ) or contact the Arrest the Pest Hotline.

Please refer to the official state quarantine for the full list of regulated articles and other important information regarding movement of regulated articles.

The EAB quarantine in Minnesota is part of a much broader quarantine effort by USDA enacted to slow the spread of EAB to states not currently infested with EAB (map).
