All firewood of out-of-state origin is prohibited from the State of New Hampshire unless it is labeled as certified heat-treated to 140°F (60°C) for 60 minutes. Untreated out-of-state firewood may only be moved into New Hampshire under compliance agreement and to a certified heat-treatment kiln or similar facility that will mitigate the pest risk associated with the transportation and storage of the firewood. Firewood originating in New Hampshire but transported out-of-state for processing may be eligible for a compliance agreement to move the material back into New Hampshire if origin can be documented, and identity and security of New Hampshire-origin firewood is maintained in the processing yard.
Within New Hampshire:
All firewood (48” or less, split or unsplit) of any hardwood species or any ash (Fraxinus) material cannot be moved from Belknap, Hillsborough, Merrimack, Rockingham or Strafford counties (complete list of towns). Processors of wood (firewood kilns, mills, chippers, etc.) may qualify for a compliance agreement with the state of New Hampshire or the USDA APHIS PPQ.
Maine, Vermont, Massachusetts, Connecticut, New York, and many other states also have restrictions on moving firewood. Federal restrictions may apply depending on origin of firewood. For more information, visit www.dontmovefirewood.org.
Don't move firewood from the New Hampshire towns pictured within the purple boundary to towns within the New Hampshire counties in gray (see the full list of towns by county here).

- When you buy firewood locally, get a receipt.

- Tell your friends about the risks of traveling with firewood– no one wants to be responsible for starting a new pest infestation.
