It is illegal to bring untreated firewood into Michigan from areas quarantined for Asian longhorned beetle, thousand cankers disease, basalm woolly adelgid, imported fire ant and/or spotted lanternfly. In many cases, it is also against federal law to move firewood out of Michigan due to a gypsy moth infestation in the state. To prevent the spread of these and other invasive forest pests, Michigan authorities ask residents and visitors to adhere to the following state-issued guidelines when using firewood:

  • Buy firewood where you will burn it, ideally within 10 miles.
  • Use firewood that is certified, heat-treated.
  • Leave your firewood at home when going camping; buy it at your destination or collect dead and down wood onsite when permitted.
  • Burn all your firewood, do not take any home with you.
  • Find local firewood vendors in Michigan by visiting Firewood Scout.

National parks, state parks, and many private campgrounds in Michigan prohibit outside firewood. Please remember to learn the firewood rules at your destination before visiting.

Bringing firewood from Canada into the USA is prohibited unless the firewood is labeled and certified heat-treated. Read about these requirements on the USDA and CBP firewood information sheet.

Bringing firewood from the USA into Canada is prohibited unless the firewood is labeled and certified heat-treated. Canada also encourages visitors to use local firewood.

This summary is accurate to the best of DMF staff abilities as of 16 July 2021.

Update: Michigan Department of Agriculture and Rural Development has proposed a state-wide exterior firewood quarantine which would require firewood entering the state to be certified as heat-treated at a temperature of 140 degrees F. (60 degrees C.) for at least 60 minutes.
