It is illegal to bring untreated firewood into Michigan from areas quarantined for Asian longhorned beetle, thousand cankers disease, basalm woolly adelgid, hemlock woolly adelgid, mountain pine beetle, and/or imported fire ant. In many cases, it is also against federal law to move firewood out of Michigan due to a spongy 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.

Many National parks, state parks, and private campgrounds in Michigan prohibit outside firewood unless it has been certified, heat-treated. 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.
