Idaho prohibits the transport of invasive species into or through the state, which means bringing firewood infested with any invasive species into Idaho is against the law. Since it is incredibly difficult to tell if firewood is contaminated with invasive insects or pathogens, it should not be brought into the state unless it is certified, heat-treated to kill pests like emerald ash borer, Asian longhorned beetle, spotted lanternfly, and spongy moth. To prevent these and other invasive tree pests from entering the state, authorities in Idaho encourage residents and visitors to buy local firewood within the state. Also, moving firewood from Idaho into most midwestern and eastern states is against state laws, as this can spread forest pests like thousand cankers disease of walnut.
The state of Idaho supports the following recommendations for firewood users:
- Buy it where you burn it, both for camping and home heating
- Make sure your firewood comes from within 50 miles, and ideally within 10 miles of where it was cut
- When going camping, buy firewood at or near the campsite
- Leave any remaining local firewood at the campsite or leave it with the camp host
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.
