Harmful pests like emerald ash borer, Asian longhorned beetle, spotted lanternfly, and the red imported fire ant have the potential to cause irreversible damage in Washington. These pests can spread to new areas via the movement of firewood. As a result, the Washington Invasive Species Council encourages the public to use firewood from local sources with their campaign, “Buy it where you burn it”, and make the following recommendations:

  • Call ahead to your camping destination to find a local wood dealer
  • Never travel with firewood–always buy it near where you will burn it
  • Burn all your firewood before leaving your campsite

Additionally, moving firewood into Washington (WA) from many eastern states is against federal law to prevent the spread of gypsy moth (see the federal quarantine map). Similarly, firewood should not be brought into WA from any area with a detected infestation of emerald ash borer. Further, many outside states prohibit the entry of firewood coming from WA due to the risk of spreading thousand cankers disease of walnut.

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.
