It is against the law to bring out-of-state firewood into Colorado from areas infested with regulated forest pests like imported fire ant, spongy moth, spotted lanternfly, and Asian longhorned beetle. To protect Colorado’s urban and native trees from harmful invasive pests, the Colorado Firewood Task Force recommends people use firewood originating from Colorado whenever possible. Colorado state authorities provide the following additional recommendations for firewood users to help prevent the spread of damaging forest pests:

Additionally, firewood should not be taken out of Colorado to prevent the further spread of harmful forest pests and diseases like emerald ash borer and thousand cankers disease of walnut.

Parks and campgrounds often have their own firewood rules. For example, Rocky Mountain National Park asks that visitors purchase firewood in or near the park to avoid introducing harmful insects; firewood is available at all campgrounds during the summer season. Call ahead to find out the firewood rules at your destination before traveling with firewood.
