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:
- Use local firewood for both camping and home heating
- When harvesting, make sure to cut, debark, and dry the firewood
- Buy firewood at or near the campground
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.

(Note: Open fires are not allowed at most of Colorado’s National Wildlife Refuges. National Parks, Forests, and preserves often have fire restrictions when wildfire risk is high. Visit the website of your destination or ask campground staff for the most current information.)
