Dear Don't Move Firewood,
I live in Missouri and I camp often. Is it ok to use lumber without bark?
Dear Concerned Camper,
What a deceptively complicated question- and a good one to ask. Lumber (I assume you mean cut firewood, not construction lumber here) without bark is indeed a bit less likely to contain bark dwelling insects, or insects that burrow between the bark and the heartwood (like emerald ash borer). But it is NOT safe 100%, and thus it often violates state or federal quarantines regardless of what part of the tree that an insect might prefer. Firewood without bark is not OK to transport from a practical, and often legal, perspective.
I found this nice brochure on the specifics of emerald ash borer in Missouri. From there, you can learn about one pest in Missouri- but there are others, like thousand cankers disease, that also spread on firewood (and in the heartwood, so de-barking doesn't help at all) and are also a big threat.
Verdict? Not a good idea. Please either keep firewood local, or buy it near your destination. Thanks for asking.
