Saving beetle-damaged reclaimed framing lumber
Is there a practical way to make safe beetle damaged framing lumber?
In this case it’s 1930’s era old growth douglas fir 2×4 rafters, which were removed then stored outdoors. Pretty much all of them have beetle exit (or entry) holes (see representative picture). The wood is plenty strong, but clearly the beetles can (and did) spread.
In theory killing methods include: heat/kiln cooking, chemical saturation, microwave energy like that used for termites, freezing. But in practice, in the San Francisco Bay Area, is this wood compost or fixable? What’s the green thing to do?
