Air drying maple and powder post beetles

[chet]

How low can I get the moisture content of maple while air drying before powder post beetles become a concern? I'd like to air dry first to speed up my solar kiln turn around time.

Under 20% would see a higher risk, but remember that you still need a source of infection.
