call the people that kiln dried the wood.
ask what temperature they used on your particular boards
and tell them about the bug evidence that you found – and see what they say.

I have noticed that “kiln dried” has so many specifications all over the country.
some heat the air to 140*f some don’t heat at all and only used big fans to
circulate the air and decrease the moisture content of the wood.

Like Arizona for example…... walk into a metal building there and you will DIE.

Kiln dried, I have learned, means different things to different people. There are certain requirements for kiln drying to kill bugs depending on thickness of the lumber. “Sterilization” as it is called, requires 140 degrees F for 3-5 hours, or 130 degrees F for 10-12 hours. This applies to lumber up to 8/4 thickness. Thicker lumber takes more heat and more time.

Once a load is sterilized it doesn’t stay bug free forever. It just kills the bugs that are present at the time. If stored indoors, in a climate controlled environment, it is likely fine.

I would check the moisture content at the core, just to make sure it was adequately kiln dried. Unless you live in Arizona, 10% or less M.C. and you’re fine.

I was told the wood was “cooked” at 130 degrees for 3-4 days per cycle (2X cycles). So it sounds like this should be enough to alleviate any concerns.

I had major problems with the little stinkers making powder of my gorgeous (and evidently very delectable) maple and claro walnut burls. Someone here on LJ suggested Tim-Bor which I used. It took 3 or 4 treatments because eggs were hatching, but they’re all done for. And it will literally shut down the cellular function of any bug that eats it. The manufacturer’s description was very scientific and technical, so it’s likely they know their stuff when it comes to bug elimination/prevention. Not dangerous to people as far as I know :-P. Just wish I could get my burls back lol.
Amazon sells it. Best wishes!
