You can treat with boric acid (timbor or boracare) but if any pest control businesses in your area do fumigation (tenting) for drywood termites and have a vault, they can gas it for you with no residue and immediate results. If tenting is common in your area, call around and ask who has a vault for furniture. You may be too far from the Gulf for drywoods to be common.

Applying a borate solution will not kill the eggs or the larvae that are already in the wood. It is a surface treatment. Heat is the best treatment once the wood is infested. That will likely require a kiln. The internal wood temp has to reach 140 – 150 degrees for 4 or 5 hours. Internal wood temp, not surface temp.

You might check your supplier if you can; if the wood has been kiln treated then the wood will be just fine. Kiln treated, not simply dried. Treatment needs to get the wood to 133 degrees f thru and thru. If it has been treated, then it will be ok. If not, you may need to. Liquid solutions require the wood to be wet to work; they mix with the current moisture in a wood and can reach the center of said wood and all bugs and larvea are done for. They do not necessarilly work on dry wood, as there isn’t necessarilly enough moisture to carry the liquid you try to use. If you can’t do any of this, then use it anyway and watch for little piles of sawdust (frass) that accumulates on or at the base of the wood when it gets good and warm. They can survive a few years as eggs under premium conditions.

I reclaimed and entire barn last year, and was concerned about PPB’s, but I wonder if these things sometimes move on or what. It’s the second time I’ve been around “supposably” untreated wood that had PPB holes, but no beetle or larvae. I’ve cut, planed and jointed enough of it by this time to have found them if they were there.

Then again, may it wasn’t PPB’s…
