I recently milled a black Walnut tree. It had termites, but only in the sap wood. The sawyer told me a trick he has used for years. B-12 carburetor cleaner. He claims it kills the termites & ants [you may want to make several applications over a period of time to be sure you kill any unhatched larva] and it will not stain the wood or effect any finish used on the wood. Of course, you would not want to try to finish the wood until all the B-12 had evaporated and dried out.

I cannot vouch for this claim. But i trust the person who told me about this.
