I do woodwork and have some lumber with powder post beetle infestation. I have used some off the shelf / Ortho ant and termite treatment that was effective but after a few years they are back. My shed is against the woods and the West Virginia DNR indicated there is no real escape. I do not doubt the effectiveness of Boracare but how safe is it to humans? I just built a poplar tack box for a grandchild and saturated it with mineral spirits after heating the wood to about 150 degrees or more. When that is dried, I planned to finish and seal with polyurethane.
