I had trouble with PPB in some butternut stored in a shed loft and used Timbor (similar to Boracare). I sprayed both sides of each board and restocked them with stickers. The Timbor does not penetrate deeply and does not kill the eggs. Whens the larva emerge, the residue kills them. I also sprayed the other boards in the loft. It worked.
