Could there be visible Powderpost Beetle powder after treating with BoraCare and staining?
After treating raw poplar wood board and batt siding on my house twice with 1 to 1 ratio BoraCare then staining with an oil base stain, I have active Powderpost Beetle exit holes in the wood. Is it possible for beetles to exit and the wood still be treated for future infestations?
Yes, the wood that you have treated with BoraCare is still treated for future infestations. The larvae that were present in the holes when you treated, still have to hatch and consume the wood for it to eradicate the population. The exit holes and powder you are experiencing are those new hatchlings of Powderpost Beetles. According to the BoraCare label when treating for Powderpost Beetles, watiing 6 weeks is recommended before staining or painting the wood to give any unhatched larvae time to exit.
