Powder post beetles "larvae" will chew their way through the wood, riddling it with galleries. But they are not the same as a gallery in which Drywood Termites would make. While you can drill into the wood and into the gallery that Drywood Termites would make, doing this for Powder Post Beetles would be very difficult. The reason is that each PP Beetle larvae would make its own gallery. You would have to find each gallery and drill into it. If you have a hundred or so PP Beetle Larvae in a section of wood, drilling all of these holes would be difficult to say the least.
The best method for PP Beetles is to treat the entire section of wood with either Bora Care or Totality. This may not be possible if the wood is stained for finished, as these products are only designed to treat bare wood.
Fumigation of the wood may be the only other option, which would have to be performed by a licensed fumigator.
Hope this helps.
