Are you absolutely certain that they are powder post termites and not powder post beetles? To answer you question, no, it's not the best product for use in cabinets, it's designed for walls, studs, etc. The best product for cabinets would be Termidor SC or Termidor foam injected into the galleries. This won't work if it's powder post beetles.
If you are absolutely certain they are drywood termites, you could use Termidor Foam and inject it into the termite galleries. The bigger question is, are they termites or powder post beetles? What evidence are you seeing?
