How does Termidor SC kill Drywood Termites?

After reading all I can on your site and others, about both Subterranean and Drywood termites, it seems apparent that the treament methods are different. How is Termidor used to treat for drywood termites? Also, which of these termites is more likely to emerge from ceilings?


Drywood termites are all contained in a piece of wood.  They do not go back to the ground like subterranean termites.  For Termidor to work on Drywood termites, you have to drill directly into the piece of wood the termites are in and inject Termidor into the wood.  Termidor does not penetrate into wood, so you have to inject it into the center.  It has to touch the termites to work, but the benefit is that it only has to contact a few termites, and then they can pass it on to the rest of the colony.  Either drywoods or subterranean termites can emerge from a ceiling, but only drywood termites kick out little sand like, hard, droppings.  Subterranean termites do not.
