The simple answer to your question is, do you know where the drywood termites are located? If so, then yes the treatment is fairly straightforward. If you do not know where they are located, then you are up for a challenge. Here is a repost from on a question on this topic -
Depending on where the drywood termites are located, a spot treatment with Termidor Foam can eliminate them in specific areas. Simply locate the "kickout" holes where the drywood termites are dumping their "frass" or wood pellets from and drill a small hole into this kickout hole. Drilling through the kickout hole will hopefully lead directly to the chambers inside of the wood in which they are eating nesting.
Drilling the entire wall and foaming the entire wall in a checkboard fashion with holes every 12 " or so may also be necessary. If the termites are on an outside wall, and there is paneling or wood sheathing, drilling the same way, also drilling eaves, window boxes, etc, is recommended. The bottom line, drywood termites can be anywhere, and you have to drill as many holes as possible to get as much Termidor Foam as possible inside the walls. This could take 1 can of foam, it could take an entire case or more.
Any aerosol product such as D Foam, Invader, Premise Foam, etc, will work, but I recommend Termidor Foam.
Another option is to get Termidor SC and mix it into a Solo Wall Foamer. This is much more economical than using a case of foam. Its great for foaming an entire home, many walls. You will need the Solo Wall Foamer, Termidor SC and Foaming Agent such as Pro Foam Platinum. Mix the Termidor SC and Pro Foam with water into the sprayer and walla! Instant thick foam.

Fumigation with Vikane is usually the recommended treatment for Drywood termites, as my recommendations are for spot treatment only. However, if you do this right, and kill the drywood termite colonies, you can reduce and maybe eliminate the need for fumigation. Many of our customers have done this with great success. If I had drywood termites in my home, I would certainly do everything possible to avoid fumigation. And if I had to do it, only as a last resort after I had exhausted all other options.
