Do you know what species of termites you have? Subterranean or drywood? What are you seeing, mud tunneling or dry wood pellets?

The thing to remember about subterranean termites, is that they always come from the soil. They live in colonies underground and below the home, not always inside the walls or the ceiling.
Typically, for subterranean termites treating any area is considered a "spot treatment" and depending on which chemical you use, it could very well drive the termites to other non treated areas. Be sure to use a non-repellent chemical such as Termidor, Taurus, Premise or Optigard Flex for subterranean termites.
I would recommend to at least treat the outer perimeter with Termidor SC (trench and treat) and then find the area where the termites are getting in. This is usually around plumbing lines or cracks in the slab. You can use Termidor foam to inject the walls around these areas.
Foaming the ceiling where the termites are located probably will do very little to stop them. If you look straight down the ceiling, and then down to the floor level, you will probably find the source of their entry. Treating these wall voids with Termidor foam at the base of the wall, saturating all of the wood around these entry points, etc, will go a long way towards eliminating them.
