Might that possibly be Termidor? This is a Restricted Use Pesticide and can only be sold to a licensed pesticide applicator. The best thing to do is find a good, competent pest control person to do the work for you. Seldom is anything you can buy and apply effective at controlling termites in your house.

The other thing is that termite queens fly, and colonies burrow in tubes of mud into the house. Spraying would not defeat either one. Better to find someone that knows what they are doing and has insurance incase something goes wrong. Baits that the termites take back to the nest are more effective in killing the whole thing rather than just a passing insect.
