Thanks for answering. The land is in INDIA.Its in North india 200 kilometers from delhi(CAPITAL OF INDIA).its a small town (Ambala city). The sand is mix land like in riverbed

My research shows multiple species of termites in that area. Here is a link to an article about a practical expert much closer to you and more familiar with the different types of termites and treatment methods available there. You should perhaps contact him.

I just wish we could still get Chlorpyrofos (Dursban) in the U.S. That stuff really worked good on roaches and ants.
