Termites in India mostly live in the soil. They travel up into a building through tiny cracks in the floor, gaps along the walls and the space around pipes and wires. Anti-termite treatment works by placing a chemical barrier in the soil, so termites cannot reach the wood above. There are two ways to do this: before the building is constructed, or after it is already built.
What Is Pre-Construction Anti-Termite Treatment?
Pre-construction treatment is done while the building is being constructed. The soil is treated in stages, as the work progresses, so that the entire structure sits on a protected base:
- Foundation stage: the bottom and sides of the foundation trenches and pits are treated.
- Back-filling: the soil filled back around the foundation is treated.
- Plinth and floor level: the levelled soil is treated before the floor concrete is laid.
- Junction of walls and floor: the joints are treated where termites usually find a way in.
- Outside perimeter: after construction, the soil along the outer walls is treated.
Because the barrier is complete and nothing has to be drilled, pre-construction treatment gives the strongest and longest protection. The work follows the Indian Standard for anti-termite treatment of buildings (IS 6313).
What Is Post-Construction Anti-Termite Treatment?
Post-construction treatment is for buildings that are already built — when you see termites, or as protection for an older house. It is done with the drill-fill-seal method:
- Small holes are drilled at regular gaps along the joints of walls and floors on the ground floor.
- A government-approved termiticide is injected through the holes into the soil below.
- The holes are sealed neatly with white cement, so the floor looks the same.
- Wooden frames, doors and fixed furniture are treated separately where needed.
The treatment creates a barrier under and around the building. Termites already inside the wood die off because they cannot return to the soil for moisture.
Pre-Construction vs Post-Construction: Side by Side
| Pre-construction | Post-construction | |
|---|---|---|
| When it is done | During construction, in stages | Any time after the building is complete |
| Method | Soil treatment at each stage | Drill, fill and seal along wall–floor joints |
| Protection | Complete barrier under the whole building | Barrier along walls and floors; very effective when done properly |
| Typical warranty | 5 to 10 years | 1 to 5 years |
| Our price | ₹12 per sq ft | ₹10 per sq ft up to 1,100 sq ft, ₹7 per sq ft above |

What About an Anti-Termite Piping System?
A piping (pipe reticulation) system is laid under the floor of a new building. Perforated pipes run along the walls and connect to a small inlet outside. Whenever the treatment needs to be renewed, termiticide is pumped through the pipes — without drilling a single hole in your floor. It is a good choice for new homes, hotels and offices with expensive flooring. Our piping system costs ₹25 per sq ft. Read our full guide to the anti-termite piping system.
Which One Do You Need?
- Building a new house, hotel or office? Choose pre-construction treatment, and consider a piping system for easy refills later.
- Living in a house or flat that is already built? Choose post-construction treatment. If you have already seen termites, do not wait — the damage grows every month.
- Bought an old house or doing a renovation? Do a post-construction treatment before new woodwork and modular furniture are installed.
