Post-Construction Termite Treatment: What Hyderabad Flat Owners Should Know

If you have found mud tubes on a wall, hollow-sounding door frames or a swarm of winged insects after the first rains, you are probably looking into termite treatment for your flat in Hyderabad. The usual answer for a building that is already lived in is a post-construction treatment. This guide explains how it works, who in your society may need to agree to it, how to prepare your home and what paperwork to keep afterwards.

It is written for owners and tenants of flats, independent houses and villas in gated communities. If your building is still under construction, the approach is different; see our guide to pre-construction anti-termite treatment for builders.

How do you know it is termites?

Subterranean termites live in the soil and travel into buildings looking for cellulose: wood, paper, cardboard and even the backing of some boards. Because they avoid light and dry air, they move inside wood or through mud tubes they build along walls, beams and pipes.

Common signs include:

• Pencil-thin mud tubes on walls, skirting, the back of cupboards or along plumbing and electrical lines
• Door frames, skirting or wardrobe panels that sound hollow or crumble when pressed
• Small heaps of discarded wings near windows or lights, often after the first monsoon showers
• Soil-like material packed into cracks or the joints of wooden frames

Fine powder and small round holes in furniture usually point to wood borer rather than termites. Our guide on how to tell termites from wood borer explains the difference, which matters because the treatments are not the same.

How does drill–fill–seal treatment work?

The Indian Standard IS 6313 Part 3 deals with anti-termite treatment of existing buildings. In general terms, the aim is to put a continuous chemical barrier between the soil, where the colony lives, and the timber and other materials inside your home. In an occupied building this is done through the floor and walls rather than by digging up the ground. The steps below describe common practice in general terms.

1. Inspection. A technician checks every room, wardrobe, kitchen cabinet and service duct to find where termites are active and how they are entering. This decides where drilling is needed.
2. Drilling. Small holes are drilled along the junction of the floor and walls, around door frames, at expansion joints and near points where pipes or conduits enter. The exact spacing and positions depend on the building and on what the inspection finds.
3. Filling. A diluted termiticide, which should be registered with the CIB&RC under the Insecticides Act, 1968, is injected into the holes under pressure so it spreads into the soil or fill beneath the floor.
4. Sealing. The holes are closed with cement or a filler matched as closely as practical to your flooring.
5. Woodwork treatment. Affected door frames, wardrobes and other timber are treated by injection or surface application. Wood that is badly damaged may need a carpenter to replace it.

Where the ground around an independent house or villa is accessible, the outer perimeter may also be treated so termites cannot approach the walls from outside.

What about flats on upper floors?

Termites in an upper-floor flat usually come up from the ground through cracks, expansion joints, service shafts and conduits. Treating your flat will deal with termites inside it and protect your woodwork, but it may not reach the source. If several flats are affected, a building-level treatment at ground level and in common shafts, arranged by the society, is often the more lasting approach.

Do you need society permission?

Often, yes. Even when the work is entirely inside your flat, drilling is noisy and some steps may touch shared parts of the building. It is easier to sort this out before a date is fixed.

If termites are showing up in more than one flat, raise it at the committee level. A coordinated treatment is usually more effective than each owner acting separately.

How should you prepare your home?

Good preparation makes the treatment quicker and more thorough. Our detailed checklist for termite drilling preparation covers this step by step, but the essentials are:

• Move furniture, beds and heavy items a little away from the walls so floor–wall junctions can be reached
• Empty lower kitchen cabinets, wardrobes and shoe racks where termites are active
• Pack away food, utensils, clothes and children's toys, or cover them well
• Share any drawings of concealed pipes, wiring or underfloor heating so drilling avoids them
• Tell the technician about marble, granite, wooden or other special flooring before drilling starts
• Plan for children, elderly family members and pets to be away from treated rooms until surfaces are dry, or as the technician advises

After treatment, ventilate the rooms, follow the advice given on when to return and clean, and wash hands after touching treated areas. Avoid mopping along sealed holes and wall edges until you are told it is fine. If anyone feels unwell after a treatment, see a doctor and take the product details with you.

Why not treat termites yourself?

Spraying visible termites or mud tubes kills a few workers but leaves the colony in the soil untouched, and they simply find another route. A proper barrier needs the right equipment, a correctly prepared and registered product, and knowledge of how your building is constructed. Treatments should be carried out by a pest control operator licensed under the state's procedures, who uses products as the label directs.

What follow-up and records should you expect?

Termite treatment is not finished on the day of drilling. A follow-up inspection checks that activity has stopped and that no new entry points have appeared. How long protection lasts depends on the product, the soil and later disturbances such as renovation; our article on how long anti-termite treatment lasts explains the factors.

Ask for, and keep, the following:

• A written inspection report showing where termites were found
• A record of the areas and rooms treated, and the date
• The name of the product used and its registration details
• The Material Safety Data Sheet (MSDS) on request
• Warranty terms in writing, including what is excluded
• Dates of follow-up inspections

These records help if termites return, if you renovate, and when you sell or rent out the property. A buyer may want to know about past treatment, as our guide on termite inspection before buying a flat in Hyderabad explains.

How we approach termite work

Across the company, we follow an Integrated Pest Management approach: inspect first, give sanitation and proofing advice, then treat in a targeted way. We maintain Material Safety Data Sheets for the products we use. At our established Goa operation, clients receive service reports after visits along with WhatsApp updates.
