Termites are one of the most silent yet destructive pests that attack buildings. They slowly damage wooden doors, windows, furniture, and even weaken the structure by hollowing it from inside. Once termites spread in a building, it becomes very difficult and costly to remove them. That is why Anti-termite treatment has become an essential step during construction. It is a preventive measure that protects the structure from future termite attack and increases the life of the building.
In this blog, we will explain what anti-termite treatment is, the different procedures used in construction, and the advantages of this method.
What is Anti-termite Treatment?
Anti-termite treatment is a process where soil, foundations, and building components are treated with chemicals to create a protective barrier against termites. The idea is to stop termites from entering the building through the soil or cracks. This treatment is carried out before, during, or even after construction depending on the stage of the building.
Why Anti-termite Treatment is Important in Construction
- Protects structure from damage: Termites feed on cellulose present in wood and paper. They can damage doors, window frames, cupboards, and false ceilings.
- Prevents costly repairs: Once termites spread, controlling them becomes very expensive. Preventive treatment at the time of construction saves future costs.
- Increases building life: Treated soil and wood remain protected for years, ensuring the strength and safety of the structure.
- Gives peace of mind: Homeowners and builders remain stress-free as the chance of termite attack becomes very low.
Pre-construction Anti-termite Treatment
This method is carried out during the building stage and is considered the most effective. Since the foundation and flooring are not yet completed, chemicals can be applied at all critical points.
Steps in Pre-construction Treatment:
- Soil excavation treatment – Spraying chemical solution on excavated trenches and pits before foundation work.
- Foundation wall treatment – Applying chemicals around foundation walls and in plinth filling.
- Floor treatment – Treating the soil beneath the flooring before concreting.
- Wall and floor junctions – Blocking common entry points by applying chemicals at wall-floor junctions.
- Service pipe entry points – Sealing around pipes, ducts, and drains with anti-termite solution.
- Perimeter soil treatment – Spraying the external soil around the building after construction.
Post-construction Anti-termite Treatment
This method is done in already-built structures where termites have been spotted. It is more complex as access is limited.
Steps in Post-construction Treatment:
- Inspection – Professionals check walls, floors, and furniture to trace termite colonies.
- Drilling holes – Small holes are drilled at the base of walls, floors, and near junctions.
- Chemical injection – Termiticide is injected under pressure into the holes.
- Sealing – Holes are sealed with mortar after injection.
- Soil treatment outside – External perimeter soil is treated to block fresh entry.
Eco-friendly Anti-termite Alternatives
For those who prefer green methods, these options can be considered:
- Neem oil or extracts – Natural repellents for wood.
- Orange oil treatments – Effective against dry wood termites.
- Physical barriers – Using stainless steel mesh or sand barriers under flooring.
- Termite-resistant wood – Pre-treated timber for furniture and door frames.
Stages of Anti-termite Treatment in Construction
The treatment is normally done in stages during building construction. Each stage ensures proper protection against termite entry.
1. Soil Treatment Before Foundation
- The soil below the foundation is treated with chemical solution.
- This step prevents termites from moving up from the ground into the foundation.
- Chemicals are sprayed on excavated trenches and pits before laying concrete.
2. Treatment of Foundation Walls and Plinth Filling
- Once the foundation walls are built, the soil around them is treated.
- The refilled soil in contact with foundation is sprayed with anti-termite chemicals.
- This creates a continuous barrier around the structure.
3. Treatment Below Flooring
- Before flooring is laid, the soil below the floor is treated.
- It ensures termites cannot enter the building through cracks or gaps in the flooring.
4. Treatment of Junctions of Walls and Floors
- Junctions are weak spots where termites often find entry.
- Chemical treatment is done at these points to block termite paths.
5. Treatment Around Pipes and Conduits
- Termites often enter through pipe openings and conduits.
- Chemicals are applied around service pipes, floor drains, and ducts to seal the gaps.
6. External Perimeter Treatment
- After construction, the external soil around the building is treated.
- It forms a protective outer shield against termite attack from surrounding areas.
Chemicals Used in Anti-termite Treatment
Some commonly used chemicals in anti-termite treatment include:
- Chlorpyrifos (1% solution)
- Imidacloprid (0.05% solution)
- Fipronil (0.1% solution)
- Bifenthrin
These are mixed with water and applied in recommended dosages. Care must be taken to follow safety precautions while handling chemicals.
Methods of Anti-termite Treatment
- Pre-construction treatment – Carried out at the time of building construction. It is the most effective method as soil can be treated at all critical points before flooring and foundation work.
- Post-construction treatment – Done in existing buildings where termite infestation is already seen. Holes are drilled in floors and walls, and chemicals are injected to create barriers.
Advantages of Anti-termite Treatment
- Provides long-term protection against termites.
- Reduces maintenance and repair costs.
- Safe for wooden furniture and fittings inside the building.
- Protects not just wood, but also books, clothes, and electrical wiring.
- Increases resale value of property as buyers trust termite-protected homes.
Professional vs DIY Anti-termite Treatment
DIY methods like spraying kerosene, salt water, or vinegar give only temporary relief.
Professional services use certified chemicals and ensure proper soil injection.
For long-term results, always hire licensed pest control professionals.
Safety Measures During Treatment
- Always use protective gear like gloves and masks when handling chemicals.
- Chemicals must be applied in the right dosage to avoid health hazards.
- The treated area should be left undisturbed until it dries completely.
- Only trained professionals should be hired for the job to ensure proper application.
IS Codes for Anti-termite Treatment
In India, the Bureau of Indian Standards (BIS) has laid down codes that guide the proper procedure for termite control in buildings:
IS 6313 (Part 1): 1981 – Guidelines for Pre-constructional Chemical Treatment.
IS 6313 (Part 2): 1981 – Guidelines for Post-constructional Chemical Treatment.
IS 6313 (Part 3): 1981 – Protection of Buildings by Using Chemicals.
Conclusion🎯
Anti-termite treatment is not just a protective measure but an investment in the long life of your building. It saves future repair costs, keeps the structure safe, and protects furniture, books, and valuables from termite attack. Whether during construction or after, carrying out proper treatment ensures that termites never find a way into your home.
FAQs on Anti-termite Treatment
Q1. When is the best time to do anti-termite treatment?
The best time is during construction (pre-construction stage). However, it can also be done later as post-construction treatment.
Q2. How long does anti-termite treatment last?
Pre-construction treatment can last for 8–10 years if done properly. After that, re-treatment may be required.
Q3. Is anti-termite treatment safe for humans?
Yes, if carried out by professionals with recommended chemicals and safety precautions, it is safe.
Q4. Can I do anti-termite treatment myself?
It is not advised as handling chemicals requires skill. Professional pest control experts should be hired.
Q5. Does anti-termite treatment affect pets?
Pets should be kept away until the treated area dries completely to avoid health risk.
