In this article, we explained full procedure of anti termite treatment in building, pre treatment, and post treatment. chemicals used for anti termite treatment
What is Anti termite treatment?
The treatment done to prevent the growth of termites in the house is called anti-termite treatment.
There are two types of termites.
- Dry wood termite
- Sub-terranean termite
1. Dry wood termite
Dry wood termite lives in wood and eats wood hollow. It has nothing to do with clay.
2. Subterranean termite
Subterranean termite live in the ground and eat wood, leather, paper, etc.
Methods of Anti Termite treatments
Anti termite treatment can be divided into two parts.
- Pre-construction Anti Termite treatment
- Post-construction Anti Termite treatment
1. Pre-construction Anti Termite treatment:
This treatment is done in two stages.
- Site Preparation
- Soil treatment
1. Site Preparation:
Wood pieces, tree roots etc. are removed from the place where construction is to be done. If a termite infection is found, it should be treated with chemical drugs. A hole is drilled in the raft and a disinfectant solution is poured into the hole.

2. Soil treatment:
In these phases the soil below and around the building is treated with a solution of disinfectant chemicals, the chemicals used for anti termite treatment are as follows:
Soil treatment is given in the following stages.
1. Excavation for Foundation trenches, column pits, basement:
The bottom surface and vertical surfaces of excavation up to a height of 300 mm, should be treated using 5 liters of solution for 1 m2 area.
The soil filling in the foundation work, columns, basements etc. should be treated using 7.5 liters of solution for 1 m2 of vertical surface area.
2. Soil used in plinth filing:
The topmost layer of soil used for filing in plinth needs to be treated with suitable chemical solution.
It has a 50 to 75 mm deep, 150 mm c/c hole in the soil filling between the four walls. The solution is poured into it at the rate of 5 liters per square meter area.
3. Near the junction of walls and floor:
In this way, a 30 mm wide and 30 mm deeper channel is made near the wall and floor junction in the soil, above the plinth. This channel has a hole at 150mm c/c distance. The solution is then poured into this hole at the rate of 7.5 liters for 1m2 of vertical surface area.
4. Treatment at the outer wall edges:
In this treatment, 300 mm deep pits are made at a distance of 150 mm c/c on the outside adjacent to the outer wall. The solution is then poured at the rate of 2.25 liters for a length of 1 m. The pit is then filled with clay.
5. Soil around the pipes:
Where the pipe enters or exits the building, the soil should be treated with termite resistant solution up to a distance of 150 mm on the outside and up to 300 mm on the inside.
6. Soil around the expansion joint:
The soil below the flooring should be treated with 2 liters of solution for 1 m length of joint length.
2. Post-construction Anti Termite treatment:
The various stages of post-construction termite resistant treatment are as follows:
- Observation of the building
- Soil treatment around the foundation
- Soil treatment under the floor
- Treatment of cavities in masonry
- Treatment of woodwork.
1. Observation of the building:
The purpose of the observation is to know how much termite was brought into the house and where it originated as well as which parts of the building were damaged.
2. Soil treatment around the foundation:
- In this stage the soil under the foundation and around the building is treated.
- A trench about 50 cm deep is dug on the outside of the outer wall of the building.
- Holes are drilled in this trench at a distance of 150 mm c/c with iron rods.
- This hole should be up to the top of the footing or at least 50 cm deep.
- The soil is then treated with 1.5 liters of solution per 1 m2 of surface area in contact with the soil.
3. Floor bottom soil treatment:
Where there are cracks in the floor, A 12 mm diameter hole is made at a distance of 300 mm c/c. The disinfectant solution is poured into this hole until the bottom soil is saturated.
4. Treatment of cavities in masonry:
This treatment involves drilling holes of 12 mm diameter at an angle of 45degree on the surface of both sides at the plinth level in the masonry wall at a distance of 300 mm c/c. An anti-termite disinfectant solution is poured into these pores.
5. Woodworking Treatment:
In this treatment, the wood is provided with a 6 mm diameter hole 130 mm c/c at an angle of 45degree towards the bottom. An oil based chemical solution is pumped in this hole.
