Termite Treatment

Termite treatment for Wood

Termite treatment for Wood

Wood work which is badly damaged by termites should be replaced by new timber which is adequately brushed or dipped in oil or kerosene based chemical emulsion. The infested wood work for door and window frames, etc. should be given protective treatment by drilling 6 mm dia holes at 150 mm centre to centre at a downward angle of 45 degree to cover the entire frame work and thereafter pumping oil based chemical emulsion into the holes. The wood work which is not attacked by termites should be sprayed over with chemical emulsion to prevent possible attack.

Termite – Soil Treatment under Floor

Termite – Soil Treatment under Floor

Cracks in floors are the weak spots which permit entry of termites from soil below the floor. The cracks usually occur at the junction of the floor and walls, expansion joints in floor and at construction joints in a concrete floor. Cracks in floors may also develop due to use of unsound materials or on account of defective workmanship. In such cases eradication of termites is achieved by poisoning the soil underneath the floors wherever such cracks are noticed. This operation is generally carried out by drilling 12 mm dia holes at 300 mm centre to centre all along the cracks in the floors in different areas and then injecting chemical emulsion into the holes till the soil below gets fully saturated. The maximum quantity of chemical emulsion, however, not exceed one litre per hole. The holes in floors are sealed after termite treatment.

Termite- Soil Treatment for Foundations

Termite Treatment for Foundations

This termite treatment consists in treating the soil under the building and around the foundations with some chemical emulsion which can kill or repell termites. In this termite treatment about 500 mm deep trenches arc made along the external peripherial wall of the building with the help of shovel (width of the trench being equal o the width of the shovel) and 12 mm dia to 18 mm dia holes at 150 mm centres are then made in the trenches close to the wall face with the help of iron rod. The holes should preferably extend upto the top of footing of foundations or to a depth of at least 500 mm whichever is lesser. The holes are then filled with chemical emulsion in water and the hack fill earth is also sprayed with the chemical emulsion as it is returned to the trench thereby creating a barrier of poisoned soil along the external, periphery of the building. The total quantity of the chemical to be used in this termite treatment should be 75 litres per sq. m of the vertical surface of the masonry in foundation.

In case of RCC frame structure, the chemical treatment shall he applied to the soil in contact with column sides and plinth beams along external periphery of the building for a depth of 500 mm below ground level.
