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.
