The termite proofing a strategic planning for a premises to ensure that the natural soil which has termite infraction has to completely blocked by chemical emulsion to ensure no penetration of termites inside the treated premises.
1. Soil Treatment The object of soil treatment is to establish chemical (toxic) barrier between the termites in the soil and the building to be protected. Basically, it consists of treating the soil adjacent to or under the building with a chemical toxicant which kills or repels termites. Treatment along outside of foundations. The soil in contact with the external wall of the building shall be treated with chemical emulsion of the vertical surface of the sub-structure. If there is a concrete or masonry apron around the building, holes shall be drilled to the plinth wall deep enough to reach the soil below.
2. Treatment of soil under floors The points where the termites are likely to seek entry through the floor are the cracks at the following Locations:
Chemical treatment will be provided within the plinth area of the ground floor of the structure wherever such cracks are noticed, by drilling vertical holes at the junction of floor and walls, constructional and expansion joints.
3. Treatment to voids in masonry Termites are known to seek entry into masonry foundations and work their way up through voids in the masonry and enter the building at ground and upper floors. The movement of the termites through the masonry walls may be arrested by drilling holes in the masonry wall at plinth level and squirting chemical emulsion into the holes to soak the masonry. The holes shall be drilled at a downward angle preferably from both sides of the plinth wall and emulsion squirted through these holes to soak the masonry using a hand operated pressure pump. This treatment shall also be extended to internal walls having foundations in the soil. Holes shall also be drilled at critical points, such as wall comers and where door and window frames are embedded in the masonry or floor at ground. Emulsion shall be squirted through the holes.
4. Treatment at points of contact of woodwork All existing woodwork in the building which is in contact with the floor or walls and which is in contact with the floor or walls and which is infested by termites, shall be treated by spraying at the points of contacts with the adjoining masonry with the chemical emulsion by drilling holes at the junction of woodwork and masonry and squirting chemical emulsion into these holes.
5. Treatment of Woodwork For the purpose of treatment, woodwork may be classified as follows:
The woodwork which has already been damaged beyond repairs by termites should be replaced. The new timber should will be treated before use.
Infested woodwork in chaukats, shelves, joints, purlins, etc, in contact with the floor or the walls shall be provided with protective treatment by drilling holes with a downward slant to the core of the woodwork on the inconspicuous surface of the frame.
6. Treatment of Electrical Fixtures If infestation in electrical fixture (like switch boxes in the wall) is noticed, covers of the switch boxes should be removed and inside of such boxes shall be treated. The covers of the switch boxes shall be re-fixed after treatment.
