“Termite, by nature, will forage until they find a food source”. During their foraging efforts, if they encounter a barrier like those from organophosphates and pyrethroids, they will detect it and be repelled. If the barrier is continuous, with no gaps, this treatment can be successful because the structure will remain protected. If the barrier is not complete, though, the termites will continue their meticulous foraging behavior until they find a break and can reach the food source. Repellent and contact mortality termiticides can immediately kill termites and protect structures from damage.

1) Post-Construction Anti Termite Soil Treatment

Horizontal barriers

The sub-construction of the building is comprehensively treated in a grid pattern by injection through the floors and the walls of the building or by long rodding. The objective is to create a total horizontal barrier by ensuring that the drill holes are close enough together to provide confluent applications into the soil beneath. The rate application is 5 liter per square meter of the floor area treated. All holes drilled into or through the structural elements of the building must be securely plugged after treatment. Post-construction soil applications are made by injection with a nozzle pressure at 25 p.s.i. Rod holes are trenches should not extend below the footing because of the possible of soil wash out by the spray. Before applications into the soil are made, we will identify the paths of all services into the building so that these are not damaged in the application process.

2) Pre-Construction Anti Termite Soil Treatment

Horizontal barriers

Before the footings are poured, horizontal barriers may be established in the footing trenches. Then after site preparation is completed and prior to the pouring of slab floors or platforms treatment will follow. Termiticide will be applied at the rate of 5 liter per square meter of the area. It is important that steady even coverage is obtained with applications made by low pressure spray (less than 50 p.s.i.) using a coarse spray nozzle.

Usual techniques will be used to protect the treated area before pouring of the slab material. This normally involves covering the area with polythene sheet. In situation where this is not standard procedure, if there is delay of more than 24 hours in pouring the slab, cover the treated area with an opaque polythene sheet to protect the treatment from ultra violet light and rain.

Vertical barriers

Vertical barriers will be effectively established in areas around the base of the foundation, piers, plumbing entrances and exits, utility entrances, back-filled soil against foundation walls or other key positions which require more than a horizontal barrier because they give access to the building.
