Termite is a slow poison
Termites are a common and significant pest in warmer regions of the world, where structural timber can sustain significant damage.
Termite Trivia: When termite workers eat wood, they produce vibrations. The size of the wood influences the predominant resonant frequency of these vibrations. These vibration signals are detectable by the termites, who use them to determine the wood’s size. Termites appear to be able to use the vibration signals to make decisions about foraging, development, and reproduction based on the source of the signals.
Pre-Construction Treatement
Site preparation: All the waste wood, grass, stems, roots etc. lying buried or on the surface are to be removed.
Treatment of excavated foundation trenches: The bottom and sides of trenches up to a height of about 300 mm should be treated by applying insecticide solution (i.e., 4 liters of water with.25% to .5% of aldrin by weight or 0.25% to .5% of Heptachlor by weight) at the rate 5 liters/m of the surface area.
Pre-Construction Treatement
Treatment of back-fill soil: The back-fill used to fill the trenches after the masonry walls are constructed, should be treated with .5% of aldrin or .5% of Heptachlor by might. Solution should be applied on the vertical surface of the foundation masonry at the rate of 7.5% lit/m2(square), If the foundation is made of R.C.C., the treatment should be started at a depth about 0.5 m below ground level and the solution in the back fill at the rate of 7.5% lit/m2(square) of vertical surface to be given.
Treatment of filling at plinth level: Prior to laying of sub-grade for ground floor, the top surface often consolidated earth filling should be sprinkled with .5% of Aldrin/ Heptachlor at the rate of 5 lit/m2(square).
Soil treatment of foundation:
For this dig a trench about .5 m deep all along the wall drives 15 mm diameter holes
in the trench at 150 mm c/c. The holes are to be filled with chemical solution.
(.5% of aldrin/.5% of Heptachlor) at the rate 7.5 lit/m2(square) of vertical surface of the wall.
Soil treatment under floor:
All the joints/cracks of floor with walls, can be treated by drilling 12 mm dia. Holes
@ 300 mm c/c all along joints and filled with the chemical solution and then the face
of the holes to be sealed.
Post-Construction Treatment
Post-construction termite treatment refers to the use of pesticides or other methods to eliminate termites after a building has been constructed. This treatment is important for preventing further damage to the structure and preserving its integrity. The specific method used will depend on the severity of the infestation and the type of construction, and should be carried out by a licensed pest control professional. Regular inspections and preventative measures can also help prevent future termite damage.
