Anti-Termite Treatment After Construction
What is Anti-Termite Treatment After Construction? Anti-termite treatment after construction is a termite control technique used on a structure that is ready for occupancy or a home that people are already living in. This strategy is used when the insect invaders attack through the surface soil and spread within the building in search of food. Termites will emerge from the earth and damage all types of wooden furniture, doors and frames, among other things. Anti-termite treatment after construction is the best way to prevent further damage to structures that have been attacked by termites. It is unlikely that you will have to rebuild your building if termites are allowed to attack continuously throughout the year. Benefits of Anti-Termite Treatment Post-construction termite treatment can be done after the building is complete and ready for occupancy or even after it has been occupied. The floor will be slowly drilled with a drill to inject the chemicals, then covered again in almost the same state as it was before drilling.
Post-construction anti-termite method
Non-repellent/slow-acting chemical termiticides are particularly efficient when used to kill termites slowly by targeting their nervous system. When termites reach the treated soil they bring active termiticide to their colonies. In the coming days other colonies will be affected as a result of coming in contact with the individuals that have been poisoned by the chemical. As a result, the entire colony will be eliminated.
The following steps are taken during post-construction termite treatment:
Thorough inspection: The first step is to conduct a thorough inspection of the termite-infested structures. This is necessary to determine the point and direction of termite attack as well as the use of termite control measures in the structure.
Drilling on the floor: The second step is to use a drill to make a hole on the floor surface and inject anti-termite chemicals at a particular equally spaced location. Inject chemicals using injector: Anti-termite chemicals are injected in the hole to protect the structure from termites. Put bait inside and outside: If the inspection results indicate that termite bait should be put in the structure, then the bait will be put. Putting bait both outside and inside the colony is likely to harm the entire colony. Drill-Fill-Seal Method for Termite Control Drill-Fill-Seal is a method of drilling holes at the junction of walls and floor and injecting chemicals (termiticide solution) and then sealing them, used to avoid subterranean termite infestation. Holes of 12 mm diameter, spaced 20 inches apart, will be drilled at a depth of 12 inches at the ground and 4 inches at the upper levels along the internal junction. Termiticide will be sprayed under pressure, to install the termite barrier.
Operations involved in effective anti-termite treatment after construction
1. Thorough inspection
Inspection is carried out to determine the extent of termite infestation in the building as well as to identify the source of termite entry and the areas of the building that have been attacked.
The first part of the building to be inspected is that in contact with or next to the ground.
Basement, ground floor, stairs leading out of the ground, walls, columns, damp or humid places such as bathrooms, toilets, leaky pipes or drains, and places where woodwork is sunken into the floor or wall are all examples. Ceilings, wooden panelling, wire strands, conduits and switch boards are all places where termites hide and should be thoroughly inspected.
In multi-storey buildings the vents and covers of elevators, wells, electrical wires, telephone cables, water supply and soil pipes which serve as convenient and well-protected areas for termite infestation should all be thoroughly inspected.
2. Treatment of voids in masonry
Termites attack masonry foundations from the soil next to or below the structure, then move upwards through gaps in the masonry cracks to reach the interior.
To keep termites away from masonry voids, holes of 12 mm diameter are drilled with a centre to centre distance of 300 mm at a downward angle of about 45 degrees from either side of the walls at plinth level, and then chemical emulsion is injected into the holes until the masonry is fully saturated.
After that, the holes are sealed. This treatment is applicable to all walls with soil foundations.
At critical locations such as wall corners and places where door and window frames are embedded in the masonry at the lower level, the drilling holes should be treated and chemical emulsion should be poured.
3. Soil treatment for foundations
This treatment involves using a chemical emulsion to kill or repel termites in the soil beneath the structure and around the foundations.
Using a shovel, trenches approximately 500 mm deep are dug along the outer perimeter wall of the structures (the width of the trench being equal to the width of the shovel), and 12 mm diameter to 18 mm diameter holes are dug at 150 mm centres in the trenches near the wall face.
The holes should ideally reach the top of the foundations or to a depth of at least 500 mm, whichever comes first.
The holes are then filled with a water-based chemical emulsion, and when the backfill soil is returned to the trench, the chemical emulsion is sprayed over it, creating a toxic soil barrier around the perimeter of the structures.
The total amount of chemical used in this treatment should be 7.5 litres per square metre of masonry in the vertical surface of the foundations.
4. Treatment of wood work
Termite damaged wood should be replaced with fresh wood that has been properly brushed or dipped in oil or kerosene based chemical emulsion.
Drilling 6 mm diameter holes 150 mm centre to centre at a downward angle of 45 degrees to cover the entire structure and then injecting oil based chemical emulsion in the holes should be used to protect the infested wood work for door and window frames etc.
To prevent termites from attacking wood that is not infested, a chemical emulsion should be sprayed on it.
5. Treatment of termite mud tubes
Visible termite tubes will be destroyed by spraying, and termiticide will be applied on the infested area.
