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.
