Pre-Construction Termite Treatment in Karachi
Pest Tech has provided pre construction termite treatment in Karachi since 2005. We treat the soil at each building stage — foundation pits, plinth or DPC level, under the floor before concrete, and the outer perimeter — so the whole footprint sits on a treated barrier, and we issue a warranty certificate once the final stage is done.
Signs you have a termite problem
On a new site you will not see termite damage yet — that is the point. What you can see are the conditions that invite a colony into a new building, and on Karachi plots they are common:
- Old tree roots, stumps or wooden formwork buried in the plot
- Termite mud or runways on boundary walls of neighbouring houses
- Filling soil brought in from open land in Scheme 33, Malir or the Superhighway belt
- Low-lying plots where water stands after the monsoon
- Wooden door frames, shuttering or scaffolding stored on bare soil at site
- A builder or bank that requires a termite treatment certificate at handover
Our termite treatment process
- 01
Site visit and stage plan
We visit before excavation or as soon as possible after, measure the plinth area and agree a stage schedule with your contractor so the treatment happens before each layer is covered.
- 02
Stage 1 — foundation pits and trenches
The bottom and sides of foundation pits and trenches are treated before concrete is poured, soaking the soil the footings will sit on.
- 03
Stage 2 — plinth / DPC level
The soil in contact with the plinth walls and the damp-proof course level is treated as the walls come up, closing the gap where termites climb from soil to masonry.
- 04
Stage 3 — before floor soling and concrete
After the floor is levelled and compacted, and just before soling and concrete, the whole under-floor area is treated so termites cannot come up through cracks or joints later.
- 05
Stage 4 — outer perimeter and certificate
Once the plinth is complete, a trench along the external perimeter is treated and back-filled. We then issue the warranty certificate with the stages, dates and product used.
How much solution goes in at each stage?
The dose is set by the termiticide label, not by guesswork. As an example, the label of a termiticide commonly used in Pakistan gives 5 litres of diluted solution per 10 square feet of treated soil surface at each stage. That is typical label guidance; the exact dose and dilution always follow the label of the product used on your site, and we record both on your certificate.
Why the dose matters:
- Under-dosing leaves gaps in the barrier, and termites find gaps.
- Soil type changes absorption — sandy fill in Karachi soaks solution fast, clay holds it at the surface — so the technician adjusts application to reach the required volume evenly.
- Treated soil must be covered soon after application; leaving it exposed to sun and rain for days weakens it.
We use non-repellent termiticides such as fipronil or imidacloprid, or a bifenthrin barrier where appropriate, applied with calibrated equipment.
Coordinating with your builder
Pre-construction treatment only works if it happens at the right moment. The most common failure on Karachi sites is a floor poured before the under-floor stage was treated. To avoid that:
- Share your contractor’s phone number with us; we confirm each stage directly.
- Tell us 24–48 hours before pits are ready, the plinth is complete and the floor is levelled.
- Keep treated areas free of fresh fill and debris until they are covered.
- Store timber and door frames off the ground on bricks, not on bare soil.
For large projects — apartment blocks, factories and schools — we assign one supervisor to the site and keep a stage log you can hand to the client or bank.
Pre-construction vs post-construction
Treating during construction is cheaper and more complete than drilling later, because every square foot of soil under the building can be reached. If your building is already finished, see termite control for existing homes.
Pests covered
- Subterranean termites
- Mound-building termites on open plots
- Drywood termites in stored timber
Safety for children, pets and food areas
- Treatment is applied to soil that is then covered by concrete or back-fill — nothing is applied to living areas.
- Workers on site keep away from freshly treated soil until it has soaked in; our technician marks the area.
- Solution is mixed at the site in closed containers and leftover solution is never poured into drains or water tanks.
- Keep children and animals away from the site during application; your technician confirms when the area can be walked on.
- You receive the product name, dose and stage dates on the certificate.
How much does pre-construction termite proofing cost in Karachi?
Pre-construction termite treatment is priced on the plinth area in square feet and the number of stages, with a minimum per site. Larger projects are quoted per phase. The termite calculator gives an instant estimate for pre- and post-construction work; the final price is confirmed after a site visit.

Pre-Construction Termite Proofing: frequently asked questions
Before excavation is finished, ideally when the foundation pits are being dug. We then schedule each stage with your contractor.
Usually three core stages — foundation pits, plinth/DPC level and under-floor before concrete — plus the outer perimeter once the plinth is complete. Your quote lists every stage.
Generally yes, per square foot, and it is more complete because the whole footprint is treated. Post-construction drilling can only reach along walls and joints.
A correctly dosed soil barrier typically protects for many years; we state the warranty period on your certificate and offer annual inspections.
Then that area is treated post-construction by drilling. Tell us straight away so we can adjust the plan and the certificate.
Yes — a written warranty certificate listing the site, stages, dates, product and dose.
