Post-Construction Termite Treatment: Eliminating Deemak from Existing Homes
10 min read · Published 2026-08-24 · Updated 2026-09-15
15+ years of field experience inspecting termite activity and supervising soil-barrier and drill-fill-seal work across Islamabad and Rawalpindi. Checks every dosage, drill-spacing and price figure on this page against the jobs we completed in the last 12 months.
Mud tubes on the skirting, hollow-sounding door frames, blistered paint near the floor — these mean an active colony is already inside. Post construction termite treatment removes it from a finished house without tearing up your floors, and it is the job we perform most often in the twin cities.
- Post construction anti termite treatment uses inspection-led access points, soil treatment, sealing and follow-up.
- Non-repellent chemicals are essential: workers carry the dose back and the colony collapses.
- Termite injection treatment cost runs PKR 250–600 per drill point, or PKR 12–30 per square foot.
- Expect activity to drop in 3–7 days and full colony elimination in 4–8 weeks.
- Soil work stops the colony; damaged timber still needs anti termite treatment for wood.
How drill, fill and seal works
- 1Inspection and marking — the whole wall–floor junction is mapped, including bathrooms and stairs
- 2Drilling — access points sized and spaced to the registered label, construction and treatment zone
- 3Pressure injection — a lance forces termite injection treatment emulsion into the soil void beneath the slab
- 4Sealing — every hole is filled with matching white cement or grout
- 5External trench — a treated trench along the plinth closes the route from the garden
What the inspection must establish first
- 1Active evidence — mud tubes, live workers or soldiers, fresh timber damage and recent swarm points
- 2Likely termite type — subterranean activity needs a soil strategy; isolated drywood activity needs timber-focused treatment
- 3Construction route — slab edges, expansion joints, pipe sleeves, stair bases, ducts and attached planters
- 4Moisture source — leaking bathrooms, rising damp, roof discharge and irrigation against the plinth
- 5Hidden services — water, gas and electrical routes are checked before any hole is approved
Prepare the house for treatment day
- 1Move furniture far enough from marked walls for safe drilling and dust control.
- 2Remove food, medicines, toys and pet items from the immediate work area.
- 3Identify concealed pipes, underfloor heating, electrical conduits and valuable finishes.
- 4Cover aquariums and follow the product label for air pumps, birds and other sensitive animals.
- 5Agree the filler colour and take photographs of marble, tile and timber before work begins.
Where the work happens
The slab junction is the termites' motorway. Subterranean termite treatment saturates that soil so any worker crossing it picks up a lethal dose and shares it with the nest.
- 1Spacing wider than 12 inches leaves untreated gaps — the top reason cheap jobs fail.
- 2Bathrooms, kitchens and stair bases need extra points around pipe entries.
- 3Expansion joints and column bases are treated separately.
Anti termite treatment for wood means injecting existing galleries in door frames and battens, then brushing a preservative such as Solignum over bare timber. Practical household steps are in termite treatment at home.
- 1Drywood termite treatment targets insects inside the timber, not the soil.
- 2Treat the back and underside of furniture — that is where deemak enters.
- 3Fix damp plaster and leaks; moisture is the real invitation.
Old stumps, buried roots, wooden fence posts and compost heaps host colonies that simply walk back in. A treated trench along the outer plinth plus garden termites treatment stops re-infestation.
Never irrigate a lawn hard against a freshly treated wall — it washes the barrier out.
Judging the crew before they drill
- • Ask for the chemical name, brand and concentration in writing.
- • Confirm the drill plan and why its spacing suits the label and construction.
- • Insist on a written five to ten year warranty with free re-treatment.
- • Have holes sealed the same day with matching filler.
- • Accepting a surface spray sold as professional termite treatment.
- • Accepting sparse or unexplained drill points chosen only to keep the price down.
- • Choosing a repellent-only product for an active infestation.
- • Re-tiling or re-plumbing later without re-treating the broken barrier.
Follow-up: how success is judged
Do not judge treatment by smell or by the disappearance of one mud tube. Record every active location before application, leave agreed inspection windows accessible, and compare fresh mud, live insects and new timber damage at follow-up. Disturbing all tubes immediately can remove useful monitoring evidence. Persistent or new activity should trigger investigation of missed zones, leaks or a broken barrier—not repeated surface spraying.
Cost, warranty and the cheaper alternative
Budget PKR 12–30 per square foot; the per-drill-point breakdown of termite injection treatment cost is in our pricing guide. Chemistry choices are compared in termite treatment chemicals. If you are still building, do pre construction termite treatment instead — it costs about half.
Where we do this work
Most of our post-construction jobs are in older housing stock: termite treatment islamabad sectors F-6 through G-11, and termite treatment rawalpindi neighbourhoods like Satellite Town, Saddar and Cantt where houses are 30+ years old. Compare every option in types of termite treatment.
