Termite control in Karachi is structural risk control. The clay-loam alluvium under most of the city carries mature colonies of Coptotermes heimi and Heterotermes indicola within foraging range of almost every plot, and the humid monsoon window from late June to September drives the alate flights that seed new infestations into freshly poured slabs and freshly hung door frames. Add a building stock heavy with deodar, partal, and shisham timbers — attractive cellulose for Microcerotermes drywood species — and you get a city where untreated wood, given time, will be eaten. We are Nest Fumigation Services Private Limited, run by Saad Danish from a DHA Phase 4 office, and termite control is the highest-stakes category of work we deliver. This page walks through the species, protocols, chemistry, warranty, and pricing.
The three termites that damage Karachi buildings
Roughly 95% of termite jobs in Karachi come down to three species, and the protocol that works on one is the wrong protocol on the others. Species ID is the first and most consequential step of any termite job.
Coptotermes heimi is the dominant subterranean termite of the Indus plains. Mature colonies run to several hundred thousand workers, nesting three to five metres below foundation level and sending foraging galleries through expansion joints, plinth cracks, and any cellulose contact point. It is behind the dramatic damage cases — a door frame that crumbles when tapped, a wardrobe back that turns out to be paper-thin veneer, parquet floors lifting in patches. Mud tubes climbing a boundary wall in DHA, Clifton, or PECHS is the default Coptotermes signature.

Heterotermes indicola shares the soil-dependency but is smaller and more dispersed — colonies in the tens of thousands, several satellite nests per property rather than one central one. We see it most in older bungalows in Bahadurabad, Garden East, and inner North Nazimabad, where ageing boundary walls and buried construction cellulose give it niches. Damage is slower, patchier, and easier to miss for years.
Microcerotermes species — usually Microcerotermes championi in our field samples — are the drywood-behaving termites of Karachi. No soil contact required; they live entirely inside the wood they eat, in roof trusses, wooden ventilators, cupboard backs, antique furniture, and deodar rafters. They are why an upper-floor flat in Saddar with no garden can still have a termite problem. Evidence is frass pellets, not mud tubes. Deeper species breakdown at termite signs in Karachi.

How termite damage starts: mud tubes, wing dust, hollow wood
Most termite jobs are diagnosed late. Owners do not notice until something breaks — a skirting flexes underfoot, a door frame splits, a wardrobe back falls off. By then the colony has been active for months or years. Knowing the early evidence saves both the timber and the bill.
The most diagnostic sign of subterranean activity is a mud tube. Both Coptotermes heimi and Heterotermes indicola desiccate in dry air, so they build covered runways of soil glued with saliva and faecal matter between soil and food. A thin brown earthen line up a boundary wall, across a column, or behind a wardrobe is unambiguous. Coptotermes tubes are 5–8 mm wide and robust; Heterotermes tubes are thinner, often a fine network. Damp with cream workers means active; dry and abandoned means the colony has moved, rarely far.
The second sign is alate residue. Both subterranean species swarm after sunset following monsoon rain from late June to late September; Microcerotermes swarms in March–April and again in October. Swarmers fly briefly, land, shed wings, pair off. Piles of small translucent equal-length wings on a windowsill or under a tubelight — collect a few in a ziplock; it makes species ID much faster.
The third sign is frass — only for drywood. Microcerotermes expels six-sided faecal pellets, 0.5–1 mm long, the colour of the eaten wood, through small kick-out holes. They pile under the infested rafter. Coarse coffee-grounds-like material you cannot account for — get on the floor, look up, find the hole.
The fourth sign is hollow wood. Tap-test door frames, skirting, wardrobe bases, chowkat timbers. Sound timber has a clean solid note; damaged timber sounds papery. Push your thumbnail in — damaged wood often retains a thin intact outer veneer, which is why a door frame can look fine until you actually press it.
Pre-construction termite proofing: soil chemical barrier
The cheapest, most effective termite control you will ever buy on a Karachi property is the soil chemical barrier applied during construction, before flooring goes down. We apply the IS 6313 (Part 2): 2013 South Asian protocol as four integrated stages.
Stage 1 — Bottom of foundation trench
Once excavation is complete and before masonry goes in, we treat the bottom and sides of the trench with standard fipronil, applied at the label rate, at 5 litres of working solution per square metre. Where the owner wants the longer cover, the same stages are run with Agenda (fipronil) instead, which moves the warranty from seven years to ten.

Stage 2 — Refilled earth around the plinth
After the plinth wall is built and the foundation backfilled, we treat the refilled earth on both sides at 7.5 litres per linear metre, denying foraging workers a soil corridor against the structure.
Stage 3 — Top of plinth-fill, pre-flooring
The most important stage, and the one most often skipped on Karachi builds. Before the final earth is levelled inside the plinth and before any sand-cement bedding or tile goes down, we treat the top of the plinth fill at 5 litres per square metre across the floor footprint, plus a band along the inside perimeter wall. This is the barrier the slab and flooring will sit on for the whole warranty period.
Stage 4 — External perimeter drip line
Once construction is complete we treat external soil along the building's drip line at 7.5 litres per square metre to a 30 cm depth.
A complete four-stage pre-construction treatment with standard fipronil carries a seven-year warranty against subterranean penetration of the slab, or ten years with the Agenda upgrade (quoted on request). Pricing is PKR 18 to 35 per square foot of plinth area (see table below). Deeper pre-construction page, with the full proofing protocol, at pre-construction termite proofing.
Post-construction termite proofing: drill-and-inject
For an existing building, the soil chemical barrier is applied through drill-and-inject — our workhorse termite job, run weekly across DHA, Clifton, PECHS, Bahadurabad, Gulshan, and North Nazimabad to the IS 6313 (Part 3): 2001 protocol. A full drill-and-inject barrier around the building is termite proofing, not spot control, and it carries the same warranty as pre-construction work: seven years with standard fipronil, ten with Agenda.
Technicians mark out the inside perimeter of the ground floor and drill 12 mm holes at 30 cm spacing through the tile or screed into the plinth fill, 100–150 mm deep. Each hole is injected with standard fipronil, applied at the label rate, at 5 litres of working solution per square metre of slab area on the inside, with a parallel external trench-and-rod treatment along the drip line at 7.5 litres per square metre. Holes are sealed with matching cement plug — colour-matched on premium installations so the repair is invisible.
Where only one room or one wall run is active and the owner does not want a full barrier, we quote termite control instead: the infested zone is treated directly, and the warranty is one year. That is the honest trade-off — a spot job costs less, but it does not stop a colony from finding a new entry point elsewhere on the slab.
Residents re-enter once the drill points are dry, two to four hours in Karachi summer. Cooking, sleeping, and routine occupancy resume the same evening. Pets are kept off treated surfaces until completely dry. The protocol is decisive against both Coptotermes heimi and Heterotermes indicola — soil contact is the constraint they share, and an unbroken chemical barrier denies the access route.
When drill-and-inject is the wrong protocol
The drill-and-inject soil barrier is not decisive against drywood Microcerotermes on upper floors or in disconnected timber, because drywood termites never return to soil. If our inspection identifies frass-and-kick-out-hole evidence in third-floor rafters or cupboard panelling, we treat the timber directly (next section) rather than invoicing soil chemistry that would not solve the problem.
Wood treatment and timber injection
Drywood Microcerotermes and localised subterranean activity that has crossed into upper-floor timber require direct wood treatment. Two protocols.
Surface wood treatment — a wood-penetrating treatment applied to exposed timber surfaces (rafters, ventilator frames, cupboard backs, deodar trusses), diffusing into the wood fibre so any termite ingesting the cellulose takes it in. Odourless once dry. Protocol of choice for accessible drywood infestations.
Timber injection — for thicker structural members (deodar trusses, beams, lintels) we drill 6 mm holes at 30 cm spacing along the affected length and inject under low pressure, spreading the treatment through the gallery system. Drill holes plugged with matching wood filler. Decisive against established Microcerotermes colonies inside the timber.
We pair both with a surface treatment on adjacent untreated timber as a swarming-season barrier in March–April and October. Wood treatment is termite control, so it carries a one-year warranty on the treated members.
Warranty: what's covered and what voids it
Our termite warranty is structured around the protocol applied. No blanket guarantees that ignore building condition; we are explicit about exclusions at quote time.
Termite proofing — a complete four-stage pre-construction soil barrier, or a full drill-and-inject barrier on an existing building — carries a seven-year warranty with standard fipronil, or a ten-year warranty with the Agenda upgrade (quoted on request), against subterranean penetration of the treated slab, with one free callback per warranty year if new activity is observed in the treated footprint. Termite control — treating an active infestation without a full barrier, including spot drill-and-inject on one zone, wood treatment and timber injection — carries a one-year warranty with one free callback. The one-year control warranty is not extended by an AMC or by repeat visits; if you want long-term cover, the route is a full proofing barrier.
The warranty is voided by: a new flooring overlay or slab extension that breaks the treated barrier; a renovation that opens a new foraging route around the treated zone; structural alteration that exposes untreated soil under the slab; introduction of untreated infested furniture from another property; failure to report new activity within 30 days. We document warranty terms in writing on every job we close. For deeper cost discussion see termite treatment cost in Karachi 2026.

Frequently Asked Questions
Is termite chemistry safe for children and pets in Karachi homes?+
Used correctly, the risk is managed. Our proofing uses fipronil applied at the label rate into the soil under and around the slab, not onto surfaces people touch, and the drill holes are sealed afterwards. Keep children and pets off treated areas until they are dry — two to four hours in Karachi summer — after which the active is bound in the soil. We walk every household through re-entry timing before we start.
How long does termite treatment last in Karachi?+
Termite proofing — a full IS 6313 soil barrier, whether laid before construction or drilled and injected into an existing building — carries a seven-year warranty with standard fipronil, or ten years with the Agenda upgrade. Termite control, meaning treatment of an active infestation without a full barrier, carries a one-year warranty with no AMC extension. The warranty, not a residual estimate, is what we commit to in writing.
What voids a termite treatment warranty?+
A new flooring overlay or slab extension breaking the treated barrier voids the warranty over the affected area. A renovation opening a new foraging route, structural alteration exposing untreated soil, introduction of untreated infested furniture, or failure to report new activity within 30 days all void coverage. Soil-barrier chemistry only works while the barrier stays intact.
How do I identify which termite species is in my home?+
Look at the evidence. Wide robust mud tubes mean Coptotermes heimi; thin networked tubes mean Heterotermes indicola. Frass pellets in small piles under timber, with kick-out holes, mean drywood Microcerotermes. Upper-floor timber damage with no soil access is almost always Microcerotermes. Collect any swarmers, wings, or frass in a ziplock and our inspector will ID the species on site.
Can I do termite treatment myself instead of calling a professional?+
Surface spraying with a hardware-store pyrethroid kills surface workers and gives a few weeks of false comfort. It will not reach the soil colony, penetrate the gallery system inside infested wood, or establish a chemical barrier across the slab. Termite control is a barrier-and-chemistry job — label rates, application volumes, drilling pattern, and active selection all matter.
How long does a termite treatment visit take?+
A small zoned post-construction drill-and-inject — one affected room and its perimeter — takes two to four hours. A full villa treatment, drilling the entire ground-floor perimeter and the external drip line, takes one to two working days depending on plot size, access, and tile material. Wood treatment runs one working day per 60–80 linear feet of timber.
Is monsoon a bad time to treat for termites in Karachi?+
The opposite — monsoon is when subterranean termites are most active, alate flights happen, and treatment delivers the highest defensive value. We schedule drill-and-inject in dry windows between rain events so the fipronil binds to the soil before rain can flush it. On poorly drained properties we add a follow-up top-up six weeks later.
Do you offer a free termite inspection in Karachi?+
We charge PKR 2,500–4,000 for a residential termite inspection to cover inspector time and travel. If you book the treatment with us, the fee is credited in full against the job invoice. We charge upfront because honest inspectors often return "no work needed yet" answers without pressure to invoice. Call +92-311-1101810 to book a visit.
