Accurate Small Rust-Coloured Spots
Tiny dark or rust-coloured spots on mattress seams, sheets, and pillowcases are usually bed bug excrement or crushed blood spots — one of the earliest and most reliable signs of an active infestation.
2-Stage Treatment — Spray + Gas Fumigation
Bed Bugs Fumigation Service in Karachi — Eggs, Nymphs & Adults, Eliminated in One Visit
Bed bugs hide in mattress seams, bed frames, skirting boards, and wall junctions — places a single spray can never fully reach. Accurate Fumigation uses a two-stage protocol: a residual insecticide spray across every harborage area, followed by gas tablet fumigation that penetrates cracks, seams, and voids to reach eggs and bugs that sprays alone leave behind. Free inspection, written 3-month warranty, and WHO-approved chemicals — odourless option available for homes with children, elderly residents, or pets.
Identifying the Problem
Signs You Have a Bed Bug Infestation
Bed bugs are nocturnal, fast-breeding, and excellent at hiding — most homeowners don't see the insects themselves until the infestation is already established. These are the signs our inspectors look for, and the signs you can check for yourself before calling us.
Bites in a Line or Cluster
Itchy, red bite marks appearing in a line or small cluster on arms, legs, neck, or back after sleeping — often noticed on waking and not present the night before — are a classic indicator of bed bug activity.
Live Bugs or Shed Skins
Adult bed bugs are flat, reddish-brown, and roughly the size of an apple seed. Look along mattress seams, bed frame joints, and headboard cracks for live bugs, eggs, or the pale shed skins they leave behind as they grow.
A Sweet, Musty Odour
Heavy infestations often produce a faint, sweet, musty smell — sometimes compared to overripe berries — caused by scent glands. If the smell is noticeable on entering a bedroom, the infestation is usually well established.
Dark Stains on Furniture Seams
Check the piping and seams of sofas, mattress edges, bed frame joints, and skirting boards for small dark smear marks — these are often missed during routine cleaning and are prime harborage zones.
Recently Acquired Furniture or Travel
Bed bugs commonly enter homes via second-hand furniture, mattresses, or luggage from travel and hotel stays. If bites or marks appeared shortly after acquiring used furniture or returning from a trip, this is a strong clue.
Our Treatment Protocol
How We Treat Bed Bugs — Step by Step
A single spray treatment often fails against bed bugs because eggs survive in protected crevices and hatch days later. Our protocol is built around this reality: a thorough inspection, a residual spray stage, and a gas tablet fumigation stage that reaches what sprays cannot — all backed by a written warranty.
Step 1 — Free Property Inspection
Full Property Inspection & Harborage Mapping
Our technician inspects every affected area of the property — mattresses, sofa sets, bed frames, headboards, curtains, skirting boards, electrical sockets, and wall junctions — to assess the severity of the infestation and map out all active harborage sites. This step determines exactly which rooms need the spray stage, which need gas tablet fumigation, and which need both.
No call-out fee No obligation to proceed
Step 2 — Stage 1: Targeted Spray Treatment
Residual Insecticide Spray on All Identified Surfaces
A WHO-approved residual insecticide is applied directly to every surface and crevice identified during the inspection — mattress seams, bed bases, sofa sets, curtains, pillows, carpets, and skirting board joints. This stage kills exposed adults and nymphs on contact, while leaving a residual layer on treated surfaces that continues working against bugs that emerge from hiding over the following days.

Step 3 — Stage 2: Gas Tablet Fumigation
Fumigant Gas Tablets for Cracks, Seams & Voids
After the spray stage, fumigant gas tablets are placed strategically throughout each treated room. As the tablets release fumigant gas, it spreads into every crack, seam, electrical void, and wall cavity — reaching eggs and bugs hiding in places no spray nozzle can access. This is the stage that gives our protocol an edge over single-method treatments: it targets the eggs that would otherwise hatch and restart the infestation. The treated room must remain sealed and unoccupied for 24 hours for the gas to fully penetrate and then dissipate safely.
Room sealed for 24 hours after placement Reaches eggs sprays cannot
Step 4 — Written Warranty Issued
3-Month Written Warranty Certificate
Once both stages of treatment are complete and the seal period has ended, you receive a written warranty certificate covering the treated areas for 3 months. If bed bugs are found in those areas within the warranty period, we return and carry out a full re-treatment at zero additional cost — no phone-tag, no conditions, no arguments. The certificate also documents the chemicals used, treatment date, and technician name for your records.

Why Two Stages
2-Stage Treatment vs. Spray-Only Treatment
Many local operators offer a single spray visit and call it complete. The problem is that bed bug eggs are protected from contact sprays and can hatch 6 to 10 days later — restarting the infestation. Here is how a spray-only approach compares to our 2-stage protocol.
| Treatment Aspect | Spray-Only Treatment | Accurate Fumigation 2-Stage |
|---|---|---|
| Kills adult & nymph bed bugs | ✓ Yes, on contact | ✓ Yes, on contact |
| Reaches eggs in cracks & voids | ✗ Limited reach | ✓ Gas penetrates voids |
| Risk of re-infestation from hatching eggs | ✗ Higher | ✓ Significantly reduced |
| Residual protection after treatment | ~ Varies | ✓ Residual layer left on surfaces |
| Written warranty | ✗ Rarely given | ✓ 3 months, written |
| Free re-treatment if bugs return | ✗ Usually chargeable | ✓ Included in warranty |

Before Our Visit
How to Prepare Your Room for Bed Bug Treatment
A small amount of preparation before our team arrives helps both treatment stages work more effectively. Our technician will confirm exactly what's needed for your property during the inspection, but the general guidance below applies to most homes.
Strip and Wash Bedding
Remove all bedding, pillowcases, and curtains from affected rooms and wash them on the hottest setting the fabric allows, then dry on high heat. Heat is highly effective at killing bed bugs and eggs in fabric items.
Clear Wardrobes & Drawers
Empty drawers and wardrobe shelves near beds and seating so technicians can access skirting boards, joints, and corners directly. Clothing can be left in sealed plastic bags during the gas tablet stage.
Remove Food, Medicines & Pet Items
Take open food, medicines, pet bowls, and toothbrushes out of the rooms being gas-treated. Sealed packaged food can remain. Our technician will confirm exactly what needs to be removed for your specific treatment plan.
Plan to Be Away for the Seal Period
The gas tablet stage requires the treated room to be sealed and unoccupied for 24 hours. Plan to use unaffected rooms, or arrange to be away from the property during this window — our team will schedule around your routine where possible.
Move Furniture Slightly Away From Walls
If possible, pull beds, sofas, and wardrobes a few inches away from the walls before our visit. This gives technicians clear access to skirting boards and wall junctions — common bed bug pathways between rooms.
Note Down All Affected Rooms
Make a quick list of every room where you've seen bites, spots, or live bugs — including guest rooms and sofas — and share it with our inspector. Bed bugs travel between adjoining rooms, so a complete picture leads to a more effective treatment plan.

What Karachi Clients Say About Our Bed Bug Treatment
Real clients from real areas of Karachi describing their experience with our 2-stage bed bug protocol.
★★★★★
"We had a serious bed bug infestation in our flat in Johar — three mattresses affected. Accurate Fumigation's team came the next day, explained every step, and used odourless chemicals. Follow-up visit done on time. No sign of bugs after three months."
Zubair Baig
Gulistan-e-Johar · Bed Bug Treatment
★★★★★
"Bought a second-hand sofa and within two weeks started getting bites every night. The team explained that gas tablets were needed alongside the spray because of where eggs hide. Sealed the room for a day and it's been clean since — three months and counting."
Sara Hashmi

Common Questions
Frequently Asked Questions — Bed Bug Fumigation
The questions Karachi clients ask most before booking bed bug treatment.
A typical one-to-two bedroom property takes between 2 and 4 hours for the spray and gas tablet stages combined. After placement of the gas tablets, the treated rooms must remain sealed for 24 hours for the fumigant to fully penetrate cracks, seams, and voids. Larger properties or heavier infestations may require additional time and a follow-up visit, which we will explain clearly during the inspection.
For the spray stage, residents are usually asked to vacate the treated rooms for 2 to 4 hours. For the gas tablet stage, the treated rooms must be sealed and unoccupied for a full 24 hours, as the fumigant needs that time to work and then dissipate. We schedule the gas stage so you can use unaffected parts of the property, or plan around an overnight absence if every room is being treated.
Bed bugs lay eggs in protected crevices that a single spray cannot always reach, and eggs can hatch after the first treatment. That is why our protocol combines a residual spray with gas tablet fumigation in the same visit, and includes a written 3-month warranty with a free re-treatment if bed bugs return within that period. Severe, long-standing infestations sometimes need a scheduled follow-up visit, which we will explain clearly during the inspection.
The fumigant tablets we use are formulated for indoor structural fumigation and do not damage furniture, mattresses, wooden frames, or standard electronics when used according to protocol. We advise removing sensitive items such as open food, medicines, and pet bowls from the treated room before placement. Once the 24-hour seal period ends and the room is ventilated, everything can be used normally.
The cost depends on the number of rooms affected, the severity of the infestation, and whether the gas tablet stage is required for the full property or specific rooms only. We do not quote fixed prices without a free inspection, because pricing without seeing the property would either overcharge or undercharge the client. After the inspection, you receive a written, itemised quote before any work begins.
Bed bugs can be reintroduced from outside the property — through luggage, used furniture, or visitors — even after a fully effective treatment. This is exactly why we issue a written 3-month warranty: if bed bugs are found in the treated areas within that period, we return and re-treat at zero additional cost. We also provide simple prevention guidance to reduce the chance of reintroduction.
All chemicals used are WHO-approved and certified for indoor residential use, with an odourless option available on request. For the spray stage, we recommend children, elderly residents, and pets vacate the treated room for 2 to 4 hours. For the gas tablet stage, the room must be completely vacated and sealed for 24 hours. Our technician will confirm the exact timing for your household before treatment begins.
