Most people in Karachi hire a pest control company the way they flag down a rickshaw — on price, on the spot, on whoever picks up first. Then the cockroaches return in three weeks, the "termite treatment" turns out to be diluted kerosene, and there is no warranty, no report, and no one answering the number. The problem is not that good providers do not exist — it is that a sprayer with a drum and a good sales voice looks identical to a licensed operator until you ask the right questions.
We are Nest Fumigation Services Private Limited, a Karachi pest-control company based in DHA Phase 4 and founded by Saad Danish. We wrote this page as a buyer's checklist — not a sales pitch. Use it to vet any provider you are considering. Ask these 11 questions, listen for the answers described below, and you will screen out the overwhelming majority of unqualified operators before they set foot in your home or facility. At the end we note where we stand on each — because a company that asks you to demand these things should meet them itself.
Print it, screenshot it, or read it down the phone. Each question tells you why it matters and what a good answer sounds like.
1. Are you licensed, and are you a member of SPMA or PPMA?
Why it matters. Pakistan's pest-management industry has a legitimate professional layer — the Structural Pest Management Association (SPMA) and the Pakistan Pest Management Association (PPMA) — and an informal layer of unregistered sprayers with no accountability. Membership is not a legal licence to spray, but it is the single fastest filter: registered firms carry business registration, follow association conduct standards, and have a reputation to lose. Unregistered operators have neither.
What a good answer sounds like. "Yes — we are a registered private limited company and members of SPMA and PPMA. We also hold ISO 9001:2015 certification and are members of the Karachi Chamber of Commerce and Industry." A vague "everyone knows us, we've been doing this for years" is not an answer. Ask for the registration in writing.
2. What chemicals do you use — and can you show me the label or MSDS?
Why it matters. The active ingredient is the treatment. Everything else is water and marketing. A real company knows exactly what it applies, at what concentration, and can produce the product label and Material Safety Data Sheet (MSDS). Someone who says "special medicine" or "imported spray" without naming an active is either hiding a cheap generic or does not know. Concentration matters too: for termite soil treatment the honest figure for imidacloprid [1] is 17.8% SC (Premise 200 SC) — if a salesperson quotes an inflated "30.5%" to sound stronger, that is a red flag, not a feature.
What a good answer sounds like. Specific actives, named: Fipronil [2] 0.05% gel bait for cockroaches (Blattella germanica), Imidacloprid 17.8% SC for subterranean termites (Coptotermes heimi), Bti (Bacillus thuringiensis israelensis) as a larvicide for mosquito breeding (Aedes aegypti [3]). A good provider will show you the label and explain re-entry times without being pushed. See our cockroach treatment page for how gel baiting actually works.
3. What warranty do you give — in writing?
Why it matters. A verbal "guaranteed" means nothing when the ants come back. A written warranty tells you the company stands behind its chemistry and its workmanship, and it defines exactly what happens if pests return. It also tells you they used a treatment strong enough to warrant one. No paper, no promise.
What a good answer sounds like. Warranty terms that match the biology of the pest, for example: termite proofing (pre-construction) 10-year written warranty; post-construction termite treatment 1-year plus a 5-year AMC option; cockroach general treatment 6-month; bed bug treatment 3-month. Short-lived pests get shorter warranties, structural work gets longer ones — that is how you know the terms are real and not plucked from the air.
4. Is your team trained, uniformed, and background-checked?
Why it matters. You are letting strangers into your home, kitchen, and bedrooms, often when family members are present. The people who arrive should be trained technicians who know dose rates and safety, not day-labour handed a sprayer that morning. Uniforms, ID, and background screening are basic markers of a company that manages its staff rather than assembling a crew per job.
What a good answer sounds like. "Our technicians are trained in-house on chemical handling and IPM, arrive in company uniform with ID, and are vetted before hiring." For a home visit you have every right to ask that identifiable, uniformed staff attend.
5. Do you provide service documentation and reports?
Why it matters. Professional pest management is documented. A report tells you what was found, what was applied where, at what dose, and what to expect next — and it is the record you will need if pests recur under warranty or if you are ever audited. Operators who leave nothing behind leave you nothing to hold them to.
What a good answer sounds like. "You receive a service report after every visit — pest activity observed, products and doses applied, areas treated, and recommendations. For contract clients we maintain logbooks, monitoring records, and trap trend data." For commercial sites this documentation is not optional; it is the audit trail (more in question 11).
6. Do you use IPM, or do you just spray?
Why it matters. Blanket spraying knocks down the pests you can see and does nothing about why they are there — the leaking pipe, the gap under the door, the uncleared grease trap. Integrated Pest Management [4] (IPM) treats the infestation as a system: inspect, identify, exclude, sanitise, and apply chemistry only where it is actually needed. It costs a little more to think, and it is the difference between a treatment that lasts and one that resets every month.
What a good answer sounds like. "We start with an inspection and identification, fix the conditions driving the infestation — entry points, moisture, harborage — and target chemistry precisely rather than fogging everything." That is IPM. See our IPM services for how the framework is applied across Karachi sites.
7. Is the treatment safe around children, pets, and food?
Why it matters. The most common real-world harm from pest control is not the pests — it is careless application near a child's cot, a pet's bowl, or an open food shelf. A professional matches the method to the environment: gel baits in gel-appropriate places, re-entry intervals honoured, food surfaces protected or avoided. "It's totally safe, don't worry" is the answer of someone who has not thought about it.
What a good answer sounds like. "We use targeted gel baiting and low-odour, food-safe options in kitchens, tell you exactly how long to keep children and pets out of treated areas, and ask you to cover or clear food beforehand." A specific re-entry time — for instance, keep clear for a stated number of hours — is the mark of someone who knows the product.
8. How fast is your callback if pests return between visits?
Why it matters. Even a good treatment sometimes needs a follow-up — a stubborn German cockroach pocket, a bed bug egg hatch after the residual window. What separates a professional from a one-and-done sprayer is what happens when you call back. A defined response time (an SLA) means the warranty is real and someone owns the outcome.
What a good answer sounds like. "If pests return within the warranty period, call us and we re-treat free within a stated turnaround — usually a day or two — no argument." Pin down the number and confirm it is written into the warranty, not just spoken.
9. Is your pricing transparent and itemized?
Why it matters. A single vague lump sum hides what you are actually paying for — and lets the number drift upward once work begins, or the chemistry drift downward to protect the margin. Itemised pricing (area treated, pest, method, number of visits, warranty) lets you compare providers on like-for-like terms and holds the quote honest.
What a good answer sounds like. "Here is the breakdown — treatment type, coverage area, number of visits, warranty period, and price per item." A company confident in its value shows you the maths. Our published pest control prices for Karachi (2026) exist precisely so buyers can see real numbers before anyone visits.
10. Can you provide references or verifiable reviews?
Why it matters. Anyone can claim to be the best in Karachi. Verifiable proof is different: a public Google Business Profile with a real review history, client references you can actually call, a traceable business address. If the only evidence is the salesperson's own word, you have no evidence.
What a good answer sounds like. "Here is our Google Business Profile — read the reviews — and here are commercial clients you may contact." For reference, we hold 175 Google reviews at 4.9 stars on a two-year-old profile and a fixed business address in DHA Phase 4. Look for depth and recency, not a handful of five-star lines posted the same week.
11. Do you handle compliance work (HACCP, Sindh Food Authority) if I am a commercial site?
Why it matters. If you run a restaurant, food factory, pharmacy warehouse, hotel, or any regulated facility, pest control is not just about killing pests — it is an audit line item. Sindh Food Authority [5] (SFA) inspectors and HACCP or GFSI auditors want a documented pest-management programme, a monitored-substance list, trap maps, and closed corrective actions. A residential sprayer cannot produce any of that, and hiring one puts your licence at risk.
What a good answer sounds like. "Yes — we run audit-ready IPM with a written programme, monitored-substance records, trap networks, and trend reporting aligned to HACCP and SFA requirements." See our commercial pest control in Karachi and HACCP pest control Pakistan pages for the full framework.

Frequently Asked Questions
What is the single most important question to ask a pest control company?+
If you can only ask one, ask to see the chemical label or MSDS for what they will apply. It instantly reveals whether they know their own treatment, whether the active is legitimate (for example Fipronil 0.05% gel or Imidacloprid 17.8% SC), and whether the concentration is honest. Everything else — warranty, IPM, safety — follows from a company that actually knows its chemistry.
Is a cheap pest control quote always a bad sign in Karachi?+
Not always, but a suspiciously low price usually signals one of three things: a diluted or generic chemical, no warranty, or no follow-up visits. Ask for an itemised quote and a written warranty. If the low price still includes named actives, documentation, and a callback guarantee, it may be genuine value. If it is a vague lump sum, it is cheap for a reason.
Should a pest control company give a written warranty?+
Yes. A reputable provider puts warranty terms in writing, matched to the pest — for example around 10 years for termite proofing, 1 year plus a 5-year AMC for post-construction termite work, 6 months for cockroaches, and 3 months for bed bugs. A verbal guarantee with nothing on paper is effectively no guarantee at all.
How do I know if a pest control treatment is safe for my children and pets?+
Ask for the specific re-entry time — how many hours to keep the area clear — and whether food-safe, low-odour options are used in kitchens. A professional will give you a definite interval and instructions to cover food and keep children and pets away. Vague reassurance without a re-entry time is a warning sign.
What is IPM and why should I ask about it?+
IPM (Integrated Pest Management) means inspecting and fixing the causes of an infestation — entry points, moisture, food sources — and applying chemistry only where needed, rather than blanket spraying. It produces longer-lasting results and less unnecessary chemical exposure. Asking about IPM separates providers who solve the problem from those who just knock down what is visible today.
Do I need a HACCP-compliant provider for a restaurant or food business in Karachi?+
Yes, if you are subject to Sindh Food Authority inspection or any food-safety audit. You need a provider who supplies a documented pest-management programme, monitored-substance records, and trap-monitoring reports. A residential sprayer cannot meet these requirements, and using one can put your food licence at risk during an audit.
How many Google reviews should a trustworthy pest control company have?+
There is no magic number, but look for depth, recency, and a profile that is at least a year or two old — steady genuine reviews over time beat a burst of five-star lines posted the same week. Also check that the company has a fixed, verifiable business address, not just a mobile number.
