How do I know if my Nairobi home needs fumigation?

Watch for the signs above: cockroaches appearing in daylight, bites or rashes after sleeping, droppings in the pantry or under the sink, a musty smell that won't clear, or neighbours treating their unit. If you're seeing any of these repeatedly, the infestation is established and home remedies won't reach the nest.

How often should a home in Nairobi be fumigated?

It depends on your area, the pest and how the home is used. Many Nairobi homes do well with a preventive treatment every three to six months, while an active infestation needs an initial treatment plus a follow-up. We recommend an inspection first, then a schedule that matches your situation.

What is the difference between fumigation and pest control?

Pest control is the wider discipline — inspection, baiting, gel treatments, exclusion and monitoring. Fumigation is one method within it, where the treated space is filled with a professional product to reach pests hiding in cracks, furniture and wall voids. Serious infestations usually need fumigation plus the broader pest control measures around it.

How long should I stay away from my home after fumigation?

Your technician will give you a clear re-entry time before leaving. It's typically a few hours — long enough for the treatment to settle and the treated rooms to be aired out. Don't wipe down treated surfaces or let children and pets back in before that time.

Do I need to clean my house before fumigation?

Yes, basic preparation helps the treatment work better. Store open food and kitchen items, clear floors of laundry and toys, and give the team clear access along skirting boards and under furniture. We send a simple checklist before every visit so you know exactly what to do.

Can fumigation get rid of cockroaches completely?

A professional fumigation eliminates the active colony, including the roaches you never see. But in apartments and estates, roaches can return through shared drains and walls — which is why we pair treatment with hygiene advice and, where needed, a scheduled follow-up to break the cycle.

How much does fumigation cost in Nairobi?

Pricing depends on the size of your home, the pest being treated and how many rooms are affected, so we don't publish a one-size-fits-all figure. Share your details through our contact form or WhatsApp and we'll come back with a clear written quote — larger jobs start with a site visit.

How can I prevent pests from coming back after fumigation?

Remove what attracted them in the first place: store food in sealed containers, fix dripping taps and damp corners, take out rubbish regularly and seal gaps around pipes and doors. A follow-up inspection after a few months keeps small problems from becoming full infestations.

5 Signs Your Nairobi Home Needs Professional Fumigation

Feb 12, 2026 4 min read

Cockroaches at night, ants in the sugar, a musty smell that won't quit — here's how to tell when it's time to call the pros.

Nairobi's warm, humid pockets are a paradise for pests. Most homes cope with the occasional ant trail, but there's a point where store-bought sprays stop working — and that's when it pays to bring in a licensed team.

1. You see roaches during the day

Cockroaches are nocturnal. If you're spotting them in daylight, the nest is overcrowded and spilling into open spaces. That's a full-colony problem, not a spray-and-forget one.

2. Recurring bites or unexplained rashes

Bed bugs, fleas and mites often hide in mattress seams, sofa cushions and pet bedding. A professional fumigation treats the whole room at once so eggs don't hatch a fresh wave next week.

3. Droppings in the pantry or under the sink

Rodent droppings mean an active runway. Beyond the ick factor, they contaminate food surfaces — a real health risk for families with young children.

4. A musty, chemical smell that lingers

That smell is often a mix of pest pheromones and mould thriving in damp corners. A deep clean paired with fumigation clears both.

5. Neighbours are treating their unit

In apartments and gated estates, pests move through shared walls and drains. If the unit next door is being treated, book yours in the same week or the colony simply relocates.

One coordinated treatment beats six rounds of retail spray — every time.

What Zeb Clean does differently

Our Nyumbani and Afya packages combine a deep clean with targeted fumigation, so we're not just killing what's visible — we're removing the food, moisture and clutter that brought the pests in.
