Quick answer: Fumigation price list Nairobi 2026

Here is the full fumigation cost in Nairobi for 2026:

Prices above are estimates for Nairobi and the surrounding areas as of 2026. Exact quotes depend on infestation severity, property condition, and the company you choose.

What affects fumigation cost in Nairobi?

Understanding what drives the price helps you negotiate fairly and avoid being overcharged.

1. The size of your property

This is the single biggest cost driver. A larger property requires more chemicals, more technician time, and more thorough treatment of all rooms and hidden areas. Fumigation services cover your entire home rather than spot-treating, which means cost rises proportionally with the size of your property. Imagine Care Limited. Always measure your property in square metres before requesting a quote — a company pricing per square metre is usually more transparent than one giving a flat-rate figure.

2. The type of pest

Not all pests are equally difficult to eliminate. Cockroach and mosquito treatments are generally straightforward and affordable. Bed bugs and termites, however, require specialist chemicals, multiple treatment stages, and often follow-up visits. Pests like ants and spiders may be easier to control and therefore less expensive, while others like termites or bed bugs may require more intensive treatment and cost significantly more. Imagine Care Limited. Always confirm the exact pest you are dealing with before comparing prices — a bed bug quote and a general fumigation quote are not the same thing.

3. Severity of the infestation

A minor cockroach problem caught early costs far less to treat than a heavy infestation that has spread through walls and under flooring. The cost of pest treatment depends significantly on both the severity of the infestation and the size of the property. Imagine Care Limited If you wait too long to call a professional, you will pay more — both in treatment costs and in property damage.

4. The chemicals and methods used

There is a significant difference between a company using Pest Control Board of Kenya-approved, non-toxic insecticides and one buying unregistered chemicals from an agro shop. Professional-grade, child-safe, and pet-friendly formulations cost more to source — but they are safer for your family and more effective long-term. Always ask which specific chemicals will be used and confirm they are PCPB-registered.

5. The reputation and licensing of the company

Registered, licensed pest control companies typically charge a fair premium over unregistered operators. That premium buys you accountability, warranty, and the assurance that trained technicians are handling chemicals safely in your home. A cheap fumigation that fails — or damages your furniture or family’s health — is far more expensive in the end.

6. Your location within Nairobi

Properties in areas that are further from a company’s base of operations may attract a travel surcharge. If you are in Ruiru, Rongai, Thika, or Kiambu, confirm upfront whether a call-out fee applies. Most reputable companies serving Nairobi and surrounding counties absorb travel costs within their standard pricing.

Fumigation cost by pest type in Nairobi

Bed bug fumigation Nairobi — KSh 3,500 to KSh 20,000

Bed bugs are among the most difficult and expensive pests to eliminate in Nairobi. Bed bug fumigation cost in Nairobi ranges from KSh 7,000 to KSh 20,000, depending on the severity of the infestation and the size of the property. Imagine Care Limited. Effective bed bug treatment usually requires a combination of heat treatment and chemical spraying, plus a follow-up visit to catch any newly hatched eggs. Be wary of any company quoting under KSh 4,000 for a full bed bug treatment — at that price, the job will not be thorough.

Cockroach fumigation Nairobi — KSh 3,500 to KSh 8,000

Cockroaches are the most common pest in Nairobi’s apartments and commercial kitchens. A standard treatment for a 2–3 bedroom home typically falls between KSh 3,500 and KSh 7,000. For restaurants, hotels, and food-handling businesses, a more thorough treatment is required and prices rise accordingly. Regular quarterly treatments are recommended for commercial kitchens to stay compliant with health regulations.

Termite control Nairobi — KSh 8,000 to KSh 30,000+

Termite infestations are the most serious — and most expensive — pest problem a property owner in Nairobi can face. Termites work silently inside walls and foundations, and by the time they are visible, significant structural damage may already have occurred. Annual contracts for ongoing pest control services in Kenya can range from KSh 50,000 to KSh 400,000 Imagine Care Limited for commercial properties with serious termite risk. For residential homes, expect to pay between KSh 8,000 and KSh 30,000 for a full termite treatment depending on property size and infestation extent. This is not an area to cut corners on cost.

Rodent control Nairobi — KSh 4,000 to KSh 9,000

Rodent infestations — rats and mice — are common in older buildings, restaurants, warehouses, and properties near open drainage. Effective rodent control involves baiting, trapping, and importantly, identifying and sealing entry points. A company that only lays poison without sealing entry points will have you calling them back within weeks.

Mosquito fumigation Nairobi — KSh 3,000 to KSh 7,000

Mosquito treatments are especially important during Kenya’s long and short rainy seasons when breeding grounds multiply. A standard residential mosquito fumigation for a 3-bedroom house in Nairobi typically costs between KSh 3,000 and KSh 7,000. Outdoor areas — gardens, compounds, and drainage — must be treated alongside the interior for lasting results.

What does a professional fumigation actually include?

A reputable fumigation company in Nairobi will provide:

• A property inspection before quoting — not a blind flat-rate price over the phone
• A written quote specifying the pests targeted, chemicals to be used, and areas covered
• PCPB-approved, non-toxic insecticides that are safe for children, pets, and pregnant women
• A qualified, uniformed technician — not a casual worker with a borrowed sprayer
• Clear instructions on how long to vacate your property after treatment
• A service guarantee and a callback policy if pests return within the warranty period
• A completion certificate for commercial and rental properties

If a company cannot offer all of the above, the low price they quote is not worth the risk.

Red flags: How to avoid rogue fumigation companies in Nairobi

The Nairobi market has many unregistered operators who buy cheap pesticides from agro shops and offer rock-bottom prices. Here is what to watch out for:

No physical address or company registration — any legitimate pest control company in Kenya should be able to provide their business registration number and PCPB licensing details on request.

Unusually low quotes without a site visit — a professional company cannot accurately quote without assessing your property. An instant quote of KSh 1,500 for a full house fumigation should raise immediate concern.

No guarantee or callback policy — professional companies stand behind their work. If a company offers no warranty on re-infestation, they are not confident in what they are using.

Unknown chemicals — always ask for the specific product names and confirm they are registered with the Pest Control Products Board of Kenya. You have every right to this information before allowing any chemical to be used in your home.

How to get the best value from fumigation in Nairobi

Book a quarterly contract instead of a one-off treatment. Establishing a long-term relationship with your fumigation company and committing to ongoing service typically results in better pricing and more thorough protection. Businesslist.co.ke Annual or quarterly contracts also mean your property is protected year-round — not just reacting to an infestation after the fact.

Fumigate before moving into a new property. This is the single best time to fumigate — when rooms are empty, treatment is thorough, there are no furniture items to move, and you eliminate any existing pest population before it becomes your problem.

Bundle multiple services. If you need fumigation and a post-treatment deep clean, booking both with one company — like Imagine Care — is cheaper than hiring two separate providers, and it means the clean-up happens properly after the chemicals have done their work.

Book during off-peak periods. Demand for fumigation in Nairobi peaks during the rainy seasons (March–May and October–December). Booking in the dry months sometimes attracts lower pricing from companies managing their schedules.
