Professional Cockroach Control Services in Kenya
German and American cockroaches spread 33+ types of bacteria across Kenyan kitchens, restaurants, and food storage facilities every night. They contaminate food, trigger asthma attacks, and are increasingly resistant to over-the-counter sprays.
Our colony-elimination approach uses professional gel baiting, residual insecticides, and targeted crack-and-crevice treatments to wipe out entire populations — not just the few you can see.

Why Cockroaches Are a Serious Public Health Hazard
Cockroaches are not merely a nuisance — they are vectors for serious disease. A single cockroach foraging through sewage and then across your kitchen worktop can deposit hundreds of pathogenic bacteria. In Kenyan urban environments, the consequences are severe. Pestraid Kenya's cockroach control service provides detailed information on the health risks and professional treatment options available.
Cockroach infestations have been directly linked to repeated disease outbreaks in Nairobi's food service industry, shared residences, and schools. Controlling them is a public health obligation, not just a comfort matter. Kitchens with cockroach problems frequently also struggle with houseflies — Pestraid Kenya's housefly control service is a recommended addition for commercial food handling environments.
Our 6-Step Cockroach Elimination Process
Effective cockroach control requires a systematic, multi-method approach. Surface sprays alone never achieve lasting control — here's how we do it properly. Compare this process with the approach at Pestraid Kenya's professional cockroach elimination service.
Full Property Inspection
We conduct a systematic inspection of all cockroach harborage zones — kitchen units, plumbing voids, electrical panels, appliance motors, drains, and storerooms. We identify the species (German or American), map infestation hotspots, and document entry points.
Gel Bait Application
Gel bait is placed in precise micro-dots at cockroach activity points. Cockroaches are attracted to the bait, consume it, return to the harbourage, and die — where other cockroaches then consume the contaminated bodies, creating a lethal cascade through the population.
Residual Insecticide Treatment
We apply long-lasting residual insecticides to all surface areas where cockroaches travel, including skirting boards, behind appliances, shelf undersides, and drainage channels. The residual effect continues killing cockroaches for weeks after application.
Crack and Crevice Treatment
Targeted application of insecticide dust or gel into wall cracks, junction gaps, and structural voids where cockroaches shelter. This reaches populations that surface treatments cannot access.
Drain and Sewer Treatment
German cockroaches exploit drainage systems as highways between properties. We treat drains and sewer access points with appropriate insecticide formulations to break this transmission route.
Follow-Up Inspection
We return 2–3 weeks post-treatment to assess efficacy, address any residual activity, and provide recommendations for structural proofing to prevent re-infestation.
Preventing Cockroach Re-Infestation
Treatment eliminates your current infestation. These structural and hygiene measures prevent cockroaches from returning. For spider pest problems that sometimes share harborage zones with cockroaches, Pestraid Kenya's spider control service covers treatment across all major Kenyan cities.

Frequently Asked Questions
What is the difference between German and American cockroaches?
German cockroaches (small, tan) are the most common kitchen pest — they breed rapidly and are highly resistant to many pesticides. American cockroaches (large, reddish-brown) typically enter from drains and sewers. Treatment methods differ between species, which is why professional identification at inspection is essential.
How quickly will I see results after treatment?
Gel bait results are typically visible within 3–5 days as cockroach activity increases before collapsing. Full population elimination usually occurs within 2–4 weeks depending on infestation severity.
How many treatments will I need?
Most infestations are resolved in 1–2 treatments. Severe or long-standing commercial infestations may require an ongoing monthly programme. We'll advise the appropriate schedule at your free inspection.
Is cockroach treatment safe for food preparation areas?
Yes. Our gel bait formulations are approved for use in food handling environments. We apply treatments carefully to avoid food contact surfaces and provide clear guidance on when surfaces can be used again.
Why do cockroaches keep coming back?
Re-infestation typically occurs through untreated entry points such as drain pipes, service ducts, and structural gaps. Long-term control requires both chemical treatment and structural proofing — we provide detailed recommendations for both.
