Complete Guide to Rodent Control & Prevention in Nairobi

Rats and mice are among the most damaging pests in Nairobi. They contaminate food, spread disease, gnaw through electrical wiring — a significant fire risk — and cause structural damage to buildings.

Common Rodent Species in Nairobi

• Black Rat / Roof Rat (Rattus rattus) — Agile climbers, often found in roof spaces and ceilings. The most common rodent pest in Nairobi residential properties.
• Brown Rat / Norway Rat (Rattus norvegicus) — Burrow underground near drains, basements, and foundations.
• House Mouse (Mus musculus) — Can squeeze through gaps as small as 6mm. Often found in kitchen plinths and behind appliances.

Signs of an Infestation

• Droppings along walls, behind appliances, or in kitchen cabinets
• Gnaw marks on food packaging, cables, and wooden structures
• Dark, greasy runways along walls where rodents travel regularly
• Scratching sounds in walls or ceilings, especially at night
• Burrow holes in gardens or under buildings

Kowa's Integrated Rodent Control Approach

1. Inspection — Identifying species, entry points, and extent of infestation
2. Baiting — Professional-grade rodenticide in tamper-proof bait stations along active runways
3. Trapping — Snap and electronic traps where baiting is not appropriate
4. Exclusion — Sealing entry points with steel wool, expanding foam, and metal plates
5. Follow-Up — Checking and replenishing bait stations; confirming population reduction

Prevention Tips

• Store all food in rodent-proof containers — plastic bags are not sufficient
• Seal gaps around pipes and cables with steel wool or metal plates
• Trim trees away from your building (roof rats use overhanging branches)
• Fix broken drainage and remove standing water
• Clear clutter from garages, roof spaces, and outbuildings
