Most Common Types of Pests in Nairobi

Nairobi’s warm climate and rapid urbanization create ideal conditions for various pests to thrive. Whether you live in upscale neighborhoods like Karen and Westlands or bustling areas like Eastlands, pest infestations can affect any home or business. Understanding the most common pests in Nairobi is the first step toward effective prevention and control.

Cockroaches

Cockroaches top the list of pest complaints in Nairobi households and commercial establishments. The German cockroach and American cockroach are particularly prevalent in the city. These resilient insects thrive in warm, humid environments, making Nairobi kitchens, bathrooms, and drainage systems their preferred habitats.

Cockroaches are not just unsightly; they carry diseases including salmonella, typhoid fever, and gastroenteritis. They contaminate food surfaces and trigger allergies and asthma, especially in children. These nocturnal pests multiply rapidly, with a single female producing hundreds of offspring in her lifetime.

Rodents (Rats and Mice)

Rats and mice pose significant health and property risks across Nairobi. The brown rat, black rat, and house mouse are common culprits in both residential and commercial properties. These rodents are attracted to areas with poor waste management, which unfortunately characterizes many neighborhoods in the city.

Beyond the obvious hygiene concerns, rodents gnaw through electrical wiring, causing fire hazards, and damage property including furniture, walls, and stored goods. They spread serious diseases such as leptospirosis, hantavirus, and plague through their droppings, urine, and bites.

Bedbugs

Bedbugs have become increasingly problematic in Nairobi, affecting hotels, residential apartments, and even upscale homes. These tiny blood-sucking insects hide in mattress seams, bed frames, furniture cracks, and wall crevices, making them difficult to detect until an infestation becomes severe.

Bedbug bites cause itchy welts, skin infections from scratching, and significant psychological distress. The stigma associated with bedbugs and the difficulty of elimination make them one of the most dreaded pests in the city.

Mosquitoes

Nairobi’s altitude traditionally protected it from malaria-carrying mosquitoes, but climate change and urban expansion have altered this reality. Mosquitoes now breed in stagnant water found in poorly maintained drainage systems, old tires, flower pots, and water storage containers common in areas with inconsistent water supply.

Beyond malaria, mosquitoes transmit dengue fever, chikungunya, and Zika virus. Their constant buzzing and itchy bites disrupt sleep and outdoor activities, particularly during the rainy seasons when populations explode.

Termites

Termites cause extensive structural damage to buildings throughout Nairobi, often going unnoticed until significant harm has occurred. The subterranean termite is especially destructive, attacking wooden structures, furniture, books, and even crops in urban farming areas.

The warm, humid conditions during rainy seasons accelerate termite activity. Properties in areas like Karen, Runda, and other neighborhoods with older wooden structures face particular vulnerability. Annual termite damage costs Nairobi property owners millions of shillings in repairs and preventive treatments.

Flies

House flies, fruit flies, and drain flies are constant nuisances in Nairobi homes and food establishments. These pests breed in garbage, sewage, and decaying organic matter, which are abundant in areas with inadequate waste collection services.

Flies contaminate food by transferring pathogens from filth to eating surfaces, spreading diseases like cholera, dysentery, and typhoid. Their presence in restaurants and food processing facilities poses serious health code violations and reputation risks.

Ants

Various ant species including black ants, red ants, and carpenter ants infest Nairobi properties. While less dangerous than other pests, ants contaminate food, create unsightly trails through homes, and can cause painful bites. Carpenter ants specifically damage wooden structures by excavating galleries for their nests.

Professional Pest Control is Essential

Given Nairobi’s favorable conditions for pest proliferation, professional pest control services are not a luxury but a necessity. Regular inspections, preventive treatments, and immediate response to infestations protect health, property, and peace of mind. Combining professional services with good sanitation practices, proper waste management, and structural maintenance provides the best defense against Nairobi’s persistent pest problems.
