Nairobi, Kenya’s bustling capital city, is home to millions of residents and visitors. While the city offers countless opportunities and a vibrant lifestyle, it also faces a persistent challenge that affects households, businesses, and public health: mosquito infestation. As we navigate through 2026, understanding the risks posed by mosquitoes and knowing how to control them has become more important than ever.
At Kitutoafrica Hygiene Solutions Company, we specialize in comprehensive mosquito control services across Nairobi and surrounding areas. With years of experience in pest management, we’ve seen firsthand how mosquito populations can grow rapidly when conditions are favorable, and we’re committed to helping Kenyans protect their homes, families, and businesses from these dangerous pests.
In this comprehensive guide, we’ll explore everything you need to know about mosquito infestation in Nairobi, from the health risks they pose to the most effective control methods available in 2026.
Understanding Mosquito Infestation in Nairobi
Nairobi’s unique climate and urban environment create ideal conditions for mosquito breeding. The city experiences two rainy seasons: the long rains from March to May and the short rains from October to December. During these periods, mosquito populations explode as standing water accumulates in various locations throughout the city.
However, mosquitoes are not just a seasonal problem in Nairobi. Even during dry months, poor drainage systems, water storage practices, and construction sites provide year-round breeding grounds. Areas like Eastlands, Kibera, Mathare, and even upmarket neighborhoods in Karen, Lavington, and Kilimani all experience mosquito problems, though the severity varies.
Why Mosquito Infestation is Increasing in Nairobi
Several factors contribute to the growing mosquito population in Nairobi:
Rapid urbanization has led to unplanned settlements where proper drainage is lacking. When rainwater collects in puddles, discarded containers, and blocked drainage systems, mosquitoes find perfect breeding spots.
Climate change is affecting rainfall patterns in Kenya. Unpredictable weather creates more standing water for longer periods, giving mosquitoes extended breeding seasons.
Poor waste management means that tires, plastic containers, bottles, and other items that collect water are scattered across neighborhoods, creating countless small breeding sites.
Water storage practices are common in Nairobi due to unreliable water supply. Many households store water in tanks, drums, and containers, which can become mosquito breeding grounds if not properly covered.
Construction activities throughout the city create temporary pools of water in excavations, building materials, and equipment, providing excellent mosquito habitats.
Health Risks of Mosquito Infestation
Mosquitoes are not just annoying pests that disrupt your sleep with their buzzing and itchy bites. They are among the deadliest creatures on Earth, responsible for transmitting diseases that kill hundreds of thousands of people globally each year. In Nairobi and across Kenya, mosquito-borne diseases pose a significant public health threat.
Malaria
Malaria remains one of Kenya’s most serious health challenges. While Nairobi is considered a low-risk area compared to regions near Lake Victoria or coastal areas, malaria cases still occur in the city, particularly in informal settlements and areas with poor drainage.
The disease is caused by parasites transmitted through the bites of infected female Anopheles mosquitoes. Symptoms include fever, chills, headaches, muscle aches, and fatigue. Without prompt treatment, malaria can become severe and even fatal, especially in children under five years old and pregnant women.
In 2026, despite ongoing control efforts, malaria continues to affect Kenyan communities. Climate change and increased rainfall patterns have expanded mosquito habitats, bringing the disease to areas previously considered safe.
Dengue Fever
Dengue fever is an emerging concern in Nairobi. This viral disease is transmitted by Aedes mosquitoes, particularly Aedes aegypti, which bite during the day. Cases of dengue have been reported in Kenya with increasing frequency over the past few years.
Symptoms of dengue include high fever, severe headache, pain behind the eyes, joint and muscle pain, and rash. In severe cases, dengue can lead to dengue hemorrhagic fever, which causes bleeding, blood plasma leakage, and can be fatal.
The Aedes mosquito thrives in urban environments, breeding in small water collections around homes, such as flower pots, water storage containers, and discarded items. This makes Nairobi’s residential areas particularly vulnerable.
Chikungunya
Chikungunya is another viral disease transmitted by Aedes mosquitoes. Like dengue, it has been detected in Kenya, including cases in Nairobi. The disease causes sudden onset of fever and severe joint pain that can last for weeks or even months.
Other symptoms include muscle pain, headache, nausea, fatigue, and rash. While chikungunya is rarely fatal, the prolonged joint pain can be debilitating and significantly impact quality of life and work productivity.
Zika Virus
Although less common in Kenya, Zika virus is present in Africa and transmitted by the same Aedes mosquitoes that carry dengue and chikungunya. The virus is particularly dangerous for pregnant women, as it can cause serious birth defects.
Most people infected with Zika virus experience mild symptoms or no symptoms at all, but the risk to unborn babies makes prevention crucial for expectant mothers in Nairobi.
Rift Valley Fever
Rift Valley Fever (RVF) is a viral disease that affects both animals and humans. In Kenya, outbreaks have occurred during periods of heavy rainfall. While primarily transmitted through contact with infected animals, mosquitoes also play a role in spreading the disease.
RVF can cause fever, weakness, back pain, and dizziness. In severe cases, it can lead to eye problems, brain inflammation, or hemorrhagic fever.
Other Health Impacts
Beyond specific diseases, mosquito bites can cause:
Allergic reactions ranging from mild swelling to severe responses requiring medical attention.
Secondary infections when scratched bites become infected with bacteria.
Sleep disruption leading to fatigue, reduced productivity, and decreased quality of life.
Anxiety and stress, particularly for parents worried about their children’s exposure to mosquito-borne diseases.
Common Mosquito Breeding Areas in Nairobi
Understanding where mosquitoes breed is essential for effective control. Female mosquitoes lay their eggs in or near water, and the larvae develop in aquatic environments. In Nairobi, mosquitoes find breeding sites in both obvious and unexpected places.
Around Your Home
Water storage containers are the number one breeding site in Nairobi homes. Uncovered water tanks, drums, buckets, and jerrycans provide ideal conditions for mosquito reproduction.
Flower pots and plant saucers collect water and are often overlooked during cleaning routines.
Blocked gutters filled with leaves and debris create stagnant water pools along rooflines.
Old tires stored in yards or used as planters retain water in their curved surfaces.
Discarded containers such as bottles, cans, cups, and food containers scattered in compounds collect rainwater.
Pet water bowls left unchanged for several days can produce mosquitoes.
Air conditioner drip trays and refrigerator drip pans that collect condensation.
Septic tanks and soak pits with cracks or unsealed openings.
In Your Neighborhood
Open drains and trenches with stagnant water are common in many Nairobi estates.
Construction sites with excavations, cement mixers, and building materials that collect water.
Dumping sites filled with containers and waste that trap rainwater.
Abandoned swimming pools or poorly maintained pools in residential compounds.
Vehicle washing bays where water accumulates in depressions.
Public water points with spillage and puddles around taps.
Overgrown vegetation near water sources that provides shelter for adult mosquitoes.
Natural Breeding Sites
Rivers and streams flowing through Nairobi, including the Nairobi River, Ngong River, and their tributaries, especially in slow-moving or polluted sections.
Wetlands and swamps in areas like Korogocho, Dandora, and near Jomo Kenyatta International Airport.
Ponds and dams in recreational parks and private properties.
Natural depressions that collect rainwater in open fields and vacant lots.
Professional Mosquito Control Methods in 2026
At Kitutoafrica Hygiene Solutions Company, we use the most advanced and effective mosquito control methods available in 2026. Our approach combines multiple strategies to provide comprehensive protection for homes and businesses across Nairobi.
Integrated Pest Management (IPM)
We follow an Integrated Pest Management approach that combines different control methods for maximum effectiveness while minimizing environmental impact. This strategy includes inspection, source reduction, biological control, chemical control, and ongoing monitoring.
Inspection and Assessment
Every mosquito control program begins with a thorough inspection of your property. Our trained technicians identify:
- Current mosquito breeding sites
- Potential future breeding areas
- Entry points into buildings
- Areas of high mosquito activity
- Environmental factors contributing to infestation
This assessment allows us to create a customized control plan tailored to your specific situation.
Source Reduction
The most effective mosquito control strategy is eliminating breeding sites. Our team works with you to:
- Identify and remove or drain containers holding standing water
- Repair leaking pipes and taps
- Improve drainage around your property
- Seal septic tanks and soak pits
- Clean gutters and downspouts
- Cover water storage containers with tight-fitting lids or mosquito-proof screens
Larviciding
For water sources that cannot be eliminated, we apply larvicides to kill mosquito larvae before they become biting adults. We use:
Biological larvicides containing bacteria (Bacillus thuringiensis israelensis or Bacillus sphaericus) that specifically target mosquito larvae without harming other organisms.
Insect Growth Regulators (IGRs) that prevent larvae from developing into adults.
Larvicidal oils that form a film on water surfaces, suffocating larvae.
These treatments are safe for use around humans and pets when applied by trained professionals.
Adult Mosquito Control
To quickly reduce the number of biting mosquitoes, we employ several methods:
Residual spraying involves applying long-lasting insecticides to walls, ceilings, and other surfaces where mosquitoes rest. This creates a barrier that kills mosquitoes on contact and provides protection for weeks or months.
Space spraying (fogging) uses specialized equipment to disperse insecticide as a fine mist that kills adult mosquitoes in the air. This is particularly effective for outdoor events or severe infestations.
Ultra-Low Volume (ULV) applications deliver precise amounts of insecticide in extremely small droplets, maximizing effectiveness while minimizing chemical use.
Biological Control
We utilize nature’s own mosquito enemies:
Mosquito fish (Gambusia) can be introduced to ornamental ponds and water features to eat mosquito larvae.
Bacterial agents that specifically target mosquito larvae without affecting other aquatic life.
Mosquito Traps and Monitoring
Advanced mosquito traps help us:
- Monitor mosquito populations on your property
- Identify the specific mosquito species present
- Reduce adult mosquito numbers through targeted trapping
- Assess the effectiveness of our control measures
Barrier Treatments
For homes and businesses with outdoor areas, we create protective barriers by treating vegetation, fences, and structures where mosquitoes rest during the day. These treatments significantly reduce mosquito populations in yards, gardens, and outdoor entertainment areas.
Seasonal Programs
Recognizing that mosquito pressure varies throughout the year, we offer seasonal programs that intensify during peak breeding seasons (March-May and October-December) and maintain protection during drier months.
DIY Mosquito Prevention Tips for Nairobi Residents
While professional mosquito control is the most effective solution for serious infestations, there are many steps you can take to reduce mosquito populations around your home:
Eliminate Standing Water
- Empty flower pots, buckets, and containers at least once a week
- Cover all water storage containers with tight-fitting lids or fine mesh
- Change water in pet bowls and bird baths every two to three days
- Ensure swimming pools are properly chlorinated and filtered
- Fill in puddles and depressions in your yard
- Dispose of old tires or store them in covered areas
Maintain Your Property
- Clean gutters regularly to prevent water accumulation
- Repair leaking outdoor taps and pipes immediately
- Trim overgrown vegetation where mosquitoes rest
- Ensure proper drainage around your compound
- Keep your yard free of trash and discarded containers
Protect Your Home
- Install mosquito screens on windows and doors
- Repair any holes or tears in existing screens
- Use door sweeps to seal gaps under doors
- Keep doors and windows closed during peak mosquito hours (dawn and dusk)
- Use mosquito nets over beds, especially for children and pregnant women
Use Mosquito Repellents
- Apply EPA-approved insect repellents containing DEET, picaridin, or oil of lemon eucalyptus when outdoors
- Use mosquito coils or electric mosquito repellent devices indoors
- Wear long-sleeved shirts and long pants during high mosquito activity times
- Choose light-colored clothing, as mosquitoes are attracted to dark colors
Community Action
Mosquito control is most effective when entire communities participate:
