Living in Nairobi comes with many advantages, but one unwelcome challenge that many homeowners and business owners face is rodent infestation. Rats and mice are more than just a nuisance; they pose serious health risks, cause property damage, and can harm your reputation if you run a business.
At Kitutoafrica Hygiene Solutions Company, we’ve been helping Nairobi residents and businesses tackle rodent problems for years. In this comprehensive guide, we’ll walk you through everything you need to know about rodent infestation in 2026, from identifying the early warning signs to understanding the dangers and implementing proven control methods.
Understanding Rodent Infestation in Nairobi
Nairobi’s warm climate, rapid urbanization, and abundant food sources create the perfect environment for rodents to thrive. The most common rodents found in Kenyan homes and businesses are the Norway rat (brown rat), roof rat (black rat), and the house mouse.
These pests are incredibly adaptable creatures. They can squeeze through openings as small as a coin, climb walls, swim through sewer pipes, and survive on minimal food and water. This makes them particularly challenging to control once they’ve established themselves in your property.
Why Are Rodent Infestations Increasing in Nairobi?
Several factors contribute to the growing rodent problem in Nairobi:
Rapid urbanization: As Nairobi continues to expand, construction activities disturb rodent habitats, forcing them to seek shelter in homes and commercial buildings. Areas like Westlands, Kilimani, Parklands, and Eastlands have seen significant development, which often displaces rodents into residential areas.
Poor waste management: Inadequate garbage disposal in some neighborhoods provides rodents with abundant food sources. Open dumpsters, uncollected waste, and improper food storage attract rats and mice from surrounding areas.
Climate conditions: Nairobi’s moderate temperatures allow rodents to breed year-round, unlike colder climates where their reproduction slows during winter. The rainy seasons (March-May and October-December) often drive rodents indoors seeking dry shelter.
Aging infrastructure: Older buildings in areas like the CBD, South B, and South C often have cracks, gaps, and deteriorating structures that provide easy entry points for rodents.
Early Warning Signs of Rodent Infestation
Catching a rodent problem early can save you thousands of shillings in damage and health costs. Here are the telltale signs that you have unwanted guests:
1. Droppings and Urine Stains
Rodent droppings are one of the most obvious signs of infestation. Rat droppings are typically dark brown or black, about 12-18mm long, and shaped like large grains of rice. Mouse droppings are smaller, about 3-8mm long, and more pointed at the ends.
You’ll typically find droppings along walls, in cupboards, under sinks, in attics, and near food storage areas. Fresh droppings are dark and moist, while old ones are dry and crumbly. If you’re finding fresh droppings regularly, you have an active infestation.
Urine stains appear as small streaks or pools, often with a strong ammonia-like smell. Rodent urine glows under ultraviolet (UV) light, which professionals use to detect the extent of infestation.
2. Gnaw Marks and Damage
Rodents must constantly gnaw to keep their teeth from growing too long. You might notice gnaw marks on:
- Wooden furniture and door frames
- Electrical wires and cables
- Food packaging and containers
- Plastic pipes and PVC materials
- Books, papers, and cardboard boxes
Fresh gnaw marks appear lighter in color and become darker as they age. If you’re seeing light-colored gnaw marks, the infestation is current and active.
3. Scratching and Scurrying Noises
Rodents are most active at night. If you hear scratching sounds in your ceiling, walls, or under floors during evening hours, you likely have rodents. The sounds might include:
- Scratching or scampering in the ceiling
- Squeaking or chattering noises
- Gnawing sounds inside walls
- Running sounds in the attic or roof space
These noises are particularly common in the early morning hours (between 2 AM and 5 AM) when rodents are most active.
4. Grease Marks and Runways
Rats have poor eyesight and navigate by following the same paths repeatedly. Over time, they leave dark grease marks along walls, baseboards, and beams from the oils in their fur rubbing against surfaces.
You might notice these greasy smudge marks along walls at floor level, especially in corners and along regular pathways. These marks indicate frequently used rodent highways in your property.
5. Nests and Nesting Materials
Rodents build nests using shredded paper, fabric, insulation material, dried plants, and other soft materials. Common nesting locations include:
- Behind appliances (refrigerators, stoves, washing machines)
- In attic spaces and roof cavities
- Inside wall voids and cupboards
- Under floorboards
- In storage boxes and unused furniture
If you find a nest, there’s a breeding population in your property, which requires immediate professional intervention.
6. Unusual Pet Behavior
Your cats or dogs might become unusually interested in specific areas of your home, pawing at walls, staring at cupboards, or becoming agitated in certain rooms. Pets can hear and smell rodents that humans might miss.
7. Actual Rodent Sightings
Seeing a rodent during daylight hours is a serious sign. Rodents are nocturnal and avoid humans, so daytime sightings typically indicate a large population where competition for food forces some individuals to forage during the day.
Serious Health Dangers of Rodent Infestation
Rodents are not just annoying; they’re dangerous. They pose significant health risks to you, your family, your employees, and your customers.
Diseases Transmitted by Rodents
Rodents can carry and transmit over 35 diseases to humans. Here are the most concerning ones in Kenya:
Leptospirosis: This bacterial disease spreads through contact with water, soil, or food contaminated with urine from infected rodents. Symptoms include high fever, headache, muscle aches, and can lead to kidney damage, liver failure, or even death if untreated. Leptospirosis cases have been reported in Nairobi, particularly during rainy seasons.
Salmonellosis: Rodents spread Salmonella bacteria through their droppings, which can contaminate food preparation surfaces and stored food. This causes food poisoning with symptoms including diarrhea, fever, and abdominal cramps.
Hantavirus: Though less common in Kenya, this virus can be transmitted through inhalation of dust contaminated with rodent urine or droppings. It can cause Hantavirus Pulmonary Syndrome, a severe respiratory disease.
Rat-bite fever: This bacterial illness spreads through bites or scratches from infected rodents, or by consuming food or water contaminated with rat feces. Symptoms include fever, vomiting, headaches, and muscle pain.
Plague: While rare in modern Kenya, plague-causing bacteria can still be carried by rodent fleas. Outbreaks have occurred in rural areas, making rodent control crucial for public health.
Typhus: Fleas that live on rats can transmit typhus to humans, causing fever, headache, and rash.
Contamination of Food and Surfaces
A single mouse can produce up to 75 droppings per day, while rats can produce up to 40. These droppings, along with urine and hair, contaminate food storage areas, kitchen surfaces, and eating areas.
Rodents often travel through sewers and garbage before entering your home or restaurant, bringing harmful bacteria on their feet and fur. This cross-contamination is particularly dangerous in food businesses, hotels, restaurants, and hospitals.
Allergies and Asthma
Rodent droppings, urine, and dander can trigger allergic reactions and asthma attacks, especially in children. Studies show that exposure to rodent allergens in childhood increases the risk of developing asthma and other respiratory conditions.
Parasites
Rodents host various parasites including fleas, ticks, and mites, which can spread to humans and pets. These parasites carry their own set of diseases and can cause skin irritation and other health problems.
Property Damage and Economic Impact
Beyond health risks, rodents cause significant property damage:
Structural Damage
Rodents gnaw through wood, plaster, and soft concrete, weakening building structures. They can damage:
- Foundation materials
- Wall insulation
- Roof structures
- Water pipes, causing leaks and water damage
- Support beams and joists
This damage can cost hundreds of thousands of shillings to repair and may compromise the structural integrity of your building.
Electrical Hazards
One of the most dangerous aspects of rodent infestation is damage to electrical wiring. Rodents gnaw through wire insulation, which can cause:
- Short circuits
- Power outages
- Electrical fires
- Damage to appliances and electronics
The National Fire Protection Association estimates that rodents cause thousands of electrical fires annually worldwide. In Kenya, many unexplained electrical fires are later attributed to rodent damage.
Business Impact
For businesses, rodent infestation can result in:
- Failed health inspections
- Temporary or permanent closure orders
- Loss of business licenses
- Damaged reputation and lost customers
- Contaminated inventory that must be destroyed
- Legal liability if customers become ill
A single rodent sighting posted on social media can destroy a restaurant’s reputation overnight in our connected world of 2026.
Proven Rodent Control Methods in 2026
At Kitutoafrica Hygiene Solutions Company, we use integrated pest management (IPM) approaches that combine multiple strategies for maximum effectiveness.
Professional Inspection and Assessment
The first step in any effective rodent control program is a thorough professional inspection. Our trained technicians:
- Identify the rodent species present
- Locate entry points and access routes
- Determine the extent of infestation
- Identify food sources and attractants
- Assess conducive conditions
- Develop a customized treatment plan
This comprehensive assessment ensures we address the root causes, not just the symptoms.
Exclusion and Proofing
Exclusion means sealing entry points to prevent rodents from entering your property. This is the most effective long-term solution. Our exclusion services include:
Sealing gaps and cracks: We use steel wool, copper mesh, and cement to seal openings larger than 6mm (the size a mouse can squeeze through). Common entry points include gaps around pipes, vents, doors, windows, and utility lines.
Installing door sweeps: Gaps under doors are highway entrances for rodents. We install proper door sweeps and threshold seals.
Repairing screens: Damaged window screens and roof vents are repaired or replaced with rodent-proof materials.
Covering vents: Air vents are covered with fine mesh screens that allow airflow while blocking rodent entry.
Tree trimming: We recommend trimming tree branches that touch your roof or walls, as these provide rodent highways into upper floors.
Trapping Programs
Trapping is a non-toxic method that’s particularly effective for light to moderate infestations. We use:
Snap traps: Traditional and effective for quick kills. We strategically place them along rodent runways and near active signs.
Live catch traps: These capture rodents alive for removal, useful in sensitive areas where dead rodents might create odor problems.
Multi-catch traps: These capture multiple mice in a single device, ideal for high-activity areas.
Glue boards: Adhesive traps work well for monitoring and in areas where snap traps aren’t suitable, though we use these selectively due to humane concerns.
Our technicians place traps strategically based on rodent behavior patterns and check them regularly to ensure effectiveness and maintain hygiene.
Rodenticide Application (When Necessary)
In severe infestations, we may use rodenticides as part of a comprehensive control program. We only use registered products approved by the Pest Control Products Board of Kenya, and application is done by licensed professionals following strict safety protocols.
We use:
Anticoagulant baits: These interfere with blood clotting and are effective against rodents that have developed resistance to older products.
Tamper-resistant bait stations: All rodenticides are placed in locked, child-resistant stations that prevent access by children, pets, and non-target animals.
Tracking powder: In some situations, we use tracking powders that rodents pick up on their fur and ingest during grooming.
Our technicians carefully document all rodenticide placements and monitor them regularly to prevent secondary poisoning and ensure effectiveness.
Sanitation and Habitat Modification
Controlling food, water, and shelter is crucial for long-term rodent management:
Food source elimination: We help you identify and eliminate food sources by recommending proper food storage in sealed, rodent-proof containers, regular garbage disposal in covered bins, cleaning up food spills immediately, and removing pet food bowls overnight.
Water source control: Fixing leaking pipes and taps, ensuring proper drainage, removing standing water, and keeping areas dry reduces rodent attraction.
Clutter reduction: Rodents love cluttered areas that provide hiding spots. We recommend organizing storage areas, elevating stored items off the floor, using sealed plastic containers instead of cardboard boxes, and maintaining clear spaces along walls.
Landscaping management: Keeping grass trimmed, removing dense vegetation near buildings, storing firewood away from structures, and eliminating outdoor debris reduces rodent harborage.
Monitoring and Maintenance
Rodent control isn’t a one-time fix. At Kitutoafrica Hygiene Solutions Company, we offer ongoing monitoring programs that include:
- Regular inspections to detect new activity early
- Maintenance of exclusion measures
- Trap checking and repositioning
- Bait station servicing
- Documentation and reporting
- Adjustment of strategies based on results
Our maintenance programs are customized to your specific needs and risk level, with monthly, bi-monthly, or quarterly service options.
Modern Technology in Rodent Control
In 2026, rodent control has become more sophisticated with new technologies:
Electronic Monitoring Systems
We use smart sensors and traps that send real-time alerts when rodents are detected or caught. This allows for immediate response and provides valuable data on rodent activity patterns.
Ultrasonic Devices
While controversial and not a standalone solution, ultrasonic repellents can be part of an integrated approach in certain situations. We evaluate whether these are appropriate for your specific circumstances.
Thermal Imaging
We use thermal cameras to detect rodent activity in walls and ceilings without destructive investigation, allowing us to locate nests and runways precisely.
Data Analytics
Our monitoring programs collect data over time, allowing us to identify patterns, predict high-risk periods, and continuously improve our control strategies for your property.
DIY Prevention Tips for Nairobi Residents
While professional service is essential for active infestations, here are steps you can take to prevent rodent problems:
In Your Home
- Store food properly: Keep all food in sealed glass or metal containers. Don’t leave pet food out overnight.
- Maintain cleanliness: Clean up spills immediately, wash dishes promptly, and don’t leave food waste in open bins.
- Dispose of garbage regularly: Use bins with tight-fitting lids and take out garbage frequently.
- Eliminate water sources: Fix all leaks promptly and wipe down sinks before bed.
- Seal entry points: Check your property monthly for new gaps and seal them immediately.
- Declutter regularly: Keep storage areas organized and use sealed containers.
- Inspect packages: Check grocery bags and delivery boxes for rodent signs before bringing them inside.
For Business Owners

Choosing the Right Rodent Control Company in Nairobi
Not all pest control services are equal. Here’s what to look for:
Licensing and Certification
Ensure the company is registered with the Pest Control Products Board (PCPB) of Kenya and employs certified pest control operators. At Kitutoafrica Hygiene Solutions Company, all our technicians are fully licensed and regularly trained on the latest control methods.
Experience and Expertise

Customized Solutions
Avoid companies that offer one-size-fits-all solutions. Every property is unique and requires a tailored approach based on thorough inspection and assessment.
Transparent Pricing
Reputable companies provide clear, written quotes with no hidden fees. Be wary of extremely cheap services, as they often cut corners on materials, expertise, or thoroughness.
Guarantees and Follow-up
Quality pest control companies stand behind their work with service guarantees and include follow-up visits to ensure effectiveness.
Customer Reviews and References
Check online reviews, ask for references, and verify the company’s reputation before signing a contract.

Common Myths About Rodent Control
Let’s address some misconceptions:
Myth 1: “Cats are effective rodent control.” While cats may catch occasional mice, they’re not reliable for controlling infestations. Professional control is still necessary.
Myth 2: “If I don’t see rodents, I don’t have a problem.” Rodents are nocturnal and avoid humans. You might have a significant infestation without ever seeing a live rodent.
Myth 3: “Cheese is the best bait.” Rodents actually prefer foods high in sugar, protein, or fat. Peanut butter, chocolate, and nuts work better than cheese.
Myth 4: “Ultrasonic repellents solve the problem.” Research shows limited effectiveness for ultrasonic devices. They may cause temporary disturbance but won’t eliminate infestations.
Myth 5: “Once treated, rodents won’t come back.” Without proper exclusion and maintenance, new rodents will eventually find their way in. Ongoing prevention is essential.
