Mosquitoes and Midges

Everyone knows how annoying and painful midge and mosquito bites can be. In Kenya, these pests are more than just a nuisance; they pose a significant health risk, transmitting diseases like Malaria, Dengue, Chikungunya, and Rift Valley Fever.

Understanding the specific biting insect species found in our region is the first step toward effective prevention. Rentokil Kenya provides expert, targeted solutions to eliminate breeding sites and protect your family or business from these dangerous biting insects.

Here are some facts that you might want to know about these nasty little insects:

  • They can develop from eggs to adults in just six to ten days.
  • They are found close to still-standing water, where their larvae feed and develop.
  • They seem to be attracted to bright colours.
  • Mosquitoes will normally bite you at dawn or dusk, or if you’re unlucky, both. That’s when their internal clocks tell them that it is feeding time.

We’ll arrange a visit from one of our expert technicians to assess the midge or mosquito control problem and recommend a way to get them to buzz off.

Rapid Lifecycle: They develop from eggs to adults in just six to ten days, meaning a small problem can quickly become an infestation

The Mosquito Threat in Kenya: Fast Facts

  • Disease Vectors: - Mosquitoes in Kenya are responsible for spreading serious diseases, with Malaria being the most prevalent.

  • Rapid Lifecycle: - They develop from eggs to adults in just six to ten days, meaning a small problem can quickly become an infestation.

  • Breeding Sites: - They are found close to any source of still-standing water from puddles to uncovered water tanks where their larvae feed and develop.

  • Biting Times: - Mosquitoes are most active and likely to bite at dawn or dusk, when their internal clocks signal feeding time.

Targeted Identification and Elimination

Our technicians are experts in pest behaviour. They can provide the best, most localized treatment for your specific problem, including:

  • Source Reduction: - Identifying and treating or eliminating standing water breeding sites.

  • Larviciding: - Applying approved treatments to water bodies to stop mosquitoes before they hatch.

  • Residual Spraying - Applying effective, long-lasting insecticides to resting surfaces (like walls and vegetation) to control adult mosquitoes.

1. Eliminate Standing Water

This is the single most crucial step to stop mosquitoes from breeding. Mosquitoes lay their eggs in stagnant water.

  • Action: Regularly empty, clean, or discard any containers that collect water, such as flowerpots, old tires, buckets, and clogged gutters. Change the water in pet dishes and bird baths frequently.

2. Install and Maintain Screens and Nets

Physical barriers are highly effective at preventing mosquitoes from entering your home.

  • Action: Fit fly screens to all windows and doors. Ensure they are well-maintained, free of tears or holes, and used correctly, especially during peak biting hours. Sleep under a mosquito net if screens are not available or damaged.

3. Use Effective Repellents

When you are outdoors, repellents provide a necessary layer of personal protection.

  • Action: Apply an effective, approved insect repellent to exposed skin and/or clothing. Look for products containing ingredients like DEET, Picaridin, or Oil of Lemon Eucalyptus (OLE). Apply just before going outdoors, particularly around dawn and dusk.

4. Cover and Secure Water Storage

Any essential water storage must be properly sealed to prevent access.

  • Action: Ensure all water storage containers, such as water butts, tanks, and drums, have well-fitted, tight lids. This prevents adult female mosquitoes from accessing the water to lay their eggs.

How to Avoid Mosquito Bites

There is a greater risk of mosquito bites when you are outdoors and from dusk into night as this is when many biting insects are most active.

Luckily, there are ways you can keep safe when you are out and about:

Reduce Exposed Skin

Wear long sleeves, trousers, footwear and hats, especially during peak biting times.

Use insect repellent sprays

Apply to exposed skin and use repelling products or candles when sitting outdoors.

Avoid bright colours

Do not wear bright colours or use strong scents such as perfumes and deodorants as these attract insects.

Avoid areas with water

Keep clear of slow-moving, still, or stagnant water (like ditches, ponds, or swamps), as these are common mosquito breeding sites.

Tuck trousers into socks

 When hiking through brush or rough grass and avoid brushing through long grass or bushes.

Limit Outdoor Activity

 If possible, limit your time outdoors between dusk and dawn, as this is when many mosquito species are most active and feeding.

Treatments for Mosquito Bites

Mosquito bites are not usually painful, but the itchiness that follows a bite can cause some discomfort.


In Kenya, it is important to remember the health risks associated with mosquito and midge bites, as they can transmit serious diseases like Malaria, Dengue, and Chikungunya.


Reaction to mosquito bites will vary from person to person. Symptoms that develop are just our immune system’s response to their saliva.

Mosquito Management for Businesses and Homes

We train our technicians in identification, mosquito behaviour, monitoring and control, so that they use the most efficient and appropriate control methods for each situation.

Frequently Asked Questions about Mosquitoes and Midges in Kenya


  • What serious diseases do mosquitoes transmit in Kenya?

    Mosquitoes in Kenya are known carriers of Malaria, Dengue, and Chikungunya viruses. Professional control is essential for public health safety.


  • How can Rentokil eliminate mosquito breeding sites?

    Our service includes a detailed survey to locate and treat breeding sites, often using larvicides in non-potable standing water to stop the lifecycle before mosquitoes mature.


  • What is the difference between adulticiding and larviciding?

    Larviciding targets the immature mosquito stage in the water. Adulticiding involves the targeted application of insecticides to control adult mosquitoes resting on surfaces (residual spraying) or flying (fogging).


  • Can professional mosquito control be done for large commercial properties or estates?

    Yes. We provide customized pest management plans for large-scale operations like hotels, resorts, industrial sites, and residential estates, focusing on sustained reduction of the mosquito population.
