Description
In Kenya, fogging machines are used for mosquito control, selected agricultural pest management operations and specialised sanitation work. They are available in petrol-powered thermal models and electric cold fogging models.
The right machine depends on the treatment area, chemical formulation, required droplet size, power source and operator’s experience.
Types of Fogging Machines Available in Kenya
1. Thermal Fogging Machine
Uses heat from a fuel-powered system to produce a fine fog. Commonly selected for professional outdoor mosquito control and suitable large-area treatments.
2. Electric ULV Cold Fogging Machine
Uses airflow rather than heat to atomise liquid. Often used in controlled indoor applications when both the machine and chemical are approved for the intended purpose.
3. Vehicle-Mounted Fogging Machine
A larger system used by professional teams for planned area-wide mosquito control programmes.
Thermal and cold fogging are different application methods. Thermal machines use heat to form fog, while cold foggers use mechanical atomisation. The World Health Organization provides separate technical guidance for selecting pesticide application equipment.

How a Fogging Machine Works
A fogging machine disperses a liquid formulation into small droplets that travel through the air.
In a thermal fogger, the machine uses heat to vaporise or atomise a suitable formulation. As the vapour meets cooler air, it forms a visible fog.
In a cold fogger, a motor or airflow system creates droplets without heating the liquid.
The droplet size, application rate and chemical formulation determine how the machine should be used. Producing a thick cloud does not automatically mean better pest control.
WHO guidance notes that thermal fog droplets are generally very small, often below 15 microns, while suitable droplet sizes for ULV mosquito control depend on the application.
Main Features of a Professional Fogging Machine
1. Fine Fog Production
A fogging machine produces small droplets that can be carried through the treatment area.
This is useful for professional mosquito control when the approved insecticide, droplet size and application conditions are correct.
2. Large Chemical Tank
Some portable thermal foggers sold in Kenya have chemical tanks holding up to 15 or 16 litres.
A larger tank can reduce the number of refilling stops during lengthy treatments.
However, tank capacity also affects the weight of the machine when full.
3. Petrol-Powered Operation
Petrol thermal foggers can operate without a continuous mains electricity connection.
This makes them useful for suitable outdoor operations in farms, estates and other locations where electrical power is unavailable.
The correct fuel type and mixture must come from the manufacturer’s instructions. Different models have different fuel requirements.
4. Stainless Steel Construction
Many thermal foggers use stainless steel components in their combustion and fogging systems.
These components are designed to withstand the operating conditions of the machine.
Users should still protect the machine from corrosion, impact and improper chemical handling.
5. Portable Design
Portable foggers may have carrying handles or shoulder straps.
This allows trained operators to move between designated treatment locations.
The machine should not be carried or operated in a way that exposes the operator or other people to hot exhaust components.
6. Electric Starting System
Some thermal foggers feature rechargeable battery ignition.
This can make starting the machine more convenient than models that rely on manual starting methods.
Check whether the battery, charger and starting accessories are included.
Uses of Fogging Machines in Kenya

Mosquito Control
Fogging machines are often used to apply insecticides targeting adult mosquitoes.
However, fogging alone does not provide long-term mosquito prevention.
The CDC notes that fogging has limited effectiveness as a routine malaria control measure in endemic areas and is mainly reserved for specific emergency or outbreak situations.
Removing stagnant water, managing mosquito breeding sites and using other proven prevention measures remain important.
Hotels and Commercial Properties
Professional pest control companies may use fogging equipment during approved treatment programmes at hotels, commercial properties and other facilities.
Treatments must follow product labels, occupancy restrictions and applicable safety requirements.
Farms and Agricultural Facilities
Some fogging equipment is used in agricultural pest management.
However, not every agricultural pesticide can be used in a fogging machine.
Only formulations specifically approved for the crop, pest, application method and equipment should be considered.
Warehouses and Storage Facilities
Fogging may form part of a professionally planned pest management programme in suitable storage facilities.
Special care is needed around food, animal feed, electrical equipment and sensitive materials.

How to Choose the Best Fogging Machine in Kenya
Check the Type of Fogger
Decide whether you need a thermal fogger or a cold fogger.
For outdoor mosquito control, professional operators may consider a thermal fogger.
For selected indoor applications, a suitable cold fogger may be preferable, depending on the approved formulation.
Consider the Tank Capacity
A small tank may be sufficient for occasional work.
A larger tank is more convenient for longer treatment sessions, but it adds weight.
Check the Starting System
Some machines use manual starting, while others have electric ignition.
Confirm the starting method before purchasing.
Check Chemical Compatibility
This is one of the most important buying factors.
A fogging machine must be compatible with the intended chemical formulation. Using the wrong formulation can damage the equipment, create a fire hazard or expose people to unsafe chemicals.
Ask About Spare Parts
Check the availability of replacement ignition components, hoses, seals, tanks and other parts.
Confirm Warranty and Servicing
Ask the supplier about warranty terms, maintenance support and availability of an operating manual.
Safe Operation of a Fogging Machine
Fogging equipment should be operated only by trained personnel following the equipment manual and the approved chemical label.
Before any treatment, operators should assess the site, identify people and animals who may be exposed, and establish suitable exclusion areas.
Important precautions include:
-
Use only approved formulations compatible with the machine.
-
Wear the personal protective equipment required by the chemical label.
-
Keep children, pets and bystanders away from treatment areas.
-
Avoid spraying near food, drinking water and exposed food preparation surfaces.
-
Never direct fog towards people or animals.
-
Avoid open flames and other ignition sources.
-
Do not operate petrol-powered thermal foggers in poorly ventilated indoor spaces.
-
Follow all re-entry and ventilation requirements.
-
Allow hot machine components to cool before handling or refuelling.
-
Store chemicals securely in their original labelled containers.
Fogging chemicals can be hazardous when inhaled or handled incorrectly. Professional pesticide applications should comply with applicable Kenyan pesticide and pest control requirements.
