What type of fogger uses heat to create smaller droplets from oil-based insecticide formulations?

Thermal foggers are designed to use heat to convert oil-based insecticide formulations into very fine droplets, creating a fog-like mist that effectively disperses the pesticide. The heating element within a thermal fogger vaporizes the insecticide, allowing it to be expelled through a nozzle as aerosolized particles. This is particularly advantageous for achieving better penetration into dense foliage and other challenging environments where pests may be hiding.

The choice of thermal foggers is ideal for applications requiring a rapid knockdown of insects in a variety of settings, making them highly effective for both residential and commercial pest control. Their ability to produce smaller droplets ensures that the pesticide remains airborne longer, thus enhancing its contact with targeted pests.

In contrast, ULV foggers utilize a specific mechanism that generates ultra-low volume sprays without the need for heat, aiming for larger droplet sizes. Cold foggers operate on a similar principle, using a fan to disperse cool air mixed with the insecticide but do not produce the small droplets associated with thermal fogging. Aerosol foggers, while convenient, typically deliver a fixed aerosolized product rather than allowing for the custom formulation associated with thermal systems.
