A thermal fogger is a device used to create a fog-like mist of pesticide or disinfectant. It works by heating a liquid solution, which turns it into tiny droplets that can easily disperse into the air. This method is often used for pest control in outdoor areas, such as gardens or parks, as well as for sanitizing large spaces. These foggers are popular for their efficiency in covering large areas quickly. They are commonly used by professionals in the pest control industry and can also be utilized in agriculture to protect crops from insects and diseases.
