Foggers are devices used to disperse pesticides, disinfectants, or other chemicals in the form of a fine mist or fog. They are commonly employed in agriculture, pest control, and sanitation to cover large areas quickly and efficiently. Foggers can be powered by electricity or gas and come in various sizes, from handheld models to larger machines for extensive applications. There are two main types of foggers: cold foggers and thermal foggers. Cold foggers use a fan to create a mist without heating the solution, while thermal foggers heat the liquid to produce a dense fog. Both types are effective for targeting insects, mold, and bacteria in different environments.
