What is a fumigant?

A fumigant is a type of pesticide typically in a gaseous form that is designed for use in enclosed spaces. This method of pest control is particularly effective for targeting pest infestations that are difficult to reach or eliminate through other means. Fumigants work by penetrating solid materials, such as soil or stored products, and can exterminate pests, eggs, and larvae that may be hidden within those materials.

This application method requires specialized equipment and training because fumigants can pose health risks to humans and the environment if not used correctly. By filling a space with gas, the fumigant achieves a concentration level sufficient to affect pests effectively while remaining contained within a controlled environment, which is crucial for safety and efficacy.

In contrast to other forms of pesticides, such as solids or liquids used for surface application, fumigants specifically rely on their gaseous nature to provide deep penetration and comprehensive coverage against pests.
