Fumigation is a method of pest control that completely fills an area with gaseous pesticides—or fumigants—to suffocate or poison the pests within. It is used to control pests in buildings (structural fumigation), soil, grain, and produce, and is also used during processing of goods to be imported or exported to prevent transfer of exotic organisms. This method also affects the structure itself, affecting pests that inhabit the physical structure, such as woodborers and drywood termites
Fumigation generally involves the following phases: First the area
intended to be fumigated is usually covered to create a sealed
environment; next the fumigant is released into the space to be
fumigated; then, the space is held for a set period while the fumigant
gas percolates through the space and acts on and kills any infestation in the product, next the space is ventilated so that the poisonous gases
are allowed to escape from the space, and render it safe for humans to
enter. If successful, the fumigated area is now safe and pest free
Structural fumigation techniques differ from building to building, but
in houses a rubber tent is often placed over the entire house while the
pesticides are being released into the vacant residence. This process is
called tent fumigation or "tenting". The sealed tent concentrates the
poisonous gases and prevents them from escaping into the neighborhood.
The process can take up to a week depending on the fumigant used, which
in turn depend on the severity of infestation and size of the building.
