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 utilized for control of pests in a home or commercial building (structural fumigation). This method also affects the structure itself and the pests that inhabit the physical structure, such as termites.
Fumigation Typically Includes the Following Phases:
- The area intended to be fumigated is usually covered to create a sealed environment.
- The fumigant is released into the space to be fumigated.
- The space is then held for a set period while the fumigant gas percolates through the space and acts on and kills any infestation in the product.
- 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 fumigating techniques may be different from building to building, but in residential homes, 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 depends on the severity of infestation and size of the building.
