Fumigation with formaldehyde vapor is the recognized and most commonly used method because it is a cost-effective procedure. However, alternative methods are sought due to safety and efficacy concerns. Vaporized hydrogen peroxide is a dry gaseous method that has been used as a reliable alternative for aseptic processing isolators, and more recently, for room/facility decontamination. Hydrogen peroxide and silver in solution and diluted in water is a non-toxic and low cost agent. For example, to fumigate a 1000

Post operation ventilation of the area is a critical safety aspect of fumigation. It is important to distinguish between the pack or source of the fumigant gas and the environment which has been fumigated. While the fumigant pack may be safe and spent, the space will still hold the fumigant gas until

as the pesticide (sulfuryl fluoride is a naturally occurring gas, used in much higher concentration than found in the natural atmosphere, and which leaves no physical residue). The fumigated structure can be re-occupied after the tent has been removed and the pesticide has dissipated to a safe level,

Structural fumigation techniques differ from building to building. In a residential setting, a "rubber" tent or tents, typically made of plastic/pvc coated canvas material, may be placed over the entire structure while the pesticides are being released into the vacant structure. This process is

Fumigation of hospital rooms with high concentrations of toxic chemicals has been proposed to reduce microbial agents on hospital surfaces and to control surgical site infections. Formaldehyde fumigation has long been an accepted method for areas where microbiological cleanliness is required.

Fumigation generally involves the following phases: first, humans are evacuated from the area intended for fumigation and the area covered to create a sealed environment. Next, the fumigant is released into the space to be fumigated. The space is held for a set period while the fumigant gas
203:. Commodity fumigation, on the other hand, is also to be conducted inside a physical structure, such as a storage unit, but it aims to eliminate pests from infesting physical goods, usually food products, by killing pests within the container which will house them.

Fumigation is a hazardous operation. Generally it is a legal requirement that the operator who carries out the fumigation operation holds official certification to perform the fumigation, as the chemicals used are toxic to most forms of life, including humans.
274:
At the heart of this technology is the use of chemicals. Ideally, these chemicals kill or passivate the targeted creatures without harming others. Usually such a feat is impossible, so fumigation is conducted in the absence of humans.

called tent fumigation, or "tenting". The sealed tent contains the poisonous gases and prevents them from escaping into the environment. This process is commonly used for the treatment of drywood termites and/or bedbugs, using

Each fumigation lasts for a certain duration. This is because after spraying the pesticides, or fumigants, only the pests around are eradicated.

Structural fumigation targets pests inside buildings (usually residences), including pests that inhabit the physical structure itself, such as
