When a pest infestation is particularly severe or a insect that cannot be controlled with traditional methods, one of the only forms of pest control is managing the infestation through the use of fumigants. Fumigants are important components in pest management programs due to their unique ability to travel throughout a common airspace and into microscopic voids to eliminate a wide variety of pests. Fumigation is especially helpful in controlling pests which infest residences and places of business, processed food and wood products and may be the best option to take in situations where other means of pest control will not get the kind of reach of fumigation.

On this page we will provide you basic information on fumigation, the pros and cons of using fumigants and how to properly conduct DIY fumigation around your home to eliminate pests. You can also shop the top recommended fumigant (gas) products we have in stock.

What are Fumigants? What Is Fumigation?

Fumigants are pesticides which form a gas and are toxic to animals, plants and microorganisms when they are applied. By definition a fumigant is “a chemical which, at a required temperature and pressure, can exist in the gaseous state in sufficient concentration to be lethal to a given pest organism.

The key components which allow a fumigant to be effective includes: 1) the chemical and physical properties of the chemical gas selected to be used, 2) the duration of time the pest is exposed to the fumigant, 3) the temperature at the site of the target pest, 4) the susceptibility of the target pest and the various life stages present, 5) the leakiness of the airspace and 6) any safety measures that must be followed.

Some active ingredients of fumigants are liquid in their packaging but then get change into a gas when released while others remain as gases through formulation, packaging, and release. Other active ingredients are volatile liquids when enclosed in an ordinary container and, therefore, are not formulated under pressure. Others are solids that release gases when applied under conditions of high humidity or in the presence of water vapor. Some can even be aerosols which exert enough pressure to create a fumigation effect when released but technically do not qualify.

The most commonly used fumigants in the US are phosphine (hydrogen phospide), sulfuryl fluroide, and methyl bromide. Fumigants have differing modes of action but in all cases there is some type of lethal reaction to the chemical which results in suffocation.

Pest control professional often prefer fumigation as their method of choice for typical large infestations that have reached out of control proportions or are in areas that cannot be easily accessed by traditional methods. There is usually less labor involved when it comes to fumigation as well since an entire area is being treated rather than inspecting and spot treating specific areas and it can be a more rapid method of controlling an infestation too for people that want a quick fix.

Fumigants are used for structural pest control, in food and grain storage facilities, and in regulatory pest control at ports of entry and at state and national borders. In agricultural pest control, fumigants are used in soil, greenhouses, granaries, and grain bins.

Benefits of Using Fumigants or Gas

Some of the biggest advantages that fumigants has which makes it stand out as an effective form of pest control is that fumigants are commonly toxic to all forms of life (insects, mammals and birds) so by conducting a fumigation, you can take care of multiple infestations you may have in a structure.


Fumigation chemicals are also able to get through inaccessible areas than conventional contact and residual insecticides. Where typical treatments would be unable to penetrate, fumigants can get into cracks, crevices, woods and tightly packed areas to kill even the best pest hiders.


A single treatment of fumigants usually kills most pests so there may be no need for a follow up. This also makes fumigants less expensive overtime compared to the need for repeated treatments of other types of formulations


Drawbacks of using Fumigantsfumigant drawback

Some disadvantages that fumigants have is that often times the place to be fumigated cannot be adequately sealed for proper fumigation to occur, which isn’t necessarily a fault of the fumigant.


Fumigants are also risky because they are nonspecific to who they harm and can be toxic to humans as well. Fumigants also require people to vacate the area for time until the treatment is complete and the fumes has dissipated.


Sometimes when it comes to fumigation, the target insect would escape and return once the fumigation is complete. Fumigation can also be more expensive to do and would require a lot of specialized equipment.

Popular gas type products we have in stock.
