FUMIGATIONIn many situations, the use of residual pesticides has replaced fumigation as a means of dealing with pest problems. However, fumigants will have a place in the future of pest control, not only because of their ability to eliminate a broad spectrum of pest, but because they are our only choice when penetration is needed to solve a pest problem. Fumigation is especially useful for dealing with stored products pest and pests such as powderpost beetles inside wood.
Fumigation is the introduction of a toxic gas or smoke into a space -whether a building, grain elevator, railcar or rat burrow- in a high enough concentration so that the gas or smoke fills all areas to kill target pests. It is the method of choice when pests are located in areas that are inaccessible to conventional treatments.
The choice of the proper fumigant for any specific purpose is determined not only by relative effectiveness but also by cost; safety to human beings, animals and plants; flammability; penetration power; effect of germination of seeds reactivity, etc. Fumigants are employed a control a great variety of pests under many different conditions (temperature, sealing, etc).
Fumigating gases may react with certain metals and their salt to produce corrosion. The gas is corrosive to copper, copper alloys and precious metal such as gold and silver. Sensitive equipment and items containing these elements should be removed or protected prior to fumigation. Fumigant products are phosphine - methyl bromide - ethylene oxide, etc.
Less toxic and "dangerous" in damages, but also effective, fumigation can be applied by fogger or ULV machines or smoke generator canisters.
All these products and mechanical means are available in our company.
SAFETY: ALL FUMIGATING PRODUCTS ARE EXTREMELY TOXIC.
Fumigation treatment must me applied only under guides of experienced Supervision (Fumigator in charge).
- Be fully acquainted with the general structural layout, connecting structures, adjacent structures and escape routes, above and below ground.
- Check equipment to be sure product flow has stopped and equipment is as tight as possible to prevent drafts and/or leaks.
- Plan to keep people from entering the fumigated area by using one or more of the following: watchman, warning agents, fumigator's locks and barricades.
