The answer to 'what causes fumigation' is that fumigation is a method of pest control that involves releasing toxic gases to eliminate insects, rodents, or other pests from a confined space, such as a building or structure. Fumigation is typically used for large-scale pest infestations that cannot be effectively treated using other methods, such as spraying or baiting.
The gases used in fumigation are highly toxic and can be dangerous if not handled properly. Common fumigants include methyl bromide, phosphine, and sulfuryl fluoride. These gases are released into the targeted area, where they penetrate cracks and crevices to reach and kill pests. After the fumigation process is complete, the area must be ventilated to remove any remaining gas before it can be safely re-entered.
