Fumigants are gaseous forms of chemicals that are used to eliminate the pest risk. Anypest control product is NOT a fumigant. The main difference between a regular pest control product and a fumigant is that the fumigant, being in either a liquid or solid form is converted into a gas during the application process and it remains in the gaseous form during the entire fumigation period until the fumigation structure is aerated. Fumigants are very toxic and lethal to insects and in sufficient concentration it can also be lethal to humans and animals.
Insect pests or other pests found living in or around the product, also hide in hard to reach nooks and crevices in storage premises, food processing units, equipment, etc. None of the insecticidal formulations which may be sprayed in such places will be effective in containing the pests. It is only the fumigant which could penetrate such inaccessible spots and eradicate the pests. When a pest population warrants a treatment, fumigants are the best tool to penetrate into structures and commodities without leaving a dangerous residue. However, fumigants can be hazardous and deadly and require a specialised team to apply the fumigant and carry out the fumigation process.
