Fumigation is a method of controlling pest where fumigant (a combination of different chemicals that turn into gas when it reached a specific temperature and pressure) is discharged into a room or a tightly sealed and secured space to eliminate targeted pest.

The two most used chemicals are Sulfury Fluoride and Phosphine. Sulfury Fluoride is primarily used to eliminate SPI (stored product insects), moths in food factories and mills, wood boring insects, and Brown Marmorated Stink Bug. Meanwhile, Phosphine is used on food commodities and therefore frequently used for treatment on seeds and plant products, dry fruits, and other stored products.

There are different methods of fumigation: under cover sheet, structural, container, and silo. Fumigation starts by sealing off the space with a tent, except if it is already in a gas secure space. The duration of fumigation varies based on the type of infestation, temperature, dimension, size of the structure, and other factors.

It is important to note that having a licensed and professional fumigation provider is a must to yield a safe, effective, and efficient result. Not having a professional fumigation work done can be incredibly hazardous as it can harm human, animals, building structure, and its environment. It can also build a resistance against the targeted pest.
