During fumigation, pest control professionals follow specific steps. Preparation involves vacating the property, sealing consumables in protective bags, and removing pets and plants. After preparation, the structure is covered with an airtight tent to contain the fumigant gas. The gas is introduced and allowed to circulate, reaching all parts of the structure to eliminate pests. Equipment is used to monitor gas levels to ensure proper concentration and safety throughout the process. After fumigation, the structure is aerated to remove residual gas and tested to confirm it is safe for re-entry.
