To prepare for home fumigation, follow these steps: vacate the house with all occupants, including pets and plants; remove or seal food, medications, and other consumables in special fumigation-safe bags or take them off-site; open drawers, cabinets, and closets to allow fumigant penetration; turn off gas lines and appliances as directed by the fumigation company; remove bedding and pillows or seal them; ensure all windows are closed and any specific instructions provided by the extermination team are followed. These measures ensure safety and effectiveness during the fumigation process.
