During fumigation, windows are typically not left open. In fact, pest control professionals seal off the entire structure to ensure the fumigant stays contained within the home. This helps the gas penetrate effectively, reaching all pests hiding in cracks, walls, & other hidden spaces.

Why Are Windows Closed?

• Effective Treatment – Keeping windows and doors sealed ensures that the fumigant stays inside, allowing it to work properly & reach all areas of the home.

• Safety – If windows were left open, the gas could escape, posing safety risks to people & pets nearby.

• Controlled Environment – A sealed environment helps maintain the right concentration of fumigant to eradicate pests efficiently.

What Happens After Fumigation?

Once fumigation is complete, the home is ventilated, & windows may be opened to air out the space, ensuring it’s safe to re-enter.

Windows remain closed during fumigation for safety & effectiveness. Afterward, the home is aired out to ensure a safe environment for re-entry.
