Fumigation is a highly effective method used to eliminate severe termite infestations. While the process can successfully wipe out an entire colony, it does require you to leave your home for a period of time.

Typical Re-Entry Timeframe

Most homes are safe to re-enter 24 to 72 hours after fumigation, depending on the gas used, the size of your home, and local regulations. Your pest control company will provide a specific timeline and clearance based on your situation.

Why the Wait?

The fumigant used often is sulfuryl fluoride it is a powerful gas that penetrates walls, floors, & furniture to kill termites. While it doesn’t leave a lasting residue, it must fully ventilate before the home is safe for re-entry. Waiting ensures…

• Complete dissipation of toxic gas

• Safe oxygen levels inside the home

• No risk of respiratory or health issues

Clearance Process

Before you can return, a licensed fumigator will…

• Ventilate the home to remove all traces of the fumigant.

• Measure gas levels using specialized equipment to ensure it’s safe.

• Post clearance signs at entry points once the home is deemed safe.

Never enter the home before the clearance is officially given, even if it appears safe from the outside.

What to Do After Fumigation

Once you’re back inside…

• Open windows and doors for extra ventilation.

• Wipe down surfaces, especially in kitchens and bathrooms.

• Check food and pet items that were left behind, they should have been sealed or removed during prep.

• Avoid deep cleaning carpets or walls immediately, unless advised otherwise.

You can typically return home 24 to 72 hours after fumigation, but always follow the timeline and safety guidelines given by your pest control company. With proper preparation and post-treatment care, fumigation is not only safe but also one of the most effective ways to eliminate termites for good.
