Fumigation usually takes 24 to 72 hours, depending on the size of your home, the type of pest, & the fumigant used. The total time includes preparation, gas exposure, & ventilation before it’s safe to return.
Breakdown of the Fumigation Process
Preparation (Few Hours to a Day)
Before fumigation, you’ll need to prepare your home by removing food, plants, and pets, & sealing certain items.
Fumigation (6 – 24 Hours)
The home is sealed with a tent, & fumigant gas is released to penetrate all areas, targeting pests at every life stage.
Aeration & Clearance (12–48 Hours)
After treatment, the home is ventilated. Technicians test air quality to ensure it’s safe before you can re-enter.
What Affects the Timeline?
- Home size & layout
- Type of pest being treated
- Weather & environmental conditions
- Fumigant type & dosage
Plan to be away from your home for 2 – 3 days during fumigation. Your pest control provider will give a more specific timeline based on your situation. Always wait for the official clearance before returning.
