The smell from fumigation typically lasts between 1 to 3 days, depending on various factors such as the type of fumigant used, the size of your home, & how well the area is ventilated. While fumigants are designed to dissipate quickly, some odors can linger longer than others.
Factors Affecting the Duration of Fumigation Smell
- Type of Fumigant
- Sulfuryl Fluoride (commonly used for termites) usually has a sweet odor and dissipates faster, often within 24 to 48 hours.
- Phosphine Gas has a stronger, garlic-like odor and may take a little longer to dissipate.
- Ventilation
- The more ventilation in the home, the faster the smell will clear. Professional pest control technicians will usually ventilate the home for 12 to 48 hours to clear the air.
- Home Sealing
- If your home was sealed tightly during fumigation, the smell may linger longer. Proper ventilation is key to removing the odor.
Fumigation smells typically fade within a few days. With proper ventilation, most odors should be gone within 1 to 3 days. Be sure to follow the guidance of your pest control provider for safe re-entry after fumigation.
