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.
