Fumigation typically produces a strong, chemical smell that can vary depending on the type of gas used. Common fumigants, such as sulfuryl fluoride, often have a sweet, ether-like odor, while others may smell like chlorine or rotten eggs.

Common Fumigation Gases & Their Smells

• Sulfuryl fluoride – Sweet, ether-like odor

• Methyl bromide – Sweet & sometimes described as like chlorine

• Phosphine gas – A garlic or rotten fish smell

What to Expect During Fumigation

• The strong smell is usually noticeable before & after treatment.

• Ventilation is required after fumigation to eliminate odors & make the environment safe for re-entry.

While fumigation smells can be strong, they’re typically not harmful once the treatment area is properly ventilated. Always follow safety instructions & wait for clearance from pest control professionals before re-entering.
