How long does fumigation take? Does it leave behind a toxic residue? Fumigation typically takes two-and-a-half to three daysâif we start on a Monday, you could be back in the house on Wednesday evening. The fumigant is an odorless, colorless gas, not a mist or spray. Thereâs actually a warning agent thatâs added to it so you know when youâre exposed, much like the gas company adds an odor to natural gas so you can smell a leak. The fumigant doesnât leave behind any residue or odors.
