Fumigation generally involves the following phases: First the
area intended to be fumigated is usually covered to create a sealed
environment; next the fumigant is released into the space to be fumigated;
then, the space is held for a set period while the fumigant gas percolates
through the space and acts on and kills any infestation in the product, next
the space is ventilated so that the poisonous gases are allowed to escape from
the space, and render it safe for humans to enter. If successful, the fumigated
area is now safe and pest free.
