Pest fumigation is a pest control method that fills an entire building with fumigants which will either poison or suffocate the pests inside. In some cases, the use of fumigation may be the most effective way of eradicating infestations of certain solid wood boring insects that can cause extensive property damage. During the fumigation process, the infected area is enclosed in a tent-like structure and properly sealed to be gas-tight, preventing the leakage of fumigants.
Once enclosed, the infected area is cordoned off for at least 24 hours, which is referred to as the exposure period. After the fumigants have performed their function, the infected area is aired out and what little amount of gas that remains is completely risk-free to humans. The fumigation method has proven to be very effective in killing pests and by rapidly infiltrating through grains as well as various structures where infestations thrive, and contrary to popular belief, fumigants do not leave behind toxic material that can harm human beings.
