What is fumigation?
Fumigation is a method of using a lethal gas to exterminate pests within an enclosed space. There are two fumigation methods used. One is to seal the structure with plastic, tape, or other materials, and the other is to enclose the structure in a tent of vinyl-coated nylon tarpaulins. 

How can I tell if my house has been fumigated?
Since 1961, the law requires that, when a fumigation is complete, the fumigator must post a sign with the name of the licensee, the date of the fumigation, and the fumigant used. The sign must be posted either in the attic or in the subarea of a house, such as a garage. The sign mustremain permanently attached.

What must be done before a house is fumigated?
All people, pets, and plants must be removed fromthestructurebeforefumigation.This includes fish and seeds or bulbs intended for planting. Medicines, feed, and food not sealed in metal, glass, or highly resistant containers must be removed from the structure or sealed in protective bags as recommended by the fumigant manufacturer. Ask your fumigator any questions you have about the process and preparations.
