In short, a fumigation is done by introducing a fumigant (gas) into the structure and holding the fumigant at high levels using “a tent” covering the structure. There are other methods that do not require a tent, known as tape and seal fumigations, however, most fumigations are tent fumigations. Once the target exposure period is reached and the insects are eliminated, the tents are removed and the home begins to aerate. Once all the fumigant has left the home and the air quality has been tested and deemed safe, then the home is released back to the owner.
