Termite Fumigation Process

Structural fumigation is used to control drywood termite colonies. This method is appropriate for homes with extensive infestations or colonies located in areas where it is not feasible to apply direct wood treatment.

Your termite expert can explain when to use a localized treatment or whole structure treatment (like fumigation) to control drywood termites.

What Happens During Termite Fumigation?
Since fumigation involves special pesticides, contact a certified professional to provide treatment. Fumigation is not a do-it-yourself project.

During the termite fumigation procedure, the professional will cover your home with a tent that is made of vinyl-coated tarps. Fumigation tents are used to minimize leakage of the fumigant, confining it to the infested structure.

Sulfuryl fluoride is the fumigant used to treat residential buildings. Certified experts are trained to calculate the exact amount of gas necessary to control active termite colonies. The gas disperses throughout the home to fill all air spaces, including small cracks and crevices in wood where termites may be living.

Throughout the fumigation process, your pest control expert will monitor gas levels with a dosage monitoring device to help ensure the right concentration is used and the treatment will be successful.

Structural fumigations typically take about 24 hours, though they can take as long as 72 hours. The size of your home and outdoor temperature are two major factors affecting the amount of time it takes for a fumigant to reach the proper concentration levels.

Once the tent is removed, the gas will leave your home quickly. After at least six hours, your pest control expert will test the home’s air quality with a clearance device that can detect trace amounts of fumigants. The reading on this device helps your expert determine when you can re-enter your home.
