Why do people need Tent Fumigation for their homes?
Tent Fumigation is the only reliable way to totally control and eliminate certain insects such as the drywood termite and wood boring beetle. Unchecked, wood destroying insects can do considerable amounts of damage to structures that are build from or contain wood. People will decide to Tent their homes when one of these insects has spread to the entire home and it is the best solution to eliminate them. Unlike surface or localized injection treatments, sulfuryl fluoride fumigant gas penetrates to every possible point of the structure where a target insect may be located, no matter where within the structure it is located or what surface it may be behind.
What is Sulfuryl Flouride?
Sulfuryl fluoride is the fumigant gas. The molecular formula is SO2F2. Sulfuryl fluoride is an inorganic compound (does not contain carbon). It is as good choice as a fumigant because it has high penetrating power plus it does not adversely react with items normally found within structures. It is non-staining, non-corrosive, and non-flammable plus it does not deplete the ozone layer.
How are structures fumigated?
The objective of the fumigation process is to create a sealed space within which the target insects are located and which the fumigant gas can be confined. A structure is covered with a gas tight tent that seals the fumigant and bugs inside of the structure. The amount of time that the structure must be tented can range from 2 hours to as long as 72 hours with an average required time of around 20-24 hours. The amount of time for exposure is calculated by the fumigator and s/he will take into account the type of insect being targeted, the temperature of the air within the fumigated space and the length of fumigant exposure period.
What happens after the fumigation is completed?
At the end of the fumigant exposure period, the fumigation seal is removed thereby allowing the gas to escape into the atmosphere. Aeration is normally aided by opening windows and the use of electric fans. The sulfuryl fluroide will dissipate rapidly from the open air spaces of the structure out into the atmosphere once the aeration process begins. At the completion of certain periods of time during the aeration process, the fumigator will use a specialized monitoring device to measure the amount.
After the fumigation is completed:
-Do not attempt to reenter or reoccupy the structure until you are told by your fumigator that the structure is clear for reentry.
-If you are interested or concerned, you should ask your fumigator to show you the records of how your structure was aerated before it was cleared for reentry.
-It is not necessary to wash dishes, linens or clothes exposed to Sulfuryl Flouride.
-You may wish to increase ventilation of your structure by opening doors and windows for period of time after your return. This may reduce the chances of encountering any residual chloropicrin warning agent.
