Tent fumigation is a process that is subject to a number of factors that can lead to success or failure. There are many factors that must be observed, considered, and accounted for when fumigating your home. Such factors must be assessed not only before the tent fumigation, but also during the actual tent fumigation day.
First, when your house is assessed, your home must be measured properly since the cubic volume plays a significant role in determining the amount of fumigant gas required to treat the home properly. A home that is under-measured may not receive the appropriate amount of gas needed to treat the home effectively.
The technician assessing your property must also consider the applicable ground conditions surrounding the structure. Since the structure must be enclosed to retain the fumigant gas for a certain period of time, the ground conditions under and surrounding the home must also be evaluated. Rocky or porous ground conditions may lead to gas seepage, whereas a concrete slab will provide a more optimum barrier to prevent seepage. Failure to observe this factor will impact the tent fumigation process and may impede achieving an effective tent fumigation treatment.
Your fumigator must plan the layout of his tarps to achieve optimum seals for your property. Failure to plan accordingly or working with poor measurements may lead to a shortage of tarps. If the tarps do not extend far enough from the home at the ground level when appropriate, an adequate tarp-to-ground seal may not be accomplished and may lead to steady gas leakage and sometimes, burning of nearby landscaping.
Careful consideration must also be extended for landscaping close to the structure. Your fumigator must first establish if those plants must be temporarily transplanted or trimmed back in order to avoid compromising an effective treatment. In some cases, plants close to the structure must be enclosed within the tarps to avoid a failed fumigation treatment.
The fumigator must be aware of the environmental conditions encountered on the day of tent fumigation. Such conditions include temperature and wind. Since the fumigant is a gas, the temperature will play a role in how well the gas will move throughout the structure. Your fumigator must be able to assess the likely average temperature within the structure during the fumigation period in order to determine the appropriate amount of fumigant gas to introduce into the structure under those conditions.
The speed of variable winds throughout the structural fumigation period will impact the retention of gas within the structure. Although the structure is enclosed, wind pressure pushing against and pulling away from the structure may cause billowing which results in a vacuum-like affect. Failure to account for this factor may lead to the loss of fumigant gas in greater amounts than usual.
In summary the following factors must be taken into serious consideration by your fumigator and work crew in order to achieve an effective treatment:
- Accurate measurement of the cubic volume of the structure
- Observance and accounting for ground conditions
- Proper planning for tarp layout, sealing and securing
- Adequately addressing landscaping impediments
- Accounting for average temperatures and average wind velocity
