Question DetailsAsked on 9/29/2013

what are the benefits of termite tent fumigation versus foam spray?

I have heard that tenting only kills termites that exist now and once the gas is gone in two days, they are free to return. spraying foam into the walls may keep them away longer because the foam leaves a residual that keeps them out. Is this true?

Spraying foam into the walls may leave some residual protection, but three downsides -

1) you now have a toxic chemical permeating your house that you continually breathe in - if they put enough in the walls to protect the entire house, I can tell you I would not want to come to your house

2) foaming inside walls promotes mold and fungus inthe walls

3) the foaming only works where it is done, so only where the infestation was

For complete treatment, the best program is total openings sealing (to keep out flying termites), tent fumigation, then a regular exterior treatment program to keep burrowing termites out.

Even companies who perform fumigations disclose that as soon as the tent is removed insects can immediately begin to reinfest the structure. For whole structure termite remediation, the Thermal method is the best choice for many reasons. The Thermal method is 100% Non Toxic, whereas the fumigation method is highly toxic and has caused sickness, brain damage and death. Thermal Termite remediation has been successfully and safely employed for over 20 years and it kills not only the termites but also their eggs (the highly toxic fumigant is not ovicidal) and it is used in conjunction with a non-toxic Borite solution that is applied to exposed wood and which repels termites if they reenter the structure. Aside from being highly effective in killing termites, the Thermal Method can be completed in only one day so there is no lengthy evacuation as is required when using the highly toxic fumigation method. People can be and have been sickened or killed from the use of fumigants like "Sulfuryl Fluoride" which is sold under several brand names such as "Vikane" or "Zythor". The EPA reports that Sulfuryl Fluoride is rated as a Category I nerve toxin which can cause damage to the brain. Also, M.I.T. scientists published studies in 2009 showing that Sulfuryl Fluoride is 4,800 times more damaging as a green house gas than carbon dioxide. In California alone it has been estimated that the amount of sulfuryl fluoride being released into the atmosphere during one year from fumigations is equivalent to adding an addition one million cars on the roads. The warming of our planet can be seen not just by the melting polar ice caps, but by the need for places like Miami, Florida to re-write portions of their building code to address the rising water level.

First of all in order to properly explain how FOAMING with Termidor SC and borates MATERIALS or both are highly effective... not only for the exterminating of existing termite colonies but most importantly in keeping them away for long term through residual crystall

ization of the wall studding In the structure - one must first understand how these materials work and how termite’s work.

First of all termites are gluttons and they are constantly looking for new food sources. When damage repairs are done it is typical to find termites traveling from as far as 25 or 30 feet away to one or two tiny kick-holes in order to deposit their fecal matter outside of their galleries or tunnels. They typically follow pheromone trails and will move through their network of tunnels back-and-forth and a Track like pattern eventually getting back to the Kick that the inspector or homeowner usually and sees what would be called active in the station point .

Because of this behavior pattern which is similar to ANTS and one can most notably see this through the side of the plexi glass panel in a sand filled ANT farm - Just as in this example termites also travel through portions of the structure just like the tunnels you see carved in the sand in an ant farm. When term adore foam is shot directly through a pressurized system into these pickles and termite galleries sometimes filling up the galleries as much is 5 feet or more away...The material that is used as non-repellent and so therefore it does not kill the termites right away but allows the termites they go through the contaminated area and as the termites meander and travel through the tunnels going back to their nest and then back to the cut holes each and every termite in the colony will be contaminated by the product and will die. Because it is a non-propellant material for termites and I understand they are dying and continue to follow this pattern of behavior and travel using pheromone trails.

The number one reason to not have your structure or a home fumigated besides the damage to the roof to the fence to electrical and powerlines cable lines fences and shrubbery with your fumigator will make you sign waivers for everything while at the same time simultaneously watering down the possibility of damage so that they can complete their sale and ethically...And also a really good chance of burglary... is the fact that the fumigation gas leaves absolutely no residual in the structure and therefore of the fumigation does not work and that usually does not work 10 to 15% of the time when there is nothing left in the home to kill the remaining termites . In the best case Scenario and assuming that the tent fumigation actually works...There is still absolutely no residual protection for re-infestation and in areas of Southern California and central California where Drywood termites can swarm as much as four or five times a year your home will quickly be reinfested within days or weeks after you spent an incredible amount of money. Tent fumigating your property or virtually no reason. Tent fumigation simply does not provide any type of long-term solution. This type of termite control does not afford any type of peace of mind neither with the fumigation process itself nor with the fact that it might not have even worked at all and unfortunately the reality that it will not even work one hour after the TENT is removed from your home.

When borate phones are used in the perimeter framing of the wall voids and other cornices and soffits and high moisture walls and bathrooms and kitchens were termites typically enter the structure and harbor ...Not only are these materials highly effective in killing existing termites but will last for years and years to come. Independent studies say that the residual a borates can last as much is 10 or 15 years plus plus alternative treatment companies that provide a termite extermination process using these materials and techniques typically warranty and their service a lot longer than a tent fumigation simply because they work better.

So I would challenge anyone entertaining the idea of having their house exterminated especially for Drywood termites of the pros and the cons . Keep in mind that if you choose tent fumigation over a termodor and borate treatment...You’ll have to go through not only a horrible inconvenience of leaving your home in which you do not have to do with a foaming treatment that you also subjugate your property and your home to much damage and you will have to sign waivers releasing the fumigation company from this type of expected damage as well as taking the risk of getting your house burglarized while the fumigation process is being performed. Lastly he will not have a termite solution in the residual protection that will keep killing Termite for years and years and years to come. Do you really want to take that risk?
