Termite tenting, also called fumigation, is a method of treating large infestations of dry wood termites. Because the procedure is very expensive, it is recommended that there be evidence of a large infestation before resorting to this method of killing termites. However, despite persistent concerns, there appears to be no lasting residue or risk of injury to humans and pets once the procedure has run its course and the tent has been removed.
There are some limitations to termite tenting such as it does not reach unhatched eggs and does not prevent new colonies from invading a treated structure, although in response to the former experts say that is not a problem since when the eggs hatch there will not be any workers available to feed the nymphs which means they will starve to death. In addition, this form of treatment is ineffective against subterranean termites. Notwithstanding these shortcomings, the procedure has proven to be effective when used as prescribed and some states require that it be used before a house is sold. This wide spread use and presumed effectiveness have not reduced environmental concerns and environmentalists continue to object to the use of the process.
Tenting involves covering your house with a tent or tarp and then flooding the house with a gas, the most widely used is Vikane or sulfuryl fluoride, which penetrates the wood killing the unwanted guests.
The gas is said to be odorless and tasteless and should clear from the house by the time the tent is removed and the house is aired out before people and pets return. This type of treatment involves lots and lots of preparation and requires you and other family members to leave the house for one or two days and even longer periods at times. It reduces stress if the family makes a vacation out of the event or take this opportunity to visit the grandparents.
Given the extensive and time consuming preparations needed to use fumigation, as well as its cost, and environmental concerns, some experts say it should be used as a last resort. However, some states mandate that it be used as a first choice and so those faced with a dry wood termites infestation will want to consult with several experts in pest control to decide how best to proceed.
