Alternative Treatment For Drywood Termites
Termites cause over 5 Billion dollars worth of damage in the entire nation. Two major types of termites are subterranean termites and drywood termites. The difference being that subterranean termites have their nest or colonies under ground. Their colonies tend to be large and can have more than a million individuals. Drywood termites on the other hand live on the wood itself. Colonies are small relatively anywhere from less than a hundred to a few thousands. However, drywood termites spread much more quickly and can establish several colonies throughout a structure.
Fumigation using Vikane gas (sulfuryl flouride) has been the most widely used for the control of drywood termites. This method is considered as the most efficacious since if done properly, ensures 100% mortality of all drywood termite colonies within structures. However, there are drawbacks with this method. The most common is damage to roofing materials. Since the fumigators have to step on the roofs carrying a 100 lb. tarp, roof covers such as tile, slate or even older composition roof can break or tear. Preparations can be a hassle too. Food and medicine items have to be taken out of the house or bagged in special Nylofume bags for protection. Plants, shrubs and trees that are close to the roof line or walls have to be trimmed.
Another disadvantage is vandalism and theft. Although structures are covered with tarp and warning signs are posted, brave and dumb criminals still courageously break in when the tarp is taken down.
Health concerns is one major factor. There are some reports that Vikane can still dissipate inside structures even after the structure has been cleared for re-entry. Some materials such as wood, latex and rubber can absorb Vikane and continuously release small amounts. Illness and death have been reported as a result of Vikane fumigation.
Nowadays, several treatments are available. Among the most popular uses microwave devices, high voltage-low current electrical devices, liquid nitrogen, orange oil and other registered pesticides. These types are localized treatments wherein the treatment is targeting specific colonies. Even though these methods are not recognized as 100% eradication, advantages are numerous.
Several of these treatments do not use chemicals therefore toxicity is not an issue. Damage to roofing materials is avoided in most cases. And homeowners do not have to leave their homes for several days. Since these methods are localized, it may be good to have a program that includes follow-up inspections and treatments.
