Localized spot treatments using chemical pesticides�serve as a remedial termite control method, but unlike tent fumigation it offers no guarantee for drywood termite elimination.� This is because spot treatments can only be applied to accessible areas where drywood termite activity has been detected.� Therefore, spot treatments only affect the termites in the immediate area that is treated.
The primary benefits of spot treatments for termite control are cost and convenience.� Spot treatments are significantly less expensive than whole structure fumigation and don't require you to vacate the structure.� The down side of spot treatments is that is significantly less reliable in achieving total eradication.�
The success of spot treatments is�heavily dependent on the technician's ability to locate all activity.� This can be difficult to determine in areas that are inaccessible, such as behind walls.� However, this method is often ideal if it is determined that the termite activity is isolated or confined to a specific detectable and accessible area.
Borates are derived from minerals and act as a stomach poison for target pests.� Lumber is often pre-treated with borates�prior to or during construction as a preventive measure against termite and fungus infestation.�
For existing structures, borates can be effective in eliminating small infestations of termites but it is typically considered a�remedial treatment and/or preventive treatment.��Borates can only be applied to bare/unfinished wood and because�borates are water-soluble they cannot be applied to exterior wood unless a finish or sealant is applied thereafter.�
Borates are usually applied by brushing or painting directly on the wood, spraying or fogging or by drilling into the wood and pressure injecting.� Successful eradication of existing drywood termite infestations is dependent on the technicians locating each piece of wood that is infested.
ORANGE OIL BASED PRODUCTS
These types of products contain high citric�acid content, which can be fatal to termites that feed on it.��The�product�does not leave an unpleasant odor behind and this treatment approach does not require displacement of the household occupants.�
However, total eradication of drywood termites cannot be guaranteed unless this product is delivered to all�infested wood�throughout the entire structure.��If the entire structure is not properly treated�or the product is not delivered to all wood members where termites exist, the existing termites will�be affected only if they consume one of the treated pieces of lumber within 96 hours of the initial application because�the product biodegrades within 4 days.
This approach is fairly new within the pest control industry.� It is considered an alternative measure for drywood termite control but has not been established as a method that guarantees 100% eradication or a method that provides prevention.
FREEZING WITH LIQUID NITROGEN
Freezing with liquid nitrogen (such as the Blizzard System and others) is different from other spot treatment methods.� This type of treatment is considered a localized treatment and requires that holes be drilled into the structure in order to deliver the product.� Because the mode of action for this type of treatment is thermal, success is highly dependent on dosage and detection accuracy is critical.� All undetected or inaccessible infestations will go unaffected by this treatment method.
