Termite Protection Update
Eradication of any existing termite infestation is important to stop the damage spreading. This is usually done by applying an APVMA registered product, registered for this purpose to active termite workings. The termites then consume the bait or consume the dust/ wear the dust and take this back to their nest via feeding, grooming etc and pass it through the nest. In most circumstances the preference is for a baiting program to eliminate the colony and queen completely.
If the nest can then be located by the technician it may be physically destroyed by breaking it up or an insecticide can be applied to the nest, killing it directly. The workings and bait can then be monitored to determine that the nest was associated with the Termites causing the damage.
Once the nest is eradicated, any termites remaining in infested timbers will die out but to reduce damage should be continually treated until all activity is gone. However, the home is not protected against re-infestation from other nests and future nests.
Before applying a Liquid Termiticide treated zone you must first always eliminate the colony by using dusts or baits or foam. (Note: Arsenic Trioxide Termite Dust does not work on some genus of termites and is only about 60% effective on others. It is also a Schedule 7 Poison. ) Applying a Liquid Termiticide to Active Termites will generally not result in colony elimination as those Termites effected will be effected too quickly and repelled by the colony and die before the poison can be passed through the colony, resulting in the colony surviving and later re-attacking dwelling at an alternative source.
Although sometimes the baiting method is criticised as being too slow, for long term protection it is always the most reliable method and cost effective in the long term due to the elimination of a colony which may have a 30 year life of economic damage.
