Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
J R J French
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollution and contamination to the environment, emphasis on physical barriers has been refocussed. In the event of such barriers being penetrated, the use of suitable bait systems and toxicants is considered a fruitful "back-up" strategy in future termite control measures. Such a system is environmentally friendly, has wide public acceptance, and readily marketable.
