COMBINING PHYSICAL BARRIERS, BAIT AND DUST TOXICANTS IN FUTURE STRATEGIES FOR SUBTERRANEAN TERMITE CONTROL (ISOPTERA)

Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termite penet ration in Australia and around the world. However, no barrier can give 100 per cent protection. Given the worldwide problems of using cyclod iene termiticides, public awareness of chemical pollution and contamin ation to the environment, emphasis on physical barriers has refocused. In the event of such barriers being breached, the use of suitable bai t systems and toxicants is considered a fruitful ''back-up'' strategy in future subterranean termite control measures. Such an integrated sy stem is environmentally friendly, has wide public acceptance, and is r eadily marketable.
