A brief outline of current non-chemical barriers in subterranean termite control and their use in Australia is presented. Recent use of non-chemical barriers in Hawaii has led to their evaluation in termite control here and elsewhere. In Australia, preliminary laboratory and field experiments have shown similar results to those found against Coptotermes formosanus in Hawaii, namely, Australian Coptotermes species do not penetrate intact barriers. Suggestions are offered to standardise laboratory and field evaluations of non-chemical termite barriers, with a discussion on the market potential.
