Future termite control requires partnership between industry, government and people
2006 - IRG/WP 06-10586
Given the behaviour of the pest control industry, together with the housing and timber industries, and performance of the State regulatory agencies, it is not surprising that all of these groups were philosophically ill-prepared to consider alternative measures in June 1995. However, conditions have altered and there is an awareness of such alternatives. In future, termiticides will have propertie...
