Evaluating a termite interception and baiting system in Australia, Thailand and the Philippines

Abstract

The Exterra Termite Interception and Baiting System (Ensystex Inc., Fayetteville, NC) was evaluated in field experiments in Australia, Thailand and the Philippines. Cellulose-acetate powder containing chlorfluazuron (RequiemTM) was tested for its efficacy in eliminating colonies of various mound-building subterranean termite species. Using 0.05% and 0.1% weight/weight chlorfluazuron, there was no evidence of repellence and all colonies were eliminated. Colony elimination was confirmed by destructive sampling. Indicators used to monitor colony health were reliable. A suite of urban trials, demonstrating the effectiveness of Exterra Requiem Termite Bait in controlling a wide range of subterranean termite species, is also presented and discussed.
