Trapping sheep blowflies using bait-bins

A bait-bin designed to attract and kill sheep blowflies is described. It is composed of a garbage bin plus lid, attractant and insecticide-treated offal. Fly entry holes are covered with differentiator wire to increase selectivity of kill. Placing bait-bins in preferred habitats of blowflies to optimise kill is outlined and temporal insecticide strategies to increase effectiveness of kill and reduce blowfly resistance are suggested. Preliminary data supporting the effectiveness of bait-bins in reducing blowfly numbers and flystrike in combination with good management practices to reduce sheep susceptibility to flystrike in the arid zone of New South Wales are presented and cost-effectiveness of bait-bins is analysed.
