Exceedingly effective. Ideal for smallholdings, poultry farms, dairies - or anywhere plagued by flies every summer. Low cost, easy to use and disposable. Catches up to 20,000 flies every trap and once trapped they cant escape. Bait is especially appealing to female flies - so reducing the next generation. Simply hang the fly trap away from the area you wish to protect. Bait lasts 4-6 weeks.Please note Images shown may not represent exact sizes colours types etc
