This unique product is easy to use; simply place the strip in enclosed, non-food areas. Once Fruit Fly BarPro Fly Strip is removed from the foil package, the air immediately activates the pest control ingredient. The product works similar to an air freshener, as the time released vapor moves into the crevices. Not a fly trap. Rather than attracting bugs, as a fly trap, the vapor reaches nesting areas for total elimination. The Strip will treat the infested area for up to 4 months. Fruit Fly BarPro is a cost effective alternative to expensive extermination services. - Length 10 in - Width 4 in - Thickness 1 in - Sold per case; 10 per case
