Terro 4 Pack Fly Ribbons. These sticky ribbons are effective in catching nuisance flies and other flying insects indoors, outdoors, in gardens, and on lawns. They require no baiting or poisons, making them safe for use around children and pets. Simply hang the tube in an area of flying insect activity and unravel the ribbon to expose its sticky surface. Once an insect comes in contact with the Fly Paper, it sticks to it and stays there. Odorless and mess-free, these traps can be quickly disposed of once they fill with flies. Each package contains 4 Terro Fly Paper traps.
