Protect plants from whiteflies, aphids and other flying insects. Lasts all season, even in rain, or until completely coated with insects or dust. Peel trap apart, reverse fold, sticky side out. Hang with supplied twist-tie from branch or stake at plant level. Place traps every 7' or at end of each row. For badly infested plants, shake plant gently and flies will swarm a few moments before they fly to your nearby trap like iron filings to a magnet. Thrips, leaf miners, gnats, fruitflies, leafhoppers and froghoppers are also attracted to these traps.
