The Sticky Thrip Leafminer Traps do the following things:
• Protects plants from Thrips and Leafminers. Excellent protection for roses. Hang at plant level. Place traps every 7 feet apart or at end of each row.
• For badly infested plants, shake gently and flies will swarm a few moments before they fly to your nearby trap.
• Lasts all season, even in rain, or until completely coated with insects or dust.
