Viagrow Stick Traps protect plants from aphids, whiteflies, mosquitoes, gnats, thrips, leaf miners, fruitflies, leafhoppers, froghoppers, and other insects. Effective and easy to use, this non-poisonous trap works well when hung at stake or plant level and comes with twist ties to use for hanging. Place traps every 7 feet for best results. For heavy infestations, shake the plant to allow the insects to swarm and then set the trap. Viagrow Sticky Traps last all season, even during rain, or until thoroughly covered in dust and/or insects.
