Insect Traps

About

Insect Traps & Sticky Traps for Grow Rooms Insect traps serve two critical functions in an integrated pest management program: monitoring and mass capture. Monitoring traps detect pest species presence and population trends before infestations are visible on plants - a single yellow sticky card showing 5-10 fungus gnats or whiteflies per week signals an emerging population that can be addressed proactively, rather than discovering a full infestation when plant damage becomes visible. Mass capture traps suppress low-to-moderate pest populations through continuous removal of flying adults, reducing the reproductive rate and egg-laying activity that drives population growth. Trap Types by Target Pest Yellow sticky traps attract a broad range of pest insects through their color - flying insects orient toward yellow wavelengths associated with foliage and flowers, making yellow the most broadly effective trap color for grow room use. Targets include whitefly adults, fungus gnat adults, shore fly adults, aphid alates, and leafminer adults. Blue sticky traps specifically attract thrips adults more effectively than yellow - include blue traps alongside yellow for grow rooms with active thrips pressure. Pheromone lure traps target specific pest species alongside beneficial insect programs by deploying synthetic versions of insect sex pheromones - the most powerful attraction mechanism for the target species, capable of drawing adults from significant distances. Match the pheromone lure to the specific target pest species for maximum effectiveness. Trap Placement & Interpretation Hang yellow sticky cards at plant canopy height, one card per 100-200 square feet for monitoring. Count and record captures weekly on a per-trap basis - increasing counts over consecutive weeks indicate a growing population that requires intervention; stable or declining counts indicate the current IPM program is keeping pace. Change traps when they are 25-50% covered or weekly for accurate p
