Sensor® Sticky Cards — 50 pk — Yellow — Pest Monitoring & Trapping

Yellow Monitoring Cards for Early Pest Detection

Flying pests like winged aphids, thrips, and fungus gnats often go unnoticed until a population is already established and harder to manage. BASF Sensor Sticky Cards use bright yellow color to attract these pests and a non-drip Posi-Trap glue to hold them, giving growers a simple early-warning system placed directly in the grow space.

This pack includes 50 cards, enough to establish a monitoring grid across multiple rooms, rows, or benches and replace cards on a regular schedule as they fill.

Key Features & Benefits

• Non-drip Posi-Trap glue — stays tacky for effective trapping without dripping onto plants or hands.
• Bright yellow attractant color — draws winged aphids, leafminer adults, thrips, whiteflies, fungus gnat adults, shore flies, fruit flies, and leafhoppers.
• Non-sticky card edges — easier to handle and place without cards sticking together in storage.
• 50-count pack — enough cards to build a monitoring grid across several rooms or benches.
• Simple visual monitoring — catch counts show which pests are present before an infestation becomes visible on foliage.

Who Should Use This

Growers running an integrated pest management program who want an early-warning system for flying pests, and anyone monitoring for winged aphids, thrips, whiteflies, or fungus gnats across a cultivation space, are the direct fit for these cards.

Frequently Asked Questions

How many cards do I need for my grow space?

BASF recommends roughly 1 card per 500 square feet as a general monitoring density. Larger or higher-risk spaces may benefit from a denser placement grid.

Where should I place these cards?

Placement depends on the target pest: cards for winged aphids, leafminers, whiteflies, and fungus gnat adults are typically hung just above the canopy, while cards for shore flies and fungus gnats can also be placed near the soil or media surface. Check activity on a regular schedule and adjust placement as the canopy grows.

How often should I replace the cards?

Replace cards once they are heavily covered with insects and debris, or on a routine schedule such as weekly, whichever comes first. A fully saturated card loses its effectiveness at catching additional pests.

Do these cards control an existing infestation on their own?

Sticky cards are a monitoring and light-trapping tool, not a standalone control method for an established infestation. Use catch counts to inform a broader integrated pest management plan rather than relying on cards alone.
