Blue Sticky Traps Built for Thrips Scouting
Western flower thrips are drawn to blue more than to any other colour, and that response is what these boards are built around. Each pack holds ten blue glue boards, each one 10 x 25 cm, the Euro standard size. A peel-off liner covers a high-tack, non-toxic adhesive until the board goes up. Aphids, whiteflies, fungus gnats, fruit flies and leaf miner flies stick to the same surface. The boards are UV-stable and unaffected by sprinkler systems, so they hold up in warm greenhouses and under overhead irrigation. For routine monitoring, the rate is one board per 200 m², checked and counted every week. Mass trapping raises that to one board per 20 m², with extra boards clustered on hot spots. Hang each board upright with its lower edge about 10 cm above the crop. Replace it after 6 to 8 weeks, or sooner once the glue is crowded. The boards also stick flat to a pot or container where pests gather.
Hanging Sticky Cards for Thrips Where They Fly
Thrips are weak fliers that travel low and in short hops. Boards set just above the tops of the plants catch far more of them than boards hung high in the room. Start along the walls, near doors and intake vents, where new adults drift in. Raise each board as the canopy climbs, so it stays in the flight path. Under misting, catches drop because wet thrips do not fly well, so a quiet board there proves little. Keep blue boards out of rooms using bumblebees for pollination, because bees head for blue too. Pull them for a day or two after releasing winged parasitoids. A hand lens at ten to fifteen power separates thrips from gnats and shore flies. Record the count on each board on the same day every week. That log shows whether a spray or a predator release actually changed anything.
Key Features
- Ten Boards Per Pack: Enough for a perimeter line of monitoring stations, with spares for the mid-cycle change.
- Thrips-Attractive Blue: Western flower thrips respond to this shade, so early adults show up here first.
- Peel-Off Liner: The high-tack glue stays clean in storage and goes live only when the liner comes off.
- UV-Stable, Sprinkler-Proof: Boards keep working under greenhouse light, heat and overhead irrigation.
- Monitoring or Mass Trapping: Run them as a sparse warning grid or a dense trap line around a hot spot.
