Yellow Sticky Traps With a Counting Grid
Most flying pests show up on a yellow board days before damage shows on a leaf, which is why scouting starts here. These are flat yellow glue boards, 10 x 25 cm each, packed ten to a pack. A printed grid on the face turns each weekly check into a number you can log. A peel-off liner protects the high-tack adhesive until the board goes up. Aphids, whiteflies and leaf miner moths take this yellow for fresh growth and land on it. Thrips, fungus gnats, fruit flies and leaf miner flies turn up on the same surface. The colour is tuned to raise pest catch while drawing in fewer beneficial insects. For monitoring, use one board per 200 m² from the start of the crop. For mass trapping, go to one board per 20 m², adding extra boards around hot spots. Hang each one upright, with its base about 10 cm above the canopy. Swap boards every 6 to 8 weeks, or sooner once the glue fills up.
Reading Sticky Traps for Aphids and Whiteflies
One board says little, but a row of them read on the same day each week shows where pressure is building. Start near doors and intake vents, because winged aphids and whiteflies arrive on outside air. Count the grid squares and write the totals down. A jump from one week to the next appears on the board before it shows on the leaves. Fungus gnats are the exception to upright hanging. Lay a board flat just above the media, and adults hatching from wet substrate will find it. Dust, pollen and leaf litter dull the glue, so a dirty room uses boards faster. Pull boards for a day or two after releasing parasitic wasps, since yellow catches those too. Thrips land here as well, but counts run low, so a quiet board is not proof the room is clear. Handle each board by its edges, because glue on a glove ends up on the next leaf.
Key Features
- Printed Counting Grid: Turns a weekly glance into a count you can log and compare.
- Ten Boards Per Pack: Covers several monitoring stations with spares left for a mid-cycle swap.
- Peel-Off Liner: The glue stays clean in storage and goes live only at hanging time.
- Broad Yellow Attraction: Pulls in aphids, whiteflies and leaf miners, plus gnats and fruit flies.
- Monitoring or Mass Trapping: Works as a light early-warning station or a dense trap line on a hot spot.
