Bug Scan Yellow 10pcs (25x10cm)

Ten yellow sticky traps, 25 by 10 centimetres. They catch whitefly, leafminer, fungus gnat and aphid, all four of which are drawn to yellow. But their real value is not in what they catch, since those numbers are far too small to stop an infestation. It is in what they tell you.

A trap is a measuring instrument

Flying pests only become visible in a crop once there are already plenty. On a yellow trap you see the first ones. Hang them at the start of the cycle, just above the canopy, and you have a system watching for you continuously while you are not there.

It is about repeated counting, not about hanging and forgetting. Walk them once or twice a week and note what you see. One fungus gnat means nothing. Three this week after none last week means something is starting. That is precisely the moment when intervening is still small and cheap.

Where to hang them

Just above the canopy and at the point where air comes in, because that is where flying insects arrive first. Hang several, spread out: one trap in a corner tells you about that corner. If your canopy moves or grows, move the trap with it, or eventually you are measuring the air above your plants.

Replace a trap once the surface is full or dusty. Touch it: if it no longer sticks, it no longer measures.

Yellow does not cover everything

Thrips is the exception: it is not drawn to yellow but to blue. So anyone wanting early warning of thrips needs blue traps alongside these. In practice many people hang both colours so there is no blind spot in the measurement.

Frequently asked questions

Will a trap solve my infestation? No. The numbers you catch are too small to stop a population. They tell you when to act.

How often should I check? Once or twice a week, and note the numbers. The change between two counts is the signal, not the number itself.

Where do I hang them? Just above the canopy and near where air enters. Spread several rather than using one.

Will these catch thrips? Barely. Thrips responds to blue; that is what the blue traps are for.
