Insect netting sized to the pest, not to the catalogue

Insect & fruit-fly netting

Screens fine enough to stop the pest, open enough to keep the crop cool

Insect netting is a physical barrier: instead of spraying, you keep the insect outside. The engineering problem is that the aperture small enough to exclude thrips is also small enough to throttle airflow, so the specification has to match the pest, the crop and the climate.

We weave three weights — 45 g/m² for fruit fly, leaf miner and larger insects; 90 g/m² for whitefly and aphid; and 103 g/m² for thrips and other very small pests. All three are HDPE, HALS stabilised, and available in white, transparent and black, with hemmed and eyeleted edges for tunnel or vent mounting.

For outdoor vegetable crops the same fabric is used as a floating cover over hoops — it keeps cabbage white, flea beetle and birds off without chemical treatment, and it holds a degree of warmth at night.

Greenhouse vents and side walls

Screens are fixed over roof vents and side openings with aluminium profiles or cable. Sealing the structure matters as much as the mesh: a 1 cm gap around a door defeats a 40-mesh screen.

Seed and herb production

Where cross-pollination or seed purity matters, insect net also excludes pollinators — the same barrier works in reverse when you introduce bumblebees inside.

Orchards and vineyards

Fruit-fly screens are draped as side nets around ripening blocks, usually combined with bait stations. The net also reduces bird damage and sunburn on exposed fruit.

Organic and residue-free programmes

Physical exclusion is the backbone of organic pest control and of export programmes with strict maximum residue limits, where one rejected container outweighs the whole netting budget.
