80-Mesh Insect Net Blocks Thrips & Mites | UV-Stable

If you’ve been fighting thrips and mites in greenhouses or net-houses, you’ve probably heard the quiet buzz around 80-mesh insect net: Suitable for preventing tiny pests such as thrips and mites. Lately, many growers tell me they’re cutting pesticide sprays and still improving pack-out. Honestly, that sounded optimistic—until I started visiting fields using this spec.

Industry trend check: controlled-environment agriculture is tightening screens, shifting from 40–50 mesh to 70–80 mesh for high-pressure pest seasons. The trade-off is airflow, but design tweaks (larger vent area, forced fans) are compensating. Surprisingly, the ROI math still works once you count reduced virus transmission from thrips.

Fast specs (real-world values)

How it’s made (quick process flow)

• Materials: HDPE virgin resin + UV masterbatch; optional anti-dust/slip additives.
• Method: precision monofilament extrusion, leno/warp knitting at 80-mesh; heat setting for dimensional stability.
• Edges: reinforced selvedge; optional eyelets; color tracers for QC.
• Testing: mesh count per ASTM D3775; tensile per ISO 13934-1/ASTM D5035; air permeability ISO 9237; UV aging ISO 4892-2/ASTM G154; photo-transmittance lab panels.
• Service life: around 3–5 seasons depending on UV index, cleaning, and tensioning.
• Certifications: typical lots carry ISO 9001 QMS; third-party SGS/Intertek reports; REACH/RoHS substance compliance.

Where it shines

Greenhouse vents, insect-proof doors, nurseries, salad greens, peppers, tomatoes, berries, and seed production. The tiny aperture targets Western flower thrips and two-spotted spider mites; it also curbs whiteflies and aphids. Integrates well with IPM—less virus ingress, fewer emergency sprays, steadier biologicals.

Real-world case (field note)

In Shandong, a pepper grower swapped 50-mesh for 80-mesh insect net: Suitable for preventing tiny pests such as thrips and mites. on windward vents. Over eight weeks, sticky-card thrips counts dropped ≈42% and viral symptoms declined; yield bumped ≈12%. Fan runtime rose ~8% to compensate airflow—still penciled out thanks to fewer pesticide passes and cleaner fruit. I’ve heard similar stories from hydroponic lettuce (albeit with more attention to humidity).

Vendor snapshot (what to compare)

Customization & ordering

Options include widths up to ≈5.2 m, roll lengths 50–200 m, white/transparent or black-tracer yarns, reinforced edges, zipper-door panels, and pre-cut vent kits. For high-wind sites, ask for heavier denier yarn (you’ll trade a bit of light transmission).

Installation tips

• Increase vent area or fan capacity by ≈15–25% to offset airflow loss.
• Keep nets taut; seal edges; bury skirts 15–20 cm to block crawlers.
• Wash dust periodically; UV life improves when clean.
• Pair with sticky cards and scouting—netting is one pillar of IPM.

Bottom line: for thrips and mites, 80-mesh insect net: Suitable for preventing tiny pests such as thrips and mites. balances exclusion with workable airflow. It’s a factory-sale HDPE anti insect net with UV resistance and the kind of consistency serious growers look for. If you’re speccing a retrofit, run a quick airflow calc, then pull the trigger before peak pest pressure.
