Green-tek No-Thrip Insect Screen - 75 Mesh - 0.18mm x 0.25mm - Sold by the Square Foot

Green-tek No-Thrip Insect Screen - 75 Mesh - 0.18mm x 0.25mm - By the Square Foot

Green-tek No-Thrip Insect Screen provides an effective physical barrier against the most damaging common greenhouse pests - including thrips, whiteflies, and aphids - without compromising airflow or light transmission. Constructed with high-tensile, round polyethylene filaments in a 75-mesh, 0.18mm x 0.25mm opening configuration, this UV-stabilized screen is rated for 5 years of durability. Lightweight and transparent, it installs easily on greenhouse vents, side walls, and openings to reduce pesticide use and support healthier crop production.

Key Features & Benefits

• 75 mesh with 0.18mm x 0.25mm openings: Fine mesh dimensions exclude thrips, whiteflies, and aphids - the three most prevalent flying insect pests in greenhouse production - while maintaining good airflow.
• 5-year UV-stabilized durability: UV-resistant polyethylene filaments resist degradation from solar exposure for multi-year service in permanent vent and wall screen installations.
• High-tensile round filaments: Circular filament cross-section minimizes wind resistance and airflow restriction compared to flat-weave alternatives.
• Lightweight and transparent: Minimal visual obstruction and light reduction - maintains greenhouse light levels while providing complete insect exclusion.
• Reduces pesticide use: Physical exclusion of key pest vectors reduces the frequency and volume of insecticide applications needed for effective IPM.
• Sold by the square foot: Order precisely the coverage area needed for your vent and opening dimensions.

Who Should Use This

No-Thrip screen is essential for commercial greenhouse operators who want to exclude flying insect pests from their growing environment as the first line of integrated pest management. It is particularly valuable for operations where thrips, whitefly, and aphid pressure is persistent and costly to manage with pesticides alone - and for organic growers who want to minimize or eliminate chemical interventions.

Compatibility

Suitable for installation on greenhouse side vents, ridge vents, intake louvers, and any other openings where insect entry is a concern. Can be attached using standard greenhouse screen attachment systems, Green-tek Shark Bite Gripper Fasteners, or Clip-It style fasteners. Sold by the square foot - contact your supplier for roll widths and minimum order quantities.

Frequently Asked Questions

Does this screen actually stop thrips?

Yes. Thrips are extremely small insects (approximately 1mm long) that can pass through many standard insect screens. The No-Thrip screen's 0.18mm x 0.25mm opening size is specifically calibrated to physically exclude western flower thrips and other common thrip species, making it one of the most effective physical exclusion options available for this pest.

Does fine mesh screening reduce airflow significantly?

Fine mesh screens do reduce airflow compared to unscreened openings. The round filament design minimizes this restriction compared to flat-weave mesh, but increasing vent area by 25-50% when installing 75-mesh screen is generally recommended to compensate for the reduced ventilation efficiency per square foot of opening.

How long does No-Thrip screen last?

Green-tek No-Thrip is UV-stabilized for a rated service life of 5 years under continuous outdoor sun exposure. Regular cleaning with low-pressure water spray to remove dust and pollen buildup will help maintain airflow capacity and extend effective service life.

Can No-Thrip screen be used as a side wall covering?

Yes. No-Thrip is commonly used as a complete side wall covering for open-sided greenhouse structures where maximum ventilation is needed while maintaining insect exclusion. The transparency and lightweight construction make it practical for large-area wall applications without significant structural loading.
