Greenhouse Insect Net

VIDEO OF INSECT NET

    A greenhouse insect net is a specially woven or knitted mesh made from synthetic or eco-friendly threads that blocks insects from entering your greenhouse. Think of it as your garden’s high-tech mosquito net.

    Material Composition     

Polyethylene (PE)    

Most high-quality insect nets are made from polyethylene. It’s strong, flexible, and stands up to the elements. Plus, it’s lightweight enough to allow proper ventilation without sagging under its own weight.

Polypropylene (PP)     

Another common option. It’s a bit stiffer than PE but very durable. PP nets are often preferred in areas with high heat due to their excellent thermal resistance.

High-density polyethylene (HDPE)    

High tensile strength, abrasion resistance, UV resistance is better than ordinary PE net, suitable for long-term use.

Polyester fiber (PET)

High strength, high temperature resistance, excellent anti-aging performance, service life can reach more than 5 years.

UV Stabilizers and Additives    

Since greenhouses are sun-drenched environments, the netting has to withstand constant UV exposure. That’s where UV stabilizers come in—they prevent the material from breaking down and turning brittle.

Eco-Friendly Options Emerging    

With sustainability becoming non-negotiable, some companies are rolling out biodegradable insect nets made from plant-based polymers. These are ideal for organic-certified farms and eco-conscious growers.

  Production Process of Insect Nets      

       

Extrusion of Threads        

It all starts by melting plastic resin into a liquid and pushing it through tiny holes to create filaments. These become the warp and weft of the net.

Weaving or Knitting Process        

These filaments are then woven or knitted into a mesh pattern. Weaving offers more strength, while knitting gives more flexibility. The choice depends on your specific needs.

Heat Setting and UV Treatment        

The mesh gets heat-treated to lock in its shape and then treated with UV stabilizers to improve lifespan and durability.

Cutting and Packaging        

The nets are cut to standard or custom sizes and rolled up for delivery. Some come with reinforced edges and eyelets for easy installation.

  Key Functions of Insect Nets      

   

Pest Exclusion and Barrier Creation    

Let’s cut to the chase—this is the #1 job of an insect net. It forms a physical barrier that stops pests cold. No holes, no shortcuts.

Microclimate Regulation    

Because the mesh slows down airflow slightly, it can help maintain a more stable microclimate inside. Less wind means less evaporation and temperature swings.

Improved Pollination Management    

With pollinators controlled (or even introduced intentionally), you get better fruit set and quality. No more worrying about bees flying away or pests sneaking in.

Reduced Pesticide Dependency    

When pests can’t get in, there’s less need to spray. That means healthier produce and happier consumers.

  How to Choose the Right Insect Net      

1、Match the Mesh with the Pest    

Always start with the pest. Know your enemy. Tiny thrips? Go for a 50-mesh. Big beetles? 25-mesh will do.

1）25 Mesh – For Larger Pests

This one keeps out beetles, grasshoppers, and big flying insects. Great for basic protection.

2）40 Mesh – For Mid-Sized Insect

Think aphids and leafminers. 40 mesh is a sweet spot for airflow and pest control.

3）50+ Mesh – For Whiteflies and Thrips

These ultra-fine nets stop even the tiniest pests. Essential for crops like peppers, tomatoes, and herbs.

2、Consider Airflow and Climate Needs

Finer mesh means less airflow. In hot areas, balance pest control with ventilation to avoid overheating.

1）Windy areas → Choose HDPE or PET high strength insect screens.

2）High temperature and strong sunshine areas → choose UV coated insect screens.

3、Durability and UV Resistance

Check the UV rating and expected lifespan. Cheaper nets often break down in a season or two.

Short-term planting → PE insect screens (1-2 years)

Long-term use → HDPE or PET insect nets (3-5 years)

   Application Scenarios   

Our greenhouse insect net is versatile and suitable for a wide range of agricultural and horticultural settings.

Fruit Growers in 

 farmers saw a yield increase and  pesticide reduction after installing insect nets.

Organic Farms 

These growers use fine mesh nets to protect lettuce and herbs—selling pesticide-free produce at a premium.

High-Tech Greenhouses

Fully netted and sensor-equipped greenhouses have become the gold standard for sustainable growing.

Greenhouse insect nets are more than just a barrier—they're a breakthrough. They offer precision protection, reduce chemical dependency, and support sustainable farming. Whether you’re growing tomatoes in a backyard hoop house or running a commercial greenhouse, insect nets should be part of your toolkit. With the right net in place, you’re not just fighting pests—you’re future-proofing your harvest.

  FAQS FOR GREENHOUSE INSECT NET  

1. What's the lifespan of an insect net?

Most quality insect nets last between 3 to 5 years, depending on UV exposure and maintenance.

2. Can it fully eliminate pests?

While no method is 100% foolproof, insect nets drastically reduce pest entry and infestations.

3. Are these nets recyclable?

Yes, most polyethylene and polypropylene nets can be recycled.

4. How often should I clean the nets?

Every few weeks, especially during dusty seasons or high pollen times.

5. Do insect nets lower greenhouse temperature?

They can slightly reduce temperatures by blocking harsh sunlight, which can help in hot climates.

6. What's the ideal mesh for whiteflies?

50 to 60 mesh is perfect for keeping out whiteflies without hurting airflow too much.
