Many buyers mistakenly believe that the denser the mesh, the better. However, scientific research shows that suitable insect net is not necessarily the finest mesh, but rather the coarsest mesh that effectively blocks target pests while maximizing internal ventilation.
When purchasing insect net, "mesh count" refers to the number of openings per inch. As mesh density increases, the mesh size decreases, which affects greenhouse air quality in two ways:
Impaired airflow: Using ultra-fine mesh reduces cross-ventilation by 15% to 35%. Reduced ventilation and increased humidity create favorable conditions for fungal outbreaks such as powdery mildew.
Changes in light transmittance: High-quality plain-woven virgin high-density polyethylene (HDPE) insect net provides optimal shading. However, overly dense mesh can alter light diffusion, so this should be considered when choosing insect net for sun-sensitive fruits and vegetables or ornamental nurseries.
To reduce inventory and maximize profits, savvy wholesale buyers should select the best-matched insect net based on the characteristics of the pests. Based on 17+ years of manufacturing and export experience, SUGRAND has categorized insect net sizes as follows:
Mesh Count | Hole Diameter | Best For Blocking | Typical Application |
16×16 mesh | ~1.2 mm | Large insects: beetles, grasshoppers, locusts | Orchards, field crops with high airflow needs |
25×25 mesh | ~1.0 mm | Moths, caterpillars, larger flies | Vegetable farming, general crop protection |
32×32 mesh | ~0.8 mm | Medium insects: leafminers, fruit flies | Greenhouses, commercial vegetable production |
40×40 mesh | ~0.6 mm | Small insects: aphids, whiteflies | High-value crops, tomato and pepper greenhouses |
50×25 mesh | ~0.5 mm | Fine insects: thrips, small aphids | Maximum protection for sensitive crops |
60–80 mesh | ~0.3–0.5 mm | Very tiny insects: thrips, spider mites | Specialty crops, research applications |
The material of the insect net affects the product's durability and the supplier's reputation. Insect net made from recycled materials will degrade due to solar radiation after only 8-12 months, leading to customer disputes and damaging brand reputation.
At SUGRAND, we use 100% new high-density polyethylene material with added UV-resistant additives, ensuring our insect net has a lifespan of up to 5 years. Using advanced Sulzer weaving technology, we guarantee the stability and tear resistance of the net, preventing it from expanding or deforming even on arched greenhouse frames.
By bypassing middlemen and leveraging high-quality, certified insect net to improve profit margins, SUGRAND offers complete ODM & OEM production capabilities, with seamless widths ranging from 0.5 meters to 5 meters, and provides customized private-label packaging and international export logistics services.
