Product Description
The Science of Physical Pest Exclusion
In modern Kenyan agriculture, relying solely on chemical sprays is increasingly expensive and less effective due to growing pest resistance. Our Insect Nets provide a mechanical solution by physically blocking pests before they reach your crop.
By installing these as side-venting or as a complete enclosure, you create a "clean zone" that drastically reduces the incidence of viral diseases spread by insects. The white monofilament material provides a secondary benefit by reflecting UV rays. This disorients the visual navigation systems of incoming pests and discourages them from landing on the structure.
Aperture vs. Thorax: Choosing Your Mesh Size
Insect exclusion is a precise physics problem. A net only works if the aperture (hole size) is smaller than the thorax (chest) of the target insect. Selecting the correct mesh is a balance between pest protection and greenhouse ventilation.
-
40 Mesh ($400\mu m$ aperture): The industry standard for blocking larger pests like Aphids, Leafminers, and Moths while allowing for maximum airflow.
-
50 Mesh ($290\mu m$ aperture): Specifically designed to block smaller, high-risk pests like Whiteflies.
-
75 Mesh ($150\text{--}190\mu m$ aperture): The fine grade required to exclude Thrips, the smallest and most difficult greenhouse pests.
Because finer nets like the 75 mesh can reduce airflow by up to 50%, ensure your greenhouse has adequate height or a larger vent surface area to prevent internal heat stress.
Optical Barriers and PAR Transmission
White (Crystal) insect nets are engineered for high PAR (Photosynthetically Active Radiation) transmission. This ensures that the specific wavelengths of light your plants need for growth pass through the mesh unimpeded.
Simultaneously, the monofilament reflects light in the $300\text{--}400\text{ nm}$ (UV) range. This is the specific spectrum that many insects use for navigation. By reflecting this light, the net effectively "blinds" or disorients pests, making the greenhouse structure significantly harder for them to locate from a distance.
Durability and Installation Integrity
Cheaper nets often suffer from photo-oxidation, becoming brittle and dusty within a year. Our nets are chemically treated with UV stabilizers to withstand the intense solar radiation of equatorial regions.
For the best results, the net must be installed tightly using wiggle wires or clips. Pests are highly opportunistic; even a small wrinkle or a loose edge can serve as an entry point for a swarm. Regular inspections for small tears are recommended to maintain the integrity of your pest-proof environment.

Note on 75-Mesh Protection: Due to the specialized manufacturing process and the significant impact on greenhouse ventilation, our 75-mesh (Thrips-grade) netting is available upon request. Please contact our technical team for a consultation to ensure your greenhouse structure can support the required airflow for this density.
