An insect net for a poly house (also known as a net house or insect-proof netting) is a protective mesh covering designed to keep insects like whiteflies, aphids, thrips, leaf miners, and moths out of greenhouse or polyhouse environments. These nets help in minimizing pest attacks, reducing the need for chemical pesticides, and ensuring better crop quality and yield. Key Features of Insect Nets: Mesh Size: Common mesh sizes: 25 mesh, 40 mesh, 50 mesh, and 60 mesh. Smaller mesh size (higher number) blocks smaller insects but may reduce airflow. Material: Made from UV-stabilized polyethylene or HDPE (High-Density Polyethylene). Durable, tear-resistant, and resistant to sunlight and weather conditions.
