Recommended netting specification
HDPE is the recommended material. Mesh size follows the size of the target species:
| Size class | Typical species | Recommended mesh |
|---|---|---|
| Small birds | Sparrow, bulbul | 1.5 cm × 1.5 cm to 2 cm × 2 cm |
| Medium birds | Myna, drongo, dove | 3 cm × 3 cm to 4 cm × 4 cm |
| Large birds | Pigeon, night heron | 4 cm × 4 cm to 7 cm × 7 cm |
Final mesh and twine diameter still depend on the site, the installation method and the required service life. Send us photographs and dimensions and we will help you specify.
