Anti-bird nets, also known as bird netting, are physical barriers used to prevent birds from accessing specific areas. These nets are typically made of lightweight plastic or nylon mesh and are installed over buildings, crops, and other structures to deter birds from roosting, nesting, or feeding there. The mesh size is small enough to prevent birds from passing through, effectively creating a protective enclosure. While anti-bird nets can be an effective solution for managing bird-related issues, their use raises concerns about potential harm to birds if not installed or maintained properly.
