Birds Nesting in Attic Vents: Exclusion with Hardware Cloth

Birds entering 2-inch diameter attic vents with 30-year-old screens. Asks for outside covering to replace screens.

Expert Solution

1. Identify species—only pigeons, house sparrows, starlings are unprotected; others need federal permit.
2. Install 1/4-inch hardware cloth over vents—stops birds and bats.
3. Ensure birds are out before sealing. Secure with screws/washers, seal for water tightness. Paint to blend. Note: reduces airflow. Watch power lines.
