How To Prevent Birds From Nesting in Unwanted Places

Preventing birds from nesting in unwanted places requires a combination of physical barriers, deterrents, and habitat modifications. Here are effective strategies to keep birds from nesting where they’re not welcome:

Physical Barriers

  1. Netting:
    • Use bird netting to cover areas like eaves, balconies, and open vents.
    • Ensure the netting is securely fastened and covers all potential entry points.
  2. Spikes:
    • Install bird spikes on ledges, beams, and other surfaces where birds like to perch.
    • Spikes make these areas uncomfortable for birds to land on.
  3. Mesh and Screens:
    • Cover chimneys, vents, and other openings with wire mesh or screens.
    • Make sure the mesh size is small enough to keep birds out.
  4. Bird Slopes:
    • Install bird slopes on ledges and flat surfaces to create a slippery incline that birds cannot land on.


  1. Decoys:
    • Place predator decoys like owls, hawks, or snakes in areas where birds are likely to nest.
    • Move the decoys regularly to maintain their effectiveness.
  2. Reflective Objects:
    • Hang reflective tape, old CDs, or aluminum foil strips around the area.
    • The reflections and movements deter birds from approaching.
  3. Sound Devices:
    • Use ultrasonic bird repellers that emit sounds unpleasant to birds but inaudible to humans.
    • Opt for devices that can be programmed to prevent birds from getting used to the noise.
  4. Wind Chimes:
    • Install wind chimes near nesting sites. The noise and movement can be effective in deterring birds.

Habitat Modification

  1. Remove Nesting Materials:
    • Regularly clear away twigs, leaves, and other materials that birds might use to build nests.
    • Keep your property clean and free of debris.
  2. Modify Landscaping:
    • Trim back trees and shrubs that are close to buildings and might provide attractive nesting sites.
    • Choose plants that are less appealing to nesting birds.
  3. Eliminate Food Sources:
    • Keep garbage cans tightly sealed.
    • Clean up food scraps and spills promptly to avoid attracting birds.

Maintenance and Monitoring

  1. Regular Inspections:
    • Frequently check for signs of nesting activity and address any potential issues immediately.
    • Inspect attics, garages, and sheds for nests.
  2. Prompt Removal:
    • If you find a nest being built, remove it before eggs are laid (ensure compliance with local wildlife laws).
    • Clean the area thoroughly to remove any scent markers.
  3. Block Return Access:
    • After removing a nest, block access to the nesting site to prevent birds from returning.
    • Repair any damage or holes in the building structure.

Legal Considerations

  1. Know the Laws:
    • Many birds are protected by laws, such as the Migratory Bird Treaty Act in the United States.
    • Check local regulations before removing or disturbing nests, especially if eggs or chicks are present.
  2. Humane Practices:
    • Always use humane methods to deter birds.
    • Avoid causing harm to birds or their nests.

By implementing these strategies, you can effectively prevent birds from nesting in unwanted areas while maintaining a respectful and humane approach to wildlife management.
