Birds 4

Metal buildings are a popular choice for many businesses, warehouses, and even homes due to their durability, flexibility, and cost-effectiveness. However, these structures often attract unwanted guests – birds. From pigeons, starlings, and house sparrows to larger birds like eagles and hawks, these feathered creatures can cause several problems, including corrosion, disease transmission, gutter blockages, and damage to machinery. This article provides a comprehensive guide on how to keep birds out of metal buildings, with a focus on humane and effective solutions.


Keeping birds out of metal buildings can be achieved by using a combination of physical barriers, visual deterrents, and bird exclusion products. Install bird netting and spikes to prevent birds from entering or nesting in the building. Use mirrors or foil tape strips to create reflective surfaces that deter birds. Apply bird repellents on surfaces where birds are likely to land or nest. Additionally, consider hiring professional bird control services for a comprehensive solution. Always ensure to use humane methods and comply with local regulations on bird control.

Common Bird Species in Metal Buildings

The most common birds that tend to nest in metal buildings include pigeons, starlings, house sparrows, and gulls. These birds often find sheltered ledges, signage, air conditioning units, and other nooks and crannies in buildings to build their nests. In some cases, larger birds like eagles, hawks, and vultures may also nest in metal buildings, causing damage to the structure.

Why Birds Nest in Metal Buildings

Birds choose to nest in metal buildings for several reasons. Firstly, these structures provide shelter and protection from harsh weather conditions and predators. Secondly, some metal buildings generate warmth from electrical components, making them attractive nesting sites. Thirdly, buildings in urban or commercial areas may inadvertently provide food and water sources, attracting birds to nest nearby. Lastly, the design of some metal buildings may inadvertently provide ample space for birds to perch and build nests.

Problems Caused by Birds in Metal Buildings

Birds in metal buildings can cause a myriad of problems. Their acidic droppings can corrode metal, paintwork, and other building materials, weakening the structural integrity of the building. Birds can also carry diseases like Avian Flu, posing a health risk to people working in or around the building. Nesting birds can cause blockages in gutters and drainage systems, leading to water damage and potential structural issues. Birds can also damage machinery and equipment housed within the metal building.

Effective Methods to Prevent Birds from Entering Metal Buildings

To prevent birds from entering metal buildings, you can use a combination of physical barriers, visual deterrents, and bird exclusion products. Here are some of the most effective methods:

  1. Bird Netting: Install heavy-duty bird netting to create a physical barrier that prevents birds from entering or nesting in the building. Bird netting is available in various mesh sizes and can be customized to fit your specific needs.
  2. Bird Spikes: Install stainless steel or plastic bird spikes on ledges, gutters, window sills, and other areas where birds may land or perch. Bird spikes are humane and effectively prevent birds from landing on surfaces without causing harm.
  3. Reflective Surfaces: Use mirrors or foil tape strips to create reflective surfaces that deter birds from entering the building. Birds can be kept away by the effect of reflective surfaces, which serve as a decoy.
  4. Bird Wire: Install bird wire on building ledges and other areas where birds may land or perch. Bird wire is a discreet and effective method to prevent birds from landing on surfaces.
  5. Bird Repellents: Use bird repellents, such as aromatic bird repellent gels or sprays, to deter birds from entering the building. These products can be applied to surfaces where birds are likely to land or nest.

Natural Ways to Repel Birds from a Metal Building

There are several natural ways to repel birds from a metal building, including using shiny objects, visual deterrents, bird netting, bird spikes, peppermint oil, and motion-activated repellents.

Remember to check local regulations and laws regarding bird control, as some species may be protected. Always opt for humane and non-harmful methods to deter birds from your property. By implementing these precautions, you can effectively prevent birds from entering metal buildings while ensuring their safety.

In conclusion, keeping birds out of metal buildings requires a combination of effective strategies, regular maintenance, and in some cases, professional help. By understanding the behavior of birds and implementing the right deterrent methods, you can keep your metal building bird-free, ensuring its longevity and functionality.
