Problems Caused by Bird Nests and Preventive Measures for Commercial Buildings

Naturally seeing birds’ nests at parks are natural and charming. It gives us the idea of new life is coming and that they will soon help our Eco-system. However, when birds’ nests are found in light fixtures at home, working spaces, outer walls, vents like dryer, bathroom exhausts, and even kitchen stoves, then they become a nuisance. Swallows, pigeons, gulls, sparrows, starling, and many others are just some of the birds that even commercial buildings are having a hard time dealing with.

Problems Caused by Birds in Commercial Buildings

1. Creating noise. Although it is natural for them to tweet whenever they want, but when they gather in sizeable numbers and tweet in harmony, well that can be a nuisance to building occupants and its workers and may even hinder customers from coming back.

2. Creating nests. These nests although essential to their survival can bring nuisance as it brings:

Roof damage – starling, pigeon, and sparrow nests can be commonly found in rain gutters, drains and the underside of roof corners. When drainage systems are blocked and standing water is forced to rise, this can result to collapsed roofs. A collapse roof can bring a lot of damage not only to the roof itself, but for those who are inside the structure. This could ultimately put a company in danger and out of business.

Blocked ventilation system – When ventilation systems are blocked this can cause problems since this will spread diseases as it will actually block the airflow through the building. The worst thing that could happen in this situation is carbon monoxide poisoning.

Can cause fires – Bird nests, twigs, straw, and dried droppings are all flammable. Nests that are found in electrical openings such as light fixtures and machinery can cause serious fire risk.

Bird droppings – Bird droppings can cause disease, property damage, roof damage, machinery damage, faded paint finishes, and creates bad company image.


Preventing Bird Nests at Commercial Buildings

Birds are mostly protected under the Migratory Bird Treaty Act of 1918. This means that any migratory bird is illegal to intentionally kill, injure or take. It is illegal to intentionally damage or destroy their nests, eggs, or young while it is being built or in use. The Act allows fines or even imprisonment for every bird, egg or nest that are destroyed. Because of this law, companies are also finding ways to stop birds from nesting before they even come to their premises.

Bird Roosting Deterrents

Porcupine wire or bird spikes. These deterrents are inexpensive and easy to install. They are also made simple and yet effective as a bird control device. Another benefit to porcupine wire strips is its thin, stainless-steel wires that are invisible at the distances from which structures are usually viewed. The coat of weathering also makes installations inconspicuous that makes this system a popular choice for many well-known landmarks and historical restorations.

Post and wire systems. This system creates an unstable landing place for pigeons and larger birds. This is mostly suitable on parapet walls and ledges that can help in keeping the pigeons and larger birds off.

Bird coils. This deterrent comes in 4” or 6” and look like a slinky stretched out placed on the parapet wall. When pigeons land on the wall and touch the coils, it creates an unstable surface by folding over under the birds weight, thus scaring off the bird.

Bird netting. If you have an open warehouse, a building, or an overhang where birds can be seen flying into the rafters and beams, installing bird netting is an effective and at the same time economical way since this will stop birds from coming in. Installation of this deterrent may be very simple while others may require the need of an experienced contractor.  Nettings are commonly attached to a cable system to hold the net into place. Net sized vary from ¾” for sparrows and swallows, 1 1/8” for starling and blackbirds, and 2” for pigeons and large birds.

Safe chemical bird repellents. Always look for safe chemical bird repellents that are regulated by the U.S. EPA under FIFRA. A bird that is exposed to a safe fogging bird repellent will experience a temporary pain stimulus that will irritate a nerve in their mucus membrane. This will not cause any damage to the bird, but this will signal them that the place they experienced the pain is not safe and undesirable.

Sticky paste or gels. These compound tends to irritate birds as it works by spreading a non-drying, nontoxic substance on the surface of the area where you do not want birds to land. Once the birds land on the surface they will feel the sticky gel and leave the protected area.

Planning the Right Deterrent

Once you have planned the most effective deterrent or combination of products to be used, decide if you want to have someone install it for you, or do it yourself. However, a qualified contractor will be able to estimate the needed materials much easier especially in companies where they have to do everything right and in proper order while still considering the welfare of the birds.
