Bird Repelling Spikes and Their Uses

Bird Spikes are clusters of metal or plastic rods that are found installed in the eaves of tall buildings and other tall structures, such as bridges and walkways, that span the overhead areas of public spaces. Resembling patches of metal grass, bird spikes are designed to prevent birds from nesting in locations where they are installed. Bird spikes don't actually cause harm to birds in most cases, as the tips of the spikes are tapered and meant to annoy and drive off but not to impale, but they do make it impossible for birds to get comfortable enough to roost and design more permanent places to live. Many businesses and office buildings find it important to install this form of bird deterrent to ensure that defecation does not become a problem in well-trafficked areas.

Bird spikes are also used by airports to reduce and repel resident bird populations. Far more than being a nuisance in this specific case, birds coming into contact with airplanes that are either taking off or landing can cause serious immediate damage. Known as "bird strike", contact between birds and aircraft at altitude can shatter windshields, obstructing pilots' vision, or can even cripple jet engines if they are sucked into them. For these reasons, bird spikes are one of the bird repellent methods used by airports to prevent birds from nesting and reproducing in areas around the tarmacs.

Bird spikes come in many different varieties and sizes to suit various applications. Larger bird species are deterred by larger spikes, so this deterrent can be tailored to specific species of birds that are creating a nuisance in a particular area. Additionally, spikes are available in different materials. Metals are initially more sturdy and resistant to pressures that might warp their shape, but they will eventually rust if not initially coated with protectant or given regular maintenance. Plastic bird spikes will not rust but can eventually snap under consistent pressure from high winds and wildly fluctuating temperatures which cause the plastic to expand and contract repeatedly, weakening its integrity over time. Some spikes feature elongated central spikes supported by a lower nest of shorter spikes to make nesting practically impossible. All the same, there are some daring or dense bird species that will continue their nesting behaviors, undeterred by the bird spikes, and in fact use them as the structural pillars for their now metal-reinforced nests. This is why other forms of bird deterrent are often used in conjunction in order to increase the overall chances of success.

If you have a bird nuisance problem that you are trying to solve, consider putting the time and effort into identifying the exact species responsible for the disruption. Learning the migratory and dietary habits of the species of bird you are trying to repel will go a long way and make a great contribution to your overall success, especially since some methods of bird repellent are successful against certain species but not against others.
