Bird spikes, also known as bird chasing spikes,are a device used to prevent bird nuisance and damage to buildings, facilities or crops. They are usually made of plastic or stainless steel, have sharp and pointed tips, and are secured to surfaces that are subject to bird nuisance, creating a barrier that is unsuitable for bird retention. The design and arrangement of anti bird spikes is based on the behavioural and physical characteristics of birds. They are placed on beams, roof edges, window sills, signs, vents, and other areas that are prone to bird retention. Birds attempting to linger or build nests on these surfaces feel the sharp tips of the bird spikes and choose to leave or look elsewhere. The application of bird spikes offers several advantages. Firstly, they are a humane, harmless and environmentally friendly solution. In contrast to the use of chemicals or pesticides, plastic bird spikes do not cause any harm to birds and simply protect the area by defining boundaries and barriers. Secondly, bird spikes are simple and easy to install and can be adapted to various surfaces and building structures. Moreover, bird spikes are made of highly weather-resistant materials that can withstand a wide range of climatic conditions and environmental influences for a long service life. The use of bird spikes can help people to maintain a tidy, safe and welcoming environment whilst protecting and preserving the balance of harmonious co-existence with birds.
