- Heavy-Pressure: sites which are characterised by lots of fouling, nesting materials and even eggs. They are sheltered and are used by birds nesting at night. Netting is perhaps the most effective deterrent for such areas, however other systems such as heavy duty point point systems, the electrical track and optical gel systems could also be considered but in some cases may need to be supported by a local cull or remove persistent individual birds.
- Medium-Pressure: areas are less sheltered but still heavily fouled. They are favoured daytime perching areas overlooking a food source, netting, electric track, optical gel and spike systems may be appropriate in these areas. However, birds are likely to be displaced to adjacent sites.
- Low-Pressure: areas are exposed, occasional perching places with little fouling. Any proofing system can be used including post and wire, spikes, electrical track and optical gel may be considered.
Types of Control
Types of Proofing Technique
- Spiking: This method of proofing is to dissuade birds and prevent them from alighting on the surface. They are very adaptable and can be used to proof a wide variety of plain or ornate buildings.
- Netting: Bird netting systems, which screen off problem areas, can give 100% success when installed correctly. Nets come in sizes to suit House Sparrows, Starlings, Feral Pigeons and Gulls. They can also exclude other birds too. Netting can be specified in several colours to suit the building’s masonry as well a no-flame version.
- Post And Wire: Post-and-wire systems are tried and tested applications, which can be used on ledges, ridges and other structures to prevent both Pigeons and Gulls gaining foothold.
- Electrical Systems: The Avi-shock system is cleared for the use in the UK under the Wildlife and Countryside Act 1981 and is a low profile track system that will deter all species of birds from landing on alighting surfaces.
- Physical Barriers: Plastic strip curtain doors should always be considered for large openings where bird ingress into buildings causes problems.
