Ledges and Parapets

Ledges, cornicing and parapets are one of the most common problem areas associated with pest bird infestations. By their very nature they offer birds a high-up perch, roost and even nest site, often overlooking a food source. Sheltered ledges with overhead cover or in the lee of the building, away from prevailing wind and rain.

Which species can cause problems?

Predominantly Feral Pigeons and on Larger ledges and parapets seagulls (Herring Gulls and Black-Backed Gulls)

What are the problems?

Unsightly fouling & staining of the building’s façade with bird droppings & guano Dangerous build-ups of bird droppings on the floor below the ledge, presenting a slip hazard and disease transfer risk. Damage to building fabric. Faecal matter absorbs into stonework, tarnishes metallic and painted surfaces and causes damp through retention of moisture. Bad smells from high build-ups of faecal matter, dead birds and nests. Infestations of ticks, lice, mites and other biting insects into the building associated to the kedge infestation. Noise problems inside the building from the gathering of birds outside. Parapet walls often have drains behind them which will eventually block from nest debris and faecal matter. Often the water has nowhere else to go and will eventually cause flooding through the building.

How can I stop the problem?

An extensive range of solutions exists to protect ledges depending upon the severity of the bird infestation pressure present.

Light Pressure, perching only no food source present
Ultrasonics
Bio-Acoustics
Bird-Repellent Gels & Liquids
Visual Deterrents

Medium Pressure, roosting overnight either with or without a food source present and perching but with food sources present.
Anti-Perch Spikes

Heavy Pressure, Nesting, with or without food sources.
Netting

To improve your success rate try to remove any food sources prior to installing your chosen deterrent.
