Parapet box guttering offers a high-up place of safety from which pest birds can perch, drink and sometimes nest if sufficient shelter is present.

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?

• 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 ledge 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?

Parapet box guttering should be protected using netting or weldmesh to prevent pest birds from accessing the area and fouling or blocking the gutter.

Cleaning and Disinfecting

Use an avian disinfectant such as PX Ornikill or Guanaway to neutralise any bird droppings and nests before removing them to avoid disease transfer to humans.
