Bird Control Case Studies

Residential property housing luxury apartments in the centre of London

Problem

Feral pigeons (Columba livia) were roosting on various downpipes, windowsills and girders supporting a fire escape to the rear elevation. This caused a nuisance with the accumulation of bird guano deposits below, which presented a slip hazard, hazards from pathogens associated with bird fouling and secondary pest activity from insects.

Solution

Our fully trained abseiling team carried out a netting installation to protect the whole rear of the property and the courtyard below by extending the net outwards. This was held into position by drilling eyebolt fittings into the brickwork, running stainless steel supporting wires which the net was then clipped on to. The net consisted of black polyethylene 50mm mesh size panels secured by stainless steel hog rings. This work was carried out using industrial rope access over several days and when completed prevented birds from physically gaining access to the area.

Major historical and retail tourist attraction in the heart of London

Problem

The building was having major stone work renovation being carried out and the previous anti- bird installation was beyond its shelf life. Feral pigeons (Columba livia) were roosting on various ledges and causing a nuisance by waiting to feed amongst the public below. This caused a health and safety slip risk with the accumulation of bird guano deposits below and unsightly fouling on the ledges which had the potential to damage the stone due to its acidic nature.

Solution

Our fully trained bird proofing team used a combination of access equipment to reach the areas of work, using portable scaffold towers and a mobile platform. All of our technicians are trained to work at height having received training in working at height, ladder training, harness training, PASMA and IPAF certification. In keeping with the ascetics of the building we used a stainless steel tensioned wire and post system to protect the ledges. These were configured horizontally across the wider external ledges and vertically on the narrower internal ledges of the building. These were installed by drilling holes, inserting a plastic anchor rivet, inserting the post into the anchor rivet before securing a plastic coated stainless steel wire across the posts with a spring loaded at one end to provide some flexibility and tension. This system prevents the birds alighting onto the ledges without harm.

Major high street shopping centre in Kent

Problem

Feral pigeons (Columba livia) were nesting amongst air conditioning units and roosting on various ledges causing a nuisance by fouling on the floors in a service way. The air conditioning units offered an ideal shelter to nest, with various high level cable trays, lights and ledges being perfect places to night roost. This presented risks to the health of staff and other contractors due to the accumulation of bird guano, feathers, nesting material and other detritus.

Solution

Our fully trained PASMA certificated bird proofing team installed a ‘box’ to the outer perimeter of the service area with a plastic strip curtain to allow access. This was achieved by raising the tubed protection barrier to a height to prevent damage to any bird netting, with the insides of the barrier having galvanised welded mesh panels fitted to this lower section. These were secured by drilling in to the brickwork and using quality fittings to secure the panels to the barrier. Tensioned stainless steel wire was run through a series of eye bolts on the upper sections to tension a 50mm black polyethylene net across the openings, clipped with hog rings to provide a neat taut finish. The plastic strip curtain was installed with a 50/50 overlap to prevent any birds entering and to allow ingress and egress for staff using the service area. This work was carried out over a number of days.

Major high street shopping centre in Hertfordshire

Problem

Feral pigeons (Columba livia) were roosting on lights and pipes and nesting on various ledges causing a nuisance by fouling on the floors in a large service basement. This presented risks to the health of staff and other contractors with slip hazards and risks of respiratory issues associated with pathogens contained within bird guano, feathers and nesting material.

Solution

Our fully trained IPAF certificated bird proofing team installed a number of nets to the ceiling canopies in the areas of highest activity and risk. Eyebolt fittings were drilled into the concrete ceiling to hold tensioned straining wires to support the nets. 50mm black polyethylene nets were then clipped on to these with hog rings, providing a neat taut finish. Clips were put in to various areas to facilitate access to smoke detector heads, sprinklers, lights and other areas requiring access for maintenance. This work had to be carried out at night due to daytime use, with traffic management put in to place to allow for night time deliveries to various shop units. Our bird netting system prevents birds from gaining access by providing a physical barrier and can be designed to protect a whole array of different situations such as roof plant, roof top and ceiling canopies and various building structures. These can come in a range of different mesh sizes for different pest bird species and colours to blend in with the structure background.

Major shopping centre in North London

Problem

Feral pigeons (Columba livia) were perching on the roof parapets above an open shopping precinct, causing bird fouling on to the glass canopy down below. This not only looked unsightly but caused a risk of the rain gully becoming blocked.

Solution

Our fully trained bird proofing team installed stainless steel anti-perching bird spikes along the leading edges above. These were secured into position by using a neutral adhesive to bond them into place after wiping the surface down. These prevented birds from alighting and looking over the leading edge, which was an ideal advantage point for them to look out for potential food being left from the public. Our spike systems are constructed of a series of angled stainless steel spikes on a plastic polycarbonate base, which can be glued or screwed down. These can come in narrow, wide or extra wide to accommodate different surface widths.
