Post and wire systems have been used for many years to keep pigeons and gulls off of buildings' ledges, parapets, signs, beams, pipes, gutters, roof ridges, etc. The systems are cost effective, extremely versatile and a totally humane bird deterrent. If installed correctly are also very discreet.

By placing thin stainless steel wires tensioned with springs just above where the birds normally nest it will deter all but the most persistent birds landing.

Post and Wire systems are the ideal solution for light pressure areas. They can also be used in edium pressure situations but if it is an area where there are numerous birds present in daytime xtreme care must be taken when installing.

Care should be taken when installing post and wire systems as damage can be caused when drilling. Holes for drive rivets should be 6.5 mm diameter x 28 mm deep and at not more than 75 mm centres across the ledge, with typically 1.5 m to the next holes along the length to be proofed. 150 mm and 115 mm posts should be used.

Where drilling is not possible [on metal flashings] stick-on posts can be used. These posts are shorter than standard as none of the length is 'lost' below the surface [use 130 mm and 90 mm posts] with stick-on bases. MS POLYMER or a rapid set adhesive should be used. Do no stick onto dirty or greasy surfaces, new lead flashing [the surface has an oil coating], painted or glazed surfaces, copper or slate [the glue will only stick to the top layer], deteriorated stone or brickwork, soft stone [the tension on the post may cause damage]. Also do not stick on heavily oxidised girders or old lead, asphalt or mineral felt, wet or icy surfaces.

A heavy duty version of the pigeon post and wire system. Gull posts are 5mm diameter x 200mm long stainless steel. 

Plugs are 6mm.

0.96mm S/S, wire is secured to posts using 1mm copper ferrules.
