Seagull control is probably one of the most difficult bird control projects. These are large birds that have a determination beyond that of Sir Ranolph Fiennes! Seagull control netting is widely used on low ridge and flat roofs, seagull netting is difficult to install because generally areas are large and heavy duty supports are required. 75mm gull net is usually fitted. You can also deter gulls with gull spikes, Daddi Longlegs or Bird Spider and some sprung wiring systems.
