Bird Netting is a highly effective and durable method of preventing birds from accessing many areas and structures and in many cases can appear virtually invisible to the passer-by. The polyethylene netting we typically use for most applications is made from 12/6 twine, formed in a knotted square mesh. It is UV stabilized and chemically inert and rot proof. Depending on the birds that are causing the bird control problem we may suggest a 19mm gauge for smaller species, ranging to 50mm gauge and 75mm gauge for larger species such as pigeons or gulls. At Bird Environmental Services Ltd, we many over 20 years experience of the best way to use, install and tension Bird Netting to best effect.
