Whites Bird Netting (1.3cm) is an economical, small aperture and light-duty netting ideal for use in bird enclosures, as a guard against vermin and it's also popular for craft use. It is made from galvanised steel wire for strength and additional protection from the weather. It comes standard in 50m packs and is also available in convenient 2m, 5m and 10m packs for smaller jobs. Note: It is recommended that new galvanised wire mesh used in aviaries and pet cages be treated to remove excess zinc that could possibly harm pets. Shave off any zinc spikes with a utility knife. The mesh should then be scrubbed with a mild solution of vinegar (2 cups in a bucket of water), and rinsed with clean water.
