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 also popular for craft use. It is made from galvanised steel wire for strength and additional protection from the weather . It comes in convenient 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 the 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. image in the photo gallery at the top of this page
