Birds have the ability to get into gaps that are as small as 3/4 of an inch (depending on the bird species), so specialized netting material is needed to provide adequate protection from bird entry. Nets come at various gap sizes, lengths and heights. They range from 10ft x 10ft, 25ft x 25ft, 50ft x 100ft and possibly some custom sizes; however, usually, the netting may have to attached together if it is not the adequate size. Bird netting can be used alongside buildings and to enclose areas off completely. They can be ordered in different colors. Manufacturer provides a 5-year warranty on the product.
