English sparrows took up residence in the steel framed entrance way and walkway of the building. The nesting materials and bird droppings littered these public areas. We removed all bird nesting cleaned all the affected surfaces and installed a Bird Barrier 3/4″ heavy duty black stealth net to exclude the sparrows from gaining entry to the walkway and entranceway. The net is barely visible and has continued to perform flawlessly since its installation. The custodial staff is thrilled that they don’t have to clean the walkway on a daily basis.
