Stealthnet special knotted netting just for bats. Our 3/8 polyethylene knotted mesh is ideal for all bat species and is far stronger than other nets available. The black mono-filament withstands ultraviolet radiation extremely well, and is very hard to see when installed in shadowed areas. Another great feature is the large sizes available so any bat exclusion is possible with a single sheet, eliminating any cause for seams.
