if you ever had pigeons nesting on your balcony or just living in the building you will know their nest and surrounding is a shit hole. literally. + they wake up way to early in the morning,
and make funny sounds!
if you thinking what to do? the only way to get rid of them is a net.
don't wast your time on finding any other solution. no shinny eyes cat reflector, smell sprays,
sting plates, dead plastic birds etc.... will help.
installed our net with hooks at the bottom, so we can easily open it for hanging out the futons or just for the view.
