Bird B Gone MMFT-050 1' X 50' Reflective Bird Deterrent Flash Tape - Scare Birds Away from Gardens, Farms, and Outdoor Areas

We don't really know if it's the Flash Tape (which we tied to a couple of patio chairs - always a little breeze flipping it about) OR the fishing line we strung across the patio columns (above the tallest person but maybe about the height that the birds fly in), but we've had no bird droppings for several weeks. On the other hand - I advised a friend about trying it for her Canadian geese (who generate 1 lb of green slimy poo daily). HAH - forget it -those geese are just too smart. She found a video in looking for reviews showing a bunch of geese eyeing these flapping tapes across a wire. After a bit they waddled right under the Flash Tape with no fear. So it's back to bottle rockets for her.
