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

I was hoping for better results with this red/silver flash tape....at first the birds seemed afraid but later they returned to start nesting in my electric awning. I had to give it a try based on info. It's possible that other birds would avoid this tape but not the sparrows in Wisconsin.
