Simple and affordable bird control without the use of chemicals - Holographic Scare Tape is easy to install, but incredibly effective, thanks to the shiny holographic pattern on the tape. Tie this tape around plants or crops you'd like to protect, preferrably just before they ripen and feeding patterns become established. Light from the sun will hit the tape and cause flashes and movement that will startle birds that might come to feed. It is recommended that you elevate the tape at least three feet above crops so that it may be seen from all directions, and that you twist the tape in a spiral to maximize light reflection. Each roll contains 100 feet of tape.
