Holographic Tape is a silent, inexpensive product to repel birds. Each role is 30 metres long and 50 mm wide. When exposed to sunlight the tape reflects multi-coloured light in a random chaotic manner.
The idea is to cut lengths of holographic tape and attach them to the bush or tree you want to protect from birds in a manner that allows them to blow around in the wind. For example attach 1 to 2 lengths of holographic tape to a rose bush, and 2 to four on a fruit tree, cut the lengths up to a metre long.
