Holographic Tape is a silent, inexpensive product for repelling 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 4 on a fruit tree. Cut the lengths up to one metre long.
