The Poly Stock Whip is an auditory deterrent. Whips have been continuously in use since humans first started domesticating animals. When cracked, the end of the whip breaks the sound barrier, creating a sonic boom that echoes across a surprisingly large area. The visual effect of the swinging whip adds a second element of fear, keeping birds on edge and afraid.

The Poly Stock Whip is made from high-quality polyethylene, making them more durable than nylon and require no breaking in period. Unlike nylon, polyethylene does not deteriorate when exposed to UV rays.
