What Do Crows Hate?

Use balloons, CDs, reflective tape, or anything else shiny to scare crows away. For some reason, shiny, reflective objects scare crows. Some people think that it's because crows are scared of their own reflection.

What will keep crows away?

Crows avoid effigies of dead crows (never the real thing). Halloween décor crows, hung upside down with the wings spread, usually work. Highly reflective Mylar® tape or bird tape, hung in streamers or twisted and strung to make a temporary fence can frighten crows away.
