Deer – Ultrasonic Repeller

Q: Is there a product that repels deer with ultrasonic sound?

A: Ultrasonic repellers are ineffective at detering deer, rats, squirrels and mosquitoes.

The University of Vermont says of stationary ultrasonic devices: “Deer quickly become used to stationary objects and sounds and so, if ultrasonic or similar sound emitters or radios are used, they should be rotated frequently. If radios are used, they should be tuned to all-night talk shows, as human voices are more effective than music, and don’t have to be very loud to be effective.”

I conclude from this statement that if you download my Saturday morning radio show podcast and play it in your garden at night, I could be your most effective sonic deer repellent.
