The Yard Sentinel Outdoor Ultrasonic Animal Repeller With Motion Sensor is a safe and effective way to deter animals and pests from yards, home spaces, gardens, and more, using sonar technology instead of harsh chemicals. The standing deterrent has three sonar levels that can be controlled to deter different sized animals, and also scans the yard all day, every day to deter animals who come through. The waterproof sensor can stay outdoors in the yard through all four seasons of the year and help to protect sensitive plants and private yards so they stay pristine year-round.

Customers say they like this animal repellent because it has proven to work well for small to medium sized animals. From cats and raccoons to chipmunks and birds, this deterrent has safely coaxed these animals from invading the yard around a home, many say. They say the machine is nonchalant in a backyard space because it is green, and overall works for a long time without needing to replace batteries.

Some say larger animals like cats are not deterred by this device.
