An ultra sonic dog repellent is a device that works similarly to a wireless dog fence, except that it’s meant to keep dogs away from your yard instead of contained to an area. This device deters dogs from coming near you or your lawn by detecting animal movement and releasing an ultra sonic high-frequency noise that only dogs don’t like. Humans can’t hear the noise, but most dogs and smaller animals can. An ultra sonic dog repellent usually includes a stake to place it into the ground to protect your yard. It uses motion detection technology that signals when an animal is close, triggering the device to make its noise. Some of these devices also have flashing LED lights designed to scare away animals that might not be bothered by the sound.
