Ultrasonic rat rodent repellent systems are devices that emit high-frequency sound waves (ultrasonic waves) to deter rats, mice, and other rodents from entering or staying in a specific area. These devices are often marketed as humane, non-toxic alternatives to traditional traps, poisons, or chemicals. The sound waves emitted by these devices are typically at a frequency higher than what humans can hear (usually between 20 kHz and 65 kHz), but they can be heard by rodents.
