It consumes less power, is silent, and 100% safe for people and pets. Quiet and Effective: The ultrasonic repellents operate using low-frequency ultrasound. The emitted ultrasonic waves are designed solely for pest rats and will not harm humans or animals. Typical results may take 3 to 4 weeks depending on the severity of the pest infestation. Next-generation ultrasonic technology: The ultrasonic insect repellent stimulates the auditory nerve with ultrasound in the frequency range of 20 kHz to 65 kHz and disrupts the central olfactory system.
