Set of 4 electronic ultrasonic repellents against mosquitoes, insects, rats, for indoor use, flies, mice, spiders, 10x5.8x4.5cm

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 destroys the central olfactory system. It can completely get rid of mosquitoes, flies, mice, spiders, etc.

【Safe for children and pets】The ultrasonic frequency is inaudible to humans and pets, and emits no chemicals or radiation. It consumes less energy and is noise-free, making it safe for people and pets.

4-pack easy to use: Simply plug the ultrasonic repellent into a standard outlet; the LED light will turn on and it will start automatically.

【Wide Coverage Area】Three functions of bionic wave + electromagnetic wave + ultrasonic wave, for highly effective 360° pest control, with coverage of up to 1,600 square feet. For best results, equip each room with one repellent.

Quiet and Effective: Ultrasonic repellents work with low-frequency ultrasound. The emitted ultrasonic waves are designed only for pest rats and will not harm humans or animals. Typical results may take 3 to 4 weeks depending on the extent of the infestation.
