It's an excellent choice as an indoor spider repellent, crafting an environment where you and your family can live comfortably and thrive. Installing our ultrasonic rodent repellent is a breeze. Just plug it into any standard outlet, and watch as it starts its magic. Operating within a frequency range of 10kHz to 65kHz, it emits ultrasonic waves. These waves are completely harmless to humans and beloved pets but act as a powerful deterrent to pests. The waves create an uncomfortable environment for pests, compelling them to leave your home in search of more hospitable places. Our indoor ultrasonic pest repellent has an impressive coverage area of up to 1600 square feet, making it perfect for various spaces within your home. Whether it's the cozy bedroom where you rest, the busy kitchen where meals are prepared, or the often - neglected garage, it can effectively drive away pests. For optimal results, position it vertically, at a height of 10 to 50 inches above the floor. This height is ideal for targeting those hard - to - reach pests that like to hide along the walls. In cases of severe pest infestations, don't hesitate to deploy multiple units. Using several of these repellents simultaneously can significantly amplify the effect, ensuring that no pest can withstand their combined power.
