[Ultrasonic Pest Repellent] Our ultrasonic pest repellent uses modern ultrasonic technology to effectively repel mice (mouse repellent), rats (rat repellent), and other pests. The changing frequencies disrupt the animals' nervous system, causing them to leave the area without the need for toxic substances like poison or rat bait. [Four Intelligent Operating Modes] Choose from 4 specialized modes: Standard Mode (22-90 kHz), Pet Protection Mode (48-90 kHz), Detection Mode (12-30 kHz), and Power Mode (0.5 Hz - 90 kHz). These flexible settings make our ultrasonic repeller particularly effective against mice (mouse repellent), spiders (spider repellent), and even bats (bat repellent). [Extended Protection] With its wide range, this mouse repellent is ideal for homes, offices, warehouses, and outdoor rat control. The ultrasound penetrates every corner of the room, protecting against rodents and insects without leaving any chemical residue. [Plug & Play Function] Simply plug it into a wall outlet or connect it via USB-C; our mouse repellent requires no complicated installation. The automatic frequency variation prevents pests from becoming accustomed to the sounds. Ideal for long-lasting protection in the home and garden. [Scientific Principle of Action] The ultrasonic mouse repellent generates high-frequency sound waves, inaudible to humans, that repel rodents and insects. The constant frequency change (12-90 kHz) prevents animals from becoming accustomed to the behavior; more effective than conventional methods such as rat bait or mouse poison.
