Ultrasonic Rodent and Insect Repellent, 4 Pack Ultrasonic Mosquito Repellent, Indoor Electronic Insect Killer for Mice, Rats, Ants, Spiders, and Mosquitoes -

【Safe and Eco-Friendly for Everyone】: This ultrasonic mouse repellent uses a physical principle, leaving no odor or chemical residue, making it environmentally friendly. The ultrasonic waves emitted by the mouse repellent are inaudible to humans and harmless to animals like cats and dogs, allowing for worry-free use anywhere. 【Dual Ultrasonic and Electromagnetic Technology】: This ultrasonic mouse repellent integrates ultrasonic and electromagnetic waves. The ultrasonic waves stimulate the hearing and nervous system of mice, and the waves propagate through electrical wires, penetrating walls to eliminate hidden rodents and enhancing repellent effectiveness. 【Automatic Variable Frequency to Prevent Adaptation】: This ultrasonic rodent repellent with a microprocessor automatically varies the ultrasonic frequency (13kHz-55kHz), preventing mice from adapting to a fixed frequency. This ensures a long-lasting and effective effect. 【4-Device Pack for Complete Protection】: This powerful ultrasonic mouse and rat repellent is a set of four devices designed for large areas such as homes, warehouses, and restaurants. Use the powerful ultrasonic mouse and rat repellent in multiple locations (kitchen, corners, entrances) to create a network with no blind spots, overcoming the coverage limitations of a single device and ensuring comprehensive rodent protection. 【Easy Installation and Low Power Consumption】: This mouse repellent is a plug-and-play device; simply plug it into an outlet to get started. Install it 20-80 cm from the floor and avoid absorbent materials such as curtains or carpets for optimal results. Low energy consumption, supports prolonged continuous operation.
