This is an ultrasonic electronic pest repeller.
It is designed to deter pests like spiders, mice, mosquitoes, rats, and ants using high-frequency sound waves that are inaudible to humans.
The device is odorless, noiseless, and operates without chemicals, making it a safe and economical pest control option.
It is a plug-in device suitable for use in various indoor locations such as kitchens, bedrooms, and warehouses.
The effective range is approximately 800-1,200 square feet, but the ultrasonic waves cannot penetrate walls, so one unit per room is recommended.
Disclaimer: Scientific evidence supporting the long-term effectiveness of ultrasonic pest repellers is inconsistent, as pests may adapt to the sound waves over time.
