Ultrasonic Scarer: The pest repeller keeps pesky insects like mosquitoes away from your home using smart ultrasonic technology that emits high-frequency sounds that we can't hear but the mosquitoes don't like. Safe for people and pets: The repeller replaces dangerous, environmentally unfriendly alternatives such as toxic mosquito repellents, strong sprays and chemicals. So you don't have to worry about children or pets accidentally coming into contact with harmful substances. Easy to use: It's super easy to get started using the deterrent - just plug it into the power outlet . When the blue LED lights up, it means the deterrent is on. For the best effect, the pest repeller should be placed in electrical sockets 25-120 cm above the floor. Quiet: People are not able to hear the frequency that the ultrasound emits, which means that the mosquito repeller is completely silent and perfect for, for example, bedrooms. Large range: The deterrent has a range of just over 100 square metres. One mosquito repellent per room is recommended as the ultrasound waves cannot pass through walls or other solid materials. Therefore, do not place furniture or the like in front of the mosquito repellent.
