According to the principle, only female cyetic mosquitoes will bite, female mosquitoes will try to avoid male mosquitoes. In addition, mosquitoes have two major natural enemies: dragonflies and bats.
Based on these principles, we have designed and manufactured a new wrist-type electronic mosquito repellent device that alternately emits the sound of the beating wings of male mosquitoes and dragonflies, as well as similar ultrasonic waves. Used to repel biting female mosquitoes.
