1、According to long-term research by zoologists, female mosquitoes need to replenish nutrients within a week after mating in order to successfully produce ovulation, which means that they will bite people and suck blood only after they are pregnant.During this period, female mosquitoes can no longer mate with male mosquitoes, otherwise it will affect the production, or even life.The female will try to avoid the male.Some ultrasonic mosquito-repellents mimic the sound of fluttering wings of various male mosquitoes.The blood-sucking female mosquito hears the sound waves and immediately runs away, thus achieving the effect of repellent mosquitoes.According to this principle, an electronic frequency conversion circuit is designed for the ultrasonic mosquito repellent, which can produce ultrasonic waves similar to male mosquitoes flapping their wings and drive off female mosquitoes.
2、Dragonflies are the natural enemies of mosquitoes. Some products imitate the sound made by dragonflies flapping their wings, so as to drive away all kinds of mosquitoes.
3、The mosquito-repellent software simulates the ultrasonic sound emitted by bats, because bats are the natural enemies of mosquitoes. It is generally believed that mosquitoes can recognize and avoid the ultrasonic sound emitted by bats.
