Does the super insect repellent spread information or energy by sound?
Ultrasound has been used to drive away mice and insects for a long time. Experiments show that ultrasonic can attack the hearing and nervous system of most pests, causing them extreme pain and discomfort, thus forcing them to move out of the sound range of this machine to achieve the effect of insect repellent. The previous ultrasonic insect repellent used a fixed frequency, which was easy for mice and insects to adapt, and failed. This kind of insect repellent adopts advanced computer frequency conversion technology, which makes the emitted ultrasonic frequency continuously scan and change within a certain range, thus preventing the adaptability of mice and insects caused by fixed frequency.

2) mosquito repellent principle:

According to the data of long-term research on the living habits of mosquitoes by zoologists, only female mosquitoes will suck human blood and animal blood, because female mosquitoes need to be supplemented with nutrition to ovulate and give birth smoothly within one week after mating, and during this period, female mosquitoes can no longer mate with male mosquitoes, otherwise it will affect production and even worry about their lives. To put it simply, female mosquitoes will bite and suck blood after pregnancy, and what they are most afraid of at this time is the pursuit and mating of male mosquitoes.

At the same time, it includes the frequency of various male mosquitoes flying after female mosquitoes. When female mosquitoes hear the male mosquito frequency emitted by this mosquito repellent during pregnancy, they will escape from the sound range of this machine. /academy-note-559.html So I think you are right.
