Can high-tech sonic mosquito repellent App or other sonic mosquito repellent devices really repel mosquitoes?

Of course not. Mosquitoes are not fools.

This summer's popular mosquito repellent mobile phone software and "sound wave mosquito repellent" adopt the principle of sound wave mosquito repellent, and the mosquito repellent effect is good. On July 2nd, under the guidance of Beijing Science and Technology Association and Capital Internet Association, Beijing Science and Technology Journalists Editors Association and Beijing regional website jointly published the "Monthly Scientific Gossip List", which refuted the sound wave mosquito repellent.

truth

The vibration frequency of mosquito wings is about 250 to 1000 times per second. The specific frequency is related to the species of mosquitoes, and the values of different mosquitoes are different. So even if a certain frequency band of sound waves can really drive away some mosquitoes, it can't be effective for all mosquitoes.

Foreign scholars have tested three kinds of ultrasonic mosquito repellent devices in different frequency bands, and the results show that these devices can not effectively repel mosquitoes. The US Federal Trade Commission and the State Environmental Protection Agency conducted a rigorous review of ultrasonic mosquito repellent products, and the results showed that there was no evidence that these devices were effective.

As for the so-called mobile phone mosquito repellent APP software that can emit ultrasonic waves, it is a big joke. These APP softwares can't release ultrasonic waves at all. The mosquito repellent APP software has been buzzing and releasing ultrasonic waves is not the same thing. Most people can't hear ultrasound at all. Let's take 10,000 steps back. Assuming that ultrasonic electronic mosquito repellent is really effective, people have to receive ultrasonic waves for a long time to prevent mosquitoes, which is very harmful to human health. As for the "buzzing" sound from mobile phones, otolaryngologists say that people's ears are prone to irritability and physical discomfort when they are in this monotonous sound for a long time.

So don't believe rumors.
