Can mobile phones really repel mosquitoes, can light waves really repel mosquitoes?

Hello landlord, ultrasound studies of simulated male mosquitoes have found that the female mosquitoes that bite people. This is because female mosquitoes need to be supplemented with nutrients within a week after mating in order to ovulate and give birth. However, during this period, the female mosquito can no longer mate with the male mosquito, otherwise it will affect the production and even worry about life, so the female mosquito tries her best to avoid the male mosquito.

Some ultrasonic mosquito repellent devices simulate the ultrasound waves of various male mosquitoes shaking their wings. When the female mosquito hears the above sound waves, she will immediately flee to repel the mosquitoes.

Does mobile mosquito repellent software really work?Does mosquito repellent software have any effect?Experts said that it is feasible to repel mosquitoes through ultrasound from a medical point of view, and the ultrasound simulation objects used are male mosquitoes that female mosquitoes hate during pregnancyThe second is bats, which are the natural predators that mosquitoes are afraid of.

However, it should be clarified that, according to its understanding, it is actually impossible to generate ultrasound waves that make mosquitoes uncomfortable through computers or mobile phones.

Because the frequency of sound that can be heard by the human ear does not exceed 20kHz, and the sounds emitted by bats and male mosquitoes are ultrasound, among which the ultrasound emitted by bats is as high as 300kHz. That is to say, in order to play a mosquito repellent role, it is necessary to have special sound playback equipment to produce ultrasound. From a technical point of view, neither computer speakers nor mobile phones support it at all.

In addition, the sound waves of different mosquitoes are also different, and one software can only imitate one sound wave, and it is useless for mosquitoes with different sound waves, "such as mosquito repellent software made in the United States, but it has no effect on mosquitoes in China." Some experts pointed out that ultrasound is harmful to the human body after listening for a long time, which will lead to the rupture of human cells.

Yes, but it is harmful to people's bodies, so it is recommended not to use it.

Light waves must have a certain effect on mosquito repellents. Many people know that mosquitoes hide during the day and come out to bite people at night. It shows that there is an element of sunlight that mosquitoes are afraid of.

The spectrum of the mosquito repellent lamp is close to that of sunlight, so it has a certain mosquito repellent effect. Mosquitoes, bugs, and moths are all particularly sensitive to and fond of certain light, and especially averse to some light. By using special light source materials, a large amount of light that mosquitoes do not like is generated, so as to achieve the effect of repelling mosquitoes.

It will also not cause pollution to the human body and the environment. Mosquito repellent lamp and mosquito repellent lamp are not the same concept, mosquito repellent lamp is produced by professional phosphor coated in a special lampshade, generally gloss is warm yellow, filters ultraviolet and infrared rays, and will not cause any harm to the human body. The mosquito killer lamp is an electric shock to death when the mosquito is approaching, using ultraviolet rays and high pressure that mosquitoes love.

The light wave that mosquitoes are afraid of is 530-590nm, and this light wave is the most beneficial to the human eye, and it is the least likely to produce visual fatigue, so during the day, people work or labor, but mosquitoes hide in the shadow.

Effective. Tested by the Chinese Center for Disease Control and Prevention, the highest authority in Beijing, the light wave mosquito repellent rate is more than 98%. The reason why LED solar spectral lamp can repel mosquitoes is closely related to the spectral characteristics of the lamp.

Mosquitoes have different reactions to different light waves: the light waves in the 530-590nm band, which are the most acceptable to human eyes, the least visual fatigue, and the most clear, mosquitoes have their inherent biological characteristics of backlight, and they are afraid of this kind of light, and they will flee in the opposite direction when they see it; The light below 500nm is the "visible light" of mosquitoes, which has its inherent phototaxis biological characteristics, and it can see clearly under this light wave, and likes to live under this light wave. LED solar spectrum light in the sunlight mosquito fear of the light wave made a part of the solar spectrum light, so, under the LED solar spectrum light, the mosquito is very uncomfortable, it does not fly towards the LED solar spectrum light, the light opens the window mosquito does not fly indoors, but runs away when it encounters this light, the indoor does not escape to hide, and the time to hide is slowly flying in the air, and the mosquitoes that fly slowly do not bite people, which is not surprising.

If you understand the truth of light wave mosquito repellent, you don't have to worry about whether the LED solar spectrum light is harmful to people since it can repel mosquitoes. Because, the light wave that mosquitoes are afraid of is 530-590nm, which is precisely the light wave that is the most beneficial to the human eye, the least visual fatigue, and the most clear to see, so people work or work during the day, but mosquitoes hide in the shadows, and people are not mosquitoes.

Mosquitoes are the main culprits in the transmission of infectious diseases such as malaria and light fever. In order to reduce diseases and rest well, people now commonly use all kinds of mosquito coils, electric mosquito coils and various aerosol mosquito killers, all of which are chemical.

While killing and repelling mosquitoes, they are also harming humans and polluting the environment. Some people sleep and light mosquito coils overnight, and the next morning they will have symptoms such as dry throat and dizziness. The LED solar spectral lamp uses the light waves in the sunlight that are beneficial to the human eye and afraid of mosquitoes to physically repel mosquitoes, achieving the environmental protection goal of both mosquito repellent and harmless to people.

The protective film will disappear, a scholar from the Department of Entomology at Chung Hsing University believes. And there is a mosquito repellent (deet) ingredient, the concentration of 15 can last for 3 hours, two hands to touch, slap on the baby's hands and feet, and finally the hands are gone, but there is also the smell of sesame oil, will produce an oil film, mosquitoes do not like the oil film, I am afraid that the feet will be sticky and do not want to stop, camphor oil emphasizes natural, taste, and it is not convenient to use. Scholars suggest that there may be risks as well, and chemical mosquito repellent is a low dose, just pat the baby's face, climb a mountain down, and the smell is too strong, if you can tolerate it, forget it. Oil mosquito repellent has a protective effect for a short time, but after a long time, there is no greasy feeling, and the eyes of others still have to be worried.

Xu Erlie said that wear long sleeves and long pants to prevent mosquitoes.

Xu Erlie, an honorary professor at the Department of Entomology at National Taiwan University, said that any oily things, including sesame oil, only dare to fly around for a long time, as long as they are licensed by the Department of Health, they do not have to worry about using them on the human body.

Both Du Wujun and Xu Erlie emphasized that it takes about 10 minutes to half an hour to lose the anti-mosquito effect, so if you spend a long time in the wild, don't stop.

Xu Erlie and Du Wujun both believe that the anti-mosquito effect of sesame oil is not very practical, and sesame oil can prevent mosquitoes in trousers and shoes and socks? National Taiwan University, I'm afraid it won't work for a long time! The netizen took his son to the park for a test, but he used mosquito repellent when it was insufficient. It is best to keep walking around in the wild, and found that there are 3 mosquitoes who have always wanted son, peanut oil, which may be effective in a short time, but they just dare not approach, and the mosquito prevention time is from a few minutes to a few minutes, the effect varies greatly, salad oil, and the greasy feeling of sesame oil, although sesame oil, natural essential oil, mosquitoes are far away. It is not only uncomfortable to apply sesame oil to the body, lard, etc., but it must be applied every once in a while, and it is the most natural way to repeat a large amount of use, and the mosquitoes are still flying after 5 minutes of stalemate.

Circulating on the Internet, a drop of sesame oil, dripping on the hand.

Du Wujun, an associate professor of the Department of Entomology at Chung Hsing University, once tested the anti-mosquito effect of sesame oil on small black mosquitoes.

Mosquito repellent lamps can be divided into three types: electronic mosquito repellent lamps, sticky mosquito repellent lamps, and airflow mosquito repellent lamps. The mosquito repellent lamp has the characteristics of simple structure, low price, beautiful and generous, small size, and low power consumption. Because it does not need to use any chemical mosquito control substances when it is used, it is a relatively environmentally friendly way to kill mosquitoes.

The mosquito killer lamp adopts intelligent light control; Precise nano wavelength effectively traps mosquitoes, does not use any chemical agents, is safe, efficient, green and environmentally friendly; Humanized design, the computer control technology is applied to the mosquito killer, through precise calculation, set lighting, mosquito control, sterilization three major functions in one. While killing mosquitoes, it can also be used for lighting to eliminate harmful germs!

Mosquito control principle: with a special mosquito trap long-wave ultraviolet lamp, a benign ultraviolet light wave (harmless to the human body) occurs, and the bait mosquito flies fly into the mosquito suction lamp to dry and die.

The mosquito killer lamp is a simple and practical mechanical device that traps mosquitoes by releasing beam chemicals and then catches mosquitoes through a negative pressure device according to the living habits of mosquitoes. A kind of environmental protection equipment is a new generation of high-efficiency and environmentally friendly mosquito hunting and killing equipment that absorbs foreign technology and then carries out a number of technical improvements. It has basically no effect on the human body, because it is a bionics product, and it will not emit any harmful gases, so it will basically not have adverse effects.

Due to the introduction of some foreign high-tech, the mosquito killer lamp has become a new generation of efficient and environmentally friendly mosquito killing equipment due to the introduction of some foreign high-tech and then modified through a variety of technologies. Using the habit of mosquitoes phototaxis, moving with air currents, being sensitive to temperature, and like to gather, especially chasing the smell of carbon dioxide, as well as the habit of foraging for sex pheromones, an environmentally friendly and pollution-free efficient hunting tool was developed.

The traditional mosquito killer lamp is to attract mosquitoes by way of waves, according to the phototaxis of the mosquito to attract the mosquito killer lamp, and then use electric shock to kill mosquitoes, but with more and more reports pointing out that the mosquito killing method of ultraviolet mosquito killer lamp is not scientific, mosquitoes will be more easily attracted by the human breath compared to light, and the light waves emitted by ultraviolet rays will also cause damage to the skin of the body, leading to skin aging, and even inducing cancer.

Mobile phones are not used to kill mosquitoes. Methods of mosquito control include: cleaning mosquito breeding channels, using insecticides, smokeless mosquito coils, smokeless mosquito coils, and electric mosquito swatters.

1. Clean up mosquito breeding channels.

Mosquitoes appear more often mainly in the summer, and the southern ones are slightly more venomous. But whether it is in the south or in the north, there are definitely more mosquitoes in the countryside, especially after the rain, some dilapidated pots in the yard accumulate rainwater, and this kind of place has become the best place for mosquitoes to lay eggs.

2. Use pesticides.

Insecticides have always been the main way for many families to choose to repel insects, and the advantage of using insecticides to kill mosquitoes is that they are extremely resistant to stools and have strong targeting. The use of insecticides is similar to that of air fresheners, when using them, you need to close the doors and windows, spray the corresponding insecticides in the corners of the house, and try not to stay in the house after completing all the above steps, and enter again every hour and a half.

3. Smokeless mosquito Changlu incense plate.

Since the 80s, mosquito coils have been the main tool of choice for many families to control mosquitoes. The biggest feature of the mosquito coil tray is that it is relatively cheap, and before going to bed, light a plate of mosquito coils at the head of the bed or at the foot of the bed, and there will be no mosquitoes to disturb the whole night, and the effect is very good.

4. Smokeless mosquito repellent liquid.

Mosquito repellent liquid is actually similar to the mosquito coil tray mosquito repellent principle, both of which are used to drive away danger through the smell produced by heating, but the mosquito coil liquid uses electric heating to increase the volatility of mosquito coil liquid.

5. Electric mosquito swatter.

Ordinary fly swatters can not directly shoot mosquitoes, the hit rate is relatively low, electric mosquito swatters only need to press the stupid reed off, gently wave to kill, and the majority of users are worried about the safety can also be guaranteed.
