I have bought so many mosquito repellent patches , mosquito repellent bracelets, mosquito repellent lamps and other mosquito repellent products. Why can’t mosquitoes bite me?

Once upon a time, B vitamins became a folk remedy for repelling mosquitoes and was widely circulated on the Internet.
BUT! In fact, neither spraying an aqueous solution of , vitamin B1, , nor taking vitamin B1 directly has any mosquito repellent effect.
Mosquitoes don’t care whether you are deficient in B vitamins or not, they just want to communicate with you.
The human cubs downstairs all have a mosquito repellent bracelet . Some wealthy households even wear one on each arm and leg, but their fleshy calves still have traces of mosquito bites.
Most mosquito repellent bracelets and mosquito repellent patches claim to "use naturally extracted essential oils to release odors to repel mosquitoes." They do not smell like mosquito coils, and they do not need to be connected to a power source to repel mosquitoes 24 hours a day.
But if you think about it carefully, isn’t it just that there is plant repellent in the bracelet?
What is the difference between spraying toilet water on clothes? ? ?
Moreover, mosquito repellent bracelets and mosquito repellent patches cannot provide full-body protection, and they evaporate quickly. It can be said that they are more gimmick than practical.
UV mosquito repellent technology seems to stand on the shoulders of science and solve practical problems.
However, research has confirmed that only a very small number of mosquitoes killed by ultraviolet mosquito killer lamps are true blood-sucking mosquitoes. Most of the mosquitoes it collects are male mosquitoes that do not suck blood and distant relatives of mosquitoes " chironomid ".
The main blood-sucking mosquitoes in China are Culex pipiens, Anopheles sinensis and Aedes albopictus ; while chironomids often appear in water sources such as lakes in parks, and the group of cranes dancing in the air looks quite intimidating. But it doesn't actually bite people.
Moreover, not all mosquitoes like light sources. For example, Aedes elegans and Anopheles sinensis like to go out at night when it is dark and windy, and some mosquitoes do not respond to ultraviolet light at all!
The principle of ultrasonic mosquito repellent is mainly to simulate the sound of male mosquitoes to drive away blood-sucking female mosquitoes.
The most serious bites in summer are female mosquitoes during pregnancy. At this time, female mosquitoes will avoid male mosquitoes. Taking advantage of this characteristic, the manufacturer designed an electronic frequency conversion circuit to make mosquito repellent produce ultrasonic waves similar to the flapping wings of male mosquitoes. , to achieve the purpose of driving away female mosquitoes.
This product makes a rhythmic "didi" sound when used, and is advertised as harmless to the human body.
However, different types of mosquitoes perceive ultrasonic in different frequency bands. Even if a single mosquito repellent is effective, it can only affect a single type of mosquito, and the effect is minimal.
Moreover, doctors from the otolaryngology department said that if the human ear is exposed to monotonous sounds such as "didi" for a long time, it is easy to produce irritability and physical discomfort, especially infants and young children with weak tolerance, which may cause crying.
It can be said that it hurts the enemy 800 and damages itself 1100...
Geranium , Basil , Rosemary , pepperwood, lavender ...
These pure natural green plants are popular among literary youth + life experts This is a highly popular mosquito repellent product.
The seller said that these green plants themselves emit a smell that mosquitoes don’t like, and this smell has no effect on the human body. Therefore, buying such green plants and placing them at home to repel mosquitoes is not only effective, but also safe.
But in fact, the mosquito repellent ingredients in plants do not volatilize into the air casually. Even if some of the mosquito repellent ingredients volatilize into the air, the effect is minimal.
Some mosquito repellent apps are absolutely amazing! There are not only ultrasonic waves to repel mosquitoes, but also ultrasonic waves in different bands to repel sparrows, bats, etc.!
said that as long as it is turned on, it can make various sounds that are annoying to mosquitoes, thereby achieving the effect of repelling mosquitoes.
However, some netizens complained: "The only use is to waste electricity!"
And...the mobile phone speakers are designed based on the human ear, and the ultrasonic waves they can emit are very weak. I wonder if mosquitoes can really hear them?
Netizens spontaneously contributed their own unique secret weapon - homemade internet celebrity mosquito repellent water !
Just add beer, sugar and a certain amount of glue to a disposable cup to make mosquitoes fall into the trap.
The principle is: beer and sugar can attract mosquitoes, while glue can stick to mosquitoes. This statement may be derived from the fact that "people who like sweets and drink beer are more attracted to mosquitoes."
After a person eats sweets, the sugar decomposes and releases a large amount of heat, causing the body surface temperature to rise and sweating easily;
Alcohol will increase the drinker's body temperature and make them sweat more.
But mosquitoes are attracted by the higher body temperature of humans, as well as the lactic acid, amino acids and ammonia compounds in sweat, not beer and sugar themselves.
To sum up, most of these fancy "Internet celebrity" mosquito repellent methods are useless. The truly effective mosquito repellent methods are the most traditional mosquito coils, mosquito repellent liquid , and electric mosquito swatters , mosquito nets, screens and other physical methods. method.
In addition, if you want to fundamentally prevent mosquitoes, you must start from the living environment. You must promptly clean the water in sewers, rainwater grates, bottoms of flower pots and bottles and jars, and completely eliminate mosquito breeding places.
