Flying sulfuric acid
With the end of the May Day holiday, the weather has begun to get hotter and hotter, and many people have begun to look forward to summer air conditioning and watermelon.
However, while we are looking forward to the cooler moments of summer, we should also be wary of "mosquito" bites, because the slightest mistake can lead to the risk of "disfigurement".
Recently, the news that a Hunan woman was "attacked" by cryptoptera and caused her eyelids to rot caused panic, after all, in summer, how to fight with mosquitoes is a big headache.
However, if you encounter ordinary mosquitoes, it is fine, but if you encounter "cryptoptera", it will be more unlucky.
As the news of this woman appeared on the Internet, many netizens came forward to share their experience of being "harmed" by cryptopteryx.
Some netizens said that when they were young, because they didn't understand the characteristics of cryptoptera, they mistakenly rubbed it off as an ordinary insect, and as a result, it was swollen on the third day.
This large patch is different from the small itchy packets that we are bitten by ordinary mosquitoes, it has a large area of swelling and needs to be treated with the appropriate medication.
In addition, some netizens said that they had been bitten by cryptoptera, and although they were disinfected in time when they were found, their necks were still "hot" and painful the next day, and even if they were smeared with drugs to suppress it, it still didn't have much effect.
Including last year, some netizens said that they successfully "killed" a cryptoptera, but accidentally rubbed the venom on their arms when dealing with it, which caused dermatitis and did not heal for a week.
It seems that there are not a few people who are deeply troubled by cryptoptera every year, and these are the "painful" experiences of being attacked by cryptopteryx.
Of course, there are also netizens who are lucky enough to be "good", and there are special situations.
A netizen did not feel unwell after being bitten by a cryptoptera, but he was left with a few circles on his arm, which did not slowly disappear from his arm until a year later.
It can be seen that this cryptoptera is very virulent.
It can not only cause ulcers on human skin, but even leave scars, which is simply a nightmare for people with "scar constitution".
So, what is this species of cryptoptera that causes skin ulceration and torture?

Beiqingwang: This insect is called "flying sulfuric acid", which has entered an active period, and many people have been attacked!
Cryptoptera
This so-called cryptopteryx, also known as the shadow worm and the green-rumped worm, is a small insect with a strong acidic venom.
As we all know, sulfuric acid is also very acid-corrosive, so this cryptoptera also has a unique and terrifying name, that is, "flying sulfuric acid".
For cryptoptera, the name is not unjust at all.
If people get the venom in its body, it will definitely cause dermatitis, and even in severe cases, like the girl just now, the skin will rot.
Cryptoptera has a unique body structure, each segment of its body contains toxins, and there is an anus at the end of the abdomen, which secretes venom.
Not only that, but the acid nature of the envenom of Cryptoptera is very large.
Hydrochloric acid, as we know, is already very corrosive and reaches the lowest pH value of 1, while the body fluids of the cryptoptera are as "high" as it is, and they are all at the lowest value of 1.
It can be seen that the venom in the body of the cryptoptera is very powerful, but why does the cryptoptera with such a strong toxicity appear around us, or even at home?
There is a saying that I believe everyone has heard: "a spring rain and a heat".
Summer is the most common season of the rainy season, and Cryptoptera happens to like to come out after the rains in summer and autumn, which is their favorite season.
Cryptoptera is usually found in moist grasslands, and it prefers to live in humid areas, so in the south, this insect will be a little more numerous.
However, it is not that the north is completely gone.
The distribution of the cryptoptera is very wide, almost all over the world, its slender body, small size, and short and thick elytra, and well-developed hind wings, these characteristics are its hiding advantages.
Not only that, but during the day, the cryptoptera prefer to hide in dark and damp places, and at night, it is the time for them to come out for "entertainment".
Grasslands, vegetable gardens, ponds, and farmland are common places where cryptoptera likes to play.
However, they will sometimes cats in damp places in human habitats, and will come out from time to time to "attack" humans.
So, what is the correct way for us to deal with cryptoptera?

How to "fight" Cryptoptera
When you encounter cryptopterus, you must not think that you will be done by shooting it to death as soon as possible, because cryptoptera has the particularity of being strong and toxic, and you need to be cautious.
First of all, because of the small size of the cryptopteryx, many people may not be able to distinguish it at the first time, and they will mistakenly think that it is just an ordinary mosquito.
Therefore, you need to recognize and remember the appearance characteristics of Cryptoptera, so that you can distinguish them at the first time.
Of course, in addition to cryptoptera, when you find other mosquitoes landing on your body, you should also try not to choose the method of "slapping to death".
Sometimes when the mosquito sucks blood, if you shoot it to death, it may cause its abdominal needles to remain in the body, thus causing various harms to the human body.
According to Zou Yang, chief physician of the Beijing Institute of Tropical Medicine, "after discovering cryptopterus, it should be gently blown off or shaken off."
If its venom comes into contact with the skin, it will cause dermatitis within 2-4 hours, which is also called cryptoptera dermatitis in the medical field.
When the human body is eroded by the venom of Cryptoptera, the skin will go through a
The process of "burning sensation - redness of the skin, gradually turning purplish-red - appearance of grayish-white pustules of varying sizes, expansion into patches or strips of pustules, blistering, crusting, brown marks on the damaged part of the skin after healing".
Therefore, when you accidentally come into contact with venom, you should immediately wash the area that comes into contact with the skin with soap repeatedly, and then wipe the damaged skin repeatedly with 4% baking soda solution or 10% ammonia.
If you do not distinguish the insect and are injured by mistake and do not know it, you should immediately go to the hospital for relevant treatment after the body has a "poisoning" reaction to prevent the skin from being damaged and expanding, which will cause more serious consequences.
In addition to this, as I mentioned earlier, the activity time of the cryptoptera is at night.
Therefore, we must check whether the screen window is closed tightly before going to sleep, and it is best to check whether there are any "fish that have slipped through the net" in the bed, otherwise it is likely to affect our sleep quality.
In particular, the cryptoptera will also make a "buzzing" sound when flying, and when people are woken up in sleep, they will subconsciously want to "destroy" it, so this will also bring us some hidden dangers.
Speaking of which, everyone thinks that our fierce enemy against mosquitoes in summer is Cryptoptera, but in fact, people need to "fight" more than one kind of insect in summer.

It is about to enter the active period
Summer is the season when mosquitoes are most common, and it is also the most active time for cryptopteryx, which according to doctors, has a distinct seasonality.
In general, the frequency of many people infected with this dermatitis begins to increase gradually from June, and the peak of the incidence is in August and September.
This is the hottest time of summer, and many people who suffer from dermatitis usually have to suffer from the double suffering of summer heat and inflammation.
From October, the prevalence began to decrease, and it was not until late autumn that the season of invisible insects basically passed.
The survival period of invisible insects is generally about 6 months, so it survives about the same time as most mosquitoes.
If you find more cryptoptera at home, you can spray some insecticides appropriately, which can also play some obvious roles.
However, it is not only cryptoptera that everyone needs to pay attention to in summer, we should be cautious about all kinds of mosquitoes.
At present, dengue fever has occurred in many countries around the world, and more than 4 million cases have been confirmed in our country.
Dengue fever is commonly known as summer flu, and it is mainly an acute insect-borne infection transmitted by the bite of Aedes mosquitoes.

Xiaokang Magazine: The mainland has entered the dengue fever epidemic season, pay attention to precautions! Keep away from this mosquito →
This epidemic is usually more serious in tropical and subtropical areas, and our coastal or border areas such as Guangdong, Guangxi, Hainan and Fujian are the most popular.
This disease spreads very quickly and has a high incidence, and the human body will have rashes and three pain symptoms in addition to fever reactions.
However, there are basically no fatal cases of this disease after timely intervention, so you don't need to be too nervous, just do a good job of mosquito prevention.
The words mosquito repellent and mosquito control are now generally familiar to everyone, and with the research and development of various new technologies, products such as mosquito repellent patches and mosquito repellent bracelets have emerged in an endless stream.
When you live in summer, in addition to closing the screen window tightly, you can also buy a mosquito net to use, which is also quite effective.
Secondly, mosquito repellent products such as toilet water, mosquito repellent liquid, mosquito coils, etc., should be used in the correct way.
Especially mosquito coils, you must pay attention to ventilation when lighting mosquito coils, otherwise carbon monoxide poisoning is likely to occur, and the frequency of use should not be too high.
On the other hand, keeping the home dry and tidy is also the most important factor in living conditions.
Bathrooms, kitchens and flower rooms are the most popular places for mosquitoes, so it is important to keep these areas dry and ventilated frequently, as well as not conducive to bacterial growth.
epilogue
Mosquito control has always been the most distressing method for everyone.
Many people know that Cryptoptera is highly acidic, but it is actually a beneficial insect, it is a natural enemy of agricultural and forestry pests, and plays an important role in the material cycle and ecological balance of natural ecosystems.
Therefore, cryptoptera is really "loved and hated".
Sometimes mosquitoes are annoying and people have to give it a "mass extinction", but this is impossible, and everyone should not bother themselves too much because of this.
After being bitten by mosquitoes such as cryptoptera and other mosquitoes, they should immediately go to the hospital for corresponding treatment, and they should also be effective mosquito repellent at ordinary times.
Don't be overly vigilant against mosquito bites in your life, but at the same time, you can't relax your carelessness, now, summer has just come, this year's "battle" has just begun, I hope you can have a good summer.
