With the arrival of spring, the temperature rises, everything recovers, and spring comes with not only budding flowers and bones, mosquitoes and insects that lie dormant in autumn and winter also quietly come to us with this spring season.
Last week, I took my baby to climb the mountain every day, knowing that there are many mosquitoes on the mountain, I will help the baby spray mosquito repellent before going out every time, although it will still be bitten, but it can reduce the number of bites.
That day to the door to meet the neighbor child, she usually with my baby play better, see we are ready to climb the mountain, she must follow, two children together to climb the mountain added a lot of fun, but the neighbor child did not do a good job of protection before going out, the face was bitten by mosquitoes everywhere is a bag, and finally because of the itch can not stand it, crying back home, see her mother's distressed eyes, I feel very sorry.
Every spring and summer, especially some young babies, after being bitten by mosquitoes, can only express their discomfort by crying, so they often cry and make adults very uncomfortable.
The most painful thing in the world.
Not bitten by mosquitoes.
Instead, I was about to fall asleep and suddenly heard, Yu Yinoon
A gentle sound at this moment definitely has a deafening effect, making people wake up immediately, and countless swear words instantly roll in their minds.
So why do mosquitoes like to buzz when you're almost asleep?
1.It's dark
Mosquito. A typical creature that does not see light.
On the one hand, because it has a natural preference for damp and dark environments.
On the other hand, various lights are radiated from sunlight.
will interfere with its perception system.
When you go to bed at night, turn off the lights, and the whole room is dark, which is the time for mosquitoes to find food.
The mosquito master who had a day off began to get busy.
And it's not stupid either.
During the day or when the lights are on.
Come and attack.
It's simply that. Clearly defiant.
2.Because one is easier to get started
Humans who are asleep are obviously better at dealing with mosquitoes that can't move their arms and legs.
And I have to say that the mosquito has the ability to judge whether you are asleep or not, second only to your mother.
He didn't expect it, if he doesn't move his body, he won't let it let down his guard.
Only by feeling that your body temperature, heat, and breathing are leveling off.
Mosquitoes will rush over and attack.
Therefore, it is probably useless to pretend to be asleep and hold your breath to conduct counter-reconnaissance, because at this moment.
Your breathing rate and the amount of heat you release are not the same as when you were actually asleep.
Maybe you can fool your mother.
But you can't fool mosquitoes.
3.Because you're giving away heat
Mosquitoes have thermotropic properties located by temperature.
At night, when the lights are turned off, the whole room is basically just you still dissipating heat.
At this moment, in the eyes of mosquitoes, you who are drowsy in bed are a little red in the darkness.
And there is experimental proof.
Within 31C to 40C.
The higher the temperature, the better the mosquito appetite.
The higher the temperature in the red box, the greater the density of mosquitoes, and the human body temperature is exactly in this range.
It's simply full of mosquitoes, a deadly attraction.
Because, you're breathing, yes, it's also a mistake to touch a mosquito to breathe.
Even if you are asleep, carbon dioxide can breathe and create a continuous stream of air near your head.
A lot of people don't know.
The carbon dioxide we exhale is also a tool to attract mosquitoes.
1. The baby sweats a lot
Compared with adults, babies have a more vigorous metabolism and are more likely to sweat. Mosquitoes' antennae have a strong sense of smell, and they are unusually sensitive to the smell of sweat.
After the child sweats, the mosquito will find the baby's body through the small molecules of sweat in the air, so the baby who loves to sweat is more susceptible to mosquito bites.
2. The baby has a milky fragrance
Many babies have a milk scent, which will attract the attention of mosquitoes, and if the body lotion or talcum powder that the mother usually uses for the baby has a fragrance, it is easy for mosquitoes to find the door along the smell.
Therefore, after bathing in the summer, mothers try not to use scented skin care products for their babies.
3. The baby lacks the ability to be prepared
The smaller the baby, the less sensitive, and sometimes the mosquito bites for a long time, and the child seems to have no feelings. When the bite has passed, a child reacts to the uncomfortable feeling.
Since a child does not do anything when it is attacked by a mosquito, mosquitoes are more likely to bully the child.
Therefore, compared with the sensitivity and defensiveness of **, mosquitoes prefer small babies.
Spring and summer are hot, many parents take their children to stay in the air-conditioned room during the day, and will only take them out when the sun sets and cools, and at this time, it is also the time when there are the most mosquitoes and children are most likely to be bitten.
As we all know, summer is the most active season for mosquitoes, which is inseparable from the hot summer temperatures.
The development of mosquito eggs and larvae is directly related to temperature
Mosquito larvae usually live in ponds, swamps, ditches and other places where the water flow is still, and they often float upside down with their tails against the surface of the water, and use the snorkel near the tail end of their abdomen to breathe directly from the surface of the water.
Taking Aedes aegypti mosquitoes, which is widely distributed all over the world (including southern China), as an example, experiments have found that when the water temperature is about 26 °C, the survival rate of Aedes aegypti larvae is the highest, which can reach 905%。
But don't think that the hotter the weather, the more active mosquitoes are, in fact, mosquitoes are also afraid of heat.
Aedes aegypti mosquitoes are able to fly in temperatures ranging from 18 to 35°C, with the best temperature for their activity being 26°C, above 35, mosquitoes rarely breed.
People know that when they take shelter in an air-conditioned room, mosquitoes will also fly to the shade and wait for the sun to set and the temperature will drop before coming out.
Common domestic Culex pale and three-banded beaked Culex mosquitoes, etcThe peak of bloodsucking is in the early morning and late afternoonSome friends avoid the scorching sun during the day and only go out for a walk at night, which may happen to meet the mosquitoes who come out for business.
In order to avoid mosquitoes, resourceful parents always tend to buy high floors when buying a house, but there will still be mosquitoes at home.
Why do mosquitoes always appear in your home on the upper floors of your house by surprise?
First of all, mosquitoes weigh an average of 2The lightness of the body at 5 mg gives them advantages, such as being able to migrate well with the help of other external forces or media.
"Riding against the wind" is an important skill. Scientists have found thatMosquitoes in the air are often able to fly up to 290 meters above the ground overnight, or even cover distances of hundreds of kilometers.
Although there is no similar study in the city, it is not difficult for mosquitoes to fly over a dozen floors with the help of air currents.
In addition to wind, mosquitoes can also migrate with the help of other "vehicles" such as people and animals. Not only people will be bitten,Other mammals, as well as birds, are also often "victims" of mosquitoes.
When mosquitoes follow "food" or "lower their mouths" on the same target multiple times in an attempt to find a blood vessel, it is not difficult to be carried farther away as they move (imagine that mosquitoes may also be carried by birds).
In addition, studies have shown thatThe most critical factors that attract mosquitoes are carbon dioxide, heat, and moisture; Of course, there are specific onesBody odor (such as sweat and foot odor) and several body surface chemicalsCan increase someone's chance of being bitten by mosquitoes.
This also seems to give us another way for mosquitoes to "go upstairs":Take the elevator.
Due to the high frequency of use and poor ventilation of elevators in residential buildings, the heat, carbon dioxide, and specific odors carried and residual in use will inevitably attract mosquitoes, and mosquitoes are likely to be taken to higher floors when they enter the elevator.
In this way, it is not surprising that there are mosquitoes on the upper floors as well.
After the child is bitten, the local ** will become red and swollen, making the child feel itchy. After the child is bitten, the child expresses some of the expressions and does not understand, only knows that it is itchy and uncomfortable, so I scratch it.
Many children can't help but scratch with their hands, which leads to bacterial infections. After a child is bitten by a mosquito,How will it affect your child?
1. Infectious diseases: After a child is bitten by a mosquito, the impact on health is still quite large. Because there are many diseases that are transmitted by mosquitoes, like dengue fever that we are familiar with.
2. **Breakage:The baby's ** is more delicate, and it is easy to appear local redness, swelling and itching after being bitten by mosquitoes, which will make the child very uncomfortable, so that he often scratches the bite site, and the child is prone to infection after scratching.
3. Affect the quality of children's sleep:Children are in the stage of growth and development, and sleep quality is very important for the healthy growth of children. When sleeping, if your child is bitten by a mosquito, it will feel painful and itchy, and it will be easy to wake up from sleep, which will reduce the quality of sleep.
In fact, there are many parents who think that being bitten by mosquitoes a few times is not a big deal, and applying some toilet water or even saliva will soon get betterYou couldn't be more wrong to think so!
The mosquito can leapfrog all ferocious species in nature and rise to the top, not because of its bouting and criesMore importantly, they are the transmitters of many diseases
01 Malaria transmitted by Anopheles mosquitoes.
Anopheles mosquitoes, commonly known as malaria mosquitoes, suck the blood of people with malaria disease and also suck the malaria parasite (the source of malaria) into the body. When they bite again, the malaria parasite is injected into the body of the bitten person from the mosquito's mouth.
After 10 days, the malaria parasite begins to appear in the blood vessels close to **. They multiply in the patient's red blood cells, forming a large number of small protozoa that destroy the red blood cells and release a toxin.
Each small malaria parasite invades other red blood cells and continues to multiply, causing more and more malaria parasites and toxins in the patient's body, causing chills and fever.
02 Aedes mosquitoes transmit epidemic Japanese encephalitis and dengue fever.
Aedes mosquitoes, also known as black and white markings, mainly transmit Japanese encephalitis and dengue fever. In most parts of the world, mosquitoes are a serious public health problem.
It is estimated that about 700 million people are infected by mosquitoes each year, and 1 in 17 people die from mosquito-borne diseases. Especially in the tropics, multiple infectious diseases are often transmitted to humans by mosquitoes.
According to statistics, mosquitoes have become the number one natural enemy of humans, although they are small, but they are very lethal700,000 people die every year from mosquito bitesThis figure is much higher than the number of poisonous snakes, dogs, lions, tigers, leopards and other fierce beasts hurting people, becoming the deadliest animal to humans.
It's hard to imagine that this little thing that we can slap to death kills more people every year than any other animal!
It is no exaggeration to say that mosquitoes are found in nature"Killing machines".Ah, people have to be guarded against!
In order to keep the family and children away from the threat of mosquitoes, it is the top priority to do a good job of mosquito prevention and repellent!
When a child is bitten by a mosquito, here are some things you can do to relieve the symptoms:
1.Wash the bite site:Gently wash the bite site with warm water and soap to prevent bacterial infection.
2.Cold compress:Applying ice or a cold washcloth to the bite site can reduce pain and itching.
3.Use ointments or lotions:Ointments or lotions containing antihistamine ingredients can be used, which can reduce itching and swelling.
4.Avoid scratching:Try to avoid scratching the bite site to avoid damage** and infection.
If your child has severe symptoms such as shortness of breath, dizziness, swelling of the throat, difficulty breathing, etc., they should seek medical attention immediately.
1. Mosquito repellent
Mosquito repellent needs to be applied to **, and wounds, inflammation, etc. cannot be applied. The effect is not long-lasting and needs to be applied repeatedly.
2. Electric mosquito swatters
Electric mosquito swatters are used to kill mosquitoes by physical means, and if they are not used properly, they are not carefully swatted, and if there are missed mosquitoes, they will not sleep well if they buzz overnight. Not only insomnia, but also affect work. It needs to be plugged in, and if you accidentally start a fire. The effect will not be obvious.
Although the insecticide is simple and convenient to use, it has a long breathing time and needs to seal the room, so it is not suitable for this kind of product if there are children at home. Toxicity and harm.
If the insecticide is used with an electric mosquito swatter, it will be directly **, and the safety hazard is really too great.
Mosquito coils or electric mosquito coils: The main ingredient is a chemical carcinogen such as pyrethroid chemicals and the pesticide DEET, which affects respiratory health.
Mosquito repellent water: The main ingredients are insect repellent ester and alcohol, which is easy to irritate the skin.
Toilet water: The main ingredients are flower oil and alcohol, which are flammable and irritating to the skin, so infants should use with caution!
Mosquito nets: Troublesome and stuffy! If you don't pay attention, mosquitoes will get in.
The above experiment isMosquito coilsWhen you encounter a sofa pillow at home, it quickly ignites ** flames! Security risks are like a "ticking time bomb".
For mosquito repellent, the product recognized by Jiu** is mosquito coils, but we still have to remind everyone that when using mosquito coils, we must pay attention to fire prevention!
After the mosquito coil is lit, although there is no open flame, there is only a small burning point, but this kind of burning point has a lot of potential safety hazards. There is no open flame, but it can continue to burn without extinguishing, and this smoldering characteristic is similar to that of a cigarette!
Mosquito coils are mainly composed of sticky wood powder, charcoal powder, and medicines, and when smoldering,The maximum temperature of the fire point can reach 700 -800, and the high temperature can reach 130 cm around the fire pointIt is enough to ignite combustibles such as mosquito nets, cotton cloths, sponges, clothes, paper, etc., which have a low ignition point, and cause a fire.
If mosquito coils just have"Flammable hazard".In fact, as long as you pay attention to it, it's fine, but in recent years, there have been many mosquito coils"Is it toxic or not".The experiment has made a difference in our attitude towards mosquito coils!
It is estimated that the amount of particles released by lighting a roll of mosquito coils is about the same as burning about 100 cigarettes, and the ultra-fine particles released can enter and remain in the lungs, which may cause asthma in the short term, as well as some compounds that will irritate the upper respiratory tract, which will poison the human nervous system!
Therefore, the biggest nemesis of mosquitoes is not mosquito coils! If you light mosquito coils, the mosquitoes may be fine, and people will be fine!
In order to ensure the insecticidal effect, the content of pyrethrin in mosquito coils must meet a certain standard, which is safe for the average adult, but there is a risk to the elderly, pregnant women, and infants and young childrenThe ultrafine particles released during combustion may irritate your baby's respiratory tractIt causes uncomfortable symptoms such as dry itching of the trachea, cough, and nausea, and long-term exposure may cause symptoms such as dizziness, discomfort, nerve excitement, or paralysis.
After a period of use, mosquitoes can also become resistantMosquito coils are of little use.
So, mosquito coils are not the best way to repel mosquitoes!
You can't hide from it in your life
Disgusting and scarypeopleWhat are the animals?
I guess it must beBugger!
Especially in the spring and summer seasons.
ExactlyBug reproductionSeason.
Cockroaches, ants, fleas, mosquitoes, flies, flying insects
Every one of themAnnoying, scary and disgusting!
The bugs are smallExtremely harmful!
They're all over itBacteria, toxins
News of being bitten into the hospital by insects abounds
Especially at homeChild、Old man
They have low resistance,More susceptible to bugs
How many families just becauseI don't pay attention to bugs
Loved ones are hurt, disaster and wealth are ruined
A large number of bugs lurk in your house to breed
GapsDark corners, cabinets, kitchens, toilets, ......
For example, cockroaches, hot knowledge: when you find a cockroach, it means that there is a nest of cockroaches nearby! When you step on the female cockroach to death, the baby cockroach will still hatch!
The 40 kinds of bacteria on their bodies are quite harmful to the human body。The elderly and children have poor resistance, and if they are accidentally contacted, headaches, brain fever, and ...... running to the hospital are indispensable
But deworming is not so easy, and I have tried various insecticides, potions, cockroach medicines, sticky boards, allEach has its drawbacksInsecticidal spray: It is highly toxic, harmful to the human body if inhaled, and the liquid left over from spraying is difficult to degrade and will persist; VariousPills, glue bait: Toxic chemicals, afraid of being used by children to play with and eat by mistake; Sticky board: It is not easy to stick to insects, and it is easy to stick to people
