Flower mosquitoes mostly bite people outdoors, but they also bite people indoors, and they suck blood throughout the day. The peak activity mostly occurs in the morning 1-2 hours before sunrise and 2-3 hours before sunset. In addition, this mosquito also has the characteristic of multiple blood meals, and as time goes by, the rate of multiple blood meals increases.
Habits of Mosquitoes
Mosquitoes generally start to go out in April and reach the peak of activity in mid-to-late August. When the climate gets colder in autumn and the temperature drops below 10 degrees Celsius, mosquitoes will stop breeding and enter hibernation until the second year. After awakening in the spring, they come out to harm people again.
The most suitable temperature for mosquitoes is around 30°C. They cannot tolerate it if it is too high.
Mosquitoes must find a place to live after they emerge and after sucking blood. Generally speaking, mosquitoes like to live in hidden, dark and poorly ventilated places, such as under the bed, behind cabinets, behind doors and wall cracks in the house, and outdoors in grass and caves. , cellars, bridge openings, stone crevices, etc.

How do mosquitoes find you?
Although mosquitoes have two big eyes, their eyesight is actually very poor, but the fact is that mosquitoes can always find you. Even if they only have one head exposed when sleeping, they can bite you accurately.
is not visible, it can be seen in other ways.
① carbon dioxide
Sacrificing vision, the mosquito gains an extremely sensitive sense of smell, but it does not use its nose, but its antennae. The antennae of mosquitoes can accurately distinguish the level of carbon dioxide concentration. When we sleep, we can always hear the "squeak" of mosquitoes (the sound made by vibrating wings). That is, they preferentially find the location with the highest carbon dioxide concentration. We head.
Someone once did an experiment and put a piece of dry ice (solid carbon dioxide) in a room with many mosquitoes. Mosquitoes will quickly gather there, even if the lights are turned off.
② Temperature
The mosquito’s eyes have poor vision, but they can capture heat sources very accurately. Its eyes can be regarded as a thermal imager.All the other items in the room are in cool colors, but you lying on the bed are in warm colors. If not, who would bother you?
Mosquito: "If it doesn't bite you, why do you bite the table? I'm not a woodpecker!"
③ The special smell on the surface of the skin
As long as you are alive, you will sweat, and sweating will attract mosquitoes, because sweat contains acetone and octene More than a dozen ingredients such as alcohol and lactic acid are very attractive to mosquitoes.
You said, I take a shower before going to bed, my skin is very smooth and I don’t sweat at all, why are you still biting me?
Just because you think you don’t sweat doesn’t mean you really don’t. Mosquitoes can sense special smells five kilometers away. Sweat that you can’t feel is a piece of cake for mosquitoes.
Who is more likely to be bitten?
① Fat people
Obese people have high body temperature and love to sweat. Their bodies exude more amino acids , lactic acid and ammonia compounds (commonly known as sweat odor), which are temptations that mosquitoes cannot resist and will knock down every one they see.
So, if you want to avoid being bitten, lose weight quickly.
If a thin person is a meat and a vegetable in the eyes of mosquitoes, then you are probably a Man-Han banquet.
② Pregnant women and children
have fast metabolisms and exhale relatively more carbon dioxide, and are also favored by mosquitoes.
③ People who love sports
Needless to say, after exercising, people’s breathing speeds up, their body temperature rises, their heads are sweating profusely, and even mosquitoes feel like it’s the Chinese New Year.
④ People who love makeup
In order to verify the attractiveness of smell to mosquitoes, American scientists used olfactory instruments to test and analyze more than 3,900 substances. It was found that many types of hair spray, hand cream, facial cleanser and other cosmetics are unusually attractive to mosquitoes.
Most cosmetics contain stearic acid (a type of fatty acid), so people who wear makeup are also prone to mosquitoes.
⑤ People wearing dark clothes
Mosquitoes have dark tendencies, and dark clothes will make mosquitoes think that this is an ideal habitat.
Darkness is also the reason why mosquitoes come out during the day and night. They come when you turn off the light to sleep, but they run away when you turn on the light.
Tips for preventing mosquitoes
① Mosquito nets and wearing long clothes and long trousers
These are all physical ways to prevent mosquitoes, and wearing long clothes and trousers in summer is not recommended because it is very hot.
② Put soapy water in the corner
The smell of soapy water will attract mosquitoes to lay eggs. When they suck it, the alkalinity of the soapy water will neutralize the acidic substances in the mosquito's body and cause its death. The eggs laid cannot survive in an alkaline environment. .
③ Aquatic plants Change the water frequently
If you have aquatic plants at home, you must change the water frequently, otherwise in a few months, this place will become a mosquito base.
④ Temperature mosquito repellent
Mosquito incense, wind oil essence, mugwort, orange peel, etc. have special aromas that mosquitoes don’t like.
⑤ Saliva relieves itching (personal test is effective)
When bitten, there is no wind oil essence. It is very effective to wipe it with saliva. The saliva is alkaline and neutralizes the oral secretions of mosquitoes, which can quickly relieve the itching.
Why special area?
① What marks are left on your hands when you swat a mosquito?
Those are the scales of mosquitoes. rupture due to external force and form powder. The scales are one of the characteristics that distinguish Midipera from other Diptera insects. (Non-toxic)
②Why don’t you feel anything when bitten?
Firstly, the mouthparts of mosquitoes are very thin, and secondly, mosquitoes will inject some anesthetic substances into the human body's skin before sucking blood.
③Why do you have to suck blood? Isn’t it okay to suck tree sap?
In order to survive, the female mosquito's ovaries need blood to fully develop. Male mosquitoes don't have ovaries, so they don't suck human blood. After all, "eating a meal" involves risking their lives, so no one would do it.
