In the midsummer season, apart from the extreme heat, the most unbearable thing is probably being bitten by mosquitoes, but what makes people wonder is that some people can sit outdoors for a long time without being bitten by mosquitoes, and some people even use mosquito-containing insecticides. I took a bath with shower gel and carried a mosquito killer with me, but I was still bitten by mosquitoes and itchy. How is this going?
What kind of people tend to attract mosquitoes?1. Sweat easily and have a higher body temperature
Sweat is one of the signals for mosquitoes to forage, so people with more sweat are more likely to be "favored" by mosquitoes. This is because sweat contains lactic acid, amino acids and ammonia compounds, which are easy to attract the attention of mosquitoes. Strenuous exercise will increase the accumulation of lactic acid and calories in the body. In addition, there is a heated body in the tentacles of mosquitoes, which is very sensitive to temperature, and the human body with more sweat dissipates heat quickly, so it is more attractive to mosquitoes.
2. More carbon dioxide is exhaled
Scientists have discovered that a mosquito with a tentacled can actually feel the concentration of carbon dioxide 50 meters away. Therefore, people who produce more carbon dioxide are more able to attract mosquitoes. It can also be said that the faster the metabolism, the more mosquitoes are recruited. Generally speaking, people like children, larger bodies, pregnant women, and people with large lung capacity are more likely to attract mosquitoes. An African study found that pregnant women are twice as attractive to mosquitoes carrying malaria as non-pregnant women. Researchers believe that this is due to the increase in carbon dioxide, and women in late pregnancy exhale 21% more than women who are not pregnant.
3. The body has more irritating gas
The sense of smell of mosquitoes is very sensitive, especially to some more irritating gases. Therefore, those who love makeup are more likely to provoke mosquitoes than those who do not. Because many cosmetics have a lot of fragrance, which is quite attractive to mosquitoes, so when you go out in the summer evening, remember to remove your makeup.
4. People who wear dark clothes
Studies have shown that mosquitoes are easily attracted to black. The main reason why mosquitoes appear day and night is mainly due to their darkening habit. The compound eyes of mosquitoes are particularly sensitive to ultraviolet light and blue-green light. They prefer to stay in darker colors (on objects, mosquitoes do not like to bite white. Similarly, mosquitoes love to bite people with darker skin or red skin. Bright purple It is the favorite of mosquitoes. The mosquito killer uses ultraviolet light to attract mosquitoes. Black is the color of the mosquito’s resting place, which can give mosquitoes a sense of security, so it is also very attractive to mosquitoes. Therefore, wearing light-colored clothes in summer can reduce The chance of being bitten by a mosquito.
What should I do if I am bitten by a mosquito?According to disease control experts, you cannot scratch after being bitten by a mosquito. Otherwise, the tissue fluid and lymph fluid in the skin will ooze out and swell into a bag, which will make itchy more and more, and it will not disappear easily.

If the bite is very itchy, you can flick it with your fingers first, and then apply toilet water, wind oil, etc. In addition, alkaline substances can also be used to relieve pain and itching. For example, using salt water, toothpaste and garlic to smear or brew the itchy area can also soften the lumps and effectively relieve itching.

How to reduce mosquito bitesIn 2013, the World Health Organization released a map showing the ranking of animals that caused human deaths. To the surprise of many people, mosquitoes top the list, ranking first. Every year, mosquitoes cause 725,000 deaths worldwide, which is 250,000 more than the 475,000 deaths caused by human killings. This number is staggering. Therefore, it is very important to avoid being bitten by mosquitoes.
According to experts, the best and most thorough method to prevent mosquitoes is environmental management to remove mosquito breeding grounds, followed by safer physical methods such as mosquito nets, mosquito swatters, and mosquito traps; finally consider choosing mosquito coils, aerosols, and repellents. Chemical methods such as agents.
1. Clean up the environment of mosquito breeding grounds
First, let's understand the breeding situation of mosquitoes. Female mosquitoes lay their eggs in damp places or in water. The eggs will grow into larvae in the water, and the mosquitoes that grow into adults can leave the water. This is why there are sometimes inexplicable mosquitoes in the house.
Based on the growth habits of mosquitoes, we can eliminate the breeding environment of eggs and larvae by cleaning the dead corners of the home.
Check the water in the pots, floor drains, sewers, flower pots, etc. in the home, cover the water with a lid, and change the water frequently. Prevent water accumulation in floor drains, sewers, etc., and no space for mosquitoes to live; try to keep the room dry and bright, because mosquitoes like to live in a dark and humid environment. The aquatic plants in the home should be changed regularly; pay attention to close the screen windows and screen doors, and do not open the door to allow mosquitoes to drive in.
2. Physical mosquito repellent
(1) For children, the safest anti-mosquito tool is barrier type, especially for small babies. It is best to use zipper mosquito nets with good sealing performance, which reduces the chance of mosquitoes coming in and prevents babies from falling out of the bed. In addition, carefully check whether there are mosquitoes in the mosquito net before putting down the mosquito net!
(2) Take a bath often and use less perfume. Take a bath regularly to keep your skin fresh and wipe off the sweat in time when you sweat, which can reduce the attraction of sweat odor to mosquitoes. Use soap and perfume sparingly. Mosquitoes like to eat nectar. Therefore, after using perfume, cosmetics, facial cream and other floral-scented items, the probability of being bitten by mosquitoes will increase.
(3) Mosquitoes are more afraid of special smells, and some natural plants have a repellent effect on mosquitoes. For example, nightflower and wormwood, the most obvious of which is pyrethrum, has a strong repellent or even killer effect on mosquitoes. Mosquitoes also don't like the smell of lemongrass oil, citronella and geraniol.
(4) Wear light-colored clothes for outdoor sports. When you are active in places with a lot of mosquitoes, try to wear light-colored long-sleeved clothes and wear socks. This will not only reduce the exposure of human mosquitoes, but also the mosquitoes can feel the humidity of human skin decreases , The reduction of volatiles on the skin surface will also reduce bites.
3. Chemical mosquito repellent
Use mosquito coils, aerosols or repellents to repel mosquitoes: When using mosquito coils, follow the instructions to repel mosquitoes and kill mosquitoes. Place the mosquito coils in a ventilated place upwind. You can also use insecticidal aerosol to kill mosquitoes. When using insecticidal aerosol, try not to spray directly on clothes, sheets, furniture, and skin. Before spraying, store food and tableware. It is best to close doors and windows for half an hour after spraying. To 1 hour, then open the window to ventilate. Excessive spraying of insecticidal aerosol will be toxic to the human body, so you must pay attention to safety when using insecticidal aerosol at home, do not let infants and young children touch it, if you accidentally spray the liquid on the skin, wash it in time .
