Let's talk about popular science first: Why is it swollen when bitten by mosquitoes? Actually, it should be said that it was bitten by mosquitoes. Mosquitoes cannot open their mouths, so they don't bite the skin. In fact, they pierce people's skin with six needle-like structures, and these probes form the center of the mouthparts for eating. These oral needles suck blood just like blood needles; Mosquitoes also excrete saliva containing anticoagulant to prevent blood coagulation, so that they can be safely eaten. Mosquitoes ate, drank and drifted away, leaving behind an itchy and swollen bag. After the arrival of summer, mosquitoes breed, especially in the rainy season, and mosquito larvae-multiply in large numbers in floods. Mosquito bites make it difficult for people to fall asleep and spread diseases. But it is not easy to eradicate mosquitoes completely, and being bitten by mosquitoes is inevitable. When mosquitoes bite, the mouthparts will secrete an organic acid-formic acid, and its chemical composition is HCOOH. Female mosquitoes suck blood in order to get protein in the blood to nourish the ovaries, so the saliva of female mosquitoes will secrete an organic acid similar to anticoagulant, so that the blood will not coagulate, but the organic acid left on human skin is a foreign body, and some people will have allergic phenomena, such as itching and swelling. The prescription for relieving itching is 1. At home, you can use thick soap to relieve itching quickly, or you can use soap dipped in water to apply it to swollen places. The reason is the sodium salt of higher fatty acids in soap. Such as: C 17H35COONa. The sodium salt of this fatty acid is alkaline (containing OH-) after hydrolysis, and the formic acid aqueous solution contains H+. Because OH- in soap water and H+ in formic acid neutralize into H2O, it can quickly eliminate pain and itching. 2, apply some ammonia to relieve itching, the principle is the same as above. 3. If the bite is itchy, you can play it with your fingers first, and then apply toilet water and wind oil. 4. Applying or brewing the itchy place with salt water can soften the lump and effectively relieve itching. 5, you can use the juice in aloe leaves to relieve itching. When you are red, swollen and itchy after being bitten by mosquitoes, you can cut a small piece of aloe leaf, break it after washing, and rub it a few times at the red and swollen place to reduce swelling and relieve itching. 6. Applying tiger balm and salt can make local anesthesia, relieve nerves and relieve itching. 7. After grinding aspirin pills, applying water to the wound also has anti-inflammatory and detumescence effects. 8. If you are sensitive to mosquito bites, take an antihistamine before going out. Recently, Finland reported that antihistamines can block immune response and reduce itching and swelling caused by mosquito bites. However, the side effect of antihistamines is that drivers want to sleep and avoid taking them. I strongly disapprove of netizens taking antihistamine western medicine because they are afraid of mosquito bites, and I strongly disapprove of suggesting that everyone take western medicine easily because they are afraid that mosquito bites will itch, which will mislead everyone's health! 9. As long as you are willing to change the diet of alkaline vegetables, your body and blood are slightly alkaline. Mosquitoes not only don't like to bite, but they don't itch too much even after being bitten! If you bite, you can apply your own slightly alkaline saliva to the mosquito bite, which can also stop itching! 10, break off a garlic clove, and apply a mosquito-bitten bag on the cross section.

This water-soluble vitamin has no side effects. Excess ingredients are completely excreted and will not be stored in the human body. 13. Soak two pieces of Illicium verum in the seasoning in a warm washbasin and bathe with its water to keep mosquitoes away. 14. Burning dried orange peel indoors can replace mosquitoes, repel mosquitoes and eliminate indoor odor. Wear light clothes. Attention, everyone! Aedes mosquitoes (also known as spotted mosquitoes) like to park on black clothes. So in hot summer, everyone should try to wear some lighter clothes. Wear as many socks as possible. Many people like to wear shoes barefoot in summer, but they don't know that after wearing socks, mosquitoes feel that people's skin humidity is reduced, and the volatiles on the skin surface are reduced, which will reduce bites. 17, you can't catch it after being bitten. If we are bitten by mosquitoes, we will catch them at once. However, after scratching, the tissue fluid and lymph in the skin ooze out and swell into a bag, which will become more and more itchy and will not fade easily. This is how the "red bean leg" wrapped in a red envelope was caught. If you insist on not grasping, the itching will obviously subside after 10 to 15 minutes. 18. Mosquitoes like to park near the window sill before dusk, and they like to park on dark objects on the indoor surface after nightfall. According to this rule, they will get twice the result with half the effort. 19, family aquatic plants should change water regularly. 20, when using mosquito repellent, a brand in continuous use for 2 months, for a drug to repel mosquitoes, the effect is better. 2 1, eating garlic can effectively repel mosquitoes, because mosquitoes don't like the smell of garlic secreted by human body. 22.

If you can drop a proper amount of essential balm on the whole mosquito before lighting it, the mosquito-repellent incense will not choke people, the room will be clear and the mosquito repellent effect will be good. If you can sprinkle a few drops of essential balm before entering the mosquito net, you can improve the air condition in the mosquito net and increase the mosquito repellent effect. 23. Put mosquito repellent flowers. Before dusk, put 1 indoors and put 2 pots of blooming jasmine, Milan or roses, preferably cordate telosma. The mosquito couldn't stand the smell of these flowers and ran away. 24. Install orange light bulbs indoors, because mosquitoes are afraid of orange light, so they can have a good mosquito repellent effect. 25. Rub the dried Folium Artemisiae Argyi into a rope, light it and put it indoors. Smoke can repel mosquitoes. Burning dry tea leaves can drive away mosquitoes. 27. Put 35 ml of sugar water or beer in an empty wine bottle on the table or in a room with many mosquitoes. When mosquitoes smell sweet wine, they will inject it into the bottle and be stuck to death by sugar water or beer. 28. Close the doors and windows, put a basin in front of the window and add some water mixed with washing powder. The next day, there will be some dead mosquitoes in the basin. If this method is used continuously every day, it is almost unnecessary to spray pesticides to kill mosquitoes. There will be fewer and fewer mosquitoes. Why can soapy water kill mosquitoes? Because washing powder is alkaline, mosquitoes should not grow in alkaline water, but there are spices in washing powder, which will make female mosquitoes mistakenly think that there is food and lay eggs in it. So as to achieve the effect of killing mosquitoes. 29.

When using mosquito repellent to repel mosquitoes, it is best to place a plate of mosquito repellent with a plant height of about 30 cm and more than 40 pieces in an indoor area of about 15 square meter. In the beautiful plant world, there are many flowers and plants that are both ornamental and can drive away mosquitoes! Below, let's take everyone to meet! Evening primrose, also known as cordate telosma, is native to tropical America. Leaf blade cordate, margin pilose. Every summer and autumn, clusters of yellow-green bell-shaped flowers will bloom in the axils of leaves, and when they go to the treetops in the same month, they will float out bursts of fragrance, which makes mosquitoes afraid. It is a good mosquito repellent. Lavender is a blue-purple flower. Originated in the Mediterranean, it likes to be dry, and its flowers are like wheat ears, which usually bloom in June. Lavender itself has insecticidal effect. People usually put sachets made of lavender in the cupboard, and some put them in the bedroom to repel mosquitoes. Nepenthes is a typical insect-eating plant with strange leaves and a long round "insect-catching bottle" hanging at the top. The bottle mouth has a lid that can be opened and closed. There are dozens of pitcher plants, and different kinds of insect traps are different in shape, size and color. Nepenthes can be used as medicine to treat hepatitis, stomachache, hypertension and cold, and it is also an expert in mosquito catching. Geranium geranium is full of flowers and can adapt to all parts of the country. In the hot season, place it in an outdoor cool environment; Watch it in a bright room in the cold season. Geranium has a unique smell that makes mosquitoes and flies run away. Qilixiang is a small shrub that is evergreen all the year round.

Touch its leaves, you will feel a thick sweet fragrance, which has a good mosquito repellent effect. Cordyceps sinensis is a kind of compositae herb, which can grow to 1 m high, with small yellow flowers and hundreds of flower heads. There is mucus around each flower head, just like five little fingers sticking out, which is very interesting. As long as there are small mosquitoes on it, they will be stuck. After that, the insect will be slowly digested by it as its growth nutrition. If the dust is digested without a trace after a few days, put a pot in the pot to catch mosquitoes and vacuum at home. The lemon twist fragrance emitted by mosquito repellent herbs is mainly citronellal, citronellol and other aromatic natural essential oils with mosquito repellent effect, so as to achieve the purpose of mosquito repellent. According to the characteristics of mosquito-repellent weeds, the following points should be paid attention to when maintaining: 1. Mosquito-repellent weeds are better maintained than ordinary flowers and trees, and have stronger resistance to organic fertilizers, and their life cycle can reach more than 8 years. Usually pay attention to more ventilation and more light to keep the soil loose and moist. When not in use during the day, it can be placed on a bright and ventilated windowsill or balcony, and it is best to receive one or two hours of direct sunlight every day. Second, when mosquitoes appear at night, put mosquito repellent in the center of the room. Before use, spray water evenly on the front and back of the blade with a special small sprayer (no water spray, the effect is not good), and spray it again half an hour later. Third, in the process of use, it is best to change to a larger flowerpot. Mosquito repellent has a well-developed root system, which can absorb more organic matter from flowerpots, but we should also pay attention to keep the soil moist frequently and water it once a week or so. It should be noted that mosquito repellent only has mosquito repellent function, but not mosquito repellent function. In order to prevent mosquitoes from adapting, the room should be thoroughly disinfected two days before use. This will keep mosquitoes out. In summer or summer vacation, especially in rural areas, children have a good chance to get in touch with nature. As parents, we should educate our children to pay attention to insect prevention. Avoid snakes: In summer, all kinds of snakes often appear in the fields or grass. Snakes generally don't take the initiative to attack people. After encountering a snake, the child should leave gently and don't tease at will. Toads are poisonous: whenever night falls, there are often many toads jumping in the yard and fields. Some children don't understand toads. They think it's fun and go to catch toads. As a result, soon after catching toad, many rashes broke out on the child. Toads are also called toads. They secrete a white venom, so children should not touch it. Don't poke a hornet's nest: wasps often nest under windows, corners of doorways or branches. Naughty children will find sticks and fiddle with hornets' nests, which is very dangerous. In order to protect their nests, wasps will fight back against any invasion. Wasps can sting swollen people, and they will sting people to death when they meet poisonous wasps. In addition, some bugs can do harm to people. For example, scorpions have thorns on their tails, which will sting people; The centipede's front foot has poisonous glands that are harmful to people; Leeches will suck people's blood when they are attached to people. The stinging caterpillar is poisonous and so on. Anti-mosquito Camping in Summer Camp When you travel or camp in summer camp, it is inevitable that you will be bitten by mosquitoes. In most cases, being bitten by mosquitoes will not cause serious consequences, but if you are allergic to a certain mosquito toxin or bitten by a large number of insects, it may be life-threatening. Therefore, correct preventive measures should be taken. Fence isolation method: prepare a bag of fresh lime in advance, and spread a layer of lime fence outside the campsite, leaving no gaps and not spreading it on floating grass; Or dry the edible ginger and grind it into powder, and scatter it around, and use the peculiar smell released by them to form a safety belt to isolate mosquitoes and snakes from the circle. Incense-expelling method: after the mosquito-repellent incense 1 ~ 2 sold in the market is lit, it is placed in the upwind of camping, or the bottle (box) of toilet water, wind oil essence and cooling oil is opened and placed in the upwind; You can also spray wind oil and cool oil directly on shoes and socks (once every two hours), or slice edible garlic and apply it on shoes and socks and pants to prevent mosquito bites.

Pregnant women are more likely to be bitten by mosquitoes. It is advisable to use "green method" to prevent mosquitoes. After pregnancy, Xiaoli felt more vulnerable to mosquito attacks than before, which made her very annoyed and puzzled. The research of British experts unveiled the mysterious veil for Xiao Li. The researchers found that pregnant women were bitten by mosquitoes twice as often as non-pregnant women. Experts speculate that women's breathing ability increases by 265,438+0% during pregnancy, and the smell of human breath is one of the main reasons for attracting mosquitoes. Because mosquitoes are the main vectors of some diseases, including malaria and Japanese encephalitis, pregnant women should pay more attention to preventing mosquito bites. Pregnant women should not use chemical mosquito killers and harmful mosquito coils to prevent mosquito bites. The active ingredients of most mosquito-repellent incense are pyrethroid insecticides. The smoke produced by burning mosquito-repellent incense contains extremely fine particles and chemicals, which is harmful to pregnant women and fetuses. Therefore, pregnant women advocate "green methods" to prevent mosquito bites: 1. Use mosquito nets or screens to keep mosquitoes out. Mosquito nets can not only avoid mosquitoes but also prevent wind, absorb falling dust and filter the air, which is especially suitable for pregnant women and children. Screen windows let fresh air into the room and harmful smoke out of the room. 2. Put one or two pots of blooming cordate telosma, jasmine, Milan, mint or rose in the bedroom. Mosquitoes can't stand their smell and will avoid them. 3. Install an orange light bulb indoors or cover it with transparent orange cellophane. When the light is turned on, mosquitoes will run around for fear of orange light. 4. Fill an empty wine bottle or cup with sugar water or beer and put it in the shade. When mosquitoes smell sweet wine, they will get into the bottle and be stuck to death by sugar water or beer. 5. Eating garlic raw and the garlic excreted by sweat after physiological metabolism will produce an odor that mosquitoes dare not approach. 6. Clean up the places where mosquitoes are easy to breed. Still water and clogged sinks are breeding grounds for mosquitoes. Mosquitoes will lay eggs in still water and soon hatch into larvae. Therefore, clearing the stagnant water in front of and behind the house can effectively prevent the breeding of mosquitoes. 7. Try to wear light-colored clothes, such as yellow or white. Because dark clothes are easy to be bitten, such as dark blue, brown or black. 8. Frequent bathing can reduce the sweat smell secreted by the human body, and mosquitoes are not easy to bite. 9. Spraying toilet water on the collar and cuffs can also prevent mosquito bites. 10. Skillfully use the refrigerator. When the compressor on the back of household refrigerator works, its shell temperature is usually 45 ~ 60℃, and it is heated evenly. If you buy a special mosquito killing tablet for electronic mosquito killer on the market, put it on the compressor shell of refrigerator at night and use the remaining hot evaporation tablet, you can achieve good mosquito killing effect. Not only can it save a sum of money, but it is also very convenient to operate. Emergency treatment once bitten by mosquitoes, appropriate emergency treatment should be carried out to minimize the harm of venom to human body. Bite by poisonous mosquitoes: You can repeatedly apply cool oil, wind oil or safflower oil to the affected area. If there is a sterilized triangular needle, you can also puncture and bleed first, and then apply the above drugs after squeezing out the yellow poison, which is better. Being stung by bees: bees sting the poison sac, so carefully pull out the sting with tweezers to prevent the poison from pressing into the skin, and then squeeze the stung part until bright red blood flows out; Then apply baking soda water to the wound. Bite by wasps and ants: they don't leave stings, but only apply them locally with dilute ammonia to neutralize the venom. Ticks suck blood: never pull hard with your hands, because it is easy to break, leaving your head in the skin will cause infection. You can burn its back with cigarette butts or matches, and it will loosen itself; Or use cooking oil and engine oil to drip on him, block his respiratory tract and suffocate him. Bite by poisonous snake: immediately ligate the upper part of the wound to prevent venous blood from flowing back and reduce the spread of venom. Ligation should be completed within 1 ~ 3 minutes after the bite, and rubber bands, ropes, cloth strips, handkerchiefs and other things can be used. The main points of ligation are: biting the finger, stabbing the root of the finger, biting the calf, tying it above the knee joint, biting the forearm and tying it above the elbow joint. The tightness of ligation should be to prevent lymphatic and venous reflux, and a small amount of arterial blood should pass through. It is basically appropriate to feel nervous at the ligation place. Pay attention to relax ligation for 2 ~ 3 minutes every 15 ~ 30 minutes to prevent ischemic necrosis of the distal limb. After ligation, the wound and surrounding skin should be washed repeatedly with soapy water, Leng Cha or clear water, and 2% hydrogen peroxide or 1: 5000 potassium permanganate solution can be used when conditions permit. But don't wash the wound with alcohol or wine. After washing, the wound is enlarged and detoxified, and the skin is cut longitudinally or transversely along the direction of fangs marks with a knife or blade. Remember not to go too deep, only under the skin, but avoid veins. If there are any fangs left, we should pick them out and apply medicine to the enlarged wound. The easiest way is to suck the wound with your mouth, vomit while sucking, and then rinse your mouth with clear water. However, it should be noted that the oral mucosa of the sucker must be free from injury and ulcer, and the teeth are free from patients, otherwise it will be easy. After the venom is sucked out, the wound should be covered with seven layers of sterile gauze and moistened, which is conducive to the continuous outflow of venom. After on-site ligation and detoxification, they should be sent to the hospital for treatment in time. If a poisonous snake is bitten to death, you should take the dead snake to the right medicine.

The second category: "physical" weapon mosquito nets can not only avoid mosquitoes and wind, but also absorb falling dust and filter the air. The electric mosquito swatter forms a layer of power grid on the net surface through electric energy. After hitting mosquitoes, electricity passes through their bodies and burns them to death. Mosquito killer mosquito trap lamp uses the phototaxis and sensitivity of mosquitoes to special wavelengths to induce mosquitoes to touch the net surface and be instantly burned by high-voltage electricity. Mosquito killer should be placed above the knee and not more than 180 cm from the ground. When using the mosquito trap lamp, all other indoor light sources should be turned off to avoid affecting the mosquito trap effect. Adding some water and vinegar to the insect collecting box of the mosquito catching lamp has better mosquito catching effect.
