Therefore, if you have high fever, headache, back socket pain, muscle pain, joint pain, rash, or obvious bleeding, you should seek medical treatment in time.

The common small black mosquito is actually a Taiwanese milk that is endemic to Taiwan. Unlike mosquitoes, it may transmit diseases. Little Black Mosquito is considered a harassing insect and does not carry infectious diseases. However, the power of the small black mosquito is amazing. Cai Yishan said that small black mosquitoes are collective attacks and will suck blood several times. Often, when they encounter it, they will get red bean ice on their legs. The number is amazing. Everyone has different reactions after being bitten. Slightly symptoms are red, swollen and itchy, which may cause allergies.
From to 2 pm, the peak hours of , try not to get close to places where small black mosquitoes such as moss and blue-green algae.

3. Flea
If you find that most of the bites you are bitten below the calf, and there are usually rashes arranged in a straight line or triangle, it may be a masterpiece of fleas, because the height of fleas bounce is about about the height of the calf. When biting you, you will not only bite one place, so there are usually 2 to 3 rashes at a time, with a spacing of about 1 or 2 cm, about the same size as a coin of 10 to 50 yuan, and the size is uniform.
bites by fleas can be treated with oral antihistamines and topical ointments. However, if fleas appear in the home environment, you must do a thorough job of deworming in the environment, or seek assistance from a professional deworming company.
Even if you don’t have pets at home, it may be that there are fleas hidden on nearby stray cats and dogs, which will affect you. Liu Pengchi, attending physician of the medical department of Xinguang Hospital, pointed out that since fleas are parasitic insects that reliably survive by absorbing blood from animals, fleas may appear in places where there are animals. In addition, fleas also like dark and humid environments.

4. 回回回回回回
回回回回回 are small black beetles with black and yellow ring patterns on the abdomen. If you kill it with a slap, its venom will cause erythema on the skin, which may be straight or a whole piece, burning and tingling, and blisters.Although crypto-winged insects do not bite people, their body fluids include crypto-winged insects, which can stimulate the skin. Liu Pengchi pointed out that if you accidentally touch or slap it, the skin may become inflamed, blisters and local ulcers, and in severe cases, it may also turn into cellular tissue inflammation.
Therefore, if you find a crypto-winged insect, you must not slap or capture it with your hands. It is recommended to use paper or fan, or blow lightly to ask it to leave. If you are really attacked by the crypto-winged insect body fluid, you should immediately rinse with a lot of water and ice, and seek medical treatment. "The symptoms will usually be improved with antihistamines and antibiotics," Liu Pengchi pointed out.
Hidden-winged insects are active in summer and like to live in paddy fields, grasses, and woods. Whenever they are harvested, weeded or rained, their habitats will be destroyed, and they will come out to move. In addition, the crypto-winged insects are phototaxis and small in size, so they may enter the room through the screen window. Therefore, it is best not to turn on the lights in the room, and you can hang a mosquito net. It is also recommended to check whether there are insects on the bed sheets before going to bed.

5. Chicken mites
Liu Pengchi pointed out that after being bitten by chicken mites, the saliva of chicken mites will cause necrosis of epidermal and dermal cells, forming a crater-like eschar that does not hurt. It is worth noting that chiggers may carry rickettsia bacteria and can contend with scrub typhus . If not properly treated, the mortality rate is as high as 60%.
The initial symptoms of scrub typhus are easily confused with colds, such as fever, sore throat, cough, muscle aches, joint pain, etc. The incubation period is about 1 to 2 weeks. After the onset, high fever may occur for several consecutive days, accompanied by severe headaches, and a dark red rash appears on the torso and spread to the limbs. Liu Pengchi pointed out that usually after the Qingming Festival holiday, there will be more patients with scrub typhus, because chiggers like to hide in the mountains and grass, so if you have fever symptoms after , you cannot rule out the possibility of scrub typhus. You can take the initiative to explain it during the diagnosis and provide doctors with reference.
If you want to avoid being bitten by chiggers, remember to find that when you are at risk (mountain forests, abandoned farmland, grass), you can wear light-colored long-sleeved clothes, gloves and long boots, etc.; apply mosquito avoidant or anti-mosquito agent approved by the Ministry of Health and Welfare to the clothes and areas exposed to the skin, and take a bath and change all the clothes quickly after the activity.

6. Avian mites
Many people can't tell whether they are bitten by bird mites or fleas. You can observe the location of the bites. The location of the bites of the bird mites is more special, and most of them will be distributed at the intersection of clothes, chest and abdomen, underarms or the edges of underwear, which is different from fleas on the limbs.
Avian mites are ectoparasites of wild birds and poultry and survive by sucking bird blood. Therefore, if there are birds building nests by the window or on the air conditioner, you should be especially careful about the bird mites crawling into the room. If you want to prevent bird bites, the most important thing is to drive away birds or nests near your home. In addition, do not dry clothes or quilts in places where birds will appear, otherwise the bird mites may run to the clothes.
However, Cai Yishan also specifically reminded that two people with the same type of mosquito bite may also have different reactions. Therefore, in most cases, doctors may not be able to determine which kind of mosquito bite from the appearance of the patient's wound, or consider individual differences. What should I do if
is bitten by mosquitoes? Experts revealed a good way to relieve itching at home
"Basically, the principles of handling mosquito bites are similar," Cai Yishan pointed out that if people are bitten, they can effectively relieve itching and reduce swelling at home by ice to avoid continuous itching, which can easily scratch the skin, cause infection, and even cause cellular tissue inflammation.
The mosquito ointments on the market are roughly divided into three categories--antihistamines, steroids, and various ointments containing ingredients such as mint, camphor, and cloves. When is very itchy, use ointment containing antihistamine components to have a good anti-itchi effect as soon as possible. However, if you are bitten by a relatively powerful black mosquito, or if it is difficult for young children to restrain their itching, you can use a steroid-containing ointment to prevent itching from being more obvious, and it can quickly reduce swelling.
"Many people will use "Little Nurse" ointment or panacea after being bitten, but the effect is limited. Mostly, coolness is used instead of itchy sensation. Applying ointments containing urea and salicylic acid (not applicable to patients with broad bean disease) may have a more anti-itchi effect," said Liu Pengchi, who usually uses alcohol-like ointment to treat medical treatment to inhibit inflammation and achieve anti-itchi effect.
In addition, many people are also worried about the problem of scars left after being bitten by mosquitoes. Cai Yishan said that many people complain that after being bitten by mosquitoes, red bean ice will appear in , but in fact, this is a pigmentation caused by an inflamed reaction. Generally speaking, it will gradually fade after 3 to 6 months.
Doctors also reminded that if you want to go to the suburbs and want to avoid mosquitoes, the best way to wear long sleeves and long trousers. It is best to choose longer socks, wrap the legs of the pants, and wear them with a wide-brimmed hat, wrap the whole body tightly, so that there will be no gaps to get drilled. In addition, it is recommended to wear light-colored clothes, which not only does not absorb heat, but also reduce the risk of being "loved" by mosquitoes. However, it is really difficult to achieve this in the hot summer. You can also choose anti-mosquito liquid, but the effect is relatively limited.
