Encyclopedia of common biting insects in summer

It's getting hotter and hotter, and all kinds of insects crawl in and out. I was stung by a bee when I was traveling with my best friend, and I met a paederus when I was playing! Babies who love to travel and climb mountains must be careful of the bites of various poisonous insects.

A guide to common poisonous insects in summer is presented to you!

First, tick-tock:

Mite often appears in grass, plants or animal fur, and it is an insect that we are easily exposed to in summer. Although the tick has the word "insect" in its name, it has nothing to do with insects because it is an arachnid.

The blood most commonly sucked by ticks is lost to cats and dogs, because they like to drill around in bushes or grass. Of course, we are not immune, so when you leave the grass or bushes after playing in the country, you must remember to check your clothes and skin. When a tick bites a human body, it secretes an anesthetic toxin, which is often difficult to detect when bitten. After being bitten, there may be only bite marks, and in severe cases, blisters and nearby lymph nodes may appear.

After being bitten by ticks, you should first carefully check whether there are bugs attached to your skin. If there is no worm, the skin is only slightly red, swollen and itchy, and an antipruritic and anti-inflammatory ointment can be used externally. If there are bugs, don't shoot them. Flapping may cause the beak of ticks to break and cause infection. You can apply vaseline and paraffin oil to the head of the tick to isolate the air around the tick and gently pull it out with tweezers. If you can't handle it yourself, please go to the hospital at once.

Second, paederus

Paederus is also very common in life, whether in the fields, in the noisy cities, or even between hides.

Paedelweiss is a small black ant flying insect, which lives in wet and dark places during the day, flies in groups in lighted places at night, and can fly from windows to bright rooms. When paederus flies around indoors and crawls on the skin, we may feel itchy or foreign body sensation in our sleep, and scratching or patting with our hands will destroy the insect body. Within a few hours, the venom will be released, local redness and itching, and gradually a burning sensation. If you come into contact with the venom of paederus venosus, you can immediately clean the damaged skin surface with alkaline solution such as clean water or soapy water, and seek medical advice promptly after neutralizing the acidic venom.

Third, tsutsugamushi disease

Tsutsutsugamushi disease mostly lives in humid grasslands and forests, and is active in spring and summer. Especially in the early morning and evening after rain, it is a dangerous period of tsutsugamushi disease activity.

Tsutsutsugamushi disease is almost invisible to the naked eye, but it is badly bitten, and often appears in soft and difficult-to-find parts of the skin, such as armpits and groin.

Tsutsutsugamushi disease is often characterized by itching, eschar or ulcer, fever, rash and swollen lymph nodes. In severe cases, it can cause complications such as meningitis, myocarditis, septic shock and even death. If you have a high fever for a long time after field activities, you should be alert to tsutsugamushi disease and seek medical advice as soon as possible.

Four. Spiny caterpillar

Spiny caterpillars are the larvae of spiny moths, and there are many kinds. People usually call them "hot seeds" and "hot seeds". When they are stung by venom, they will feel burning pain.

After the stinger of the caterpillar pierces the skin, it will feel itchy and burning at first, and it will itch outside and hurt inside after a long time. There is a big pimple in the center of the stab wound or a big rubella in soybeans, and there is edema and erythema around it. After 6-7 hours, the edema erythema subsided, leaving a central papule.

In addition, there are cases of itchy skin, and skin pain will occur repeatedly when scratching or touching the skin. Papules will turn into wheal-like lesions, which will take about 1-2 weeks to fully recover, and occasionally blisters will appear.

If you are stung by a caterpillar, you should repeatedly remove the poisonous hairs on the rash with adhesive tape or transparent tape as much as possible, and wash the part with soapy water or alkaline aqueous solution in time to neutralize the toxin. If the symptoms are serious, seek medical advice promptly.

Five, midges

This insect is smaller than sesame and looks like a black spot. Many times, people don't know that they have been bitten, and when they feel it, their skin is itchy.

Midges are relatives of mosquitoes and usually nest and fly in the air. Because after being bitten by midges, the symptoms are similar to those of mosquito bites, which also leads many people to mistakenly think that they are bitten by mosquitoes, but midges are much more serious than mosquitoes.

Plaques after biting by midges are large and appear in large numbers. Therefore, if a large area of "mosquito bag" suddenly appears on the body, it is likely to be dry, and edema is very obvious after biting midges, which may be accompanied by symptoms such as inflammation and blisters. After being bitten by midges, it itches more than mosquito bites. In severe cases, papular urticaria may occur, and toilet water and essential balm have little effect. The symptoms of redness and swelling will last for several days, which is difficult to heal. After the symptoms disappear, black spots may appear and it will take some time to return to normal.

After being bitten by midges, disinfection with iodophor or alcohol can avoid wound infection and help to reduce swelling and relieve pain. If there is obvious inflammatory infection, you need to cooperate with your doctor to use anti-inflammatory drugs, such as erythromycin ointment or moxifloxacin ointment.

How to prevent being bitten:

When traveling in the wild, it is best to stay away from areas where ticks live (such as bushes where ticks hide).

Wear light-colored clothes before going out, pay attention to the "five tights" (two cuffs, two trouser legs and two necklines) and put a scarf around your neck.
