A lot of little bugs also started to come out and move,
In addition to the beautiful butterflies, noisy know,
There are also many poisonous, blood-sucking poisonous insects,
For example, we are familiar with mosquitoes and fleas, which are itchy and itchy after biting and wrapping up.

———— ticks, cryptoptera
< h1 class = "pgc-h-arrow-right" > [tick].</h1>
When it comes to tick bites, many people may have heard of them, because every year there are reports of severe symptoms due to tick bites, and finally hospitalization or even death.
Ticks, also known as grass crawlers and ticks, live in forests, bushes, and some animals.
Mainly rely on blood sucking for a living, the appetite is particularly large, the original body is only the size of a grain of rice, after sucking blood can be expanded to several times, dozens of times.
Although tick bites do not hurt much, or even feel nothing, they can carry and transmit a variety of diseases. For example, forest encephalitis, Lyme disease, tick-borne typhus, Q fever and so on.
In the summer of 2010, Henan, Hubei, Shandong and other places in China successively had fever with thrombocytopenia syndrome after tick bites, and in severe cases, multiple organ failure and death occurred. It was later confirmed to be caused by a new type of Bunia virus infection, which is mainly transmitted by ticks.
What should I do after a tick bite?
Don't pull hard! Don't drag hard! Don't just squeeze it.
It can be applied with alcohol, kerosene, turpentine, or smoked with mosquito coils to loosen the mouth of ticks due to anesthesia or suffocation.
Disinfection of iodine or alcohol after the body is shedding.
If fever, headache, fatigue, local redness, swelling, and ulceration must be treated in time to the hospital.
Prevention: Because ticks are generally found in forests and bushes, and the cases of tick bites caused by domestic and foreign reports are mostly caused by forest ticks. Many forest parks have such a sign at the entrance - watch out for ticks.
Therefore, when traveling to forests, bushes and other places, do a good job of protection and try to wear long-sleeved clothes.
<h1 class= "pgc-h-arrow-right" > [cryptoptera].</h1>
Cryptoptera is very common in the south, especially on summer evenings.
Although the insects are not large, they are very toxic.
Looks like a flying ant, 0.6 to 0.8 cm.
Cryptopteryx does not come out during the day, day and night, has phototropism, and often flies in groups at night where there are lights, especially fluorescent lamps.
It breeds faster from April to September every year, and is also a time when cryptoptera dermatitis occurs.
What does cryptoptera dermatitis look like?
Cryptoptera dermatitis is not bitten out, mainly because the worm contains a strongly acidic toxin in the body from front to back.
After being slapped, the poisonous juice in the body will splash on the skin, causing burns. (It's like being poured with sulfuric acid)
Cryptoptera dermatitis, like the picture, is like being whipped by a whip, one by one erosion noodles.
How can it be treated and prevented?
Cryptoptera dermatitis is actually a kind of burns and inflammation caused by acidic venom, and the focus of treatment is to prevent infection and control the inflammatory response.
First of all, it can be rinsed with soapy water or 5% sodium bicarbonate solution;
Then: rub with topical iodine or fusidic acid cream, etc., and when erosion surfaces appear, you can use iodine volt solution or 1:5000 potassium permanganate solution to wet compresses.
If the lesion area is large, the pain is severe, there is general malaise, or the lesion occurs around the eye, you must go to the hospital in time.
prophylaxis
1. Do a good job in personal and surrounding hygiene, eliminate the breeding environment of cryptoptera; install screen windows, mosquito nets, and night screen mosquito nets must be closed;
2. Because Cryptoptera is diurnal and has phototropism, it is necessary to wear long sleeves when moving under lights or outdoor street lights at night; turn off the lights when sleeping.
3. When cryptoptera is found, do not flap directly, gently blow off, and then shoot to death.
Summer is the season of frequent insect activity and the high incidence of insect skin diseases. Among them, ticks and cryptoptera are two common poisonous insects that can have serious consequences, learn the correct prevention and emergency treatment, and spend the summer together with peace of mind.
