But there are always some special bugs that can't be provoked, shoot it to death but hurt the enemy a thousand, self-damage tens of thousands, go out in addition to doing a good job of protection, pay attention to sun protection, but also have to control their hands at all times, and also have to know how to deal with them, so as not to make a wave of operations worse.
A tick
Ticks, also known as "ticks", are vectors of various diseases, have a sensitive sense of smell, can smell people or animals from a few meters away, and wait for the opportunity to suck blood in advance.
After being bitten by ticks, people will have different inflammatory reactions in 24 to 48 hours, and even some ticks will inject toxins that paralyze nerves, causing people to die from the invasion of nerve centers (more children, more foreign reports).
Ticks can't shoot, can't pull out, because forcibly pulling out will make its suction vessel (prosthesis) broken in the skin, so how should we deal with this situation?
1. After the game, you need to check whether there is a foreign body attached to the body, or there are other adverse reactions on the skin.
2. If you are bitten, you can apply ether or chloroform to the head of the insect, or light a mosquito coil on the side to loosen it; you can also use vaseline to thickly apply to the head of the insect to suffocate it, and then gently pull it out with forceps. If the mouthpiece remains in the skin, it needs to be removed surgically.
3. Timely disinfection and closed treatment afterwards, antihistamines or glucocorticoids are given for symptoms of systemic poisoning, and paralysis or fever and headache need to be rescued in time.
Caterpillars
Caterpillar is what we often call the caterpillar, is the larvae of the poisonous moth, it will not bite like ticks, but the ability to hurt the poisonous hair itself cannot be underestimated, it can make people dermatitis through contact, and often accompanied by itching or burning, and then more serious will cause arthritis, cysts, headaches and other general discomfort reactions.
What should I do if I accidentally come into contact with caterpillars or poisonous hairs?
1. Usually, it is observed with a magnifying glass/microscope, and after confirmation, the skin is repeatedly pasted with tape at the contact area to remove the poisonous hair.
2. After removal, calamine lotion can be used externally, antihistamines can be taken orally for itching, and those with systemic symptoms need to be treated systematically.
Three Poisonous cryptoptera
Poisonous cryptopterynhoppers do not bite like ticks, nor do they have their own poisonous hair like caterpillars, but they are representative insects in "can't shoot".
There is a strong acidic sap in the body of cryptoptera, and although most insects do not release venom when crawling on the skin, after being crushed (or accidentally crushing it while sleeping) can cause damage to the skin.
The degree of damage to the skin is related to the type of insect and the body's reaction, and there may be punctate or cord-like erythema, or a large area of erosion, superficial skin necrosis, and may also cause symptoms of general malaise.
So what to do?
1. The poisonous cryptoptera is diurnal and has phototropism, so in addition to closing the screens and mosquito nets at night, remember to turn off the lights.
2. If it falls on you, blow it away gently.
3. If you accidentally shoot it, you should wash it with soapy water as soon as possible, and then use calamine lotion or corticosteroid cream topically. If redness or erosion is obvious, apply 1% to 2% alum solution or 1:5000 potassium permanganate solution cold compress, and apply zinc oxide oil after the exudate is reduced.
Itching is obviously possible to take oral antihistamines, in severe cases it is recommended to seek medical attention in time.
After encountering these bugs, they all have one thing in common, that is, do not scratch after they occur to avoid aggravating the disease.
Some bugs can't afford to provoke, endure the calm of the wind and waves, take a step back from the sea and the sky, if you see it falling on you, don't worry about the poison hand, because you may be hurt more, it is better not to shoot.
