Before the reform and opening up, there was a shortage of commodities, and there was no shortage of lice, fleas and bed bugs. They are companions to people, inseparable and annoying. Today's young people have little impression of them, but people born in the fifties and sixties and before, when they mention these things, they all hate them.
louse:
The body of the lice is three or four millimeters long and grayish-white. From such common sayings as "there are more lice and don't bite people", "itching, not worse than the lice", and "take impure lice, catch impure thieves", we can see that lice and people have a close relationship and a long history.
Most of the lice live in the crevices of people's intimate clothes, which are safe, comfortable, and have no food worries; food is on the mouth, feel hungry, lie down on people to eat a full meal, and when the stomach is round, they turn over and go to sleep.
Sometimes, there are too many lice on the body, resulting in crowding, and there are lice crawling into the hair to camp, and it is very convenient to eat, live, and even have children.
With lice on it, let it drink some blood and pour it on the back; the important thing is to make it itchy and uncomfortable. So, when people are idle, there is a lice-catching activity. Lu Xun has a description of Wang Leper Hu and Ah Q catching lice in "The True Biography of Ah Q", and Ah Q feels that he has caught more lice than Wang Lily Hu, and the bite in his mouth is not loud enough, and he is deeply disappointed, so the two people also fight hard.
Once lice have settled on people, it is difficult to catch them clean. The lice are hidden in the cracks of the clothes, very hidden, and at the same time they also lay eggs on the clothes, and the warm human body is like an incubator, and in a few days, the little lice hatch, and their ranks continue to grow.
The lice hidden in the hair, if slowly combed with grates, can be cleared out of the jungle, snapped and fell to the table, and then eliminated one by one; but the eggs they lay, stuck firmly in the hair, shaved their heads, is a complete solution to the problem. There is a saying, "The lice on the bald man's head are obvious." "However, if the lice are really exposed to broad daylight, they will be terrified and flee."
If you want to cut the lice on your clothes and remove the roots, you can only cook them in boiling water, but this is only a short-term benefit, because even if you cook all your underwear, there are scattered soldiers on the cotton jacket, there are still large troops hidden in your hair, on the quilt, and there are countless lice on other family members, and before long, they will migrate and settle down again.
Lice and people in close contact, scratch impure, hot endlessly, if you want to use insecticides and the like to eliminate lice, then a bit of a rat taboo, a little common sense people, do not dare to rush to do. I have a colleague who lived in my grandfather's house in the country when I was a child. One day, my aunt saw a lice crawling from the little guy's neck to his head, and quickly squeezed it with her hand and put it in her mouth to bite it. Then he took off his cotton jacket and looked at it, only to see that it was full of lice, and there was nowhere to catch it. The cotton jacket could not be boiled in water, so the aunt smeared pesticides on the seams of the cotton jacket, trying to kill the lice. After the little guy put on the cotton jacket, he sat on the hot kang head to play, and after a while, he was a little sleepy, sitting unsteadily, and then spitting out white foam and speaking incoherently. Panicked, the family rushed to the hospital, and the child's life was large, and he was rescued.
flea:
Fleas are smaller and browner than lice. Fleas, as the name suggests, are good at jumping. The fleas are less than two millimeters tall, and when they jump hard, they are fifty or sixty centimeters long, which is more than three hundred times their height. If people can jump according to this proportion, a guy can jump more than five hundred meters, fall down, and fall to pieces. But the fleas are fine, falling from a high place, flipping over a few heels at most, standing firm and appearing unscathed. I think the reason for this is probably because the flea's body is particularly hard, so it is very resistant to falling.
The fleas are very flexible, and when you find it, you quietly extend your fingers and try to hold it, it has already jumped without a trace. Sometimes you happen to hold it down, but it struggles under your fingers without showing weakness; you press hard for half a day, feeling that it has been crushed to death, trying to move your finger and pinch it, but it takes the opportunity to escape.
Fleas do not have the same intimate contact with people as lice, they make earth kang their home. At night, people are asleep, and with their own very stress-resistant characteristics, they drill between the human body and the kang mat without scruples, making people feel that there are countless small bugs squirming under them, which are extremely itchy, and the fleas are feasting very happily below.
Fleas are not as close to the body as lice and can be killed with insecticides; you can also put a basin of water in front of the kang, and when the fleas jump up, if they are unlucky, they will fall into the water.
bedbug:
Bed bugs, as the name suggests, have a foul smell on their bodies. Bed bugs that come out to bite people, vary in size, grandfathers and grandchildren, those heavyweights are full of blood, like a flattened red bean.
Bed bugs prefer to live in the crevices of bed boards or other wooden furniture, and some climb to the ceiling to find a hidden place to settle down. Bed bugs generally do not live under the kang mat, because its body is soft, there is no bone support, and the person on the kang will kill them as soon as they turn over.
Bed bugs have large targets, are slow to move, and are extremely easy to catch. Therefore, bed bugs generally come out day and night, take advantage of the fact that people are asleep, rush to eat a meal, and then quickly evacuate.
Bed bugs are very cunning, some people found that the bed bugs living on the ceiling, in the middle of the night, when they want to come down to forage, in order to be convenient, labor-saving, and fast, they jumped directly from the nest where they lived, fell on the sleeping people, waited until they were full, and then slowly climbed back.
Bed bugs eat a lot of food, and are very greedy, and every time they suck blood, they almost burst their stomachs before they stop. In addition, when bed bugs bite people, unlike lice and fleas, they are only itchy; when bitten by bed bugs, they are itchy and painful, and they can't help but scratch a few times, and the big bumps of corn kernels bulge up.
The vitality of bed bugs is very tenacious, they do not eat for a year or two, they are hungry and only have one skin left, they still can't die, and once they have eaten enough, they will be full of vitality. In addition, bed bugs hide in the cracks of furniture, and it is difficult to catch them. The best way to kill bed bugs is to bring furniture into the yard and boil it with boiling water.
Lice, fleas, bed bugs are guys who have been with people and have suffered a lot. With the improvement of people's living environment, the improvement of living standards, and the change of health habits, it has gradually disappeared. It seems that the progress of material civilization is too important for people to live a comfortable, comfortable and dignified life.
