In summer, screen windows are used at home to ventilate and prevent insects. The so-called insect protection mainly prevents mosquitoes. It seems that few people use mosquito nets anymore, but people of our age must have the impression of mosquito nets.
The mosquito net is hung on the top of the bed, and the bed is covered in groups. After getting in, turn around and press the surroundings under the mattress, and then check inside the tent to see if there are any mosquitoes that slipped through the net and fly in. I got blood on one hand, and I don’t know whose blood it was, so there was a small pool of blood on the white mosquito net.
After the inspection, there must be no mosquitoes left, so you can lie down and sleep, but you may not be able to sleep soundly, because as long as your hands and feet are attached to the mosquito net, the mosquitoes outside the net will bite you and pass through the mosquito net. Insert the tube through the porous hole and still suck blood. At that time, there was no air-conditioning, and in the summer, the windows of every house were open, like attracting mosquitoes to a party.
Mosquito extermination seems to be something that humans have been doing since ancient times. Even when they did not know that mosquitoes could infect malaria and encephalitis, people tried their best to prevent and kill mosquitoes, because it was really abominable. So whenever there is news about killing mosquitoes, it is particularly attractive. Just like a piece I saw two days ago, foreign scientists discovered that male mosquitoes can only find a mating partner after hearing the vibrating sound of female mosquito wings. If it fails, the female mosquito will not be able to mate for a lifetime.
So scientists invented a potion that can interfere with the hearing of male mosquitoes. It can deafen it, but it can’t touch female mosquitoes. This is very exciting news, especially for people who are particularly attracted to mosquitoes, it is more like seeing the great news of getting rid of the sea of suffering.
Not all things invented by scientists are good, but this one is really good.
