Mosquitoes, how do flies come from, how do flies come from home?

Mosquitoes rely on their sense of smell to identify the location of food at long distances, and their super-sensitive sense of smell can always find a way to get closer to people (this is something that many animals have). Once close to the person, it uses thermal infrared to perceive the proximity of the blood vessels in the human epidermis**, and chooses the place of the lower mouth, (in its eyes, it is like the color of the animal seen by the heat sensor). Close to the crimson area, use the tip of the blade mouthpart (scalpel principle) to make an incision**, secrete your own saliva to reduce the pain of the other person (the principle of anesthesiology), and use a pump mouthpiece to suck in blood (syringe principle).

Mosquitoes have been on Earth for a lot longer than humans, hehe.

As a life species on the earth, flies naturally have the meaning and value of their existence, as early as more than 2 million years ago, flies began to breed on this planet, and there are 60,000 species of its family members. After years of evolution, the fly has a particularly remarkable eye, which is made up of more than 2,000 compound eyes, giving it a wide field of vision. Exceptionally keen sense of smell, with the ability to fly long flight stunts and fly rock walls.

In fact, the members of the fly family are also diverse, most praise the industriousness of bees, but few people know that some flies are also hard gardeners in nature, tirelessly pollinating the plant media. At the same time, flies are also a good meal for some animals in nature. Of course, our most common, and the most studied by scientists, is houseflies.

Every year, when the weather gets colder, the few flies that occasionally haunt the house are suddenly gone, not only the heart is refreshed, but I am grateful to the Creator for giving the flies the nature to be afraid of the cold. Before I could regain my taste from the excitement, one or two elusive flies and warm heating floated in, not surprised, not surprised!

The door to the house is closed, how the hell do the flies come from?

Maybe on a pleasant afternoon, it wanders at the door or window, and it quietly comes to the house as a guest with a small slit. Sometimes it dances happily with you, and sometimes you feel that it is gone, or that it is unfortunate. But I'm telling you that if you want it to go through a few doors, a lot of windows, and find out that one day the door can be opened once in a while, and it will have to be a Conan fly.

In addition, you don't have to worry that it will be unlucky at home, the lifespan of flies varies according to the temperature, below 10 degrees, as long as it is not frozen to death, it can live for more than 3 months.

So the little fly that came from the front, it has always been with you in your home, and it has never left. It may also find places with water to reproduce, such as in a vase with water, in the bottom of a pot, or even in moist pot soil.

So if you have a fly at home and you don't finish it yourself, it's normal for the fly to appear again within 2-3 months.

It may also be related to the outside environment, there may be a lot of piles of household garbage near your home, and there will be a lot of flies.

Or the windows and doors of the home are not tightly closed, or places such as chimneys, sewers, toilet ventilation ducts, air conditioning outlets, balcony overflows, etc., take a thorough inspection.

In addition, every time you enter and exit the door and open and close the window, pat and shake it in advance to scare away the mosquitoes and flies guarding the doors and windows, otherwise you will also take advantage of the situation.

4. The simplest thing at home is a fly swatter. When there are children at home, it is best to use less pesticides and buy green and harmless electric mosquito coils to use. Prevention is more important.

In my house, flies fly in your ears at night when the lights are turned off, what should I do?

When the door is opened or the window is opened, it comes from outside.

1. Types and habits of flies.

Common flies in people's lives include houseflies, toilet flies, mercerized green flies, big-headed goldflies, black-tailed hemp flies, etc. The life of a fly can be divided into four stages, that is, from the adult fly mating and laying eggs, through the egg-> larva (maggot)-pupa-> adult fly process, this process only takes about 10 days, and can be shortened when the temperature is high. Flies can lay eggs for life when mating, a female fly can lay eggs 5-6 times in a lifetime, 100-150 eggs each time, and after ten days, these more than 100 eggs will become adult flies, so a fly can reproduce thousands of flies in a lifetime.

Spring is the peak of the first generation of adult flies, and the elimination of one fly in the spring is equivalent to the elimination of tens of thousands of flies in the summer.

2. The harm of flies.

Flies feed on garbage heaps, toilets, rotting animal carcasses, pus, blood, sputum and vomit. It carries tens of thousands of bacteria, viruses and parasite eggs on its body and abdomen. Flies have the habit of eating, spitting and pulling, and he flies down to **, ** food and utensils will be contaminated by bacteria, viruses, and insect eggs, and when people eat contaminated food or use contaminated utensils, intestinal infectious diseases or parasitic diseases can occur.

3. Sanitize and control measures.

1) Focusing on environmental management, eliminating the breeding ground of flies, strengthening the management of garbage and feces, and making garbage sludge clean to Nissan Nissan and carrying out harmless treatment. Public toilets should be managed by special personnel, cleaned and flushed regularly, so that there are no maggots and no flies.

2) Use a combination of swatting and medicine to eliminate indoor and outdoor flies, reduce their density, and spray the places where flies are active with malathion, bethion, trichlorfon, and inulinoids, and poison flies. At the same time, it is necessary to vigorously advocate the eradication of the first generation of adult flies in spring.

3) Cooked foods such as meals and pastries, as well as washed utensils such as dishes and chopsticks, should be stored in a gauze cabinet or covered with a gauze cover to prevent contamination by flies.

1 Anterior and posterior pinching. Scientists' findings have shown that the central nervous system of flies can only take care of a certain aspect of the field of vision in the process of transmitting information each time.

When there is an external attack or collision on this side, most flies can deftly dodge. However, when the fly is approached at the same distance from the side at 180 degrees in both directions and attacks, the central nervous system of the fly is unable to quickly judge and react.

2 Tobacco fly extermination. Peel off the cigarettes, take the shredded tobacco and burn it in the pot, grind it into fine powder, add a small amount of sugar and minced fish offal, mix it on the paper, and put it in a place where flies often hang out, and flies can lose their ability to fly after eating.

1. Flies are developed from fly eggs. The life cycle of a fly is calculated in days, its egg stage is about 1 day, the larval stage is 3 to 6 days, the pupal stage is 3 to 7 days, and it only takes 7 to 14 days from egg to adult.

2. About 1 day after the fly lays eggs, it can hatch into fly maggots, and the food of fly maggots includes livestock feces, garbage and some decaying materials. Maggots are very active, constantly turning around, and when they are mature, they crawl to the surrounding drier environments such as loose soil, sawdust, etc. to pupate, and if the surface of the food is dry, they can also pupate on the surface of the food. Then crawl out of the chrysalis and become a fly.

1. All living things have the value of their existence. If saprophytic insects such as flies are all extinct, nature will not be able to deal with animal and plant carcasses.

2. Flies and mosquitoes can balance the biological chain. However, when a species becomes extinct, other species at the same level as the biologic chain will take on the task of extincting the species. So it's normal to exterminate one or two species, but if you want to artificially exterminate a species, it will have unimaginable consequences.

3. The extinction of species in nature is the survival of the fittest, and the ecosystem is not ready to do well when species are extinct by man, so it will cause local chaos, and if there are many extinct species, it will be global chaos.
