Buy insect repellent - "Executioner"
The common housefly is rightfully considered one of the most "ordinary", if I may say so, types of insects, in the prevalence with which in the human habitat, well, perhaps a mosquito can compete.

Actually, we will try to find out in this review about what a house fly is, why it appears in the house, how long the fly lives and how such a neighbor in the living space can harm.

The main purpose of insects
The benefit of flies lies in the peculiarities of their nutrition, vital activity, and habitat. Spreads of infection, bacteria, they become unwillingly, in contact with the environment, which is teeming with pathogens.
A semi-liquid medium is required for the development of larvae, as well as a large amount of protein. The female lays eggs on rotting, spoiled food, vegetables, fruits, decaying parts of plants, as well as meat, corpses, deep wounds on the body of animals, humans, left without due attention. A large number of larvae of different types of flies develop in feces, garbage, cesspools, drains, drains, sewers.
They feed on liquid food - juices. Favorite food - honey, jam, syrup, ripe fruits, lemonade. In the absence of these products, they switch to more solid foods. Initially, it is treated with a special secret - saliva, then sucked in. But most of all, meat flies, which develop in the meat of animals, fish, and rotting wounds of a person, bring benefits and harm.
On a note!
Flies benefit from the ability of their larvae to decompose tissue. The larvae are nature's orderlies. If it were not for these creatures, there would be decaying corpses of animals, birds, rotting plants, fruits, vegetables everywhere. Females of flies are attracted by smells of decay, sweat, bacteria.
Ways to fight
Since the pupae of miner flies hibernate in the soil, they dig deeply to combat them.
the ground, due to which the pupae go deeper into the ground and die.
Since beet miner flies are able to feed on weeds of nightshade and haze weeds, it is advisable to destroy nearby weeds of these plant species. To combat miner flies, you can use parasitic entomophages - special insects that feed on these types of flies - but their use is effective only in greenhouses.
Various insecticides are also used. Pre-sowing seed treatment can be used. For example, in the fight against the beet miner fly, the treatment of beet seeds with the "Tabu" preparation is effective. It makes sense to use preparations of the nicotinoid group only with soil application.
"Verimek", which has the ability to penetrate deep into the leaf, copes with both adult flies and larvae.
What are flies for?
Flies in nature
During the First World War, doctors noticed one feature - the larvae ate rotting tissue in the wounds of patients, prevented the reproduction of pathogenic microflora.The larvae secrete a special secret, which is the strongest antibiotic. This allows maggots to exist freely in an aggressive environment, and this feature is used by doctors to treat severe wounds that are not amenable to antibiotic action. Maggots are specially grown under sterile conditions.
The complex fly eye became the basis for the development of the modern camera. The unique camera takes more than 1 thousand frames at a time, after pressing the shooting button. Body structure and flying ability formed the basis for the creation of many structures in aviation. Research continues, it is not fully understood how the fly sits upside down on the ceiling, takes off without preliminary acceleration, hangs in the air, turns off one or the other wing during flight. Flies benefit from their presence as they provide numerous aspects to explore. The flight of a fly and the reaction of an insect has been compared to a flying saucer - a UFO.
On a note!
Flies are needed in nature as plant pollinators. Many species feed on juices, nectar, cling to pollen on their paws, and carry with them. Often unique plants that smell of carrion and rotting products are pollinated. An unpleasant smell scares away bees, wasps, hornets, for flies it is an attractive aroma.

Basically, it lives in semi-desert, desert and steppe regions.
Mosquitoes and flies in the ecosystem
Fishermen use maggots, mosquito larvae for catching large fish. They buy such a bait specially or breed it themselves. Unusual food is purchased by the owners of aquariums and terrariums. Maggots are eaten by birds, lizards, frogs, chameleons, spiders.
We need flies in nature, the ecological system to maintain the food chain. Adults and their larvae become a delicacy for amphibians, birds, other insects, and spiders. The ground beetle eats flies. For fun, cats and dogs hunt for buzzing insects.
Interesting!
Maggots are bred in special containers, providing favorable living conditions. Meat of animals, poultry, and much less often fish are chosen as a habitat, food products. At a certain stage of development - after 2 molts, they are placed in a cold environment to prevent pupation.
How do they look
Fly eggs are white, very small, oblong. When zoomed in, they look like grains of rice. Inside there is a nutritious yolk, due to which the fruit develops.
Immediately after emerging from the eggs laid by the fly (at the initial stage of development), the maggot body length is approximately 2 mm.After 1 molt - 4-5 mm, after 2 - 8-9 mm, before pupation - 10-13 mm. Weighs about 22-27g.
Adult fly larvae are small yellowish, gray or cream-colored worms, shiny, with a barely pronounced brown head, on which there is a mouth opening with retractable hooks. The back of the body is slightly rounded.
The maggot has no normal (jointed) legs. Movement (locomotion) is provided by false legs (outgrowths with cavities), creeping rollers (thickenings on the sides of the body), and contractions of the whole body.
The prepupa is the same color as the larva. As it hardens, the puparium darkens, eventually becoming brown. The pupa looks like a small barrel with transverse circular notches.
Lifestyle - good and bad sides
The most important purpose of flies is tissue decomposition, which is both beneficial and harmful. Living in an unfavorable environment, and then, sitting on food, insects spread pathogens. The most dangerous disease is leprosy, the most common is intestinal infection.
The larvae are able to live for some time under the skin, in the intestines, internal organs, and eyes. The penetration of maggots into the brain becomes the cause of death. Therefore, you need to take all possible measures to prevent flies from entering the house, carefully process vegetables and fruits brought from the street.
Why is everyone so scared by the Spider
The symbol of evil and the devil, weaving a web for the souls of sinners. A symbol of avarice and bloodsucking. Ancient symbol of the nerve knot in the human body.
In mythopoetic traditions, the image of a spider is associated with creative activity, professional and craft skills, industriousness, auspicious omens (cf. in this regard, the prohibition to kill a spider), wisdom, as well as cold cruelty (cf. sucking blood, diabolism as the realization of the symbolic meanings of a spider in Christianity), greed, wickedness, witchcraft.
The use of a spider in magical medicine is known both to protect a person from diseases, and to send them to him (in black magic).
There are stories about how a spider saved the infant Christ from the cruelty of Herod.
In a number of folklore texts, the web serves as a guiding and (or) saving thread, connecting the Heaven and Earth, or some points of the horizontal plane.
The ability to move in all directions explains the motive of the cunning of the spider, which is constantly noted in fairy tales.
It is sometimes combined with motives of greed and cruelty (cf. tales about a spider and flies, mosquitoes and other small insects; Russian fairy tale about misgir: “Confused that misgir is in the snare”).
The Great Mother in the terrible guise of the weaver of fate is sometimes depicted as a spider.
All moon goddesses are spinners and weavers of fate, and the cosmic spider, the great spider, or the great spinner, is the creator who spins the thread of life from his own substance, attaches to himself through the umbilical cord all people and weaves them into the web of the patterns of the world.
The spider in the center of the web, as an ancient symbol, personifies the center of the world, the sun surrounded by rays emanating from it in all directions; the moon, personifying the cycles of life and death, spinning the web of time.
In Christianity, it is the devil who lures sinners; the miser who drinks the blood of the poor. The web of life, fate and time is woven by divine powers.
