Green fly: description, photo. How to get rid of green flies?

The green fly belongs to a large family of blow flies - about 900 species, grouped into 23 genera. Other names: carrion, calliphorid, sarcophagus, meat. Distributed throughout Russia, lives in the warm season. It brings tangible benefits to nature, but harms humans and animals. The green fly is one of the largest representatives of the genus and has an attractive color.

Description of appearance

The body structure of the green carrion fly is similar to that of a regular fly, only the first one is slightly larger. The length of its body reaches 1.5 cm. The eyes look like large red spots that occupy a large area of ​​​​the head. The back and abdomen have an emerald shine with golden tints. In the photo of a green fly you can clearly see its bright color.

On a note!

The scavenger moves much slower than its relatives. It is easier to catch or kill it mechanically. Another difference between an insect and an ordinary fly is a significant hum during the flight, so you can immediately understand that a green carrion fly has flown into the house.

A brief excursion into biology

Carrion flies are insects with a green body (with a metallic or golden tint). The size of carrions is up to 1 cm. The antennae are strewn with bristles. They are found everywhere, both on the street and in houses. Green flies carry microbes and parasite eggs.

There are more than 1,500 species comprising various carrion or blowflies. All of them have a brightly colored body, with a metallic tint, green or blue. Green blowflies belong to the genus Lucilia.

For nutrition, they use liquefied material of rotting organic matter (pus, decomposing proteins), which are liquefied under the influence of enzymes secreted by the maggots themselves.

What to do if you are bitten

At the site of a fly bite, severe irritation often occurs with swelling of the soft tissues. If you are bitten by a fly, immediately wash the bite site with cold water to reduce skin irritation. If you have antihistamines in the house, they can be used to relieve an allergic reaction. If there is pain and itching at the site of the bite, you can apply ice, a lotion with soda and other means that can reduce the discomfort. Insect bite repellents are also suitable.

The wound must be disinfected. If the allergic reaction at the site of the bite does not go away, you should consult a doctor.

Biology

Adults of calliphorid flies are, as a rule, brightly colored green or blue with a metallic tint; less often dark gray with brown.

Typically carrion flies that develop on corpses are representatives of the main genera of the family - green carrion flies (Lucilia) and blue carrion flies (Cynomya, Calliphora). Their females require a significant amount of protein (up to 800 mcg) to develop eggs. Having found carrion (sometimes the fly has to fly up to 20 km to do this), females lay white eggs measuring 1.5x0.4 mm - 150-200 eggs at a time. In total, a female can lay up to 2000 eggs in her life. For the larvae to hatch, it takes from 12 hours to 1-2 days (depending on the ambient temperature). Digestion in larvae is extraintestinal - they absorb food liquefied by their proteolytic enzymes.

There are two types of carrion fly larvae: smooth and “hairy”. The first are exclusively scavengers; the latter are predominantly active predators, feeding on smooth larvae, and appear on carrion later than the former.

The larvae go through three moults and then pupate. At room temperature (approx. 30 °C), the black carrion fly Phormia regina transforms from egg to pupa in 6-11 days. The larva burrows into the ground and, if the weather is favorable, emerges from the puparium after 14 days as an adult insect. Because the life cycle of carrion flies is well understood, they are used in forensic science to determine the time of death.

In addition to carrion, many species of carrion flies develop on the excrement of humans and animals. It is not uncommon for the same species to develop both on carrion and in feces. Feeding on decaying meat has created the preconditions for a number of species of carrion flies to transition to parasitism on living beings: pollen flies (Pollenia), for example, retain the ability to develop in meat, but their larvae are often found in the body of earthworms, which they gradually eat. There are species that parasitize snails and live in termite mounds and anthills. Parasitic carrion flies can develop in necrotic tissues and cause myiases in animals and humans. Thus, the damage caused to the Australian sheep industry by the fly Lucilia cuprina, which parasitizes sheep, is estimated at 170 million US dollars annually.

Adult carrion flies sometimes become pollinators of flowers, to which they are attracted by a strong smell, similar to the smell of rotting meat (like pawpaw).

Life cycle

The Drosophila fly lays eggs in a moist substrate rich in organic matter. This does not have to be rotting fruit, although all other things being equal, the female will prefer such a carbohydrate-rich environment. Development time from egg to adult is 10 days at a temperature of 25°C. Already at 18°C, development slows down by 2 times.

Under favorable conditions, the Drosophila larva emerges from the egg one day after the female lays eggs. The length of the newly-minted individual is 3.5 cm. The offspring grows for only 5 days and during this time manages to molt 2 times: 24 hours after hatching and 48 hours later. Eggs and larvae are well adapted to exist in a semi-liquid environment, since the fly lays eggs on half-rotten fruits.

At first, the larvae swim on the surface, and before pupation they go deeper. During the active period of life, they feed on fruit-decomposing bacteria and substances from the fruit itself. On the fifth day, the transformation into a pupa begins and continues for 5 days.

A young female, emerging from the pupa, can begin mating no earlier than 12 hours after “birth.” The female fruit fly mates once and stores the male's sperm for later use.

Life cycle of a fly

The length of time an adult Drosophila lives is usually 1-2 months, depending on environmental conditions. At high air temperatures, the lifespan of an individual insect is reduced. During her life, the female lays 400 eggs measuring 0.5 mm. With a short life cycle, the turnover of generations increases and the number of flies increases rapidly in the hot season.

External body structure

The general body plan of the fly is the same as that of other winged pests. The head contains the mouthparts, organs of vision and antennae. On the chest are transparent wings and three pairs of legs. The abdomen hides the digestive and reproductive systems.

Important: insects have pronounced sexual dimorphism, that is, females are visually different from males.

Head

The main feature of the fly is its compound eyes. They allow you to view the space 360 ​​degrees. There are more than 3,000 small facets in each eye. Each eye transmits a separate image to the brain, where the overall picture is formed.

The fly obtains food for itself with the help of its proboscis. It can be of two types:

1. Sucking.
2. Licking.

In an insect that feeds on blood, the mouthparts are additionally equipped with sharp plates that help pierce the skin of the prey.

With the help of antennae placed on the head, the pest orients itself in space. The front sight determines the direction of movement and also picks up odors.

Important: males have large eyes, thanks to which they react faster.

Chest and wings

The fly's chest is divided into three segments. The most developed is average. This is due to the fact that the insect flies a lot. There are 6 paws on the chest, with the help of which the pest can crawl not only on a horizontal surface, but also on a vertical one. Each paw is equipped with suction claws.

Important: with the help of the fly's legs it determines the taste of food.

Few people know, but the pest has 2 pairs of wings. Some are large, others are small - halteres. They are the ones that make the annoying sound.

Abdomen

The third part of the body is the abdomen. It has a cylindrical shape and consists of 10 segments. The abdomen contains organs responsible for respiratory function, nutrition and reproduction.

Flies that live in apartments weigh about 13 mg. The abdomen can accommodate 3 mg of food, that is, body weight after “breakfast” increases to 16 mg.

Appearance Features

Externally, the green carrion fly differs from the house fly in its larger body size, bright green color with iridescence, and a metallic tint. The external and internal structure of the body is ideally suited to her lifestyle.

• Size from 8 mm to 2 cm.
• The entire body is densely covered with short villi.
• There are small antennae on the head.
• The head is well defined with large red and brown eyes.
• A pair of transparent wings with well-marked membranes. Located along the body, slightly splayed to the sides.
• The second pair of wings are underdeveloped and are called halteres. They perform an important function - they maintain balance in the air, allow you to hover in one place, and also create sound during flight.
• 6 pairs of paws. A special fatty substance collects at the tips, which allows flies to easily stay on any surface in a vertical or horizontal position. This explains how the insect sits calmly, crawls on the ceiling and on the glass of the windows.

A photo of a green fly is shown below. The insect lives in the wild and enters the house by accident or under certain circumstances.

Interesting!

To search for food, a fly can fly up to 20 km, and can fly almost 3 km without stopping. Orients with a sensitive sense of smell and excellent vision.

Habitat

Emerald lucilia is common in many countries of the world with warm summer climates. Its peak activity occurs during the hottest time of the year. It is in the heat that decay processes most strongly emit an odor, which is a bait for insects. In addition to carrion, green-bellied flies are also attracted to other sources of unpleasant stench:

• feces;
• rotting fruits and berries;
• plants with a rotting smell;
• food waste landfills;
• fresh and salted fish;
• meat.

Large concentrations of carrion insects can be seen near slaughterhouses, meat shops, and livestock farms. They are also found in large numbers near fish processing plants, where fish are cleaned and cut.

On a note!

An apartment or house can attract meat midges if there is rotting waste or a dead animal somewhere nearby. Otherwise, the fly can only fly in by accident and will try to fly out at the first opportunity.

Nutrition

For food, flies and larvae use the meat of decomposing corpses, rotting fruits and vegetables, meat products, as well as other organic substances that are in the process of decomposition.

Among other things, the blowfly larva can eat the eggs of beetles, other flies, grasshoppers and caterpillars. They are characterized by extraintestinal digestion of food.

Habitat

When the fly is not looking for food or a place to lay larvae, it can be found on various flowers, near cesspools and latrines.

As for the larvae, they can be found not only on rotting fruits and decomposing corpses, but also on feces, manure, in a polluted body of water, and even in an open wound of an animal.

Medical significance

Flies, attacking a person in order to feed on blood or secretions from wounds, mucous membranes and sweat glands, greatly annoy both adults and children.

From an epidemiological point of view, the role of flies is especially important in the spread of intestinal and eye infections. By coming into contact with the feces of sick people, flies receive pathogens of dysentery, typhoid fever, cholera, as well as protozoan cysts and helminth eggs. The causative agents of these diseases remain on the body of insects for several days. They do not lose virulence in the intestines of flies. Having passed through the digestive system in a virulent state, the pathogens, together with belching and feces of flies, end up on human food and household items. Flies may be involved in the transmission of foodborne diseases. They acquire the causative agents of these diseases by feeding on animal corpses and meat stored in violation of sanitary rules.

Infectious conjunctivitis and trachoma (eye diseases) are spread by flies by feeding on secretions from the eyes of a sick person and then coming into contact with the eyes of a healthy person.

The importance of flies in the transmission of the polio virus is undeniable. Their role in the spread of tuberculosis, as well as adenoviral infections, cannot be ruled out.

Blood-sucking flies can be mechanical carriers of tularemia, anthrax, and staphylococcal infections. The larvae of some fly species cause tissue or cavitary myiases.

Types of blow flies

The most common types of blowflies include the following:

• green;
• gray;
• blue.

Green fly

The green blowfly has a body size of 5...10 mm in length, which has a greenish color that shimmers with a metallic tint. The insect's abdomen has a somewhat lightish tint.

Green fly

The fly's legs are black, the tentacles are slightly yellowish, and the wings are transparent. This type of fly is very thermophilic and is mainly found in hot summers.

gray fly

Gray blowflies have a fairly large body, the length of which can range from 10 to 15 mm. Attached to the body is a white and yellow head, divided by a black stripe and having red eyes.

gray fly

The insect's chest is covered with light stripes, which are located longitudinally. The legs of the fly are distinguished by thick, short hair.

blue fly

The blue blowfly is one of the largest - its body length can be 10...16 mm, and its color is blue with a lightish tint. Attached to the body is a head, colored yellowish-red with a golden sheen, and having short antennae on the sides.

gray fly

The insect's chest is painted black with an iridescent bluish tint, and black stripes are visible on the back.

Treatment

Many diseases carried by blowflies have specific treatments. Special vaccines have been developed for many. And yet, the main disease transmitted by blowflies is myiasis, the treatment of which we will describe in detail.

Location of the larvae

Since myiasis can be both internal and external, their treatment is different. If the skin is damaged, it is necessary to wait for the larva to mature, after which it moves outward and can be easily removed from the wound using tweezers. To speed up the progress of the larva, you can use various oils: vegetable, camphor, vaseline or those that you have at home. The oils prevent the access of oxygen, thereby causing the larva to move outward. After the larva has been removed, the wound must be treated with an antiseptic and a sterile compress with a disinfectant applied; in case of significant damage, external or systemic antibiotics can be prescribed. And in no case should you try to remove the larva before it approaches the exit, this can lead to its rupture and suppuration of the wound. If internal organs or intestines are damaged, antiparasitic drugs are used; if it gets into the stomach, it is washed out.

Reproduction

The green fly lays about 150 eggs at a time, but in a day their number can reach five hundred. To protect the offspring from bright sunlight, to which they are very sensitive, the female looks for deep folds or holes in the flesh of the carrion, and, if possible, climbs under the corpse to lay eggs.

The insect is not at all concerned about other scavengers, such as ants, which carry freshly laid fly eggs. Her offspring are so numerous that such petty theft will not affect the general population.

Larvae

The larvae of green flies hatch from eggs a day after laying. They are small in size, whitish with a small black head, which has a mouth opening and two sharp hook-shaped protrusions, which the larva controls: it pulls forward, sticks into rotting flesh, and hides. Some sources suggest that these are modified jaws of the larva, with the help of which it captures microscopic pieces of flesh. Actually this is not true. The larva uses its hooks exclusively as a propulsion system. By thrusting them into the flesh, it tightens the body, so it is able to move.

Food resources

Adult L. sericata feeding on nectar
L. sericata larvae

feed exclusively on dead organic tissue; since the eggs are laid directly in carrion, they can feed on the corpse from which they hatch until they are ready to pupate. Adults are more varied in their diet, eating carrion and feces as well as pollen and nectar, meaning that they are important pollinators in their native range as well as important agents of decomposition. Pollen (which flies are able to digest, possibly with the help of bacteria in their digestive tract) can be used as an alternative source of protein, especially for pregnant females who require large amounts of protein and cannot reliably find carrion. It is noteworthy that pregnant women are especially attracted to sapromyophilic flowers that emit the smell of carrion, for example, a dead horse. Arum Lily. These flowers trick flies into pollinating them by imitating the scent of a corpse. However, flies also frequent myophilous flowers such as bull's-eye daisy and are attracted to the yellow color as well as the scent of the flowers.[8] This indicates that flies are attracted to flowers not only because they smell like carrion (in the case of the arum lily), but especially because of the pollen the flower produces (in the case of myophilous flowers).

How do larvae eat?

The larva cannot yet bite off pieces of solid food. How does she eat? During the research, an experiment was carried out: pieces of slightly dried meat were placed in two flasks, and green fly larvae were planted on one of them. After a few days, the piece of meat on which the larvae lived became so soft that it resembled more of a liquid pulp. At the same time, the piece of meat in the second flask did not change at all. That is, the larvae, secreting a special secretion from their mouths, liquefy solid food, turning it into a kind of broth, and then feed on this broth.

It turns out that they digest food before eating it. In addition, the hook-shaped projections on the head of the larva are also involved in the process of such digestion. As the larva digs its hooks into the flesh, it secretes digestive juices. It is absorbed into the meat in the places where the hooks were attached.

Having reached a certain age, the larva burrows into the ground, where it pupates. After a while, the cocoon lid bursts, and a young green fly appears from under the ground. After drying the wings a little in the sun, she rushes off in search of rotting flesh.

Stages of development

The green fly goes through the following stages in its development:

1. Egg – 8-25 hours.
2. Larva (maggot) – 10±3 days.
3. Pupa 3-4 days.
4. Adult – 45 days.

Carrion birds quickly find open wounds, dead birds, animals and lay eggs there on the very first day. But they can also be deposited in the damp soil of flowerpots, on rotten fruits and vegetables. The eggs look like white sticks 1 mm long. Development time depends on temperature and humidity.

After a day, small larvae (a little more than 1 mm) appear from them. They develop on a favorable basis - kitchen waste, feces, animal corpses. They have 1 mouth opening plus 2 respiratory openings. There is a black hook in the mouth with which they move.

The larvae constantly secrete juice through this hook, as if from a syringe, under pressure. Under the influence of fermented juice, the tissues quickly dissolve, forming a corpse broth on which the insect feeds. The larvae grow quickly, become thicker, larger, moving to pupation after 7-14 days, choosing warm, dry places.

The pupal stage (puparia) lasts 3 days. After hatching, the adults are ready to reproduce. Each female is capable of laying 100-150 pieces per day, repeating the process every 2 days. During its short life, 1 individual is capable of reproducing up to 700 eggs (6-8 clutches).

Some types of carrion flies can lay up to 2000 pieces in 1.5 months. During one warm period, several generations appear. In warm, indoor areas, insects can breed year-round. They overwinter in any phase except eggs.

Nutrition method

In our usual understanding of this word, burners do not bite. They scrape off the top layer of the epidermis with their proboscis, causing blood to appear. To prevent the blood from clotting, the burner releases poisonous saliva onto the scraping, the action of which leads to severe irritation.

Females need blood to complete the reproductive cycle. A hungry zhigalka will not be able to lay eggs. The desire to reproduce is the reason why this type of fly is especially biting in the fall.

Zhigalkas can overwinter at any stage of development, but already at temperatures below +8°C they hibernate. Before wintering, it is advisable for the female to have time to lay eggs. In the southern regions, at high air temperatures, this type of fly can breed all year round.

Harm and benefits of green flies

The main danger of blowflies is that they spread many diseases on their bodies, including cholera, dysentery, intestinal myiasis and typhoid fever. And given their fantastic reproduction speed, flight speed and penetration into all cracks, such a danger is very likely.

Flies also spoil a huge amount of food products, causing huge losses to food industry enterprises and livestock farming (they lay eggs in the nose, eyes, genitals, wounds, and transfer various pathogens and parasites from sick animals to healthy ones).

There are also benefits from carrion. By knowing the timing of blowfly development at all stages, forensic scientists can determine the time of death to the day, even if the body has been adversely affected. Insects were first used in search of killers back in the 13th century.

During the war, 100 years ago, maggots were used for field cleaning of wounds from dead flesh. Having learned that the juice of the larvae dissolves only areas that die and does not touch the living ones, they began to use them to remove necrotic layers.

First, they filled the wounds with maggots, and after a certain time they removed the cleaners, carefully cleaned the surface of the wound and obtained clean, living and sterile flesh. For medical purposes, special larvae were used, the cleanliness and sterility of which were monitored so as not to further infect the wounded.

Even now, options for using carcasses to treat tissue necrosis are periodically being developed, since dead tissue cannot be removed surgically so thinly, nanometers in size.

Breeding

For those who are not against breeding blow flies, and in particular their maggot larvae, this section of our story is intended. We will tell you how to make the simplest maggot from our favorite material for all kinds of crafts - an indispensable plastic bottle.

This is done as follows:

1. Cut the plastic bottle into two parts so that the upper part with the neck, being turned over and inserted into the lower half, does not reach the bottom by 4-5 centimeters.
2. Pour sawdust into the lower part of the “one and a half” or “kopeck piece” in a layer of two to three centimeters.
3. Place a piece of fresh or spoiled meat or a piece of fish in the upper part. By the way, you can also add a few small fish that you discarded after fishing.
4. Place the maggot in a shaded area.

When the meat begins to spoil, the flies will smell it and lay eggs there. The hatched larvae will feed on the substrate offered to them. Soon, a week after their eggs hatch, they will stop feeding in preparation for pupation, and will leak through the neck of the bottle straight into the sawdust.

Thanks to crawling in sawdust, maggots will be cleared of the smell of carrion, and you can take them with you fishing without hesitation. If you put an egg in a maggot, the larvae will be the largest.

Medicine

During the First World War, the unexpected property of carrion fly larvae settling in festering wounds was discovered. It turned out that the larvae of green carrion flies (Lucilia), blue carrion flies (Calliphora), etc., feeding on decaying tissues of wounds, not only remove these tissues and small fragments of bones, but also prevent the proliferation of pathogenic bacteria with their secretions. In addition, they secrete allantoin, a substance that promotes wound healing. However, flies taken from natural environments can introduce anaerobic microflora into wounds. Therefore, for the clinical treatment of difficult-to-heal wounds, laboratory-reared (sterile, that is, free from pathogens) larvae are used.

Functions in nature and harm to humans

For humans, all types of blow flies pose a great danger, namely epidemiological. After all, each of these insects is a potential carrier of various infectious diseases, including parasitic, bacterial and viral diseases. One of the most terrible diseases that a blowfly can carry is leprosy (leprosy), and the most common are various intestinal infections.

The fly gets infected due to the fact that it is constantly in contact with dirty places that are rich in feces, decaying biological tissues, rotting organic matter, etc. After this, the fly may end up on food, through which the infection can reach humans.

Blowfly eggs (larvae) can cause parasitic diseases in both humans and animals.

Blowfly eggs (larvae)

In addition to humans, blowflies are also very dangerous for animals. For example, in countries with warm and humid climates, there are many green blowflies, which cause the death of newly born lambs. Female flies can deposit their larvae in sheep's wool, as well as in open wounds, which will cause them to burrow under the skin of the animal, corroding its tissue.

Blowflies can also cause harm to fisheries or fish products. The female quite often deposits her larvae in fresh or lightly salted fish, which is why it loses its presentation and quickly deteriorates.

In addition to the negative aspects, the blowfly also has a positive property - it is nature’s orderly. Since flies feed on carrion, as a result of their vital activity they destroy rotting flesh and decomposing organic waste, preventing them from polluting the environment.

Continuing research

Due to its high forensic interest, extensive research has been carried out on its life cycle. However, current medical research is focused on the secretions produced by L. sericata

as an agent against MRSA and VRSA,[25] and the use of maggots for the treatment of maggots.
A new antimicrobial agent was isolated from L. sericata
secretions and patented under the name Seraticin.[26]

Efforts are being made to make healthcare workers more familiar with modern techniques.[27] Like many other ectoparasites, L. sericata

has a huge economic impact on farmers, so since the late 1980s, many studies and research projects have been carried out to help farmers reduce their impact. Research is also being conducted on less chemically intensive measures to control blowfly infestations, since chemical dip and pour is not only expensive and time consuming, but also toxic.

How to kill green flies

Don't wait for green flies to fill the entire area. You need to get rid of them as soon as you notice at least one adult. But before you get rid of green flies, you need to eliminate the cause of their appearance, that is, find rotting flesh that could attract these insects, and throw them as far as possible from your home.

As a rule, these measures are enough to get rid of unpleasant insects in the house. But it is worth remembering that flies live near livestock pens, and this risks the fact that insects can annoy animals, lay eggs in their ears, nose, accidental wounds, etc. In this case, regular treatment of livestock premises is necessary.

To properly combat the green fly, it is better to contact specialists from the sanitary and epidemiological station, who will quickly and competently eliminate the insects.

Pest control methods:

• fumigation – elimination through toxic aerosols, gels, smoke bombs, etc.;
• disinsection - treatment with chemicals of the main places where insects accumulate.

Life cycle

Cicadas are relatively long-lived insects. A group of periodical cicadas can have a total lifespan of up to 17 years. But the imago lives only for a few months and the main goal of the adult is to find a partner for reproduction. All periodical cicadas are North American species.

Life cycle of a cicada

In terms of the level of harm, periodic species do not reach the level of real locusts, but it is better not to plant young trees before their departure. Old plants easily tolerate the mass appearance of insects.

Song cicadas live shorter lives. But the underground period of their development is very poorly studied. Most likely, the time of underground development of the larvae is 1-2 years.

Fighting blowflies

To prevent the appearance of this pest in the house, you should know its habits, methods of entry, and carry out preventive measures along with control measures.

Ways of flies getting into human habitation

Green flies penetrate houses and apartments:

• through all sorts of cracks - green carrion birds fly very quickly, penetrate into the tiniest cracks;
• with vegetables, fruits, or wildflowers on which eggs are laid - when a suitable object for feeding appears, blowflies multiply at a fantastic rate.

These insects actively develop only when the weather is warm, but if the apartment is warm, then they feel great in winter. Even a single individual is dangerous, since it can lay eggs, and after that the attack on the house will begin in geometric progression.

Preventative measures against green flies

Eliminate or seal all kinds of nurseries: trash bins, manure pits, compost heaps or toilets.

Immediately destroy the carcasses of dead animals and birds.

Do not leave fresh meat or fish in a warm, open place; store food in airtight containers.

Treat insect locations.

Maintain cleanliness, quickly remove dirt, carry out wet cleaning, wipe off excess moisture, regularly ventilate the room, especially in the cool time of the day/year.

Cover windows and doors with mosquito nets.

Ways to combat carrions

Used against green flies:

• adhesive tapes - effective, safe for humans or animals, but do not guarantee complete destruction, last a long time, have a small radius of influence;
• insect repellent aerosols - effective, instant but short-term effect, cannot be used near food or where there are animals or people;
• powdered insecticides - act slowly, have a long-lasting effect, cannot be used where there are people, animals, or food;
• poisons for treating manure and garbage heaps - treatment weekly.

For larvae and pupae, larvicides are used:

• neoprene, baygon,
• creolin, naphthalizol,
• trolene, cyodrine,
• karbafos, metathion, others.

For adult insects - with external insecticides:

• dilox,
• permethrin,
• qigong and others.

Mechanical and electrical traps, as well as energized nets and gratings, are effective.

It is important to use an integrated approach, combining prevention and treatment not only indoors, but also the surrounding area (cleaning plus garbage removal, sealing cracks, and other activities).

Aerosol

This product is sold in spray cans - it is very toxic and lethal to flies. Insects die almost instantly as soon as they enter the area where this insecticide has been sprayed.

Karbofos

When using such products, it is imperative to use personal protective equipment, and after spraying, leave the room for a while. The most famous and popular drugs include: Chlorophos, Diclofos, Karbofos, etc.

Fumigators

They are devices that, using small currents, can evaporate substances dangerous to flies, from which they subsequently die.

Raptor, Raid, Mosquitol

Among the most popular are such as Raid, Raptor, Taiga, Flop, etc.

Insecticidal bait

It is available in the form of powder or granules, which need to be scattered in places where flies are most concentrated, or diluted with water and treated where insects reside.

Agita powder, against flies

This type of preparation is used in cases where it is not possible to use aerosols. Among the most effective powders is Dust, and among granules - Agita or Fly Byte.

Crayons

These are some of the most common and inexpensive blowfly repellents. They contain contact poison. Using crayons, window and door openings and room walls are treated, after which the fly in contact with the treated area will soon die.

Mashenka

To prevent human poisoning, processing should be carried out wearing protective gloves. Among the most popular crayons is Mashenka.

Prevention

Of course, it is always easier to prevent a problem than to fix it. Therefore, it is necessary to maintain basic sanitary and hygienic conditions:

• dispose of household waste in the house in a timely manner;
• do not leave uncovered food on the table;
• place a mosquito net on the windows;
• Clean pet pens regularly;
• examine animals for wounds to avoid infection with green fly larvae;
• treat manure heaps with biothermal agents;
• promptly dispose of the corpses of dead animals, as well as pests such as rats, moles and others;
• Disinfect latrines with insecticides.

Tansy essential oil repels flies, causing paralysis of their limbs. Bouquets of these flowers, hung in a livestock room or standing in a vase in an apartment, will help get rid of annoying flies for a long time.
