Green flies in the house: what to do?

8 minutes. for reading

Flies in our house cause discomfort with their intrusive presence: they buzz, crawl on food and things, causing disgust. However, the main reason for their elimination is their ability to spread infections and spoil food and belongings.

All about green flies: appearance, development, reproduction

The green blowfly is a species of fly that prefers warm places and lives in the steppe, semi-steppe and semi-desert zones of Eurasia. In hot years they can spread much further. Adults of this species range in size from 5 to 10 mm and have a green body with a metallic sheen, and a light white coating is visible on the abdomen. The green fly has yellow tentacles and black legs, and males and females differ slightly in structure. These flies are most active in the summer.

The life cycle of a green fly includes several stages. First there are eggs, which have an elongated oval shape and are white in color. The size of the eggs depends on the number of eggs in the clutch, and they can withstand wide variations in temperature and humidity. This is followed by a larval stage, which can reach a length of up to 19 mm and develops on animal carcasses or in meat waste, food waste, manure and feces near people. The larvae undergo three molts and become prepupae, which eventually develop into pupae. The pupae are reddish-brown, dark brown or black in color and remain in this state for up to 5 days. They then develop into adults, adults, who are active immediately after metamorphosis and can fly. Adults are found in populated areas, especially in markets selling fresh meat, fish, fruits and vegetables, and in slaughterhouses. Adults live up to 1,5 months.

The overall developmental cycle of this fly usually lasts up to 2 weeks, but can vary depending on environmental conditions. Female green blowflies can lay up to 150 eggs at a time and prefer different types of growing media, such as meat waste, body wounds, animal hair, fish (both fresh and lightly salted), excrement, garbage containers and others. In the warm season, the green fly is capable of producing several generations, and if it gets into closed, heated rooms, its activity can manifest itself all year round, without wintering.

Reasons for the appearance of flies in apartments and private houses

Flies getting into the home is a common problem and the main ways they enter include open summer windows, missing mosquito nets on windows and holes in existing screens. However, it is surprising that these unpleasant insects can settle in apartments in winter or autumn. But why is this happening?

Comfortable temperature conditions in modern apartments are one of the reasons. Flies prefer warmth and, when they enter an apartment in the summer, adult flies begin to actively reproduce and leave egg layers. Thanks to moderate warmth, they do not hibernate, which ensures their continuous life cycle.

Another factor that encourages flies to enter is high humidity. Leaky kitchen or bathroom faucets can attract these insects, providing them with additional sources of moisture they need to survive.

Poor cleaning and food storage habits can also create the perfect environment for flies. If you don't take out the trash regularly, leave food out in the refrigerator without proper cover, or leave dirty dishes out, it becomes food bait for flies, giving them an opportunity to breed.

The presence of cracks in the floor, ceiling or walls provides flies with ways to enter the house. These small openings act as gateways for pesky insects, especially if they are located close to the kitchen or other food sources.

Improper storage of fruits and vegetables can also cause flies in your home. Rotting fruits attract pests, which quickly begin to multiply if the problem is not resolved in a timely manner.

Even indoor plants can become a source of concern. In the summer, flies can lay eggs in potted plants, and then new flies hatch from these eggs. It is also possible to accidentally purchase an already contaminated soil mixture, which contributes to the spread of insects.

Close proximity to grocery stores and food outlets means that flies can easily enter your home through ventilation and drains, which is an additional risk factor. In addition, insufficient care of the local area and untimely garbage removal create excellent conditions for the breeding of flies.

Additionally, the quality of the products you purchase can play a key role. If you accidentally buy food that is contaminated with fly maggots, especially meat or fish, it could be the source of an infestation of black flies, also known as carrion flies.

Finally, external factors, such as the presence of animals or pets, can bring parasite larvae or eggs into your home from the street. These unpleasant guests are capable of bringing flies inside, which becomes a problem that requires a quick solution. The spread of these insects into a person's home can have serious consequences, and therefore it is important to immediately take measures to destroy them and prevent new invasions.

How dangerous are flies to humans?

Most species of these flying pests, including green flies, are constantly in contact with garbage, feces and food waste. This is why their paws can harbor dangerous infections and pathogens.

There is a risk of serious food poisoning if you eat food contaminated with parasitic larvae. If the larvae get into wounds on the body of animals or humans, they actively develop, corroding living tissue.

Flies multiply and spread throughout the apartment very quickly. Many of them have aggressive behavior, and their bites can cause severe allergic reactions and irritation. To avoid many problems, it is important to get rid of these parasites in your apartment as soon as possible.

How to get rid of flies in the apartment

Now that you know where and how flies come from indoors, it is important to know how to deal with them. There are several methods to combat these pests, including the use of folk remedies and chemicals.

The main methods of controlling flies include preventive and exterminatory measures. Extermination measures include mechanical and chemical methods of exterminating insects.

Preventing the appearance of flies in residential premises

When it comes to protecting our homes and apartments from flying parasites, it is important to adhere to a certain order and observe the rules of hygiene.

To prevent the spread of flies, it is important:

  • Keep tables and other open surfaces clean, avoiding food, crumbs, dust and debris.
  • Wash dishes immediately after eating.
  • Carefully check the condition of vegetables and fruits, getting rid of spoiled specimens.
  • Check your plumbing regularly and promptly fix any leaks.
  • Control indoor humidity.
  • Take out trash regularly, preferably using closed trash containers.
  • Block the paths for insects to enter the room. Close doors during hot weather, install protective screens on windows, and fill cracks in walls and floors.

Remember that it is easier to prevent pest infestation in a room than to deal with its consequences later. Keeping your home tidy and clean will play a key role in this process.

Mechanical pest control

Mechanical control methods do not form the basis of disinfestation against flying parasites, however, these additional techniques can significantly speed up the complete ridding of your home from these pests.

Mechanical control methods include:

  • Thorough and regular cleaning.
  • Using mosquito nets on windows.
  • Using fly swatters.
  • Setting baited traps.
  • Using adhesive tapes lubricated with substances that attract insects. You can make such tapes yourself by smearing thin strips of paper with rosin or resin, adding sugar and vegetable oil to attract parasites.

These methods complement other methods aimed at completely eliminating parasites in the house. However, without the use of industrial insecticides, such products may be ineffective.

Chemical disinfestation

Various emulsions and aerosols can destroy not only adult parasites, but also their larvae and pupae. Poisoned food baits are also widely used. When purchasing household insecticides, it is important to carefully study the instructions, strictly follow all instructions and be sure to use personal protective equipment. This will help avoid accidental inhalation or drug poisoning.

The effectiveness of treatment largely depends on the number of flies in the room. Please note that some drugs may cause an allergic reaction.

It is important to remember that during the treatment of the apartment, it is better for children and pets to temporarily leave the premises. After using aerosols, it is necessary to thoroughly ventilate the room.

What to do if there are flies in your apartment: professional control methods

We have already said that a female fly is capable of laying up to 150 eggs at a time, and not all available household insecticides are capable of completely destroying them. Over time, larvae and then adult flies appear, and the treatment has to be carried out again and again.

This is not the only problem when trying to get rid of flies in the house on your own. What to do if a lot of effort and time have been spent, but the parasites have not disappeared? In this case, professional disinfection companies come to the rescue.

How to Get Rid of Blow Flies (4 Easy Steps)


Where do green flies come from in an apartment?

These insects enter the room in the summer if the windows are not closed or protected with special nets. How can flies get into enclosed spaces? Most likely, the parasite eggs were brought into the house along with food. Flies can also be carried inside the house on the legs of pets after a walk.

How can you repel green flies?

The flies are repelled by the pungent smell. In places where they accumulate, you can place aromatic fresh or dried plants (mint, lemon balm, lavender, bay leaf). You can also use essential oils by adding them to the water when cleaning. Drops of essential oil on cotton wool wiped across window sills and baseboards can also repel flies and other parasites. Ammonia is another effective odor repellent for flies and other household insects.

Which product is most effective against flies?

Traditional methods can be effective only in the early stages of infestation of a room with flies. Fumigators, traps, tapes, fly swatters and aromatic products can help if there are not too many house flies yet. However, a faster and more effective solution would be to use household insecticides. If even these measures do not help, there is no need to waste time - it is better to contact a professional disinfection service.

Where can flies lay eggs in an apartment?

To understand this, it is important to consider that flies are attracted to any food environment: produce, meat, fish, vegetables, fruits, dirt in flower pots, garbage, even pet feces. Therefore, it is important to maintain cleanliness, remove food in a timely manner, wash dishes, take out trash and regularly carry out wet cleaning.
