Blood-sucking insects cause a lot of trouble for humans. Indoors, we may be bothered by annoying squeaking, especially in the evening. Bites, although they do not pose a great danger to the body, cause itching and pain in the area of the skin.
Various methods are used to protect a home.

Danger
Where do mosquitoes come from? They enter a house or apartment through open doors, windows, cracks and cracks. If a female mosquito laid larvae in the warm season, this question disappears by itself. Mosquitoes are not at all harmless insects. In addition to the fact that they make unpleasant annoying sounds, bite and prevent you from falling asleep at night, mosquitoes often become carriers of dangerous diseases, infections and allergic reactions.
These insects attack several people at once. Therefore, they can easily transfer an infection from an infected person to a healthy person. They are the cause of malaria, tularemia, yellow fever, and lymphatic filariasis. In addition, a mosquito bite itches. Sometimes such trauma to the skin leads to the appearance of scars.
Peculiarities
Where do mosquitoes come from and how long do they live after they bite? Most often, these insects enter the house from the street, where they breed. That is why they cause so much inconvenience to humans in winter. Mosquitoes are weaker and easier to kill. The mosquito attacks a person as soon as it senses him. An insect can hunt for a long time, because its main goal is to bite.
During a bite, a kind of exchange occurs: the mosquito takes blood from its victim and gives saliva. It prevents coagulation and the insect is able to “enjoy” its prey for a long time. The substance found in the mosquito’s saliva causes discomfort at the affected area, causing redness and itching. It causes severe allergic reactions in people with sensitive skin. The lifespan of female mosquitoes is approximately forty to one hundred days. It all depends on the ambient temperature. Males live much shorter lives.
A brief introduction to insects
Mosquitoes (other “official” names are true or blood-sucking mosquitoes) - from the point of view of biological classification, they are the family Culicidae, assigned to the group of Long-whiskers and the order of Diptera insects, which are characterized by sexual reproduction and complete transformation (metamorphoses from egg to adult: o These will be discussed in detail below).
Adult female mosquitoes drink human blood and are part of the midges - a group of blood-sucking insects, for which they have earned strong dislike from people
Mosquitoes are small flying insects. The length of their thin and soft body varies from 4 mm to 15 mm in different species. All representatives of the family Culicidae are characterized by the presence of long legs, which end in 2 claws for better grip on surfaces and stability, and narrow transparent wings, consisting of many caps. Their span ranges from 5 mm for the smallest species to 30 mm.
In tropical regions there are real giants: for example, long-legged mosquitoes, or caramors, in favorable conditions they grow up to 10 cm in length, which is a record figure.
Most species of the Mosquito family have a nondescript color: gray, brown, yellow. Much less often (and mainly in southern countries) black or green specimens are found. The thoracic region of insects is wider than the abdomen. The long antennae, necessary for orienting the insect in space, are formed by 15 segments.
The mosquito's mouthparts are a piercing-sucking type. It is hidden in the lower lip of the insect, which is shaped like a tube. Inside it are sharp jaw stilettos, similar to blades. They are needed to cut a microscopic hole in the skin, through which the sucking proboscis then penetrates to the layer of capillaries. Moreover, in females it consists of piercing bristles, which are absent in males.
By the word “mosquito,” people most often mean the squeaky mosquito. It is he who annoys people with his obsessive buzzing and painful bites.
In total, the Mosquito family has 3,000 species, divided into 38 genera. Most of them live in southern countries with a tropical climate. Only 100 species, representing 3 genera, live on the territory of Russia: true mosquitoes, biting mosquitoes and malaria mosquitoes.
Kinds
Where do mosquitoes come from after winter? Most often, these insects lay eggs in apartments, entering them through basements or stairwells. It is not difficult for them to get into living quarters, especially during peak migration periods. With the onset of spring and sharp warming, their activity increases. There are about three hundred species of mosquitoes in the world. The most dangerous is malaria. The threat is that they can feed on the blood of dead animals and then move on to humans. The following are the types of these blood-sucking insects:
- Squeak mosquito. The most common type that quickly adapts. This mosquito is wild, lives in forest areas, parks, but is also found in cities. Some mosquitoes of this species have adapted well to civilization; they are able to reproduce in extreme conditions. “City ones” do not hibernate, so they are easy to meet even in winter.
- Malarial. A tropical mosquito in whose stomach small worms develop. When bitten, they enter the human lymphatic system, where they multiply.
- Tigers. This species also poses a danger to humans and becomes a carrier of dangerous diseases and infections.
Where do big, non-biting mosquitoes come from? These insects frighten people with their appearance. They are also called centipedes. The large species lives in the wild, near water bodies. Almost never found in cities.
Fumigants
Today, fumigants are the most common means that reliably help against mosquitoes at home. From Latin the word fumigo is translated as “fumigate”, “smoke”. From this it becomes clear that this category consists of products that, when smoldering, smoking or evaporating, release substances into the air that destroy insects. Moreover, the action of fumigants is aimed precisely at the destruction, and not at repelling, mosquitoes. In most specialized stores and even supermarkets you can now purchase electric destroyers, or fumigators. Among the most popular manufacturers of these products are Raptor and Raid. The principle of their operation is quite simple: a special device must be plugged into an outlet, and from electricity it begins to heat a plate or liquid soaked in an insecticidal substance. Usually, the death of mosquitoes in an apartment occurs within half an hour. Fumigators are designed to fight mosquitoes in the apartment at night. One fumigator plate is enough for 8-18 hours; fumigators with liquid insecticide are designed for a longer action - up to 45 nights.
Such products are usually based on pyrethroid insecticides, the most common being prallethrin and esbiotrin. Experts recommend buying fumigators based on prallethrin, since it is safer and is used in lower concentrations. This substance is a synthetic analogue of Dolmat chamomile extract, which is used even for children's fumigants.
Despite their high effectiveness, such mosquito repellents in apartments also have a number of disadvantages. Firstly, not everyone uses them correctly. It is worth remembering that the effect of this product is designed for an area of 12 square meters. m. The fumigator is turned on in a room without people, wait half an hour, ventilate the room and turn it off. In our country, they often leave it on all night, almost at the head of the bed. fighting mosquitoes in your apartment should be safe for you. Although these products contain small concentrations of insecticides, they cannot be called completely safe. Fumigators are not recommended for use in rooms with children or pregnant women, as well as with people who have respiratory tract diseases.
Also, you should not use the fumigator with the windows closed, which is quite difficult to imagine on hot summer days.
Where do mosquitoes come from?
The answer to this question interests many people. Mosquitoes are nocturnal insects. They reproduce quickly and are most active in humid and warm environments. They choose wet, warm and damp places to live. Where do mosquitoes come from in houses? These insects are common not only in rural areas, but also in cities. Their favorite habitats are basements of high-rise buildings, balconies, bathrooms, and garages. They often hide under suspended ceilings. During the day, mosquitoes are practically inactive. At an air temperature of 0 degrees, insects fall into so-called torpor.
Insects appear in city apartments in spring and autumn, when the temperature outside is still or no longer comfortable for them. Sometimes mosquitoes become active in winter, crawling out of basements and secluded places. They accumulate where there is a lot of water. They enter apartments through ventilation, elevator shafts, staircases, and garbage chutes.
Interesting Facts
Reproduction is impossible without saturating the females with human blood. Therefore, mosquitoes are spread over almost all areas of land where humans live. They stay close to settlements so that they can drink the blood of people at any time.
Each species has its own preferences in temperature and lighting conditions. Some people like shady ponds, others like well-lit ones. Biologists have calculated that the larvae are able to develop when the water temperature is 10–35 °C, but between 25 °C and 30 °C is considered most comfortable.
Mosquitoes rarely lay eggs in large bodies of water where many fish live, because they readily feed on eggs.
The larva will die if the water is contaminated with oil products: they form a film on the surface through which the worms cannot breathe. But some species show enviable adaptation, having adapted to use oxygen dissolved in water for breathing.
The process of how mosquitoes appear has been sufficiently studied by science. These insects are characterized by high fertility and feeding on human blood. Both of these traits are directly dependent on each other.
Causes
Where do mosquitoes come from? Their appearance in a house or apartment is not related to the arrangement of life and other factors. The specificity is that they always settle next to a person. The main way they spread is migration. Insects breed close to a food source. The appearance of mosquitoes in the city is due to rainy and warm weather. They enter apartments from the street, especially if the summer is rainy and warm.
During unfavorable periods (drought, severe cold), they wait in shaded, as humid places as possible. Mosquitoes often hide in houses and apartments:
- in curtains, on ceilings or walls - where there is little light;
- behind pictures, cabinets, under carpets;
- in window frames, narrow cracks.
Mosquitoes breed in dark and damp places. However, the survival rate of larvae in residential areas is low.
How to get rid of it?
Where do big mosquitoes come from? Despite their terrifying appearance, they are absolutely harmless to humans. These mosquitoes do not attack and live in forested areas and wetlands. If they fly into a living space, it is by accident. They are usually attracted to warmth and bright light. There are many ways to get rid of insects: chemicals, traditional methods, or calling specialists to your home. Natural remedies are considered one of the safest and most effective. For example, a sprig of elderberry and the smell of walnuts and pine nuts can drive mosquitoes out of your apartment forever.
Ultrasonic protection
Another very effective method of saving your home from mosquitoes is the use of ultrasonic repellers. The action of these devices is based on the generation of ultrasonic signals that repel mosquitoes.
Ultrasonic protection has many advantages:
- does not emit unpleasant odors;
- there are no secretions dangerous for humans;
- works absolutely silently;
- Ultrasound of this power is completely harmless even for infants;
- does not interfere with the operation of home equipment.
When purchasing an ultrasonic device, you should correlate its radius of action with the size of the room in which the device is intended to be installed. Otherwise, only part of the room will be protected.
