Теперь занимаюсь всем сама. Докажу мужу, что он ошибается. Сначала хочу понять, как развиваются паразиты, сколько времени это требует, когда потомство становится половозрелым, начинает откладывать яйца. Я интуитивно понимаю, что только теория поможет на практике вывести кровососов, т. к. пока мы действуем вслепую. Например, зная, как быстро размножаются клопы постельные со дня появления в квартире, я могу понять, когда нужно проводить повторную обработку. Расскажите о развитии кровососов, пожалуйста. Мы с мужем будем признательны вам. Сара.

In my material below, you will learn how bed bugs breed and how to prevent their spread.
The life cycle of bed bugs from larvae to adults
Insects continue to exist for 12-14 days. This is the average lifespan, but it may increase or decrease depending on the parameters of the air environment. The rate of development increases when the microclimate is warm. If bed bugs find themselves in a place where it is cool, their lifespan will increase. Then the insects will live 1.5 times longer (for 18 months, sometimes 2 years).
This is explained by the ability to go into a state similar to anabiosis in its properties. It is called diapause. Such state is accompanied by inhibition of metabolic processes. As a result, there is no need to eat, mate, as well as other activities.
The insect throughout the diapause period remains resistant to high and low temperatures, insecticides, and humidity.
The parasites belong to a group of pests with an incomplete transformation cycle, which means it is possible to skip pupation. Bed bugs have only three stages of development:
- eggs;
- nymphs;
- imago (sexually mature individuals).
And the second stage of development is divided into several stages according to its age. At each of them, the nymph undergoes molting.
Mating
In this case, nature provides a cruel method of insemination on the one hand, but on the other hand it provides the only possible method for the survival of the species - a traumatic insemination that is implemented forcibly, without the approval of the female. The male traumatizes her abdomen with his sexual organ and injects seminal fluid into one of the Berlese organ compartments.
It is important not only to understand how mating bedbugsbut also to find out why nature provides for such a method. For example, when there is no human around for a long period of time, bed bugs need nutrients to survive. They get them by digesting half-formed eggs.
Thanks to forced mating, the female always has a source of food in case of starvation.
Eggs
Per day bedbugs lay anywhere from 1 to 12 eggs. It depends on the amount of food consumed and the environmental conditions. Normally, a female lays 5 eggs per day. She leaves them in hidden areas, fixing these formations on different surfaces, even flat and smooth. This peculiarity is explained by the fact that together with the egg a sticky substance is released. Thanks to this method of laying, the offspring is well protected. The incubation period in bed bugs lasts from 7 days to 2 months, which depends on environmental conditions. However, the average duration is 2 weeks. Eggs are white formations up to 1 mm in length, with a light (milky-white) hue.
Nymphs - larvae
At the end of the incubation period appears worm, nymph. It is necessary to understand the difference between these concepts. So, a larva emerges from the egg, its body size corresponds to the parameters of the egg. It becomes a nymph after the first molt. Then Insect goes through several more stages of maturation. The bug is still a nymph. The insect is similar to an adult bedbug in a number of ways. The only difference is the size of the body. The young grows 0.5-1 mm larger on each of them.
Moulting occurs after receiving a portion of blood.
Adults
When bedbug The insect is called an imago when it completes its development and the next phase of its life begins. Males are of medium size (0.6 cm), females are larger, they can reach 0.8 cm. Only when the insect enters this phase of the development cycle does it acquire the ability to reproduce. In addition, only the imago can anesthetize the bite site; the nymph has not yet developed this function.
Main breeding sites
The female can leave her offspring not only in places of permanent residence (which are conventionally called nests). She hides her eggs wherever she finds a suitable place for them: in cracks in various coatings, in furniture.
Reproduction rate and area affected by bed bugs
Bedbugs - pests with great capacities (according to their species). They are able to reproduce throughout the year, unlike many predators and herbivorous insects. Eggs are formed in a few days in the body of the female. Larvae emerge after 4 to 19 days. Life cycle bed bug The period of time during which the insects have time to multiply significantly, respectively, their nests also increase.
When the insects become crowded in one area, they find a new place, so the whole room can be infested, as well as neighboring rooms.
Factors that inhibit reproduction
In home conditions, there are sometimes obstacles to the full formation of insects. The parasites lose the ability to reproduce and feed, which also affects the reproduction of bed bugs.
Low and high humidity
The parasites do not tolerate extremely low or high air humidity values. Adult insects and offspring suffer in this case. Egg clusters dry out if they are in a room with low humidity for a long time. It should be understood that the life cycle of bed bugs is also shortened if they are exposed to high humidity.
As a result, a fungus develops on the chitinous covers, it hastens the onset of death of the pests.
Low and high temperature
Indoors, parasites are more likely to die from heat than from cold. They die when exposed to temperatures over +45°C. When it gets colder to +19°C and below, the development of bed bugs slows down. But they still live. When temperature decreases to +5°C, the parasites go into diapause. Death occurs at -17°C, but not immediately, but gradually. Parasites die instantly at -25°C and more.
Prolonged absence of food
At the same time, insects maintain their existence by inhibiting metabolic processes in their bodies and by eating half-formed eggs. This is enough to preserve life.
However, more food, and therefore more energy, is needed to reproduce.
Eternal problems from one bedbug
The Berleza organ stores spermatozoa that got inside during traumatic insemination. This allows the female to reproduce without the male being involved in the process. Even if she gets into a place where there are no insects of the same species yet, the breeding process of bed bugs in the apartment begins.
Bedbugs appeared in the house - they will immediately begin to multiply
In order to form and develop offspring, food - the blood of a warm-blooded creature - is required. To provide this possibility, insects go in search of a new home.
The effect of rapid multiplication
The frequency of eating is constantly changing. It depends on whether a person is available for attack, whether they have managed to crawl in at night, and whether there is enough food for all the insects. It is also important to understand how bed bugs reproduce. Thus, it requires a portion of blood. Sometimes (under favorable conditions) the female makes a clutch every day.
Then the appearance of a large number of parasites in a short period of time is ensured.
Inbreeding - the secret of bed bugs' superbreeding ability
The term refers to the ability of parasites to produce offspring due to the crossing of closely related insects. There is no mutation or other serious changes at the genetic level. Scientists are still unable to explain this phenomenon, but it has enabled this species to survive under various conditions. Bed bugs sometimes even mate with nymphs and males, but they do not produce offspring.
Can a bedbug reproduce alone
Parasites have many chances for the survival of the species because the female reproduces offspring, even long after mating. However, if a single male enters the room, this effect is not ensured. Without a female, the reproduction process is inhibited.
How regular feeding saves the female from dying after mating
Regular nutrition (when some regularity is observed) stabilizes the function of the immune system. As a result, traumatic insemination reduces the risk of infection and death if bacteria also enter the body through the damaged covers. Those females that feed without reference to the biological clock, but depending on the circumstances, risk death due to infection.
Fighting parasites
It is important not only to understand how bed bugs reproduce, but also to do everything possible to prevent the appearance of insects in the apartment. To do this, preventive measures are used. If an infestation has already occurred, measures should be taken to prevent them from spreading.
How the house is infiltrated
Perhaps 2 options:
- forced spread to neighboring houses, apartments (occurs purposefully) for a variety of reasons: lack of food, habitat; bed bugs poisoning when treating the entire room;
- accidental ingestion together with pieces of furniture, closet, in suitcases.
Pathways of ingress parasites home to humans:
- gaps in the window and door units;
- cracks in the walls, floor;
- cracks in the areas where communications are brought home;
- ventilation duct.
Prevention
To prevent the appearance of vermin, it is necessary to block all paths of their entry. To do this you will need to repair the floor, walls, frames, door unit (surface renovation is sufficient). In addition, deterrents are used:
- essential oils;
- bitter herbs and other strong-smelling plants;
- household chemicals (VinegarThe use of such substances is moderate, because such substances have an effect on people, not only on parasites.
Deliverance
Methods are used to eradicate insects:
- Insecticide-based bed bug remedies: household remedies (Raptor, Dichlofos, Combat, Get etc.), professional methods (hot, cold fog);
- temperature effect - fast results provide superheated steam (apply steam generator), you can fill the nest with boiling water.
The best result provides a combined housing treatment scheme.
It is possible to get rid of insects at home in a short period of time if you simultaneously use several different types of remedies and methods.

Video tip (video): the reproduction cycle of bed bugs, how not to miss the moment of mating and get rid of bed bugs quickly
My personal story "How I fought one bedbug and got a hundred"
"When I started to remove bed bugs, I did not know much about these insects. I tried to get rid of the parasite quickly, so I made a lot of mistakes. Now I am a master, in this business, but in the end my furniture and psyche suffered. It all began with the appearance of single bites. Immediately in the morning I assumed the appearance of bedbugs by the description. The apartment is small, I searched all over, but found nothing, I thought it was only the first parasite.
I poisoned with insecticide (powder, all the time with the same insecticide). This was my main mistake, who knew that bed bugs do not respond to such methods, they will continue to multiply. After a week, there were many more bites and an unpleasant smell. Then I already used aerosol, and I changed preparations, but it did not help. There were already a lot of parasites, I had to call the exterminators. The time that I spent on the wrong fight, bed bugs spent on development, reproduction, feeding".

Tips from the experts
- use deterrents, such as placing cotton disks with essential oil inside the sofa or sprinkling the surfaces with a solution, this will help scare away the first pests;
- at home where there is constant noise, the risk of infection is lower, because parasites do not like constant exposure to sound.
Conclusion
When bedworms appear, you need to learn all about them. This will help you get rid of them quickly. Features of such insects:
- The life cycle lasts 1 year, sometimes more or less, depending on environmental conditions;
- The incubation period is 2 weeks, after which larvae emerge from the eggs and turn into nymphs and then into adults. Insects of this species undergo an incomplete development cycle.
- Females can reproduce without males. And bed bugs mate even with those of their fellows who are their close relatives.
