Bedbugs are a real disaster in a modern apartment.
Their main problem lies in the incredible fecundity - it is enough to get into the room of one female, capable of laying eggs, and after a while a whole colony will live here.
And when destroying pests, it is necessary to show increased attention, since the uninhabited population is able to recover very quickly.
Today we will find out how quickly bedbugs breed, what bedbug eggs look like, photos are attached, where do they lay them and how many hatch? Stages and type of development, as well as the incubation period.
How do bedbugs breed in an apartment?
The process of breeding bedbugs - bedding, linen, home filled with unique details that are not present in other insects. Because of this, this action is of great interest to scientists.
The distinguishing feature of the breeding process for domestic bugs is traumatic fertilization. During this time, the male inseminates the female, not with the consent of the latter, but by force. At the same time, he punches the abdomen of the female with his own sexual organ, and injects seminal fluid there.
This method was developed in domestic bugs in the process of a long evolution. Permanent egg formation ensures that, even in the event of a hungry period, the female will be able to use them as a source of food and thereby survive.
The seminal fluid received from the male is placed in a special reservoir, from where it is used for the entire time.
Thereby an adult female does not need a male in order to create a population in a new place.
Male bugs in their desire to multiply behave very aggressively. They do not spend much time choosing a partner, so there are cases when the males attacked other males, larvae in the nymph stage, and sometimes even cockroaches. The analysis carried out by scientists showed that almost all members of the nest, regardless of their gender or age, have characteristic damage to their abdomen.
Eggs bed bugs. After fertilization, the female will postpone up to 10 eggs per day. Up to this point, they are about 4-5 days mature in her body. Eggs are long no more than 1 mm, they are white and elongated, recalling the shape of rice grains.
Placed in the nest, which is usually located in the folds of the mattress and under it, in the bed frame, under the carpet or picture. It is sure that it is located as close as possible to the person’s place of sleep in order to minimize the time it takes to reach the place of feeding.
Eggs are usually arranged in large groups, which include tens and sometimes hundreds of pieces. At the same time, its shell is strong enough and able to resist external influences.
For example, some types of poisons and aerosols can not penetrate through it to the embryo. Because of this, when poor-quality processing, insects can reappear in 1-1.5 months.
In order to regularly lay eggs, the female needs to eat constantly and efficiently. One meal is enough for about 20 eggs. And just for the entire period of life, the female has time to produce from 300 to 500 pieces.
ATTENTION! The best conditions for constant reproduction are located in residential apartments - a large number of places for shelter, protection from sudden changes in temperature and constant presence near food.
Below is a photo of bed bugs eggs. You can evaluate what they look like:
Bed bugs larvae. After 3-4 days after the egg comes out of it a larva appears, or a nymph. It looks like a reduced full-fledged bug, but is completely incapable of breeding.
In the process of development, the larva is constantly increasing in size, and because of this it has to shed regularly, because its own shell does not know how to stretch. Total for the period of development to a full adult state, nymph molts 5 times.
In order for the process to proceed normally, it needs at least once to drink blood to the entire volume of the stomach.
In favorable conditions, molt occurs every 6-7 days, so after 1.5 months the larva turns into a full-fledged insect.
That is, from the day of the appearance in the apartment, if one or several bedbugs appeared, after a couple of months there may already be a full-fledged colony of parasites. And then they spread very quickly.
However, if the temperature at the place of residence of bedbugs begins to decrease, the process of development slows down. At room temperature + 15-20 degrees, a full cycle will take 3 months. When it falls less than +15 degrees, the larva will fall into an anabiosis and will wait for conditions to improve.

Development and life cycle
Bed bugs are insects with complete transformation. Their life cycle consists of three stages - eggs, larvae and adults. The latter lay eggs, after which the cycle begins a new round.
How many live bugs, bedding and linen? The lifespan of parasites is directly dependent on the ambient temperature. If it is optimal, then the adult can live 10-12 months. In this case, in a cool room, the term is increased to 1.5 years, and in a hot room - from +30 degrees, it decreases to 6-9 months.
Occupation of bedbugs depends on their gender and age:
- The males in the process of life constantly trying to fertilize any female;
- The uterus is engaged in laying new eggs;
- To ensure growth, larvae feed almost continuously.
If a permanent source of food disappears, the bugs either change their habitat or go to state of hibernation. During the latter, all processes in the body of an insect slow down, and he is in a deep sleep, which can last up to 1 year.
During this period, you might think that the insect is dead, but when it comes into contact with a person, it can almost instantly come to its senses and start drinking blood.
Bedbugs are insects with a cycle of complete transformation. Males force insects on females, which then begin to lay eggs all their lives (300-500 pieces of all time). Larvae (children) appear from the eggs, which molt every 6-7 days and almost all the time they spend feeding.
They grow into adult individuals ready for mating, which live in optimal conditions for up to 1 year. Due to the short time of development, a colony of bedbugs can very quickly increase their numbers.
