Nobody likes cockroaches, does not want to share their food and shelter with them. Poisons them, litters, and they all uneasy!
If there is water, a warm, secluded place, he will find something to eat for him and will begin to multiply.
We will dwell on this process in more detail, namely, we will find out how domestic cockroaches reproduce, how many cockroaches hatch from one egg, what does a pregnant cockroach look like?
How do cockroaches breed?
They are arranged wise nature in such a way that, taking a little, give a lot. Therefore, it is indestructible. You can only reduce its population.
The population is amazingly generous. Judge for yourself. Do you know how many cockroaches are born from one egg?
15-50 individuals at a time hatch from one clutch.. The female is able to make 10 clutches and more during her life cycle. It turns out that one individual is able to produce at least one hundred offspring. And they, too, will not sit on the spot - will continue to breed cockroaches. How to win? Maybe selectively destroy females?
How to determine the sex of a cockroach?
- The size. Boys, they are smaller in size.
- Wings. In males, they are more developed. The male can even fly, if he needs to get to the desired object.
- Stylus. Males have a genital plate - an outgrowth on the last segment of the body.
This is done by home representatives - ginger (Prusak) and black (like crickets). But those that live in nature - Madagascar, for example, - the males they can and hiss and wrestle with horns to get a female.

Metamorphosis
Type of development of cockroaches - incomplete conversion cycle, that is, it misses the pupal stage.
- Egg.
- Nymph - cockroach larva.
- Imago - adult individual.
- 120 days (4 months) it is necessary that the egg turned into a mature individual.
- 30 weeks imago lives and breeds.
- 300 children can give one female per life cycle.
These indicators can be higher - it all depends on the living conditions. The fuller, warmer and more humid, the more reproduction of domestic cockroaches.
Oteka like a mortgage
They waved their wings, mated. Then the most interesting begins. The female lays eggs.
These eggs she does not lay off anywhere, but in a special capsule - edema.
It is such a leathery bag that protects the eggs fairly well from damage and vicissitudes of the environment.
The female will keep this bag with her - behind the body. This edema looks like a tail, and the people call it “tail”. The female carries her edema everywhere with her wherever she leaves. And it is released from it only when the larvae are ready to go outside.
If you see such a "tail", then know that it is the most dangerous for your home. Because, dying, the female has time to throw off the “tail” - she shoots him straight, catapults. And she herself, perhaps, will die, but the "tail" is not.
How do cockroaches give birth?
The time of birth will come, and 30 small cockroaches-children, completely independent and viable, will crawl out of it somewhere, under the plinth. And you lost that little fight again.
Not myths about the nymph
To distinguish a nymph from an adult is not difficult. Larva nymph is smaller in size, its wings are not yet developedand it is of a darker color. The larva during the growth molts 5-6 times - throws off the old shell. The closer a nymph in age to a mature individual, the brighter it becomes, turning from almost black to red.
10 interesting features that make them incredibly robust:
- After mating, the gametes of the male for a long time are stored in the body of the female, and repeated laying can occur without the prior participation of the male. That is, it is enough for the female to “talk” with the male once in her life, so that later she can calmly and repeatedly leave offspring.
- Can live without a head. All his organs continue to work. But without a head the body will not last more than a week for the reason that it cannot drink and will die ... from thirst.
- May hold your breath for 40 minutes. Scientists believe that this feature was useful to him millions of years ago, when everything was not smooth with the earthly atmosphere.
- Mustaches are very lazy. They spend three quarters of their lives at rest.
- Runs very fast. If he runs, then very quickly - 4.8 km per hour. This is a lot, given the size of his legs.
- Can eat once a month. And while it may have everything. For this he has powerful jaws.
- Impossible to catch. He will feel you with all the hairs on his paws. And when it rushes to run, it will change direction 25 times in a second. You are doomed to failure.
- Withstand an atomic explosion and survive. They have a particularly slow cycle of cell division and radiation is not terrible for them.
- They have two pairs of wings. The upper ones are dense and leathery elytra protecting the body - we see them. And the lower - more subtle - hidden under the sheath. With them, he flies.
- The largest cockroach - 9 cm in length - does not live in our homes. He prefers rainforests.
Fact. Red cockroach in the fight with black - the leader:
- he quickly reaches puberty;
- more prolific;
- takes better care of its offspring and even feeds on its opponent's eggs.

How to stop reproduction?
In order to prevent the cockroaches from breeding, strip them of the main thing they love:
- Heat. To exhaust the dwelling for a while. In the old days they did it - they relaxed the hut, insects are dead, unable to endure human cunning. Such were the popular methods.
- Water. They can not not drink. Therefore, in the apartments they cling to the water supply, kitchen, sinks.
- Food. Build cleanliness in the cult. No crumbs, scraps, overflowing trash cans. Although in this case, the cockroach goes on paper. He is almost omnivorous.
In addition, measures should be taken to expel uninvited guests from home. There are a lot of different tools, ranging from crayons like Masha, dust FAS, Clean house ending traps Combat, Forsyth and aerosols Raid, Raptor, Get, Hangman
And in general, in the old days it was believed that cockroaches are a sign of prosperity. If there is nothing for people in the house, then the mustache has no place there. So, we should not be too harsh to such a talisman of our welfare.
