What is the reason why cockroaches are rampant in the home in general?

Cockroaches, commonly known as cockroaches, are common medical insects, belonging to Arthropoda, Insecta and Cockroaches.

Cockroach is a kind of living creature with strong viability. According to its ecological habits, a biologist once concluded that if there is a global nuclear war on the earth one day, all creatures in the affected area, including humans and even fish, will disappear, and only cockroaches will continue their lives!

However, in terms of radiation, under normal circumstances, the radiation that the human body can tolerate is 5 rem, and once the total radiation exceeds 800 rem (radiation dose unit), it will die. Blattella germanica can tolerate 9000 ~ 105000 rem, and Periplaneta americana can tolerate 967500 rem.

It can be seen that the survival ability of cockroaches is far stronger than that of human beings, and even nuclear war is not enough to threaten the survival of cockroaches. This characteristic of cockroaches also makes cockroaches parasitic in human houses a nightmare for many people day and night.

In the impression of many people, cockroaches appear at home because they are not cleaned up, and they think that cockroaches can only live in dirty corners. In fact, this is a wrong cognition. Cockroaches appear at home for various reasons.

First of all, cockroaches are omnivorous creatures with a wide range of food. All kinds of food, including bread, rice, cakes, vegetarian and cooked food, melons and fruits, drinks, etc. I especially like delicious, sweet and oily pasta. In particular, some vegetable oils are very attractive to cockroaches, and these things are the necessities of human life at home.

Moreover, cockroaches are very fertile, which is a combination of sexual reproduction and asexual reproduction. A mature female cockroach can produce an egg sheath containing 14-40 eggs every other week or so, and a female cockroach can breed nearly 10,000 offspring a year, up to100,000.

Under extreme conditions, female cockroaches can lay eggs without male cockroaches. In other words, many female cockroaches will be hermaphrodite once they mate, and they can lay eggs continuously without mating.

Therefore, as long as cockroaches appear near the residence, such as cockroaches accidentally carried by neighbors when traveling, they will multiply rapidly and spread to the surrounding areas. Because there are a lot of food that is fatal to cockroaches in human houses, and the temperature is more suitable for the reproduction of cockroaches, human houses will become the first choice for cockroaches to settle down.

In addition, sewage pipes extend in all directions in the city now. As long as cockroaches appear in one family, these small insects can flow to all the nearby houses through sewage pipes. So once cockroaches appear at home, it is not enough to just kill them at home.

It is worth mentioning that the American government spends as much as1500 million dollars on cockroach control every year, but up to now, the American government has still not been able to get rid of the harassment of cockroaches and is still at a loss.
