How many cockroaches are there in this world? No one knows the answer, and humans can't count the exact numbers. But what is certain is that wherever people are, there are cockroaches. Or rather, they can live well without humans. 
Come to the app to enjoy HD**Come to the app to enjoy HD** as early as 3In the Carboniferous period 200 million years ago, cockroaches were already active on the earth, before the appearance of dinosaurs. In the past hundreds of millions of years, cockroaches have experienced many mass extinctions and witnessed the rise of human beings.
12.5 billion years ago, Cretaceous fossils show prehistoric cockroach fossils, whose abdomen is ready to lay egg sheaths The most common cockroaches in the domestic home are mainly 6 species: German cockroach, American cockroach, black-breasted cockroach, brown-spotted cockroach, Australian cockroach, and Japanese cockroach.
Among them,German cockroachIt is also known as the "northern cockroach", which is smaller in size, only about 1 centimeter.
But the American cockroach, known as the "southern cockroach", is different, with a body length of up to 5 centimeters and a shiny and shiny body"You have to see even the leg hair clearly".
Adaptable:Cockroaches are highly adaptable, able to adapt quickly to different environments, and are even able to resist some conventional pesticides.
For example, the German cockroach in the United States is resistant to most pesticides and can survive in a variety of environments, including human homes, schools, hospitals, and restaurants.
Strong reproduction:Cockroaches are very reproductive, and a single female cockroach can produce up to 400 offspring. This makes them very numerous and difficult to remove completely. For example, the number of eggs laid by females of the German cockroach can reach 40-50 eggs at a time, and a female cockroach can produce hundreds of offspring during its lifetime.
Nocturnal:Cockroaches are usually active at night and hide in hidden places such as wall cracks, pipes, and kitchens during the day, making it difficult to detect and eliminate. For example, the brown rotten cockroach in the United States is mainly nocturnal, hiding in hidden places such as corners, garbage bins, pipes, etc.
Exoskeleton:Cockroaches have hard exoskeletons on the surface of their bodies that protect their internal organs from damage. This makes them less susceptible to pesticides. For example, the exoskeleton of the Asian brown rotten cockroach is particularly hard, which prevents the penetration of pesticides.
Longevity:Cockroaches have a relatively long lifespan and can survive from a few months to a year or so, which gives them enough time to reproduce and acclimatize to their environment. For example, the German cockroach in the United States has a lifespan of about 100 days, but is able to produce a large number of offspring during this time and quickly adapt to different environments.
Therefore, for the health of our families, we must "kill all cockroaches"!
Insecticides, super glue, poisons and other means have been exhausted, and cockroaches have always been difficult to exterminate, which is closely related to the cockroach's own reproduction. Generally, when we see cockroaches, we will directly step on them, butIn fact, cockroaches can't be trampled to death with their feet, why?
There are two reasons for this:
1. Stepping on a dead cockroach, but not without stepping on the eggs in the cockroach's body
As one of the four major public hazards, cockroaches carry up to 40 kinds of bacteria in their bodies, which will pose a serious threat to our health"The more you step on it, the more you step on it".Target.
Cockroaches are also divided into male and female, and it doesn't matter if we step on a male cockroach to death. But if we trample the female cockroach to death, even if the female cockroach is trampled to death by us, the eggs in its body will not be a major problem, and it will continue to hatch in the female cockroach's body until it finally grows and takes shape.
Taking a step back, we often think that cockroaches have been trampled to death by us, but in fact, they areIt's probably just cockroaches playing dead.
Cockroach eggs have a strong protective shell, and ordinary feet cannot be stepped on. There is a high probability that the cockroach's eggs will stick to the soles of our shoes, and then continue to wait for the opportunity to hatch and take shape.
And cockroaches are conceived and ovulate for life, which also leads to the cockroach's ability to reproduce and be terrible. The larvae of cockroaches will be in the "nursery bag" of the female cockroach and may also be outside the body of the female cockroach.
Therefore, when we see a cockroach at home, it is better not to step on it. Because until you have stepped on a dead cockroach, you can barely tell if it's a female or a male cockroach.
2. Dead cockroaches will provide food nutrients for their peers and spread more bacteria
If you don't dispose of the dead cockroach, then it is very likely that it will be found by its own kind and taken home to feast on, after all, cockroaches as insects have only one nature, that is, to reproduce.
In addition to this, we also said earlier that cockroaches contain more than forty kinds of bacteria in their bodies, and if we rashly step on a dead cockroach,There are bound to be many bacteria in the cockroach's body on the floor and on the soles of our shoesIf one is not treated, it is easy to cause harm to the elderly and children with low immunity at home.
Therefore,Cockroaches can't be trampled to death. Stamping a single cockroach to death has the potential to provide a week's worth of food for its own kind, as well as spreading additional germs, with a high risk.
"Hunger strike" for a month, still alive
A researcher has done an experiment in which the American cockroach is put into the laboratory environment to interrupt the food, and only supply water for the cockroaches to drink, and after a month, the cockroaches are still able to crawl around, and even their behavioral ability is not affected in the slightest.
Not even afraid of nuclear radiation
The harm of nuclear radiation to human beings is self-evident, and if you get a little bit of it, your DNA will be affected, and sinister diseases such as cancer and leukemia will follow.
But for cockroaches, after being exposed to nuclear radiation, evenAs long as you simply shed your skin, you can completely avoid the hidden dangers caused by nuclear radiation。It's really impressive.
Cockroaches can survive when they are sent into space
Cockroaches, known as the "strongest creatures on the surface", have been sent into space to take on the important task of "exploring" space. The European Space Agency (ESA) has sent 54 cockroaches into space and equipped them with a separate space life system room. The cockroaches that went into space not only survived, but also successfully conceived and gave birth to 33 baby cockroaches. Scientists have found that these baby cockroaches not only grow faster and run faster, but also become stronger.
This is enough to show how tenacious the vitality of cockroaches is. As a cockroach, it has been in space, eaten lunar dust, and died only 9 days after taking off its head.
Children are very susceptible to being targeted by cockroaches, mainly for several reasons:
1.Infants and toddlersDelicate, blowing bombs can be broken, cockroaches like this**;
Love to sweat: Cockroaches are mainly tracked and located by the heat, carbon dioxide and odor emitted by the human body. Babies and toddlers emit more heat and sweat a lot, so they are easy targets for cockroaches.
3.Babies often drink milk on the bodyMilky scent, which is the sweet and fragrant target that cockroaches like.
Dark clothes:Cockroaches like people who wear dark clothes. If you go out and dress your baby in darker clothes, it can also be a specific target for cockroaches.
Many mothers will pay special attention to the fact that their children are bitten by cockroaches, because after the child is bitten by cockroaches, not only will the child feel very uncomfortable, but also there will be a lot of "potential harm", and serious may also threaten the baby's health.
1. Running from a neighbor's house
Cockroaches are good at drilling all kinds of crevices and holes, and these small spaces may be natural secret passages for cockroaches to enter your home.
1) Although the cleaning of the house is very good, it is impossible to close the doors and windows 24 hours a day, sometimes open the windows to breathe and so on, it is possible to get in through the cracks in the windows, if the neighbors are closer, there are cockroaches, then these cockroaches will also come out to visit.
2) Then there is the possibility of climbing up from the sewer, in fact, the sewer should be the most important way for cockroaches to enter the room, generally speaking, many people do not care, but in the sewer is often dirty, and cockroaches are also breeding in these places, because its reproductive ability is very strong, so sometimes it will crawl to the house through such a small gap or the like.
2. Those who follow the master in
Cockroaches also have a diffusion method called passive diffusion, that is, they can follow the owner into the home, such as the owner's clothes, the owner's luggage, some furniture and clothes in the process of the owner's relocation, etc., are good carriers for cockroaches to enter the room.
3. Coming in through online shopping packages
In today's society, online w shopping G has been common and popular, especially on holidays, and even young sisters and little brothers use small carts to transport express packages to their homes frequently, the name is "how hard do girls fight to get express delivery", since cockroaches can spread passively, these express packages are also common carriers for cockroaches to enter your home.
If you're "lucky" enough to encounter a cockroach at home, there are hundreds of cockroaches lining up to surprise youAfter all, cockroaches that live in groups -There is only a difference between 0 and countless quantities
You may only see oneBut out of sight, there may be a litter
Especially when the temperature is gradually warming, cockroaches are multiplying more and more like stimulants.
Bugs with the title of "Xiaoqiang" only need to mate once, and they can lay eggs continuously and uninterruptedly.
It can be said that a bug can give birth to a "company".
Corners, sinks, drawers, and other corners are their habitat.
They crawl through late at night
Water dispensers, toothbrushes, towels and even food
I believe that there should be no one in this world who will like this pest (if there is anything I didn't say).
They are more like the owners of this house than you are.
In hundreds of millions of years, there have been three mass extinction events, and the humble creature cockroach has survived the catastrophe of volcanic eruptions, meteorite impacts, and floods. Every time the ecological upheaval of the earth occurs, a large number of organisms are extinct, and only the most tenacious life can save their lives, which is nature's most cruel law of survival of the fittest.
But who would have thought that the dinosaurs that dominated the earth could not avoid the catastrophe, and the humble cockroaches became the winners who had the last laugh.
1. Be able to swim and not be afraid of water
If you catch a cockroach and flush it off the toilet, there is a high chance that it will crawl back. As mentioned earlier, cockroaches breathe through the respiratory holes in their abdomen, and at the same time, there is a layer of oil in their abdomen, which can effectively prevent water from entering the respiratory holes.
The efficient respiratory system makes it easy for them not to breathe in the outside air for a short time, which is enough to buy them time to survive.
2. The final star of the breath of the "mantis" - headless
Cockroach "blood trough".It's very long, and you can live for a week even without a head. After losing their heads, the wounds on their necks will coagulate and close, without excessive blood loss, and the blood will circulate; And they are born with mastery"Breath of the Praying Mantis"., breathing through the orifices of the joints of the body, the valves, rather than through the head and mouth; However, they do need to drink water from their mouths, so they will die of thirst after a week.
Cockroaches are indeed photophobic and afraid of people, tend to hide in corners, and reproduce quickly.
German cockroaches can reproduce for many generations a year, and a female can lay eggs after one mating, up to 400 eggs (8 egg sheaths), and it only takes at least two months for the eggs to develop from the eggs to the adults. If left unchecked, the offspring produced by a pair of German cockroaches will continue to breed, and the number of offspring will be endless, with a total of 10 million in a year.
The progress of the American cockroach is slower, reproducing one generation a year, and a female can lay up to 800 eggs (16 egg sheaths) a year, and it takes about a year for the eggs to develop from the eggs to the adult.
If you want to live a decent life, don't think about these Schrödinger's cockroachesIf you don't see it, you just don't see it.
If you see someone saying that cockroaches will bite, don't rush to move yet.
Cockroaches come out to bite people at night, it is a small probability event, there are so many delicious foods at home, and there is not much demand for biting.
Cockroaches prefer small babies over older babies over their 300-month-old babies, because their hair and nails are soft, and the milk stains and other food debris left around their mouths before bed are more likely to attract cockroaches.
If you are really bitten, don't panic, the cockroach itself is not poisonous, and there is usually no major problem after being bitten except for some redness and swelling. However, some people will be hypersensitive to the secretions of cockroaches and the proteins in the feces, causing a more serious allergic reaction.
What if you get bitten by a cockroach at home?
Allergies to cockroaches, on the one hand, it is necessary to minimize the chance of contact with cockroaches, and on the other hand, you can use the drug ** allergy under the guidance of a doctor. Cockroaches prefer warm, humid and food-rich places, so they should open windows frequently to ventilate and maintain indoor air circulation. Also clean the room to avoid the residue of snack residue as much as possible. Always keep food in an airtight storage box to avoid cockroaches.
After contact with cockroaches, an allergic reaction occurred, accompanied by symptoms of itching and redness, and drugs such as calamine lotion, compound menthol ointment, and tacrolimus ointment can usually be applied locally according to the doctor's instructions to relieve the symptoms.
If cockroach allergies are more severe, antihistamines can also be used**, such as cetirizine hydrochloride capsules, midazostine sustained-release tablets, loratadine tablets, etc., which have direct anti-allergic effects and help eliminate symptoms caused by allergies.
Cockroaches are social insects, and if a cockroach comes to your home and finds a warm and humid place to live, they will send a message to find their companions to live with.
Cockroaches generally disappear from people's vision during the day, and at night they sneak out to look for food and water everywhere at home. That is to say, if cockroaches are found during the day, it can indicate that there are more cockroaches at home.
As for whether there are hundreds of thousands of cockroaches, it depends on how long the cockroaches have lived in your house.
The egg sheath of a female cockroach can hatch a dozen to dozens of small cockroaches, and the egg sheath is like a nursery barn, no matter where it is stuck or carried around by the female cockroach, it will not affect the hatching of the eggs inside.
The female cockroach of the German cockroach can carry the egg sheath until hatching, which can also be said to be "raw" while walking.
As the saying goes, you can't step on cockroaches with your feet, that is, because the female cockroach carries an egg sheath on its tail, and a step on it will make the small cockroaches inside break out of their shells in advance. This is just a hassle for the little cockroaches.
Nausea also carries a variety of germs.
Xiaoqiang, who "can't be killed".Definitely a nightmare for countless people.
Terrible,The higher the temperature, the faster the cockroaches will reproduce!!
When it comes to exterminating cockroaches, I'm angry! I have tried all kinds of methods, but there are still traces of cockroaches in the house.
But in fact, many people get rid of cockroaches in the wrong way!
1. Of course, some people will choose to use itPesticidesto eliminate cockroaches, but there are many kinds of insecticides on the market, and different agents have different effects on cockroaches, and different varieties of cockroaches have different reactions to the agents, so it is best to choose a special agent to kill cockroaches, and the effect will be much better.
2. Cockroaches can easily come to the house from the outside, even if the cockroaches at home are wiped out, but if the cockroaches in the neighbor's house still exist, they will easily invade the house, so that no matter how to eliminate cockroaches at home, there will be cockroaches outside that continue to come in, and naturally they will not be clean.
3. Mothballs are a common insect repellent product, and the main ingredient is camphor. Camphor has a strong volatile odorIt has a repellent effect on cockroaches and other pests. It is often used in places where cockroaches are infested to keep cockroaches away by volatile odors.
However, mothballs usually have a small range of effect and are not very effective in completely eliminating cockroaches, mainly in the area where mothballs are placed. Cockroaches may avoid this area, thoughCockroaches have a strong vitality and reproductive ability, they can survive and reproduce elsewhere and thus continue to be a problem.
Moreover, cockroaches have strong adaptability, and after long-term exposure to mothballs, they may gradually become resistant to the smell of camphor and continue to move nearby.
In addition to having no effect on cockroaches, mothballs are quite harmful to people.
The main component in mothballs is highly volatile. When people put on clothes where mothballs have been placed, this substance can enter the bloodstream through **.
If there is a newborn at home, do not use it, the impact on the newborn is very greatWhen a newborn wears clothes that have been stored with mothballs, it will bring greater physical harm to the child.
Since mothballs are useless to cockroaches, and they are so harmful to people, there is no need for us to use them, and we must not use them for babies at home.
In short, if you want to kill cockroaches, you must choose the right method to avoid misunderstandings!
There are nine ** don't know, in fact, cockroaches are most afraid of the smell of camphor trees!
