When you find cockroaches, they are all facing the sky, are they dead or alive?

I'm dying, but I'm not completely dead.

Solution: Make up for it and sweep it away with a broom.

Room: Cockroaches can shrink their bones, and they can shrink their bodies to a flat scale, and then burrow through the cracks in doors and windows.

Solution, sprinkle more cockroach medicine on the corner.

If you were told that I turned it over, would you believe it? Or maybe the calves can't hold up, can you believe it? In fact, most insects will reverse their bodies when they die, which is related to the law of gravity and inertia.

Insects generally have six legs, which are distributed on both sides of the body, and three pairs of legs are symmetrical to support the entire body. When the insect is going to die, the feet also lose their strength when they are in it.

1. When two feet vibrate, tilt, or fall, the whole insect loses its center of gravity, and gravity will cause it to fall and turn sideways; As the rest of the feet are scratched outward, the weight of the abdomen and back causes the insect to roll. When the insect's abdomen is facing the sky, its feet can only vibrate into the air, and it can't grasp the fulcrum and can't support its body, so it is difficult for it to turn over again.

Because the cockroach's stomata are in the abdomen, and cockroaches breathe through the stomata in the abdomen, the insecticide oil will cover the cockroach's stomata so that the cockroach cannot breathe until it dies. It's the same as when a person is about to suffocate in the water, he struggles to swim out of the water to get more air. If you use detergents such as dishwashing detergent or soapy water, you can also kill cockroaches.

Therefore, cockroaches are not afraid of pesticides, but the stomata will be blocked, causing cockroaches to suffocate to death. There is another saying that the back of the cockroach is harder and heavier, which is used to protect the place, and the abdomen is more fragile, although it is relatively light, when the cockroach dies, the whole hand and foot will be struggling, the body will continue to move around, and finally because of the heavy back and light belly, and the center of gravity will be unstable will turn over, not only cockroaches, but also the vast majority of insects. In fact, not only cockroaches, but also fish, birds, and other beetles, most of them are facing down when they die, of course, it is not absolute, and some will also have their abdomen downward due to the terrain or special actions before death, but it is just rare.

The first statement:

1. The body arrangement of most animals is protective or bone on the back, and the muscles and other fragile tissues are on the ventral surface, so the back is heavy and the belly is light.

Second, the protective surface (back) is streamlined in order to be strong, and the shape of the supporting surface (foot) is irregular.

3. Animals are mostly the most vulnerable before they die, so the muscles are weak to support the heavier dorsal tissues, and before they die, their backs fall to the ground due to gravity.

Fourth, some animals land on their backs due to accidents, and the strength of their muscles is not enough to turn over, and they will die after too long.

It could be natural death and drug poisoning.

Most of them look similar, but a closer look reveals the difference. Current taxonomists classify cockroaches into about 6,000 species, of which about 50 are pests.

For example, the commonly known Asian cockroach. In addition, the American cockroach (American cockroach.

German cockroach (German cockroach.

Brown cockroaches and Australian.

Cockroaches are also widely distributed.

One of the characteristics of the cockroach life history is the long cycle. In the case of the German cockroach with the shortest cycle, it generally takes more than 2 months to complete a generation, and the longest American cockroach takes more than 1 year. The length of life history varies not only from species to species, but also with different conditions such as temperature, nutrition, etc.

The adult worm also has a long lifespan, the shortest German cockroach is about 100 days, and the longest-lived American cockroach can survive for up to 1 year. The length of life also varies depending on the type and environmental conditions.

Cockroaches have a long life cycle and they also have a long lifespan. Therefore, a fertilized female cockroach produces a large number of egg sheaths in her lifetime, and the American cockroach can produce more than 50 at most, so the cockroach is very fecund.

With the exception of cockroaches, many insects die with their abdomen facing up. The feet of the cockroach itself are contracted under the body at ordinary times, so as to form a relatively large chassis, which is conducive to the downward movement of the center of gravity, and the feet of the cockroach are dry after death, because the angle of extension of the ligament contraction will be relatively large, that is, it will stretch relatively straight, which directly leads to the center of gravity in the upper part of the entire façade, which is the reason why it is easier for the cockroach to turn over after death, and the reason why it is not easy to turn back after turning over is because the back of the cockroach is semi-arc, no matter which direction the force pushes, will produce an opposite corresponding stress, the magnitude of this force is proportional to the magnitude of the propulsive force, and the semi-arc structure is also conducive to the smooth over-smoothing of the object on the surface of the object when it is pushed by the propulsive force, and it is not easy to produce resistance to cause rollover———.

Cockroaches do not come out during the day, because cockroaches are nocturnal creatures and have a certain sensitivity to light. During the day, when the light is strong, the cockroach's eyesight and reflexes will be affected, so it will not run out during the day. If you find cockroaches during the day, it means that there are many cockroaches in your home and need to be cleaned.

The cockroach is a nocturnal creature, so it generally does not run out during the day, because it is afraid of light, so it does not like to stay in a place with very bright light.

The eyes of the cockroach are in the darker the light, the clearer it can see, and when the light is strong, the cockroach's vision and reflexes will be affected, so it will not go out during the day.

If you find that there are cockroaches running in your home during the day, it means that there may be a lot of cockroaches hiding in your home and you need to clean your home, otherwise there will be a lot of cockroaches at night.

No. Cockroaches like darkness and are afraid of light, and generally cockroaches rarely come out to move during the day, and they only come out to move after turning off the lights at night. Cockroaches are nocturnal insects, and this is because of their adaptation to the human environment.

If cockroaches can be seen during the day, especially in places where there is no food, then it can be judged that the degree of cockroach infestation in the area is very serious, which can also be used as a basis for cockroaches to judge the degree of harm.

The activity of cockroaches is affected by temperature. When the temperature is lower than 15, the cockroach is inactive or slightly moving, if the temperature is around 4, the cockroach can not be active, when the cockroach is lower than 5, the cockroach will die quickly; When the temperature is 15 37, the activity of cockroaches also increases with the increase of temperature. When the temperature is above 37, the cockroach will be in a state of excitement; When the temperature is above 50, the cockroach dies. When the temperature is too high or too low, it will cause the death of cockroaches.

No, cockroaches are nocturnal and hide in dark and hidden places during the day; There are four activities at night, with a peak activity from 9 p.m. to 2 p.m.

Most species of cockroaches inhabit the wild, and only a few species inhabit. The latter has a close relationship with humans. These species especially prefer to inhabit places where the room is warm and close to food and moisture, such as kitchen cupboards, pantries in canteens, crevices in stove walls, etc., and in sewer trenches.

Introducing Cockroaches are one of the oldest insects on the planet and once lived in the same era as dinosaurs. According to fossil evidence, primitive cockroaches appeared on Earth about 400 million years ago in the Silurian period. The fossils of cockroaches that we find or the cockroaches we find in coal and amber are not much different from those found in the cupboards.

Its appearance has not changed much over the centuries, but its vitality and adaptability have become more and more tenacious, and it has multiplied to this day, widely distributed in all corners of the world. It is worth mentioning that a decapitated cockroach can live for 9 days, and the cause of death after 9 days is excessive hunger.

We probably all understand a truth, whether it is humans, animals or various plants, the moment they are born, they should understand that they are about to face death or extinction ......That's the law of nature! Therefore, both animals, plants and humans will face death, but the death of some animals is very strange. For example, when a cockroach turns over after death, some people will think that this way of dying seems a little weird, so why is the cockroach the other way around after death?

Let's take a look at what causes it!

In fact, not only cockroaches are six feet in the sky after death.

Many other insects, like cockroaches, will turn their feet into the sky when they die. Because many insects have six legs, when they are about to die, their nervous system.

They will lose their coordination, and they will not be able to control their six feet. Coupled with their constant struggle before they died, they turned their abdomen over and turned their feet to the sky. However when those have a curved back shell.

When the insects are on their feet in the air, their feet can't catch anything, so at this time, it is difficult for their feet to flip to the ground. These reasons explain why cockroaches turn to the sky on their feet after death.

We all know that cockroaches are the most annoying animals in the family, because where he is in a dirty place, there are a lot of bacteria on his body, and his place proves that the place is not very clean, many people feel very distressed about this, in order to deal with cockroaches, they also come up with a lot of medicine to deal with cockroaches. In fact, we can all deeply feel that especially in rural areas, as long as we go to the streets in a long time, we will hear people's radio shouting cockroach medicine everywhere.

Rat poison ......It can be seen that there may be more cockroaches in rural areas. So what else do you know that causes insects like cockroaches to turn over after death? Feel free to leave your answers in the comment section!

Cockroaches have a hard back and a high center of gravity, so it is difficult to maintain their abdomen all the way down, and it is easy to roll over, and when their own strength is insufficient, it is very likely that they will not be able to turn back normally, and eventually lead to starvation and thirst to death.

Because when they are about to die, the nervous system will be unable to coordinate and not be able to control their 6 feet well, and they breathe on the abdomen, and it is difficult to turn them back when they turn them over.

Because they breathe on their abdomen, they turn over and let themselves breathe as much as they can, and they die before they can breathe.

Because they breathe on their stomachs, they roll over and let themselves breathe as much as they can and then die without breathing.
