    Cockroaches end up starving to death.

    Cockroaches have no head and can still survive for a week. If you understand why cockroaches and some other insects can survive without heads, you can understand why humans can't. If a human is decapitated, it will immediately bleed, lower blood pressure, hinder the transmission of oxygen and nutrients, and cannot give the tissues needed to sustain life.

    In addition, human breathing depends on the mouth or nose, and the brain controls these functions, so if you cut off your head, your breathing will stop. In addition, humans cannot eat without a head. But cockroaches don't blood pressure in the same way as humans.

    Cockroaches don't have the same large vascular network as humans, and they don't need high blood pressure to ensure that blood reaches the capillaries. They have an open-ended circulatory system that doesn't require high blood pressure. When you cut off their heads, the wounds on their necks will clot quickly due to the action of platelets, so that they don't stop bleeding.

    Moreover, cockroaches breathe through the valves – they have small holes in each segment of their body. Plus they don't need to go through the brain to control respiratory function, and the blood doesn't need to transport oxygen. They only need to pass through the valve duct to breathe air directly through the duct.

    Cockroaches are cold-blooded, which means they require much less food than humans. In other words, they can last for weeks with a single meal. As long as they don't encounter predators and their wounds aren't infected by bacteria or viruses, they can survive.

    Hello dear cockroaches can't be eliminated because they reproduce very fast An adult cockroach can produce an egg containing 14 to 40 eggs every 7 to 10 days, and then incubate it in about a month, if the temperature of the incubation environment is higher, the shorter the time required. Sprinkle a thin layer of laundry detergent on the place where cockroaches often appear, which can play an effective role in eliminating cockroaches. Because the laundry detergent is alkaline, and the surface of the cockroach is acidic, and the cockroach's abdomen will have several small holes for breathing

    Because the head of the cockroach plays little role in maintaining survival.

    When a cockroach loses its head, it does not die immediately, but will survive for a period of time, the reason is that the cockroach's body structure is relatively special, its respiratory organs are not in the head, but in the abdomen, so losing the head has no effect on the cockroach's breathing at all.

    Then the cockroach's blood circulation system will work, because the cockroach's blood circulation belongs to the open tube, then in the case of losing the head, the cockroach's sac blood cells and other surrounding cells will quickly block the wound, and the cockroach can continue to survive for a long time in this situation.

    <> cockroaches can be killed directly. Cockroaches are one of the most germ-carrying pests, so avoid using your hands when fighting cockroaches, and choose fly swatters, shoes, or other items. After the killing, the corpse of the cockroach should be cleaned up in time and the items of the cockroach should be swatted.

    The adults are dead and the eggs are still alive, so the best way to wrap them in paper and take them outside and burn them with fire.

    Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households. Warmth and love tide is an important habit of cockroaches.

    It is not difficult to find that whether it is in a restaurant, a home, a train or a ship, the kitchen is always the most invasive. Even in the kitchen, they generally like to live near stoves and sinks. Like the dark and afraid of light, day and night, this is also an important habit of cockroaches.
