"Ho ho", a cockroach was trampled to death, but found that the cockroach did not die, but could not crawl, maybe some cockroaches will not crawl and then die silently, but in fact this is not the case.
The cockroach is really dead, but the cockroach is not crushed, not to mention that it will stink, and the corpses of many cockroaches can become the energy source of this cockroach, and this cockroach can be resurrected.
Why do we often see cockroaches that are trampled to death, but later we find that there are so many cockroaches?
If you see a cockroach and you step on it and it dies, but after a while you see another one, it's because they came in groups.
There are a lot of cockroach egg sheaths in the air, and as long as you can find a place where you can hatch, there will be a large number of cockroaches.
So are cockroaches really so tenacious?
The vitality and reproductive ability of cockroaches.
In fact, the vitality and reproductive ability of cockroaches are really very strong, not only can they survive against everything, but also can give birth to a large number of larvae in a relatively unfavorable environment.
The first is the diet of cockroaches, which are hunger-tolerant animals that are able to survive for a month without eating or drinking.
Cockroaches are not picky eaters, as long as they can chew and swallow anything can become food for cockroaches.
Their "recipes" include all sorts of plant scraps, carrion, and even human dandruff, which become their food, and they can live forever as long as they have them.
The second is the reproductive ability of cockroaches, and the reason why cockroaches survive so tenaciously is that their reproductive ability is too strong.
Cockroaches can lay multiple egg sheaths at a time, and there are multiple small cockroaches in this egg sheath.
For example, the German cockroach can lay 10 million offspring in a year, which is a very large number, and cockroaches only need females to mate once or twice, and can produce eggs for life, and do not need to mate with males once every time.
As long as the baby cockroach hatches in the body of the female cockroach, and then slowly crawls out on the ground, it can slowly grow up and become a female cockroach with reproductive ability.
If you just want a small cockroach, you can also raise a few to see, I wonder if you can raise a group of cockroaches from a small cockroach?
In addition, if you want to kill cockroaches all day long, you might as well find a way to make money with this, the insect farm is a big business that can make money, there are a large number of cockroaches in life and destroy the people, why not lay eggs and breed these cockroaches, and then sell them everywhere?
So why are cockroaches so vigorous?
This is because their egg sheath has a layer of glue on the outside, this layer of glue is like a shell, we usually wipe the floor when cleaning, the egg sheath will stick to the floor, at this time it is not easy to dry, blocking the air circulation of the egg sheath, and the egg sheath itself is relatively hard.
So this will lead to some of the egg sheaths being wiped off when we clean again, but some of them will remain on the floor, and these egg sheaths may become dry and then very hard due to lack of circulation.
But it can't stop it from hatching at a faster rate, so even if a small part of the egg sheath is not cleaned, it will be dry, but it will allow the cockroach to slowly hatch out of the egg, which will lead to the elimination of the mother after the baby cockroach will also run rampant.
In order to keep the life of cockroaches on the earth, people have tried to get rid of cockroaches but have never been eliminated, so people have thought of many methods, one of which is to spray insecticides.
Does spraying insecticides work for cockroaches?
Many people use this method to kill cockroaches in their homes, but the effect is not very obvious, this is because the vitality of cockroaches is too strong, even if a certain number are killed, but their family is still alive in the air, as long as there are conditions, their family will be revived.
And the effect of spraying insecticide has certain limitations, that is, if spraying insecticide can spray small cockroaches, then this method is still more effective, but in many cases people can not spray small cockroaches, because generally small cockroaches like to live in the dark, so it is difficult for people to find, it is difficult to spray.
People can spray insecticide when they go home very late, and then they can see a lot of small cockroaches when they look in the mirror or turn on the light, and then they can sprinkle insecticide.
Another reason for spraying insecticides is that cockroaches are prone to drug resistance, when the bacteria on the cockroach have the ability to resist spraying insecticides, spraying insecticides will become ineffective, just like people drink medicine, and they will develop resistance after drinking for a long time.
There is also a way to kill cockroach bait, it by tempting cockroaches to eat, and then slowly die, the death effect of this method is a little better than spraying insecticides, but it is not very effective, and the cockroaches kill more after the bacteria in the body will become more and more resistant to the drug, which will reduce the efficacy.
Therefore, even if it is a relatively effective method of killing cockroach bait, it is also precious, and there is a way to control the water source, although the cockroach can starve for a month, but can not not drink water for a long time, if the ground at home remains dry, the cockroach will not drink and gradually decrease.
However, some people put a little water source in their home, such as a cruet and the like, so that the cockroaches will always have water to drink and will not die because of the lack of water.
So in order to kill cockroaches, it is useless to control the food alone, but also to control the water source.
Why cockroaches can't be trampled to death.
When the cockroach lies on the ground, it has six feet, so that it is not easy for the foot to be trampled to death, so why is the cockroach so small, why can it clamp our big feet and not be crushed to death?
This is because the shell of cockroaches is very hard, they have a shell on the surface of their body, and there is a soft membrane near the skin of the body, and the combination of these two layers forms the shell of the cockroach, which is more difficult to break even if you step on it with a big foot.
Many people step on cockroaches for fear of their stink, and often step on dead cockroaches, which will also allow excess cockroaches to take the opportunity to escape, but most of them will still be discovered, so cockroaches will become more and more bold and dare to run everywhere.
The tail of the cockroach can also pierce the skin of the person, and the tail of the cockroach will be parasitic with nematodes, this nematode will hide around the tail, once the nematode feels that the surrounding environment is unsafe, it will climb on the tail of the cockroach and escape with the cockroach, so the cockroach is generally "more than lucky", and will eventually be discovered.
