Chapter 379

As soon as Shi Xiaorui finished, there was a cockroach in front of her. She was not afraid of people's climbing.

Shi Xiaorui resisted the impulse to step on it, because if this is a female cockroach, one foot can't kill the eggs in her stomach, and soon more small cockroaches will emerge, so she can only watch it swagger away.

Lao Huang saw the cockroach in Shi Xiaorui's eyes. He was obviously used to cockroaches at home. He just stepped on it and squashed it.

Shi Xiaorui is not in a hurry to stop him. He sees the cockroach being trampled and burst out. He doesn't know what it is.

She should have thought that if the house is dark, damp and not clean, cockroaches are indispensable!

Shi Xiaorui dislike make complaints about cockroaches. Dislike, she never saw live cockroaches before she went to school. Most of them read pictures on the Internet, and how annoying and difficult to destroy such small creatures as Tucao.

At that time, Shi Xiaorui missed this post. Because the building owner wrote it with great humor, he unconsciously read it and remembered many effective ways to eliminate cockroaches.

Later, she finally faced cockroaches in her life, and proved that the method of enthusiasts in that post was really good.

Shi Xiaorui originally wanted to recommend a kind of spider that included cockroaches in the hunting range. If she kept it at home, as long as there were enough spiders, the cockroaches would be eaten up slowly. But just as she was about to open her mouth, a chicken was walking near the body of the cockroach. When she saw the flattened cockroach, she immediately rushed over and ate it with a quick and fierce bite.

All that remained on the ground was the unknown half liquid.

Shi Xiaorui gave up the idea of recommending spiders to Lao Huang. Seeing the chicken's quick and skillful action, I think it's better to forget it, so that the spider and cockroach will not be eaten by the chicken.

Shi Xiaorui told Lao Huang simply from the habits of cockroaches: "you see, if there are cockroaches at home, it means that the environment is dark and humid, which is suitable for the growth of cockroaches. That's why there are cockroaches at home. Moreover, cockroaches carry a lot of germs. If cockroaches crawl over the food and people eat the food, it's easy to cause food poisoning, If it's serious, you'll be infected with hepatitis, pneumonia and many other kinds of diseases

Shi Xiaorui said, can't help pausing for a while, old Huang's wife got pneumonia, should not be spread by these cockroaches, right?

Lao Huang thought of it all at once. He looked at the little insects he had never cared about before and asked in disbelief: "because of them, did the child get pneumonia?"

"It's not sure, but cockroaches do have the potential to spread pneumonia," Shi said

Lao Huang looks like he can't wait to tear the cockroaches to pieces. He lifts a straw mat next to him. Unexpectedly, there are seven or eight cockroaches hiding below. Suddenly, they are exposed to the sun from the dark. The cockroaches react quickly and want to escape to other corners nearby.

Can Lao Huang make them run away? He stomped his feet. Except two of them ran fast, the others were crushed.

Shi Xiaorui can only persuade him: "it's not enough to trample on these insects. Their vitality is very strong. Some cockroach eggs can hatch even if they are squashed. Moreover, if one cockroach is found at home, there are at least 100 of them. It's useless for you to trample on one or two. Their number will recover soon."

Lao Huang looked at these cockroaches and thought that they were dead. Although he knew that this kind of insect was difficult to deal with, he never racked his brains to eliminate them. He never knew that it was so difficult to drive them away completely.

Don't mention the ancients. For modern people who have so many ways to choose, the ways to eliminate cockroaches are constantly advancing with the times, because cockroaches are a kind of insect that evolves very quickly. No matter how effective insecticides are invented by human beings, they will soon evolve antibodies, making this insecticide ineffective, We have to use a new insecticide after a period of time to prevent cockroaches at home from developing drug resistance.

Not only cockroaches, but many of our common insects can spread diseases.

Needless to say, flies often dock on rotten things and are easy to be infected with bacteria. However, many people do not know that mosquitoes can also infect a variety of diseases, including malaria. Think about the fact that life is full of so many unstable factors. When Shi Xiaorui studied all kinds of infectious insects, she just wanted to develop some preparations, which would destroy them all at once.

Unfortunately, it's just an obvious whimsical idea. What Shi Xiaorui can do is to strengthen her own resistance.

For example, there are still patients with weak health in Lao Huang's family, so we can't use insecticides and other highly toxic means of killing insects. At present, we can only try our best to reduce the damp and dark corners of the house, often clean the house to keep it clean, and do some things like cockroach house to kill cockroaches.

Although the effect is slow, the victory lies in safety and can be maintained for a longer time.

Shi Xiaorui gave Lao Huang some ideas about how to make his home a place where cockroaches can't live and how to make them move as soon as possible. Niu Er also studied hard.

There's no way. Nowadays, people's health awareness is not very strong. Most people have cockroaches in their homes, but they never realize the greater harm of cockroaches.

Now I know. No matter whether you have the energy to do it or not, the way to drive cockroaches is to learn first. What if you use it one day?

Shi Xiaorui introduced to them several effective ways to kill cockroaches that she still had an impression of. Under the leadership of Niu Er, she bid farewell to Lao Huang and went to the next one.

The situation of this family is more difficult than that of the previous one. It can be seen from the dilapidated degree of the house. Even the door is dilapidated and barely stands inside the door frame. I feel that with a little more strength, I can tear it down directly.

Niu Er didn't knock on the door at all. He yelled at the top of his voice: "Lao Liu! Open the door

This time, the speed of opening the door is slower. Shi Xiaorui is not right to listen to the sound of walking. It's heavy and light.

When the door opened, just saw a gray haired man, limping back a few steps, let them in.

Out of professional habits, Shi Xiaorui first looked at the man's legs.

His legs are still good, that is to say, when he reaches the ankle, he has an obvious curve of turning outward. His disability is very obvious, and there is no way to hide it.
