Cockroaches, as one of the most hated creatures of humans, actually came from 2The Triassic period, 3.5 billion years ago, was essentially the same age as the dinosaurs and belonged to one of the oldest insects on Earth.
And the ability of cockroaches to transmit diseases has existed since ancient times, but it is not as intuitive as the harm of rats, mosquitoes, etc., but we must not be carelessThe harm that cockroaches bring to us.
However, if there are children at home, you must not see cockroaches and then simply trample them to death!
This is not a special caseIf you don't know how to fight cockroaches, you may be hit at any time!
Not long ago, the neighbor Xiao Li's child was fine at home, but suddenly had a high fever of 40 degrees, cough and abdominal pain, Xiao Li and her husband died in a hurry, and hurriedly took the child to the hospital.
Pneumonia?Tuberculosis?Various tests have been done, but none of them have been.
But it's just a high fever that doesn't go away, what's going on?
In the end, I was really inconclusive, so I went to the chest CT.
I saw that there were oval worms in the child's lungs, and the flagella at one end of the worm kept swinging ......
Oh my God, why are there worms in the lungs?What kind of worm is it?
Still alive ......
I didn't have time to guess, so I finally hurried to the ventilator to assist and fight infection at the same time**.
Confirmed results:These insects turned out to be related to cockroaches.
The worm that appears in this lung is calledTrichomoniasis cockroach infection.
This cockroach trichomoniasis was originally parasitic in the intestines of cockroaches, when the cockroach was swatted to death, the cockroach trichomoniasis eggs entered the air, the child always sat on the ground to play, on the ground hands and feet at the same time, the worm was sucked into the lungs, eaten into the mouth ......
That is, if in front of the child, youPedalDead cockroaches, eggs may enter the airborne into the lungs!
First of all, we must know that cockroaches carry more than 40 kinds of bacteria that cause disease and poisoning, and can transmit leprosy, plague, dysentery, typhoid fever, pediatric diarrhea and a variety of parasitic diseases. These common diseases in life are caused by bacteria on cockroaches
Cockroaches also contain Salmonella bacteria on their bodies, which can easily cause us to suffer from gastroenteritis and even food poisoning
The bacteria carried on the cockroach's body can easily enter our body through the food it crawls on, endangering our health!
If you want to kill cockroaches, you should first think about how to create an environment that cockroaches don't like, everyone knows that cockroaches like dark and damp places, as long as the environment is ok and there is food to eat, it will not leave, so I don't want cockroaches to become roommates, the first thing is to clean the environment, garbage should be cleaned up in time, and the food will not be exposed, or put it in a sealed jar or put it in the refrigerator, just don't let cockroaches have a chance!
And people who live in apartment complexes may also react, even if they clean their homes, they are still easy to see cockroaches, what is going on?That's because cockroaches will scurry around with the water pipes of the building, and if they happen to have something to eat when they come to your house, they will settle here with their families, so in addition to keeping the environment clean and tidy, it is best to close the lid of the kitchen sink and the bathroom drain hole before going to bed to reduce the visit of cockroaches.
1. The genome of cockroachesStronger than most insects
New research shows that cockroaches' genomes are the most powerful of all the insects studied, and it's these super-strong genes that make them masters of survival on Earth.
Taking the genes related to chemosensing as an example, the American cockroach has 154 olfactory receptors and 544 taste receptors, which is more than any other insect on the planet, which means that they can find and distinguish food more sensitively than other insects.
2. Not picky eaters at allThe variety of diets is ridiculously rich
Although cockroaches are also like humans, they love cheese, meat and sugar.
But they also don't reject cardboard, bound books, human toenails, or even rotting meat, blood, or feces.
Even more terrifying is that they have been found to eat their own species, such as other dead or mutilated cockroaches, which has the advantage that they can find food anywhere.
3. They dare to eat anythingThanks to powerful detoxification genes
They are not afraid of poisonous things for many animals, because a gene called cytochrome P450 can help resist toxic substances, such as peppermint will have a paralyzing effect on some animals, and this gene can decompose this toxin, so cockroaches can eat mint without scruples.
They also have:Strong immune system, can find and kill pests and fungi, so they are not afraid of dirty environments and even quite enjoyable.
This is discussed on a case-by-case basis.
Small cockroaches (German cockroaches).Photophobic, group-living, sensitive to temperature and humidity, will not move easily, generally passively migrate, will enter high-rise housing through the courier box taken by the family, the packing box of large items, etc.
Cockroach (American cockroach).Able to fly, has the ability to actively migrate, but can only invade low-rise residences.
Active incursionsIt is very likely that they came from the neighbor's house next door, and there are too many cockroaches in the house to live, so the living area has been extended to the next house.
Cockroaches can enter your home through sewer pipes, doors and windows, gaps in walls, and air conditioning ducts.
If you want to stop cockroaches, you must strengthen the screen windows, plug the holes and gaps in the walls, and cover the screen at the floor drain and drain.
Passive incursionIt is the cockroaches that hide in cardboard boxes or furniture, passively move to the house, start their new life, and are sent to **, just survive.
When shopping for groceries or moving, it is easy to bring cockroaches into the house if you are not careful, and then it will flood in just a week. Therefore, every time you enter and leave the room, it is necessary to carefully check the items you are carrying at the entrance.
There are also situations that are difficult to prevent, such as when buying a courier, there are cockroach eggs hidden in the carton, and if you don't deal with it in time, it is easy to hatch, and you will soon find that your home is occupied by cockroaches.
The eggs of cockroaches are the size of soybeans and are black or dark brown. If it is empty, it is already hatching, and the bottom of the egg sheath that is incubating will produce white transparent cockroach larvaeOnce found, it should be burned to death by fire or boiling water to prevent hatching.
It is difficult to find them if they are not serious in the early stage, because they are afraid of people and light, and generally do not come out to move during the day, if you can also see cockroaches during the day, it means that it is more serious.
When cockroaches enter the home, they will first move in the kitchen area, because the kitchen has more abundant food and water.
As kitchens become denser, the cockroach family spreads to other areasThe general order is: kitchen » bathroom " living room " bedroom ".The number of cockroaches in each room is generally distributed in this order.
One. The low temperature outdoors in the northern winter is not suitable for cockroaches
As we all know, cockroaches are a class of creatures with extremely tenacious vitality and adaptability.
However, cockroaches are also limited in their ability to adapt, and their survival and reproduction also depend on suitable environmental conditions such as temperature, moisture, food, etc.
The temperature range for cockroaches to be active is 10 to 50 degrees CelsiusIf it is below 0 degrees or above 60 degrees for a long time, the cockroach will die。Since winter in northern regions is usually below 0 degrees Celsius, the low temperatures in the outdoor environment form a barrier to prevent the spread of cockroaches.
Two. Heating in the northern winter allows cockroaches to survive indoors
Although the temperature in the north is very low in winter, it is not suitable for cockroaches to survive, but due toHeating in the northWith a relatively high indoor temperature, cockroaches can still make waves indoors in the north in winter.
Cockroach adults, nymphs, and egg sheaths can survive the winter in indoor conditions. Cockroaches will gather in heated rooms** to live and breed。When the temperature rises the following year, cockroaches that are dormant indoors can spread further and set up camp in more buildings.

Three. Transportation and logistics have caused cockroaches to migrate north
In addition, the underdeveloped logistics and transportation in the previous era also brought obstacles to the migration of cockroaches. In recent yearsThe popularity of logistics has greatly facilitated the pace of cockroaches going north。With express parcels, goods, vehicles, cockroaches all the way north, the footprint has reached as far as the northeast.
The good news, though,Winter is a good time to eradicate cockroaches once and for all。Although winter is not the active season for cockroaches, and the sensory perception of cockroach damage is not serious, it is easy to achieve twice the result with half the effort in winter PCO extermination operations. Why?
Because winter is a time when cockroach populations are more vulnerable
Cockroaches are inactive in winter, have a smaller range, have a slightly lower population density than during the breeding season, and are usually highly concentrated in small, warm indoor areas, such as heating, small appliances, electronic devices, and other things that can dissipate heat.
It is easier to sanitize completely in winterIt can prevent cockroaches from spending the winter indoors in restaurants, hospitals, hotels, schools, homes, etc., and can also play a certain role in inhibiting the spread of cockroaches in the cityCockroach outbreaks can be prevented in advance in the following summer
1. Spreading diseases
Because cockroaches are widely distributed and consumed, it is easy to spread diseases by eating food. Studies have shown that cockroaches can transmit pneumonitis, melioidosis, diphtheria and other bacteria, which are extremely harmful to people
At the same time, cockroaches can also carry roundworms, insects and other eggs through contact with various germs, because cockroaches often visit various unhygienic places, therefore, such as candida spinosa, short hymenous tapeworm and other nematodes tend to attach to cockroaches and infestation to other places.
At the same time, cockroaches can excrete poliovirus and so on by sucking various viruses and bringing these viruses to other places for excretion.
2. Carry a true jun
Cockroaches carry pathogens through contact with and consumption of various germs. Cockroaches can only carry the fungus through their bodies, but they do not reproduce the fungus themselves, so it is an indirect infection, and the damage to the environment is limited.
However, cockroaches often visit garbage dumps, toilets, bathrooms, kitchens, and other places, so the spread of the virus to households is also serious.
3. Damage to equipment
Since cockroaches often gnaw on factory products, commercial foods, as well as household foods, they can cause contamination and damage to many products, resulting in economic losses. Cockroaches also often get into computers and other instruments with holes, causing computers and other equipment to malfunction.
The corner you don't pay attention to happens to be its paradise.
At home, we will often find that Xiaoqiang is like a flash, from time to time I don't know where to come from, flash, I don't know if I want to go back, flash and disappear, I can't catch it.
Finally caught its life, and a new one popped up, annoying!
Today, I will reveal to you the 4 nests that Xiaoqiang's family loves to occupy, understand clearly, and find an opportunity to destroy Xiaoqiang's nest!
The 4 places are places that everyone usually doesn't pay attention to, dark and damp and difficult to clean, but they have just become a paradise for the Xiaoqiang family to survive and reproduce.
Nest 1: Under the kitchen sink
Wet, shady, and invisible to humans, walking on the sink in the middle of the night and picking up some fish that slipped through the net is simply a feng shui treasure where the Xiaoqiang family lives.
During the big cleaning, you can definitely see the sticky matter on the water pipe under the sink, which is the excrement and vomit that Xiaoqiang vomited while eating and pulling.
Nest 2: Bathroom sewer
The wettest place for the whole family, the sewer, exhaust vent, and cabinet dark place in the bathroom are all excellent places for the Xiaoqiang family to hide, especially the sewer.
When you see a small strong man crawling out of the sewer, don't just rush it down to finish the job, its strong desire to survive will force it to force it on the inner wall of the sewer, and after the water stops, it will soon crawl out again.
Nest 3: The recess behind the refrigerator, microwave oven, TV, and washing machine
When the host is working, it generates heat and warms the whole body, which is the warmth and love that humans give them.
The kitchen appliances are their five-star hotels, warm, and there is food and drink.
One day you find that the working temperature of your home appliances is getting higher and higher, and the work efficiency is getting lower and lower, please be vigilant when disassembling the machine, you may encounter the Xiaoqiang family group on patrol.
Allergens that people ignore are in the top 10 of the allergen detection list
Cockroaches carry a wide range of germs and have been proven to be an important factor in triggering allergies and asthma. At present, in the detection of major allergens, cockroaches rank among the top 10 allergens detected.
The ** reaction department of a hospital has conducted inhalation strain agent testing on 1730 patients with allergies**, and the results show that in addition to the house dust and dust mites that I am familiar with, the positive rate of cockroaches is as high as 422%, ranking 4th among the top 10 allergens, properly "among the best".
In the investigation report of "National Multicenter Bronchial Asthma and Allergic Rhinitis Outpatients Responsiveness to Cockroach Allergens", Academician Zhong focused on the harm of mites and cockroaches, and the report also introduced that cockroaches are a new "infectious body" that scientists are now studying. At present, there are many people in the south where cockroaches are focused, and many people are allergic to cockroaches**, which seriously induce allergic rhinitis or asthma.
In terms of regional attributes, the positive rate in the south is higher than that in the north and east.
In summary, cockroaches are one of the main allergens in patients with asthma and allergic rhinitis.
Cockroaches are the main indoor allergens and can be divided into contact, inhalation, and ingestion allergies
Cockroaches are the main indoor allergens, not only the cockroach itself, but also the secretions of cockroaches, including its saliva, excrement, dander, molting, and insect corpses. Therefore, anything that has been bitten by cockroaches, places that have been contaminated with small black feces, and the skin that cockroaches have changed their skin once in their life, are allergens.
According to incomplete statistics, the incidence of reactive diseases related to cockroaches has increased rapidly in recent years, especially in southern China, because the environment is humid and humid, and the hot and humid environment is very suitable for the growth and reproduction of cockroaches.
There are a lot of cockroaches in the kitchen, cupboards, and closetsThey appear in droves every night. It's disgusting to crawl around in the kitchen, and a pile of cabinet drawers come out as soon as you open them. Why do so many cockroaches appear at night?
Because it is more afraid of light, it usually comes out at night when it is dark, and white rabbits will rarely see cockroaches. Cockroaches should be eliminated in time, because once it breeds, there will be a lot of them, and it will not be so easy for you to extinguish them again.
A biologist once said: If there is a global nuclear war, all humans and animals will be extinct because of radiation, cockroaches will not be extinct, the amount of radiation that the human body can endure is 5rems, and cockroaches can endure hundreds of thousands of millions of radiation at every turn, "Xiaoqiang who can't be killed" is not a joke.
Female cockroaches discharge their eggs into the egg sheath, which is generally colloidal and not easily damaged.
There are three main ways for cockroaches to treat egg sheaths, the first is:Stick it to a hidden place with saliva, such as their habitat. The second is:After the egg sheath is produced, it is not separated from it and is dragged on its abdomen。The third is:The egg sheath is allowed to appear outside the body, and then "retracted" back into the body after the egg is laid for best protection.
It can be seen that in addition to the first method, the treatment of the remaining two egg sheaths means that when we step on the female cockroach to death, we will leave the eggs it carries indoors. If they are not damaged, and the environment is suitable, the eggs will hatch and new cockroaches will "appear out of thin air".
Of course, even if it is not discovered, the female cockroach will automatically separate from the egg sheath, and then put the cockroach eggs under the bed, in the sewer, around the toilet, etc., and after a few weeks, a new generation of cockroaches will come out into nests. And in a few weeks, this new generation of young cockroaches will breed even larger next generations, and their numbers are growing exponentially!
The effect of traditional cockroach extermination products is not obvious, and the most important thing is that it is too harmful to the human body, especially pregnant women and children, so we should start from a scientific point of view to find a truly effective, healthy and safe way to exterminate cockroaches.
There are nine ** don't know, in fact, cockroaches are most afraid of the smell of camphor trees!
Cinnamomum camphor, also known as camphor, is one of the scarce tree species in China, the growth period is very slow, it generally takes more than 20 years to become a material, it is a rare and high-quality wood, often used as a material for furniture.
Camphor wood furniture and decorations placed in the living room can exude a quiet fragrance full of the house, so that people can breathe comfortably and feel at peace. WhileThis kind of aroma is precisely the "number one natural enemy" of pests and cockroaches, cockroaches and insects encounter this smell is much more powerful than any insecticide, and it is difficult to protect their lives
