When I first graduated, my colleague and I rented a 40-square-meter room in an old community, compact but tidy, but two girls, with a lot of things and things, looked full.
One morning I just entered the kitchen, I saw a "cricket" crawling on the ground, we live on the 6th floor, suddenly there was a "cricket" is very strange, I quickly called my colleagues to catch it, but my colleague came to see, screamed "cockroaches", and at the same time took off the slippers, snapped the cockroach to death on the ground, I was simply dumbfounded, came back to my senses before goosebumps.
You might think that the reason we have cockroaches is because we don't do a good job of hygiene, but let's be honest, we're really not that dirty. The weather in the south is warm and humid, which is especially suitable for cockroach breeding.
It can also reproduce asexually, and female cockroaches can lay eggs even if they don't mate.
Cockroaches are not picky eaters, and even eat their own poop, even if they don't eat or drink, they can live for three months.
When you're asleep, it comes out to party. One second, it's crawling down the drain and toilet, and the next, it's crawling to your food, dishes, clothes, bed, towels, and toothbrush. What's even more terrifying is that cockroaches have a habit of eating and pulling at the same time, and it is easy to spread the bacteria, protozoa, fungi and eggs they carry to our food and utensils.
Mild diarrhea can cause gastroenteritis, and in severe cases, it will enter the stomach and find dense parasites!
You may have heard this rumor:
When you see a cockroach at home, it means that hundreds of cockroaches have settled in your house, eating and living with you.
It's creepy to think about, right?
CockroachesIt is an ancient insect and a natural enemy of humans.
After thousands of years of evolution,CockroachesIt has fully adapted to the living environment and food of human beings, and has bred a large number of offspring.
We call itCockroachesfor".XiaoqiangTrue to its name, this pest is small but has a strong vitality.
There are two main types of cockroaches that are common in our lives, which are:German cockroach (Blattella germanica) and American cockroach (Periplaneta americana).。The former is distributed throughout the country, and the latter is mainly distributed in the south of our country.
They are not afraid of the cold, they do not choose a place to live, they are there where there are people.
No matter how clean your home is or how many pesticides you use, it's inevitable that one day when you open the cupboard or wardrobe, you will look at each other with a "little strong".
Cockroaches are arguably the most closely related and troublesome insects to us.
Speaking of the new four evils, then we have to talk about what the old four evils are: people born in the sixties of the last century still remember the "four evils" movement vividly.
The so-called "four pests" refer to flies, mosquitoes, rats, and sparrows. Later, one of the old four evils, "Sparrow", was rehabilitated and has been replaced by "cockroaches".
WhyThe position of the head of the new four pests should be reserved for cockroachesWhy not mosquitoes, flies and rats?
01 Fertility-- Geometric growth
It is reported that there are about 5,000 species of cockroaches in the world, and there are more than 250 species in China. The cockroach race base is large, and even if 90% is killed, the remaining 10% can reproduce many offspring.
Taking the most common German cockroach as an example, cockroaches are juvenile within 2 months after birth, and after having fertility, they can mate 6 7 times in their lifetime, laying about 40 eggs each time, and these 280 eggs can also mate with each other and across generations, showing geometric growth.
02 Reproductive characteristics- You can give birth without a male
A female cockroach can reproduce tens of millions of offspring, and some cockroaches can also achieve "parthenogenetic survival", that is, "autologous reproduction", such as the American cockroach.
03 Ability to perform- will play dead
Cockroaches have developed a self-protection mechanism for hundreds of millions of years, and if humans go head-to-head with cockroaches, they may escape by playing dead.
Some cockroaches, even if they are "beheaded", do not really die. Scientists have found that cockroaches can survive for a week without a head because cockroaches breathe mainly through the valves of the small holes in their bodies, not their brains.
04 Ability to carry hunger- You can live for 42 days without water or food
Cockroaches eat not only food, but also garbage, feces, bloodstains, phlegm, and even wood, paper, rags, etc.
When food is scarce, cockroaches kill each other and eat the corpses of their companionsWith sufficient water and food, cockroaches can live for 90 days and 1 year;At room temperature, the German cockroach can live for 7 to 10 days without eating or drinking, and can survive for 42 days without water or food.
05AdaptabilityNot afraid of high radiation and toxic gas
Cockroaches like darkness and fear light, hiding in dark, damp crevices with food during the day, and coming out at night to forage and mate. In general, the temperature is most active at 24 to 32 hours and completely inactive at 4 hours.
In the tropics, cockroaches breed and move throughout the season;Even in alpine areas, cockroaches can move and breed as usual as long as there is indoor heating equipment in winter.
Studies have shown that cockroaches can still survive for a long time in vacuum, high radiation, toxic gases, underwater and other environments, far beyond human tolerance.
06 Communicative skills- I like to get along with people the most
As early as when humans lived in caves, cockroaches coexisted with humans, and their living environment was similar to that of humans, such as requirements for water, food, and temperature.
People's daily activities are actually helping cockroaches to survive, for example, with furniture handling, logistics transfer, luggage consignment, etc., cockroaches will be brought into the home environment, which is difficult to prevent.
Most people's first impression of cockroaches is that they are dirty, disgusting, ugly, and difficult to look at
In fact, cockroaches are not only annoying, but also spreaders of bacteria and viruses!
American biologist Smith Wu has discovered after many experiments that only one family is "raised".Cockroaches can carry more than 40 kinds of pathogenic bacteria that are harmful to the human body!For example, Yersinia pestis, dysentery bacillus, Pseudomonas aeruginosa, Escherichia coli.
In addition, cockroaches can also carry a variety of pathogenic bacteria that cause food poisoning in humans!For example:Penicillium, Aspergillus flavus, rhizase, yeast, etc.;
The so-called "disease enters from the mouth", cockroaches leave these germs in our food, and after entering our body through the mouth, they cause lesions, which is difficult to prevent!
In addition to bacteria, cockroaches are more "good" at spreading viruses!
The study found that cockroaches carry deadlySarkozy virus, hepatitis,Viruses such as polio, if they are exposed to or eat foods that breed "cockroach virus" for a long time, the chance of causing viral infections is extremely high!
Sarkozy virus:
Coxsackievirus is an enterovirus, a common type of virus that infects the human body through the respiratory tract and digestive tract, and after infection, people will have cold symptoms such as fever, sneezing, and coughing. In general, infants and young children are mostly infected;Children under 5 years of age, especially those under 3 years of age, can detox for up to a month. After the virus infects the human body, it can cause upper respiratory tract infection, acute myocarditis and other diseases, posing a serious threat to the health of infants and young children
Hepatitis:
China is a high-incidence area of viral hepatitis, which is a general term for liver inflammation caused by bacteria, viruses, parasites, autoimmunity and other leading factors. Both children and adults can be affected, and viral hepatitis due to viral infections is common.
Whether hepatitis is contagious or not is mainly determined by **, and viral hepatitis A and E are more contagious and can be transmitted through the digestive tractType B,Viral hepatitis C and D are transmitted through blood, including through blood.
Polio:
Poliomyelitis, also known as "polio", is an acute infectious disease caused by a virusIt is highly contagious. Humans are the only known natural host of the poliovirus, and the virus carried by cockroaches is also one of the main routes of transmission, and the virus enters the intestine through the mouth and multiplies in the intestine.
After being infected with the virus, some patients may have fever, headache, sore throat, and fatigue. In addition, because the poliovirus can invade the nervous systemPatients may also have flaccid paralysis and, in severe cases, death due to paralysis of the respiratory muscles.
There is a lack of effective ** methods for the disease, and vaccination to prevent infection is key!
After reading these terrible statistics, I believe that no one wants to be in the same room with cockroaches!
Kill cockroaches, always complain that the method is wrong, the effect is not good, and the expected effect cannot be achieved, but you know what?There are a few pits that are easy to step on when killing cockroaches, have you also entered them?
Several misunderstandings. 1. Shoot to death and it's over
This method is not recommended, in order to get rid of cockroaches, we may have tried many methods, but don't just shoot or trample to death!It is said on the Internet that Xiaoqiang can still live after stepping on death, but it is actually a bit of a rumor. What's really scary is that even if the cockroaches are photographed, the eggs can still survive, and after a few days, a litter of tigers and tigers will be born!
2. Powerful cockroach medicine with fast effect
This method is also not recommended, some drugs have a good effect for a short time, but after a period of time, cockroaches grow geometrically, the reason is that cockroaches can produce drug resistance!And many powerful cockroach killers are very toxic, and they are really unsafe to use!
3. Smoke
This method needs to consider the environment and place problems, smoke cockroach medicine, is to release the medicine mist by combustion to kill insects, the advantage is to kill cockroaches in a large range in a short period of time, close the windows and doors when using, and ventilate when you finish the work.
4. Mothballs
I put a few packets of mothballs in the stench, and I always found traces of cockroaches in all corners.
But when I saw the news, I found that many mothballs on the market were not extracted from plants, but synthesized with naphthalene, which smelled and had little effectIt can also cause harm to children and pregnant women!I hurriedly threw it away.
And mothballs look like sugar,Babies and pets are easy to eat by mistakeSimilar accidents can often be seen.
5. Spray insecticides
First of all, let's talk about the insecticidal principle of spraying. There is a spray type insecticideDirect contact poisoningwithPoisoning by drug residuesThe two modes of action, which of a particular pesticide works (or both), depend on the active ingredient of the insecticide.
The former is throughSpray directly on the cockroachTo kill insects, many household sprays that claim to be green and environmentally friendly are of this type. Their active ingredients are generally essential oils or surfactants (to put it bluntly, soapy water), which can have a better effect when sprayed directly on cockroaches, but it is useless if they are not sprayed on cockroaches.
It can be seen that the efficiency of this method is actually justSlightly higher than slippers, andKilling the few stupid cockroaches that accidentally show their heads won't solve the cockroach problem in your home
The latter dependsResidual drug on the surface to kill insects, when insects pass over a place where insecticide remains remainInsecticides rubbing against themYou can kill them.
In agricultural production, some pesticides passAbsorbed by plantsto poison pests that feed on plants;Therefore, many pesticides cannot be used when crops are close to harvest.
In order to achieve the desired insecticidal effect in this way, insecticides are requiredHigh residueHowever, there is a high residue insecticideThe security is relatively low, suitable for professionals only. The insecticide spray you buy in the supermarket either doesn't have enough residual toxicity for safety, or the residual toxicity is too high and shouldn't be on the market at all.
Also, as the temperature changes, cockroaches will start mating. The common cockroach species, the German cockroach, can lay eggs at the age of 2 months, and in a lifespan of more than a year, it can lay about 4 8 egg sheaths, each egg sheath contains about 30 48 eggs.
In other words, if there is 1 cockroach waiting to be born in your house now, it will not be long before there will be dozens or even hundreds of its offspring in your house, and after two months, these offspring will also start laying eggs, and within 4 months, the order of 1000 will easily reach.
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.
Many people think that the small body of a cockroach can't withstand the coldAround the beginning of winterThere will be a significant reduction, but it will not.
toBeijing areaFor example, the cockroaches in the Beijing area are mainly German cockroaches, which are small and good at hiding.
It first appeared in hotels, restaurants, small and medium-sized restaurants, etcFood is plentifulof the premises.
Due to the continuous improvement of indoor living conditions and heating conditions, they began to invade homes in large numbers, among themAutumn and winterViolations are most severe in households.
Cockroach invasions ebb and flow with the seasons. As can be seen from the figure, the cockroach infestation rate in households fluctuates in the range of 10% to 20%, compared to other timesincrease, which is also similar to the violations in previous years.
In the second half of the year, mid-November serves as a heating node
Cockroach infestations increased significantly, with a small peak in December after stable heating.
As can be seen from **, the number of cockroaches caught since the beginning of the yearIncrease gradually
among othersThe highest value is reached in September-OctoberCockroach densities remain at their highest levels throughout the yearThe density of cockroaches remained at the highest level throughout the year, and the number of cockroach catches was average in these four monthsMore than 700 of them
You may have doubts about the cockroachesLikes warm and humidIn terms of habits, the number of cockroaches should decrease when the weather is coldBut why are there more and more cockroaches in the house in autumn and winter?
That's because the autumn wind is blowing outside, but inside the houseWarm and comfortable。Cockroaches invade homes along crevices, gutters, and sewers. InAfter heating in mid-November, cockroaches are more in need of humansSurvive in the warmthFinish.
Cockroaches don't need to hibernate, and after entering the house, cockroaches also need to take precautions and set out to find a winter habitat, and we met cockroachesProbabilityNaturallyincrease
What I don't know is that cockroaches are actually most afraid of the smell of camphor trees, which is itDead Hole
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.
According to the Journal of Experimental Biology, cockroaches are first attracted by exhaled carbon dioxide, and then come in the direction of people, building nests and breeding in various corners of the home.
Therefore, the use of odor to kill cockroaches is one of the most scientific and direct and effective methods.
The easiest way to teach you is to use the most natural and harmless smell to kill cockroaches!
