When it comes to cockroaches, friends in the south can be described as "hating it to the core".
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!
As early as more than 300 million years ago, cockroaches have been rampant on the earth, which can be described as ancient living fossils, witnessing almost the entire history of biological development.
65 million years ago in the late Cretaceous, even dominating the world1Dinosaurs that are more than 600 million years old have not been spared in the face of meteorite impacts. However, cockroaches have survived to this day with their tenacious vitality.
It is no exaggeration to say that we humans can all respect cockroaches as the elders of the biological world.
Cockroaches are insects belonging to the order Blattodea, and more than 4,000 species have been discovered.It can bend and stretch, and can quickly pass through even narrow slits that are only a quarter of the width of the body.
It's agile. As the fastest insect on land, even with a small body, it can reach an average speed of 54 kilometers, if you want to change the ratio of **, the speed will reach 320 kilometers per hour, which is faster than high-speed rail in minutes.
And even if you're just as agile, you probably can't because of itI can fly!
It's extremely survivable. In the absence of food, it can live for 3 months;In the case of water shortage, it can live for 1 month.
Even the most extreme "head move" can last a week.
Did you know?In addition to contaminating food and spreading diseases, the notorious cockroaches can also make it"Allergic star" allergies
Cockroaches are importantIndoor inhalation allergens often cause allergic rhinitis-conjunctivitis and allergic asthma.
Scientists have come fromGerman cockroachAt least 10 allergens (components) were isolated from each other, of which,bla g 1is the main allergen and exhibits cross-reactivity with other insects (fruit flies and mosquitoes).
BLA G 1 is produced in the intestines of cockroaches and can be found in:Cockroach droppingsIt was found that it has sensitizing activity, and can upregulate protease-activated receptors and enhance the production of Th2 cytokines.
In a scientific study, it was found that 77% of people who were sensitized to cockroaches produced BLA G1-specific IgE in their bodies.
BLA G2 is another important allergen that cross-reacts with mosquito and fungal allergens。In a scientific study, it was found that 58% of people who were sensitized to cockroaches produced BLA G2-specific IgE in their bodies.
bla g 7(and per a 7) is a tropomyosin that is considered a panallergen due to its structural homologous and cross-reactivity with the tropomyosin of a variety of animals, including dust mites, crustaceans, and molluscs.
In addition to allergens, scientific studies have found:Cockroach chitin and fecesAssociated with allergy-related TH2 inflammation.
As a result, clinical allergies caused by cockroaches and other chitin-containing organisms may be more severe and last longer than those of other indoor allergens.
1. Temperature has a great impact on cockroaches
Cockroaches have relatively high "requirements" for temperature. When the temperature is below 15, the vast majority of cockroaches are inactive or occasionally active;At 15 °C to 37 °C, cockroach activity increased with increasing temperature;Above 37°C, it is in an excited state;At room temperatures above 50, cockroaches tend to die.
Under normal circumstances, the seasonal growth and decline of cockroaches shows changes in population or community size due to changes in temperature.
Shanghai and Jiangsu, Zhejiang region, black-breasted cockroaches are the dominant population of residents, and they are inThe event starts in mid-AprilAs the temperature gradually decreases, the overwintering period is from December to March of the following year.
Southern regionFujian, GuangxiAffected by the climate of the ** zone, there are cockroach activities indoors all year round, but there are also obvious growth and decline rules, such as brown spotted cockroaches and Australian cockroachesThe peak is June；The American cockroach is inJune and August are the peak periods.
Northeast regionThe Japanese cockroach is generally found inThe event starts in early April, the density increased significantly in MayThere was a peak in June, the density decreased in mid-JulyThe second peak was recorded in AugustIn late October, the activity weakened significantly and entered the overwintering period, and the seasonal ebb and flow curve showed a bimodal pattern.
2. Winter is a good time to exterminate cockroaches
Cockroaches are particularly tenacious, so there is no such thing as a natural death in autumn and winter.
Because cockroaches are afraid of cold and their activities are relatively static, it is more advantageous to exterminate cockroaches in winterAutumn and winter, especially after heating in the north, is the best time to exterminate cockroaches. Winter cockroach extermination can also be effective in controlling large-scale outbreaks of cockroaches in summer.
Cockroaches like to congregate in warm, moist, well-fed, and crevice-filled placesTherefore, after central heating, of course, it will "get closer" to the heating equipment. During the period before heating, cockroaches tend to gather behind appliances that can dissipate heat, such as refrigerators, microwave ovens, ovens, and water heaters. In additionThe kitchen is also a place with a high density of cockroaches because of the abundance of food.
1. Where there is food and water. The kitchen at home is where cockroaches are most severe. Because there is an abundance of food in the kitchen, cockroaches generally like to look for food in the drawers of the cupboards, so we usually see cockroaches in the kitchen.
2. Cabinets and drawers. Because cabinets and drawers are closed, and there are many nooks and crannies, cockroaches will use cabinets and drawers as their "safe hiding place". People hidden in cabinets and drawers are not easy to find, and even if they do, they are easy to find. Hideout.
3. Gaps between walls, floors, and various pipes. These places are also places where cockroaches like to go, and they are mostly hidden, and cockroaches can hide well.
4. Dirty and damp places. The dirty and humid environment provides good conditions for the survival of cockroaches, so it is easy to breed cockroaches in a generally dirty and humid environment.
5. Due toRefrigerator, TV, microwaveand other household appliances, compressors and radiators, these places have sufficient heat sources, especially in winter, cockroaches will hide in these places to "keep warm".
Children are very vulnerable to being targeted by cockroaches, mainly for the following reasons:
1.Infants and toddlersDelicate, blowing bombs can be broken, cockroaches like this;
Love to sweat: Cockroaches are mainly tracked and located by the heat, carbon dioxide and odor emitted by the human body. Babies and toddlers emit more heat and sweat a lot, so they are easy targets for cockroaches.
3.Babies often drink milk on the bodyMilky scent, which is the sweet and fragrant target that cockroaches like.
Dark clothes:Cockroaches like people who wear dark clothes. If you go out and dress your baby in darker clothes, it can also be a specific target for cockroaches.
Many mothers will pay special attention to the fact that their children are bitten by cockroaches, because after the child is bitten by cockroaches, not only will the child feel very uncomfortable, but also there will be a lot of "potential harm", and it may also threaten the baby's health.
Cockroaches likeWarm, humid, abundant and crevice-filledplace, so as long as the environment of the room is to the liking of cockroaches, for exampleThe bed is sloppy and damp, has not been washed for a long time, and there are food crumbs, etcEven if a person falls asleep in bed, cockroaches will crawl into bed.
And after people fall asleep, the threat to cockroaches decreases, and cockroaches are not afraid of people who are asleepIt can even bite.
After being bitten by a cockroach, there may not be any reaction at the time, butAfter 1-2 hours, a small lump may form in the bite area, and there will be a small wound in the middle, which is a little itchy, but it is not very painful.
Most people who are bitten by cockroaches do not cause any intense physical discomfort. But because cockroaches live in sloppy places, they may carry a lot of viruses, bacteria and dirt in their bodiesSome people with allergies may have allergies or induce asthma if they are bitten by cockroachesIf you feel unwell, it is recommended to clean the wound and go to the hospital.
Is it reliable to shoot cockroaches with the soles of your shoes?
Based on the above knowledge points, it is not very reliable.
Scenario 1:You shoot a "dead" cockroach and throw it in the trash, and the next day you see that it is likely to be gone....Lost....up....Because of itAnd not really deadand crawled away again.
Scenario 2:If you shoot a "dead" cockroach and throw it into the trash can, but it happens to have eggs, then it is tragic, and countless small cockroaches begin to live and reproduce quietly in the trash can.
Scenario three:You shoot a cockroach to death, so that it doesn't die and scatters its eggs, oh my God.
When stepping on the cockroach to properly dispose of the carcass steps:
Quick response: When a cockroach is found, immediate action should be taken. The quick response helps stop cockroaches from multiplying and reduces the number of eggs.
Use gloves and tissues: Always wear disposable gloves before handling cockroach carcasses to prevent direct contact. At the same time, use a paper towel or paper to wrap the cockroach carcass so that it can be disposed of in the trash.
Clean thoroughly: Immediately after removing the cockroach carcasses, carry out a thorough cleaning. Use disinfectant or bleach to wipe down the surface of the dead cockroach to make sure to kill any eggs that may remain. Also, take care to clean the surrounding area, including floors, walls, kitchen utensils, etc.
The more common way to kill cockroaches in life is cockroach medicine, cockroach spray, etc., first put aside the question of whether it has an effect, we have to consider a problem that isCockroach sprays are inherently toxic and can cause harm to the human body when used indoors.
In addition, many people have a common problem when using cockroach medicine, that is, when using one medicine has no effect, they will add several more, and some people even mix several drugs together to kill cockroachesThis is not the right thing to do. And this kind of medicine will make cockroaches immune and counterproductive.
There are also people who use smokeThis 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.
Under normal circumstances, mothballs have a very limited effect on cockroaches, and can slightly drive away cockroaches in the mothballs cabinet.
However, cockroaches cannot be killed, and cockroaches cannot be completely eradicated. And after a while, the smell of mothballs disappeared, and it had no effect.
Most mothballs contain naphthalene, which is mostly white in color and has a pungent odor. Cockroaches don't like the smell of mothballs and generally keep them away from places where mothballs are freshly placed.
However, everyone should pay attention to one point, the smell of mothballs is also harmful to people, and it is necessary to pay attention to avoid smelling this kind of smell for a long time.
Mothballs will emit a pungent smell, and cockroaches generally do not approach, so putting mothballs in places where cockroaches often haunt will keep cockroaches away and achieve the purpose of repelling cockroaches for a short time.
Cockroaches are afraid of the volatile pungent smell of mothballs, but mothballs only drive cockroaches away, and cannot achieve the effect of complete extinction. Generally, cockroach extermination will not take this method that is harmful to humans and there is no way to exterminate cockroaches.
When it comes to exterminating cockroaches, I'm angry!I have tried all kinds of methods, but there are still traces of cockroaches in the house.
For example, in a cockroach house, there are usually a lot of cockroaches the next day, but in fact, you find that there are noneinsideIt's all small cockroachesIt is rare to catch a huge cockroach that can fly.
There is also a glue bait, which can also kill cockroaches, butIt is easy to be used by children and pets at home to play with and eat by mistake, and to put it in every corner,If you miss a place, they'll make their home there again.
