It's actually on the Zhihu Daily, haha.
[There is no shortage of good cockroach extermination drugs on the market, but there is a shortage of people who can use this medicine correctly, and there is a shortage of people who are willing to popularize this correct use method to everyone]
The following is my lifelong knowledge of exterminating cockroaches (the ability to mix rice and eat), which is open source here......
Updated April 25, 2021 (at the end of the answer): Why do I feel that the number of cockroaches has increased after using cockroach medicine?
……**……**……**……**……**……**……**……**……
Whether it is a home or other place to trap cockroaches with poisonous bait, first you have to find the place where the cockroach is hiding, which is the most critical step to kill cockroaches, otherwise you can't completely eliminate it no matter how expensive and good the medicine is.
And don't put too much faith in cockroach medicine ads.
Cockroach poison bait has a certain attraction for cockroaches, but it is definitely not as exaggerated as advertised. Putting poison bait anywhere indoors can attract all cockroaches, this phenomenon basically does not exist, and the poison bait must be sent to the cockroach habitat to achieve a good killing effect. In addition, the poisoning effect of cockroach medicine is exaggerated, and there is basically no phenomenon that all the cockroaches in the whole litter die after a cockroach eats medicine. If this is really the case, will the cockroach still call Xiaoqiang who can't be killed (we do insecticide, so we can only drink the northwest wind)? The reason why there is such a saying that poison transmission is because in the case of insufficient food, the big cockroach will eat the small cockroach, the small cockroach will eat the feces of the big cockroach, and even the cockroach corpse will be eaten by other cockroaches, and the cockroach medicine has the effect of causing secondary poisoning, so there is this saying. But the reality is that where cockroaches appear in large numbers, it is impossible not to have enough food. Usually, cockroaches will have an abundant source of food and heat near their habitat, and they live a comfortable life with plenty of food and clothing. In this case, if you don't deliver the cockroach medicine to the cockroach's mouth, the chances of them getting the medicine are slim. It has always been emphasized that cockroaches should be exterminated to do a good job of indoor hygiene, in fact, in order to reduce the food source of cockroaches, even if the drug is not in place, cockroaches can be forced to eat.
In a word, as long as you can find the habitat of the cockroach and be able to deliver the poison bait to its mouth, the cockroach can eat lightly without much activity, then the cockroach extermination is a very simple thing.
Cockroaches eat the carcasses of their own kind
(It is recommended that cockroach corpses be found in the process of cockroach extermination, although cockroaches will die of the same kind if they eat poisoning, but this is certainly not as effective as taking medicine directly.) Also, although the cockroach is poisoned to death, its eggs are not dead, and cleaning the corpse in time can prevent the egg sheath on the female cockroach's corpse from giving birth to small cockroaches)
The overturned rice gave birth to a bunch of cockroaches
(The rice is not cleaned up, and the effect of applying medicine next to it to kill cockroaches is very slow)
What if you can't find or find a habitat for cockroaches? Is there a way to get rid zhuanlan.zhihu.com/p/29180374?utm_source=wechat_session&utm_medium=social&from=singlemessage of them completely?
Please click the link zhihu.com/question/26693492/answer/360257024 to exterminate cockroaches in the dormitory
For cockroach control in the kitchen of the restaurant, please click the link zhihu.com/question/42055984/answer/100208794?utm_source=wechat_session&utm_medium=social&utm_campaign=ge13_2&utm_division=ge13_3&from=singlemessage
At home, cockroaches generally appear in the kitchen (when there are more cockroaches, there will also be other places such as restaurants and bathrooms), and when you turn on the light at night, you can see a lot of cockroaches on the stove, floor or wall, and they are almost invisible during the day, so where are the cockroaches hiding?
Generally, the kitchen will have one such cupboard, and most cockroaches hide in this cupboard
German cockroaches like to hide where they are pointed
The gap on the reverse side of the countertop is also a good place for cockroaches to hide
Cockroaches can also be hidden in small household appliances, such as rice cookers, microwave ovens, juicers, dishwashers, and water dispensers, and cockroaches are also very fond of congregating around sockets (these places can provide a heat source for cockroaches). If there are more cockroaches, there will be cockroaches in the gaps of the door frames, the gaps in the tiles, in the sealing strip of the refrigerator door, between the refrigerator and the wall, between the countertop and the wall, the gap in the baffle under the cabinet, in the wall cabinet hanging on the wall, etc.
Where there are cockroaches, you may not be able to see live cockroaches, but there are generally cockroach droppings, and the smell is very bad when you smell carefully, the more cockroaches, the stronger the smell, so it is relatively easy to find.
The above are the feces of German cockroaches, the particles are relatively small, and some of them are thin and stick to the door panel
This is the feces of a black-breasted cockroach with large particles (that black bean is an egg sheath that can give birth to dozens of cockroaches)
If you find the base camp of cockroaches, you can use medicine, which one is used for so many types of cockroach medicine? Here I recommend cockroach bait and cockroach granules. In terms of effect, there is no difference between domestic drugs and imported drugs, as long as you follow the instructions for use and apply the medicine to the cockroach habitat mentioned above, the cockroaches can basically be solved, and then prepare brooms and rags to collect the corpses of cockroaches. Generally, in the case of proper application, there will be poisoned cockroaches the next day, lying there with a bulging stomach and struggling, the vast majority of cockroaches will die in about three days, and the cockroaches at home will be basically eliminated in ten days to two weeks. During the whole cockroach eradication period, they can live a normal life and have basically no impact.
The size of the glue bait is the size of the rice grain at the bottom of the hinge, if there are more cockroaches, you can order a few more to ensure that the dosage is sufficient. Cockroach extermination granules are simpler, pour it on paper, or in a small container, and put it in a cockroach habitat or a place where they often hang out.
Cockroaches are eating glue bait."
Cockroach carcasses will appear after cockroach extermination
Here is an explanation:
As mentioned above, it is easy to find cockroach corpses, and it is when there are more cockroaches. However, if there are not many cockroaches in the house, only one is seen occasionally, or if it is the first time a cockroach is found in the house, in this case, the chance of finding a corpse will be relatively small. There are not many live cockroaches, and it is unrealistic to ask to see a large number of cockroach corpses. Also, cockroaches hide in hidden places most of the day, and they don't die on the spot after taking medicine, so most of them die in hidden places after being poisoned. At this time, it is no longer possible to judge the cockroach extermination effect by how many cockroach carcasses are found, as long as the live cockroaches are not present, then our prevention and control purpose has been achieved.
In addition, there is a crude method of exterminating cockroaches - dropping cockroach extermination smoke bombs. When this big killer is used, the smoke is billowing out, the smell is big, the throat is choking, the eyes are spicy, and there will be a faint smell of smoke in the room when the smoke is gone. And it is only suitable for places with small space and good sealing.
This method only has a quick effect, but it is more effective against cockroaches.
There are some restrictions on the use of smoke grenades: the room is well sealed, personnel and pets must leave the venue, food and tableware should be sealed and kept, the cabinet doors should be kept open, the smoke alarm will not be triggered, personal protection should be done when putting it in, the floor should be carefully burned, it must be kept outside for a period of time after the release is completed, to prevent the smoke from drifting out of the cracks in the doors and windows, and the neighbor from falsely reporting the fire; keep it for at least 2-3 hours, first open the window for ventilation when entering the room, and then do the cleaning work after the smell of medicine has dissipated.

Compared with the poison bait trapping method, the effect is immediate, but the cockroaches that are hidden deep may not be eliminated. Although the poison bait trapping method is slightly slower, it can completely eliminate cockroaches.
When we usually do cockroach extermination services for families, we use glue bait and granules to trap cockroaches, which can basically solve the problem at one time.
To add, share a pose to find cockroaches in the crevices
@张海鹏
I posed for a photo, the hairstyle and shoes are the most handsome, but unfortunately I didn't get this angle
To find cockroaches, you must be willing to bend your knees, turn your neck 270 degrees, and sometimes put your face on the floor (it can be seen that we are indeed making hard-earned money)
With this angle, you will find a sight that will make you eat a pound
These cockroaches are hidden in the crevices on the edge of the countertop, and they don't know if they don't see it, and they are startled when they look at it
Put the medicine in, and the needle will work
The next day, a dead cockroach fell.
On the three heavy mouth videos
When cooking, cockroaches are separated from your body
A cockroach gathering place found in a wooden cabinet
(Point the medicine directly at the corner where the cockroach is found, and the cockroach killing effect will be very obvious)
Cockroaches in the crevices on the back of the dining table
(The cockroach in this gap is impossible to find from the normal perspective, unlock a new posture and discover a new world)
said it in such detail, if there are still people who can't figure it out, then forget it, don't destroy it, you are born with great blessings and noble lives, and this inferior work is still left to our professionals. You spend some money to watch us perform for you - the old military doctor, a special miracle drug, a needle effective, the effect is stable, and you can go with the cure.
@xin lu Thank you for the reminder, haha, won't be unemployed. This kind of thing (I wrote about family rodent extermination earlier) is really not something that can be done well by looking at a post. Although I wrote in detail, this is just an idea and operation essentials for killing insects and rodents. In the actual prevention and control work, almost every family encountered is different, and there are many factors that may affect the effect of insecticide and rodent control (room type, decoration style, sanitary conditions, customer's living habits, etc.). In order to produce rapid results, it is necessary to adapt to local conditions, and a variety of measures may be required to take comprehensive control measures. To do this, it is necessary for the prevention and control personnel to have rich work experience. Experience and proficiency are things that you can't learn for a while.
In the same way, our family customers are mainly rich people, people who understand, "lazy people", people who recognize us and people who are afraid of rats and insects.
Speaking of which, I would like to say a few more about the service fee.
What we do is door-to-door service, even if our drug and technology costs are low, but the labor service cost is not low. To take the simplest example, can it be the same price as going to a restaurant to eat a meal and paying to invite the chef home to cook a meal? Can it be the same fee standard for going to the hospital to see a doctor and inviting the doctor home to see a doctor? Maybe after we come to the door, the work time is only a few hours, but we need to arrange the schedule in advance, dispatch personnel, prepare medicines and equipment, and the most important thing is that it takes time for us to go back and forth, and more than once we come to the door, and these costs are of course paid by the customer. Shanghai is a city where the cost of living is already very high, and we have to survive and provide better services to more people, so we have to make a profit.

Wouldn't it be great if you could become a pest control consultant on your mobile phone and immediately consult the problem when you encounter rat problems in your life. Even, when you are lonely, lonely and cold, I can chat with you and relieve your inner sorrows...... The main business is to kill insects and rodents, and the side business is coquettish and cute.

Several close friends reported to me that the cockroaches could not be completely eliminated with glue bait, and only part of them were killed, and the cockroach eradication failed.
I think the main reason for the failure is that it is not used in the right way (not on the premise of counterfeit medicine). Killing cockroach bait is like a weapon to kill the enemy, if a martial arts master uses it, then it can exert its maximum power and destroy a large number of invading enemy troops. If a weak scholar uses it, not to mention how powerful it can be, it is a blessing not to injure himself. Cockroach extermination with glue bait is the simplest and most efficient method of all cockroach extermination methods at present, it has the characteristics of safety, environmental protection, high efficiency, economy, simplicity, and wide range of applicable places, so it is also a common method used by professional insecticide companies to do cockroach extermination services for customers. Buying glue bait or insecticide is different from buying other goods, you must ask the seller for the correct and detailed use method when buying, otherwise, you will not use it correctly when you buy it, then it is just a glue bait, not a weapon to kill cockroaches (in fact, how to use glue bait, many sellers can only say a rough idea, most of them have no actual combat experience). The instructions for use on the drug label are only a brief introduction, and there are no specific steps to operate, and the manufacturer seems to be testing the user's understanding.

Pharmaceutical and medical equipment distributors sell pesticides to our experienced professionals, and they will also do a PPT training. You waited for Xiaobai to buy drugs without technical guidance, relying on understanding and understanding of the use of drugs, and it was good luck to make an effect, and it was normal if it didn't work. So friends who failed to exterminate cockroaches, don't be too depressed. Believe me, read my post today, and tomorrow there will be no more inextinguishable cockroaches in your house.
(Image from Baidu)
Let's talk about the correct use of cockroach bait:
1. Requirements for non-professional operators:
Not afraid of cockroaches, adults, normal people, male or female. Be in a happy mood, not impatient, careful and patient (some people may not even have the patience to read this answer, how to talk about killing cockroaches), not afraid of dirty, not afraid of tiredness, do a good job of personal protection, wear gloves and masks (in fact, it doesn't matter if you don't wear them, you can wash your hands when you are done);
2. Requirements for the on-site environment:
Keep the pesticide application site clean, ventilated and dry as much as possible, seal and store food ingredients, clean up kitchen waste food residues in a timely manner, and avoid the elderly, children and pets as much as possible (if you can't do it, make sure they can't touch it), and you can't use aerosol cans and other repellent insecticides at the same time (its insecticidal principle and glue bait contradict each other);
Do not use aerosol cans and other highly repellent insecticides at the same time on site (its insecticidal principle and glue bait contradict each other)
This is very important, so emphasize it once.
3. Pesticide application process:
Take the kitchen, for example. Once in the kitchen, start at the door frame, follow one direction, circle around the kitchen, and finally return to the other side of the door frame. And vertically, from the baseboard of the floor to the gap between the ceiling and the cabinet. First, keep a squatting position (you can kneel with a big belly), and make a circle in the low horizontal direction such as the baseboard, the cabinet under the stove, the refrigerator and the wall. Then, stand up and make a horizontal circle of countertops, appliances, and tile corner joints. Finally, make a circle of the wall cabinet and the gap between it and the ceiling. In this way, basically the entire kitchen is covered, and in the process of doing it, try to look at it from as many abnormal perspectives as possible, and cockroaches hide in places that cannot be seen from normal perspectives. Where is the specific glue bait, I really can't describe it in words, here I owe you a bunch of pictures, go back and sort out the pictures and make it up immediately.
In film and television dramas, heroes can practice magic skills by picking up this cheats, I really don't know if the author of the cheats is super clear, or the hero's comprehension ability is strong. Forgive me for not being good enough, I have to use a picture caption to make it clear.
When there are a lot of cockroaches, the hinges of the door frame look like this
In this case, the medicine must be given enough, so that the cockroaches are full and good (if there are not many cockroaches, one or two points can be ordered)
at the hinges of the cabinet
in the water dispenser
The side of the drawer
The reverse corner of the cabinet shelves
Next to the socket, inside the heat dissipation holes of various kitchen appliances, especially those that have been idle for a long time, must be treated
tile gaps
If you don't dare to find or can't find a cockroach habitat, you can just follow the picture and text explanation, it's that simple, it's so direct. Of course, there are many places that need to be put on medicine, so I will not list them all here, leaving a little room for free play.
4. Control of pesticide application amount:
The amount of medication is determined by the size of the room and the density of cockroaches, too much medicine is waste, pollution, too little prevention and control effect is not good, so the amount of medication should be appropriate. The use of glue bait is to point out, and the size of each grain of rice can be used. In the case of many cockroaches, you can appropriately point them larger and denser. (The picture is owed, go back and upload it)
This method of discharging medicine is not advocated, it is too wasteful, and it is not environmentally friendly, and it affects normal life
The size of each grain of rice is enough, and 0.2 grams is already a big stone
5. Appropriate tonic to consolidate the effect:
After the application of the drug, the cockroaches will die one after another, if after two weeks, live cockroaches can still be seen, you need to replenish the medicine in time.
6. Special Circumstances:
What should I do if the cockroach refuses to eat the bait or does not die after eating? This phenomenon does exist in catering units, but I have never encountered it in home cockroach extermination services. Cockroaches refuse to eat glue bait, not because cockroaches have become smarter, but because the palatability of the glue bait is not good, and the cockroach smells unpleasant, how can it be eaten? There may be many reasons for the poor palatability of the glue bait, such as expired deterioration, being polluted by substances hated by cockroaches, and the glue bait itself is not qualified, etc. Cockroaches do not die after taking medicine, on the one hand, it may be because there is a problem with the medicine (fake medicine), on the other hand, it may be that the cockroach has developed resistance, and then it is necessary to replace other effective ingredients to prevent and control it. The reason why cockroaches develop resistance is due to the long-term irrational use of cockroach killing drugs. There is basically no long-term irrational use of cockroach control drugs in the home, so it is difficult to develop resistant cockroaches.
The above is the operation method of cockroach extermination in the home, and the same is true for cockroach extermination operations in dormitories and offices.
Under normal circumstances, the dormitory area is not very large, and the facilities inside are relatively simple, which is much easier to operate than home cockroach extermination. Put the glue bait on the door frame, cabinets, drawers, the reverse side of the bed board, the gap between the cabinet table and the wall, various corners and near the trash can, and put the granules under the cabinet, under the bed, under the table, around the trash can and some other places where cockroaches are found, the cockroaches and easy to get rid of, it's that simple.
The life of a cockroach is called perfect, especially living in the south, it is really abnormal to have never seen a cockroach. Therefore, the flowers of the motherland, face the reality calmly, quickly learn the skills of cockroach extermination, and have a successful experience of exterminating cockroaches, and in the future life, you will no longer have to worry about cockroaches. There may be some unexpected gains......
Office cockroach extermination
Start from the door frame of the office door, and point 1-2 points every half meter or so along the baseboard in the corner of the wall, and each point is about the size of cooked rice grains. The room where no cockroaches were found, a little bit every meter or so. Two points should also be dotted on the hinges of the door frames of each room. Don't let go of all the cabinets in the room, the cabinets where cockroaches are found are scattered at 6-8 points, and the cabinets where cockroaches are not found should also be prevented at 2-3 points. When applying pesticides, it is necessary to take into account that it does not affect the normal work, and the items will not be touched, such as points at the hinges, on the reverse side of the laminate and in some trenches and other hidden places. Generally, the partition groove of the desk, the gap between the desktop and the partition, the computer keyboard and the plug-in board, the reverse side of the telephone, the printer, the water dispenser and microwave oven in the pantry, and the mailroom where there are often items in and out are waiting for a heat source or hidden damp places are the key prevention and control areas.
The distribution of granules is very simple, and the evenly divided granules are placed directly in the places where cockroaches are often infested. For example, around the trash can, under the computer host, under the printer, under the sofa and coffee table, next to the clutter pile and so on. If you find that there are a lot of cockroaches in a cupboard, you can also put 1-2 granules at the same time as dispensing the bait.

Don't ask me how effective spiders and boric acid are in killing cockroaches, I really haven't used it, and my colleagues and colleagues I know have not used it, so I don't know what kind of effect I can achieve.
We eat by eliminating the four pests, and the choice of cockroach extermination drugs and methods determines our income, so in our work, the safe and simple, symptomatic and low-cost cockroach extermination method is what we have been pursuing. The trapping of cockroaches with cockroach bait and granules, that is, the trapping method, is obtained by repeated comparison, continuous screening and continuous optimization in long-term work, which basically meets the above three requirements that we have been pursuing, so insecticidal companies will generally use it.
Effective and effective prevention and treatment are two completely different concepts. Slippers are also effective in fighting cockroaches, can you use slippers to kill all the cockroaches in the house?
Use glue bait and granules to kill cockroaches, which can stand up to scrutiny and inspection, two words - reliable!

If you have pets, children, the elderly or sick at home, can you use this method to get rid of cockroaches?
People in the industry have a clear answer to this question - they can use this method to kill cockroaches, but they will not give a positive reply in their mouths. It's very simple, because we can't afford to take a very small risk. No matter how safe the cockroach medicine is (the safety factor of the cockroach medicine will be added tomorrow), it is always an insecticide, and there is always a certain toxicity, even if this toxicity, no matter how weak it is, no one wants to touch it with their pets or babies. Therefore, try to apply the pesticide in a hidden place, and at the same time do not contaminate the food tableware, pets and babies should be kept away from the cockroach extermination site as much as possible, only in this way can we better ensure the smooth progress of the cockroach extermination work and achieve our goal of cockroach extermination.
Safe medication is not a trivial matter, and it never hurts to be cautious. An absolutely positive answer is a sign of irresponsibility. Durex doesn't dare to say 100% contraception, insecticides, you dare to say it's 100% safe?
So the standard answer to this question is: it can be used, but it must be used with care, and make sure that pets and babies do not touch it. The cockroach carcasses that appear in the later stage should be cleaned up in time to avoid causing unnecessary trouble.

Where do cockroaches come from in the house, and how can I prevent them?

How long can you use glue bait and granules to kill cockroaches?
(I'll answer it right away when it's sorted out)
2017 09 02
Cockroachicidal bait and granules are ordinary insecticides. Their mission is to destroy the existing cockroaches in the room. They do not have the effect of vaccines, it is impossible to go down with one shot, and the house is permanently free of cockroaches. This is the same as treating colds, no doctor dares to say how long you can take cold medicine to keep you from catching a cold. After this cold is cured, whether or not you will catch a cold again is determined by the person's physical fitness and environment, which has nothing to do with the cold medicine that has long been turned into Xiang.
Cockroach medicine can kill existing cockroaches indoors, but it can't stop new cockroaches from re-invading. Whether there will be any more cockroaches in the room is not determined by this medicine, but by the people in this house. (How do cockroaches invade?) )
Kill cockroach bait, in the case of the package intact, the shelf life is two years, once squeezed out of the package, the shelf life is greatly shortened, Bayer distributors give the data is that in the restaurant kitchen in the high temperature and high humidity environment, can last up to two or three months. In a normal environment, the effect will be longer. That is to say, it has always had the effect of killing cockroaches during this effective period, even if there are new cockroaches invading outside, they will be poisoned and killed quickly after taking the medicine. It can make cockroaches unable to survive indoors for a long time, and even reproduce, which indirectly achieves our goal of cockroach control.
Some people say that I have not seen cockroaches in two years since I used this cockroach medicine at home. There have been no cockroaches for so long, in fact, it has little to do with cockroach medicine, it is the environment in which you live that there are fewer cockroaches, and it just so happens that you have not brought cockroaches into the home from the outside in life, so this effect has been achieved.

What happens to the corpse of a cockroach after taking medicine and dying?
Cockroach carcasses may appear on the second day of application, and it will last for about 2 weeks. During this period, if cockroach corpses are found, they should be cleaned up in time, because cockroach medicine can only kill cockroach adults and has no effect on cockroach eggs. That is to say, if a female cockroach with an egg sheath dies, its eggs may still hatch into small cockroaches, and timely cleaning can avoid this phenomenon to the greatest extent. Speaking of which, some friends will ask, there is a saying that cockroaches eat the corpse and pass the poison to death, and how to spread the poison after they are cleaned up. In fact, when we clean up normally, all we clean up are the corpses of cockroaches, and it is difficult for us to clean up the corpses in some hidden places, so let them complete the mission of spreading poison. What if the cockroach carcass in the hidden place gives birth to a small cockroach with eggs? The cockroach medicine has a lasting period of several months, and after a period of time, if a small cockroach is born, it will die after taking the medicine. When these small cockroaches die, the cockroaches in the house will be completely destroyed. What about the cockroach corpse in the hidden place? I thought about it for a while, there is really no good way, do a deep cleaning after 20 days of cockroach extermination, and clean it thoroughly. In addition, the cockroach medicine that may have been put in this way will also be cleaned up together. What happens to a cockroach carcass that can't be cleaned up? It will slowly dry up and won't stench like a rat carcass, so don't worry. I really didn't find out what impact it would have at work, this kind of thing can't be thought about in detail, it's just a few corpses of bugs, and I can't get along with myself if I think too much. Is there a way to prevent cockroaches from dying in a hidden place? It's hard to avoid it with medication. Cockroach medicine is used in conjunction with a cockroach house to reduce the chance of cockroaches dying in a hidden place. It's just a reduction, and it can't be avoided. It is indeed convenient to use only cockroach houses to control cockroaches, and it is indeed convenient to clean up the corpses, but it is difficult to completely eliminate cockroaches, which cannot meet our control requirements.

I often have close friends ask me this: before the medication, I can occasionally find a cockroach at home, but after the medication, I feel that there are more cockroaches, and even during the day, what is the reason?
First of all, it can be answered in the affirmative, cockroach medicine is definitely not a nutrient that can promote the development and reproduction of cockroaches, nor is it a "magnet" that can attract cockroaches in the neighbor's house. However, this abnormal phenomenon is indeed related to cockroach medicine, and it is a poisoning symptom that occurs after some cockroaches take medicine.
At present, most cockroach drugs act on the nervous system of cockroaches and are called nerve agents. Its mechanism of action is to interfere with the normal conduction of nerve impulses, mild interference will make cockroaches appear poisoning symptoms, behavior disorders, severe interference will make cockroaches die directly.
Before taking medicine, the cockroach is healthy, its senses are very developed, and the reaction is also quite sensitive, the slightest wind and grass, it will quickly escape to the hidden corners and crevices. In addition, it is diurnal and nocturnal, and likes to come out at night to forage for food, so the chance of being spotted is relatively small.
Once the medicine is taken, the cockroach is no longer healthy. Some of the greedy cockroaches, with enough medicine, will soon tremble, and then lie on the ground, kicking their legs with their feet facing the sky, and no longer have the ability to crawl, they can only wait for the scythe of death to harvest their lives. The other part of the cockroaches does not take a lot of medicine and can struggle for a while before dying. At this time, it is like a drunk, in a state of excitement, abnormal behavior, and its senses become dull, and it is not so easy to escape, so the chance of being detected is greatly increased.
In this way, the comparison before and after makes people misunderstand that the number of cockroaches increases after taking medicine.
To deal with this "drunk" cockroach, if you are willing to do it, just shoot it to death. If you don't want to, just leave it alone, and it will die soon as well.
