This is how I kill cockroaches.
Remember, cockroach medicine can only treat the symptoms, not the root cause, and pollute the environment, and only occasionally have short-term or psychological effects. Only two methods are really effective, which is my valuable experience in the past ten years.
1。 Where there are mice, there will be fewer cockroaches, so when you hate cockroaches more than mice, you can try to introduce some mice. This is an interesting biological phenomenon that I occasionally found in the university dormitory. Cockroaches were rampant in this dormitory until one day the mice next door came to visit and settled down in the shoe box under the bed, and the number of cockroaches dropped sharply. Everyone is surprised by the rare positive image of mice. Of course, this is the lesser of two evils. Girls will probably drown me with saliva, so it is not recommended.
2。 The real killer is nature. What cockroaches are really afraid of is low temperature, below zero, or even below five degrees, from grandma to eggs. Friends in the south, friends living in HOUSE in America, forget me. ) The specific steps are as follows. In the cold winter, it is best to be below zero outside. Choose a Friday night. After you have a nice meal with your family, put all the exposed food in the refrigerator. Then, open all the windows, hang the quilt on the rope by the window, and open all the wardrobes and suitcases under the window (please take valuables with you). Don't leave a vessel full of water at home. When you have finished all these things, you can either spend the weekend in the south or spend the night at a friend's house. In a word, when you come back five days later, you will be pleasantly surprised to find that there will be no more cockroaches harassing you after three months. Please learn to clean regularly in these three months, and you will live a carefree life.
Finally, as long as your home is really clean, there will be no cockroaches, so you know what to do.
The methods and drugs to kill cockroaches include sticking paper to catch cockroaches, fumigation to kill cockroaches, powder contact killing, and poison bait trapping (poison bait and glue bait). The types and products of drugs include aerosol, powder, poison bait, spray, fumigant, cockroach house and other pesticides.
Among them, aerosol, powder, spray, fumigant and so on are used. Killing cockroaches has the characteristics of quick effect, but the disadvantages are that cockroaches flee everywhere, have a strong choking smell, have short efficacy, rebound quickly and are prone to drug resistance; When killing cockroaches, close the doors and windows and evacuate the crowd. After killing cockroaches, open the window for ventilation to prevent people and pets from being poisoned and polluting the indoor living environment.
Therefore, indoor medication should be based on environmental protection pesticides, and chemical pesticides should not be used to protect people's health. At the same time, we should also choose poison bait (glue bait) with non-volatilization, lasting efficacy and high cockroach killing rate, or invite a pest control company with pest control (PCO) qualification to provide professional cockroach killing services.
Cockroaches have existed for more than 300 million years, most of which grow in warm and humid environment and are ubiquitous in offices and family rooms.

Question 3: What should I do if cockroaches appear in the bedroom? Drugs are not suitable for killing cockroaches in the bedroom. The following methods are recommended. Safe cockroach killing method: 1 Buy a roll of adhesive tape (fly killing paper is also acceptable) and put it in the area where cockroaches often appear. The next morning, many cockroaches will be caught by traps, and the adhesive tape will be burned or scalded with boiling water to kill cockroaches. Repeated use can kill cockroaches indoors.

If you wrap the flashlight in a red cloth, you can hit it with a fly. 3 Fresh milk (milk powder) is also acceptable. Onion juice, boric acid and flour are mixed and stirred into a paste, and placed on a hard paper shell where cockroaches often haunt. Cockroaches like to eat, and they die after eating. Use a bottle with a small belly, put sesame oil around the mouth of the bottle, put some fragrant food in the bottle and put it in a place where there are many cockroaches, and the cockroaches will climb into the bottle and be killed. 5 A spoonful of boric acid is melted in exothermic water, stirred with cooked potatoes and boric acid water into a paste, added with sugar, and placed in a place frequented by cockroaches. Crystals of boric acid can harden the internal organs of cockroaches after eating, and they will die after a few hours. When eating boxed ice cream, there is a little ice cream left in the box.

Don't leave a sanitary corner at home, don't put food in the open air in the kitchen, don't leave stagnant water at home, and block the gap in time to prevent cockroaches from breeding. Check carefully, even the old computer case. People living in a building had better act in unison, so that cockroaches have nowhere to hide. 2. First, find out where Xiao Qiang, the cockroach at home, is hiding. Cockroaches like hot, dark and humid places. Pay attention to water sources, food-rich kitchens, restaurants, bathrooms, sewers, trash cans and so on. Small cockroaches can get into cracks 0.5 mm thick. Adult male cockroaches can get into the gap of 1.6 mm, and female cockroaches with eggs need to hide in places 4.5 mm or two coins thick, especially in narrow and tight gaps, such as gaps between furniture. Any gap larger than 1.6 cm is a refuge for cockroaches. Cockroach nests will also be built where paper bags, boxes and corrugated paper piles are piled up. Some people pile books, newspapers, magazines or cartons next to the refrigerator. The damp and warm refrigerator is a hotbed of cockroaches, and these cartons have become the best breathing space for cockroaches. Cockroach nests are generally hidden in operating rooms, laundry rooms, heating boxes, behind televisions, computers and refrigerators, and in kitchens and sewers. If you want to wipe out the cockroach completely, you must find its nest and kill its eggs. You know, an ordinary cockroach can breed tens of thousands after half a year! In order to eliminate cockroaches, you must do the following work: a. Clean up garbage and unused items, especially books, newspapers and magazines at home. B. Check the bottom and back of furniture, as well as hidden places such as false ceilings, air ducts and wire troughs. C. Fill the cracks and gaps on the ceiling, wall and floor with non-thermal insulation materials to achieve the best sealing effect. D all cockroach remains and egg sheaths must be crushed and removed to prevent egg sheaths from hatching. (1: The egg sheath must be burned. 2: Rush into the sewer. E try to avoid furniture made of aluminum, stainless steel, plastic, etc. This kind of furniture is easy to wash and has no heat preservation effect, so cockroaches are not easy to survive. It is best to keep furniture away from the wall, so it is not easy to hide cockroaches.
Question 4: What if there are cockroaches in the bedroom? 1. Onions can repel cockroaches. Cockroaches are afraid that chopped onions have a strong taste. If you put a plate of sliced onions in a cockroach infested place, make sure that the cockroach runs away immediately.
2. Drugs for killing cockroaches. Now many places sell drugs to kill cockroaches. You can buy some and put them according to the instructions, which is also a good way to kill cockroaches.
3. To catch cockroaches with sugar bottles, use 1 ~ 2 cans, put 3 spoonfuls of sugar water in boiling water, and put the bottles where cockroaches are active. When cockroaches smell sweet, they will fall into the "trap" of canned food. Use this method when there are few cockroaches.
Tung oil is used to kill cockroaches. Buy 150g tung oil, boil it into a sticky colloid, and coat it on a board or cardboard. Put oily food in the middle as bait, and cover other foods. Cockroaches will stick to it immediately when they come to feed.
5. Poisonous bait kills cockroaches, take borax and flour, a little sugar, and mix well to make bait as big as rice grains, which will poison cockroaches. Be careful not to let children or pets eat it.
6. Cockroaches are afraid of fresh cucumbers and fresh peach leaves. If there are cockroaches in the food cabinet, you can put fresh cucumber slices or fresh peach leaves, and cockroaches will avoid it when they smell it.
Question 5: What if there are cockroaches at home? 1. First of all, the house must be kept clean and tidy. Cockroaches like dark and humid places, especially around the toilet door. If the house is clean, there will be fewer natural cockroaches.
2. Cockroach ingots, also known as oil thieves, especially love oil. Where there is oil, there are cockroaches. The kitchen is a place with a lot of oil smoke, which cockroaches especially like. Be sure to wipe off the lampblack after cooking, so don't feel annoyed, otherwise it will be even more annoying in the future, especially when many people use the induction cooker now, the induction cooker is often covered with lampblack, and cockroaches in the gap of the induction cooker like it very much, so be sure to clean it up, otherwise when cockroaches appear on the induction cooker, in fact,
3. When cockroaches appear at home, prepare a bottle of cockroach spray. Although it can't be eradicated, it can only eliminate cockroaches in front of you. However, when I found a nest, the spray effect was still very good, just be careful not to spray it into the food.
In addition, there is a cockroach catcher now, which should be sold in supermarkets, department stores and shopping malls. If not, it is also available on Taobao. Just put the cockroach trap in a place frequented by cockroaches, and then put food at the four doors of the cockroach trap. It is recommended to put oil or candy. Cockroaches prefer oil, especially oil, which will take effect in a few days. If not, it may be misplaced, or it may be paved with food to lure cockroaches.
Question 6: What if there are cockroaches at home? How can we eliminate cockroaches? Cockroach is a very headache because it is too difficult to get rid of. So,
And then what? Which method can completely separate them? Here are some simple cockroach removal methods for your reference!
Mix 1 part borax, 1 part flour and a little bran to make bait pills the size of rice grains, and sprinkle them on cockroaches. Cockroaches will be poisoned if eaten.
Before going to bed at night, you can sprinkle some washing powder on the sink and other places. Cockroaches are poisoned by drinking water.
Put a plate of chopped onion in the room, the cockroach will run away quickly when it smells it, and it can also delay the deterioration of other foods in the room.
Put a little sugar water in the jar as bait, and put the jar where the cockroaches are active. Cockroaches will climb into the tank and drown in sugar water when they smell it.
Put fresh cucumbers in the cupboard, and cockroaches will not dare to go near the cupboard. After two or three days, cut the cucumber and let it continue to smell like cucumber, which can continue to drive away cockroaches.
Put the finished yogurt box (note that there must be some yogurt residue at the bottom and the cover film at the top of the box is half open) in the place where cockroaches often appear. When cockroaches smell it, they will climb into the box and get stuck in the leftover yogurt.
Put the newly picked peach leaves in the place where cockroaches often pass, and the cockroaches will stay away when they smell the peach leaves.
Pay attention to the adaptability of cockroaches, and the above methods should be used alternately frequently to effectively drive cockroaches away.
Question 7: What should I do if there are many cockroaches at home? What drugs, what companies are useless. Please note:
1, blocking the upper and lower pipes:
To eliminate cockroaches, first of all, you should block the connecting passage of the upper and lower sewers in your kitchen, the gas pipeline in the bathroom and the upper and lower pipelines, and then wrap them with transparent tape after blocking them with newspapers. Ventilation pipes in toilets and toilets are the biggest hidden dangers, and there is no way to solve them for the time being. Judging from the current situation, the kitchen lampblack machine and heavy lampblack blocked the entrance and exit, cockroaches couldn't get through, and the bathroom couldn't do anything for the time being.
2. Check the first one carefully. If you can't do the first one, you don't have to look down:
Because cockroaches are very fast, they are very easy to wander upstairs and downstairs. People come to your house with drugs, and you go to other people's houses with drugs. The blockage in the kitchen is the first.
3. Buy a sticky buckle plate and put it in key parts such as kitchen and bathroom;
The gluing plate can be cut into long strips, and the long strips can be connected into narrow strips. There is no need to put any bait, because the bait tastes like a thief. In a few days, you will know the most haunting places of cockroaches at night, usually in front of the kitchen and bathroom. Remember to burn the sticky board and let the cockroaches and their tails die.
4. After three months:
Usually the first wave of dried cockroaches can't stick, and some cockroaches only come out once every seven days. Don't take it lightly at this time, because in three months, the little cockroach will come out, very cute and timid. At this time, the exhibition board is still a good solution, and it will stop for a while after basically eliminating these homes.
Don't ask me who I am, I am a university teacher.
Question 8: There are cockroaches in the room. What should I do? I suggest you buy "Wo Bauhinia" which specializes in killing cockroaches. When you spill medicine on paper, cockroaches will die. At that time, my house was everywhere, under the bed, in the cupboard, and sometimes I climbed into bed. I hate them. Later, I bought a box of this brand of medicine and killed all the cockroaches. I can't see them at home now. Listen to me. I won't introduce you until I use it. Don't worry.

Kill cockroaches with pesticides when no one is at home.
Cockroach is an indoor pest, which lurks during the day and comes out at night. During the day, cockroaches mostly hide in the corner of the kitchen, in the gap of the cupboard, and go out to find food at night.
Cockroaches eat almost everything, fragrant, smelly, hard and soft. Sometimes it will eat the paste in the spine and bite the book; Get into the TV and radio and bite the wire sheath; It even bites the baby's skin and fingers. It also eats feces, sputum and small animal carcasses. It excretes feces while eating, which makes the body dirty, carries germs, pollutes food and spreads various diseases, such as paratyphoid fever, dysentery, tuberculosis and acute hepatitis.
Cockroach is a very old insect with a history of more than 320 million years. The appearance of Carboniferous cockroach fossils is almost the same as that of today's cockroaches. After the Carboniferous, many insects were eliminated one after another because they could not adapt to the changes in the environment, but cockroaches stubbornly survived and became living fossils, which shows how strong their vitality is.
Now, cockroaches have found their footprints in almost every household, and they have also spread to hotels and guesthouses. Even ocean-going ships have become the "free world" of cockroaches. Sometimes, during the day, they swagger on the deck and walls, and no one is watching.
It is not easy for you to catch cockroaches. At night, you sneak into the kitchen, suddenly turn on the light, and see the cockroach panic and suddenly sneak into a dark corner.
Why are cockroaches so agile? This is closely related to its body structure. Cockroaches have a flat body with oily luster, and the rear plate of the abdomen has openings for secreting glands, and the secreted liquid has a foul smell. On its triangular head, there are two small monocular eyes and a pair of big compound eyes. The two upper jaws are fan-shaped, overlapping like scissors, and there are nodules between the teeth, which are like vises when crushing hard objects. There are four tentacles and many short hairs on the mouth. Tentacles are tools for it to collect food, and short hairs are taste and smell organs with sensory nerves on them, which can feed or avoid toxic bait. The nerve endings on the joints of the legs are very sensitive and can detect slight vibrations, so it is not surprising that cockroaches can detect the lightest footsteps. The tail whisker at the end of the tail is a complex vibration sensor, which can sense the direction from the outside and escape quickly.
How to deal with cockroaches? People have invented some methods to trap cockroaches.
Taking advantage of the cockroach's habit of eating sweets, use a small-caliber long-necked glass bottle, put some sweets in the bottle, and coat the bottle with sesame oil. The cockroach got into the bottle, and it was difficult to climb out because the bottle wall was slippery.
Using the habit of cockroaches to drill cracks, use a paper box with some cracks on the lid, coat the box with adhesive and sprinkle some fresh bread crumbs, so that cockroaches can get in and steal and get stuck.
Taking advantage of cockroaches' habit of scraping dirt off their backs on hard objects, we sprinkled some hard and sharp diatomite on the corner of the room. Cockroaches go there to rub their bodies, and too much wax oil will be wiped off the surface. In this way, a large amount of water in cockroaches will be lost and dehydrated to death.
You can also put out cockroaches by interfering with their external vibration. For example, when you see a cockroach, it's easier to hiss with your mouth and then flap it quickly ... >>
Question 9: What if there are cockroaches at home? First, cockroaches like warm and humid environment. They are often hidden in various gaps, such as around various pipes, cabinets, drawers, and even household appliances such as refrigerators, making it difficult to find their traces. Moreover, cockroaches are easy to survive. Number two: Cockroaches eat everything. All kinds of food, fruits, human excreta and secretions, as well as paper, clothes, cigarette butts and drunk tea roots can make them full, but they prefer sweet food. Third, the hatching rate and reproduction rate of cockroaches are very high. The eggs laid by female cockroaches are sealed in egg sheaths and well protected. Even if the female cockroach dies, if its egg sheath is not destroyed, it can still breed small cockroaches, which is one of the reasons why cockroaches are difficult to kill. Fourth, cockroaches like to go out at night, and 75% of the time is hidden in the cracks, so it is difficult to be found and treated. First, buy a special cockroach-killing suspending agent (liquid bottle) and cockroach-killing bait (according to the size of the area), and then get an atomizing sprayer (watering can also be used at home). The suspending agent is mixed with water and then put into a sprayer, and carpet spraying is carried out on places where cockroaches appear and hidden places where cockroaches are easy to hide. You will see many cockroaches' bodies in a short time. Note: After killing cockroaches, clean up dead cockroaches immediately after spraying suspending agent. Never step on them with your feet or pat or hit them with anything. Put them in paper or plastic bags without holes, and then burn them with fire. Never throw it directly into the garbage basket, because there are many small cockroaches in their egg sheaths. They are not dead, and they will soon run out, so they must be burned to kill them completely. Second: plug the hole and wipe the seam. Block the cracks in doors and windows, cracks in walls and holes of various pipes that enter the room outdoors or adjacent rooms to prevent cockroaches from entering the home. Prevent cockroaches from being taken home with food or other items. If hospitalized patients leave the hospital, they should clean up their belongings and make sure there are no cockroaches before taking them home. Do a good job in family hygiene, clean up indoor sanitary corners, and eliminate or minimize the breeding places of cockroaches. Third, you can buy a roll of adhesive tape (or fly-killing paper) to seal the carton and put it in the area where cockroaches often appear. The next morning, many cockroaches will be found in the trap, and the adhesive tape will be burned with fire or boiling water to achieve the effect of killing cockroaches. Repeated use can kill cockroaches indoors. Fourth: cockroach killing tips. Put some leftover cucumbers in places frequented by cockroaches. Cockroaches can't be killed, but they can be driven out of the house. Fresh milk (milk powder) is also acceptable. Onion juice, boric acid and flour are mixed and stirred into a paste, and placed on a hard paper shell where cockroaches often haunt. Cockroaches like to eat, and they die after eating. Find a cockroach's home, wash it with boiling water and use it regularly, and the cockroach will gradually disappear over time; Melt a spoonful of boric acid in exothermic water, stir it with cooked potatoes and boric acid water into a paste, add sugar, and put it in a place where cockroaches often haunt. The crystals of boric acid can harden the internal organs of cockroaches after eating, and they can die after a few hours; In addition, orange peel can kill cockroaches, and placing orange peel in areas frequented by cockroaches will effectively expel cockroaches.
