There are at least four basic conditions for cockroaches to settle in a place: a warm climate; Humid environment; The food source is rich and has a multi-gap structure. Cockroaches like the dark and fear the light. They like to go out at night on their stomach during the day and occasionally see them during the day. Generally, after dusk, they start to climb out for food and return to their nests in the morning. The temperature is most active at 24-32℃ and completely inactive at 4℃. There are many things and snacks in the dormitory, which are suitable for cockroaches. Put an end to cockroaches, keep the dormitory clean and tidy, ventilate more, clean up the garbage and put away the food.
What 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. Cockroaches love darkness and are afraid of light. Turning on the light will scare them away at once. 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. Pour some water and put it in the area where cockroaches infest. Cockroaches can trap themselves, which can effectively reduce the density of cockroaches, although it cannot be cured. Ways to drive away cockroaches: 1. Fresh cucumbers drive away cockroaches. Put fresh cucumbers in the cupboard, and cockroaches won't come near the cupboard. After fresh cucumbers are put for two or three days, cutting them and continuing to smell them can also effectively drive away cockroaches. 2. Fresh peach leaves repel cockroaches. Put the freshly picked peach leaves in a place frequented by cockroaches, and the cockroaches will avoid when they smell the peach leaves. Onions can drive away cockroaches. If you put a plate of chopped onions indoors, cockroaches will run away immediately when they smell it, and at the same time, they can delay the deterioration of other food indoors. 4. orange peel will drive cockroaches away, and placing orange peel in areas frequented by cockroaches will effectively drive cockroaches away. Cockroach control 1. To completely eliminate cockroaches, we must first ensure environmental sanitation, clean up in time, including toilets and sewers, and clean up garbage in time. 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, gas cabinets and wire trunking. 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: Eggshell must be burned 2: Flush into the sewer) E. Furniture should be made of aluminum, stainless steel, plastic and other materials, which 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.
What if there are cockroaches in the bedroom?
Cockroaches existed 400 million years ago. And it is one of the few species that can survive the nuclear explosion, which is enough to show its vitality.
Coupled with its super fertility, a cockroach can breed hundreds of small cockroaches a year.
Therefore, it is very difficult to kill cockroaches.
However, I have a way to completely eliminate cockroaches.
There were many cockroaches in my cupboard before, and I couldn't kill them in many ways.
Later, a good friend introduced me to buy an ultrasonic device to drive away rats and cockroaches, and there were no cockroaches at home.
When you go to Tao Bao and call "ult to drive rats", the artifact comes out. The owner's name is Tianzhu Fengfeng. This device is very small, it can drive away not only cockroaches but also mice.
Why are there cockroaches at home? What should I do?

Self-made cockroach killer
Ingredients: potatoes and boric acid. This boric acid can be bought in chemical stores.
Recently, there are many cockroaches at home, and they come back after killing them. Really helpless. Will there be a big cockroach on the ground? I feel that cockroaches are quite smart. Compared with other insects, such as dung beetles and longicorn beetles. They move very fast and appear very strange. . . It's amazing.
I looked it up on the internet and found some earthwork to kill cockroaches. Try it for a while and I'll give you the result when I'm done. . .
Wash the potatoes first, and steam them in the pot for 15 minutes. Take boric acid with the same volume as potatoes, and crush potatoes to make them fully mixed with boric acid. Note that the two must be mixed evenly.
The next step is to crush the mixed boric acid mashed potatoes into pieces, so that the homemade cockroach killer is ready.
The next thing to do is to put the homemade cockroach killer in the place where cockroaches often haunt and wait for it to eat.
What is the reason why there are cockroaches at home?
The first raiders how to deal with cockroaches has existed for more than 300 million years. Most of them grow in warm and humid environment and are ubiquitous in offices and family rooms. Cockroaches are not only a nuisance to others, but also protein in their excrement is an important substance that causes allergic rhinitis and asthma, especially for children living in crowded rooms and cities. How to get rid of cockroaches 1, carefully check sewers, wall cracks, floor partitions and windows to prevent cockroaches from entering. 2, keep the room dry, cockroaches live in a humid environment, so you should be careful not to have any water leakage, especially in the kitchen. 3. Keep the room clean. In a clean and dry environment, cockroaches will feel unwelcome. After eating, the food should be sealed in time, the garbage in the ground and garbage bags should be cleaned in time, and the tableware should be washed with hot water first. Dirty tableware will attract the attention of cockroaches. In addition, stoves and other places should be cleaned regularly. 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 let the cockroach out by interfering with its feeling of external vibration. For example, as soon as you see a cockroach, you can immediately make a hissing sound with your mouth and then pat it quickly, which makes it easier to kill it. Chemicals can also be used against cockroaches, and there are five thousandths of dichlorvos, or three thousandths of deltamethrin, boric acid powder and so on. It can be sprayed on the place where cockroaches live and move, or put a few pieces of cockroaches to kill cockroaches. There is a kind of pyrethroid insecticide called "cockroach killing", which has been tried in the kitchens of cargo ships, oil tankers and Yangtze River passenger ships of the Maritime Safety Administration. Spraying 300 ml of liquid medicine in a 60 cubic meter cabin, the cockroach immediately got excited and agitated, climbed out and fell to death.

Why are there cockroaches at home?
Cockroaches are nocturnal Kundan, which is extremely fertile. If the climate is mild and moderate, they can breed a nest in ten days, with 40 to 50 animals in each nest. In spring, everything recovers and the climate gets warmer, which is the most prosperous season for cockroaches to breed. Killing a cockroach at this time is equivalent to killing hundreds of thousands in summer and autumn. So how do you kill cockroaches?
(1) Cockroaches mainly live in the kitchen. They live in all the gaps between the cabinet frame and the wall, in the cracks in the wall, and in the drainage pipes of the kitchen. You can spray pesticides to plug the gap and scald it with boiling water.
(2) If there are too many cockroaches in the decorated room, it's best to close the doors and windows and use alcohol lamps to light 10% Didi Wei. Burning for an hour or two can kill a lot of cockroaches. But remember, cockroaches are extremely vital, and sometimes they are just in a coma, not really dead. So you can't throw it away as garbage. You'd better scald it with boiling water. Otherwise, many cockroaches will wake up in ten minutes, which is equivalent to "releasing tigers to the mountains".
(3) Put the sticky paper in the place where cockroaches often haunt. This method has little effect, which is equivalent to "waiting for the rabbit".
(4) Cockroaches should not be beaten by flies or trampled to death by their feet. It is best to stick one on the other with cockroach paper, which is very accurate and effective. Stepping on your feet will spread a lot of germs and viruses on cockroaches everywhere.
Practice has proved that it is ineffective to completely eliminate cockroaches by one family, and cockroaches from neighbors will crawl in, which requires large-scale collective action.
To eliminate cockroaches, it is necessary to take concerted action and take measures that pay equal attention to environmental control and chemical control;
(1) For the miscellaneous, chaotic, broken and dirty environment, it is necessary to "clean up three things and block one wall" (remove sundries, clean egg sheaths, clear cockroach tracks and block cracks in walls) to reduce cockroach breeding grounds.
(2) Poison bait, medicine pen sealing, residual spraying and powder spraying are used to kill cockroaches.
