How to Get Rid of Cockroaches in Your Home

Ways to get rid of cockroaches at home: 1. Clean up the garbage. 2. Keep it dry. 3. Spray detergent. 4. Spray pepper with water. 5. Place onion mustard. 6. Buy cockroach medicine.

1. Clean up the garbage

There are many ways to get rid of cockroaches at home. First of all, keep the room clean. If there is dirt in the house, it is easy to attract cockroaches. Cockroaches like to grow in dirty and messy environments, so we must often take out the garbage, clean the house, and keep the room clean.

2. Keep dry

Cockroaches like humid environments, so be sure to turn off the faucet when you are at home, wipe off water stains on furniture and floors in time, and keep the room dry at all times. You can also place one or two dryers indoors.

3. Spray detergent

Cockroaches like the smell of laundry detergent the most. We can use this characteristic to spray some laundry detergent on the ground. The fragrance will attract cockroaches to eat it. Laundry detergent contains certain toxins, and cockroaches will be poisoned and die after eating it.

4. Spray pepper with water

Many insects like the taste of Sichuan peppercorns, and cockroaches are no exception. Soak an appropriate amount of Sichuan peppercorns in water for about half an hour, then put them in a spray bottle and spray them around the kitchen. This can effectively eliminate cockroaches.

5. Place onion mustard

Onions and mustard have strong spicy flavors, which can drive away cockroaches, so we can put some in the kitchen. Corners are most likely to hide cockroaches, so put more in the corners.

6. Buy cockroach medicine

We can directly buy professional cockroach elimination medicine, which is effective and fast, but when using it, we must be careful not to let children and pets come into contact with it to avoid accidental ingestion and poisoning.

There are a lot of cockroaches in my house. How can I kill them all at once?

It is difficult to clean up cockroaches all at once, but you can still prevent them from breeding by using some methods and keeping your home clean and hygienic.

Here’s how:

1. Sugar water bottle method to catch cockroaches

Take 1-2 cans, put 3 spoons of sugar water, add half a bowl of boiling water to dissolve it as bait, and place the bottles in places where cockroaches are active. When the cockroaches smell the sweet smell, they will crawl into the can "trap".

2. Tung oil method to kill cockroaches

Buy 100-150 grams of tung oil, heat it to make a sticky colloid, apply it around a 15 cm square wooden board or cardboard, put greasy and fragrant food in the middle as bait, and cover other food to prevent cockroaches from stealing food. When cockroaches are looking for food, they will be stuck as long as they crawl to the place with tung oil.

3. Cold and hot insecticide method

Cockroaches have poor resistance to heat. When the temperature reaches above 60 degrees, they will die within a few minutes, and the eggs in the pods will be killed. A common method is to put boiling water into a kettle and pour it into the hidden gaps of the cockroaches to kill them by scalding. You can also use a hair dryer to kill them. As long as you adjust it to the hottest setting, they will die in a few seconds. Move the objects and furniture where cockroaches live to a place below -5°C-10°C and store them for 30 minutes, and the cockroaches will be frozen to death.

4. Cockroach pills

Nowadays, there are many cockroach-killing pills on the market. These pills emit an odor to attract cockroaches to eat. After eating the cockroach pills, the cockroaches will be poisoned and die. Although the seller guarantees that the cockroach pills are only effective against cockroaches and are harmless to humans and other animals, you still have to be careful to place them away from children and pets.

5. Soapy water insecticide

The effect of soapy water is no less harmful to cockroaches than that of laundry detergent. You can dissolve the soap in hot water. The soapy water has a fragrance, but once the cockroaches touch the soapy water, they will slowly die.

6. Artificial product insecticide method

Items for killing cockroaches include sticky cockroach paper, fumigation, contact powder, poison bait (baits and glue baits), and drug types and products include aerosols, powders, baits, sprays, fumigants, cockroach houses and other insecticides.

Additional information

harm

The body surface and digestive tract of cockroaches can carry a variety of pathogenic microorganisms, such as Shigella, Salmonella, Staphylococcus, Escherichia coli, hepatitis virus, parasite eggs, etc. When these cockroaches carrying pathogens crawl onto food and tableware, they may transmit the pathogens to humans. The secretions, excrement and vomit of cockroaches can also cause allergic reactions in humans.

In addition, cockroaches can be artificially infected with bacteria that cause Asian cholera, pneumonia, diphtheria, glanders, anthrax, and tuberculosis. Cockroaches can carry eggs of various worms, such as roundworms, hookworms, beef tapeworms, roundworms, and whipworms. They can also serve as intermediate hosts for various nematodes, such as Echinococcus moniliformis, Hymenolepis shortissima, and Cynocephalus spp.

Cockroaches can also carry a variety of protozoa, four of which are pathogenic to humans or animals, such as Amima dysenteriae and Giardia intestinalis. Experimental studies have confirmed that cockroaches can carry, retain and excrete viruses, including Coxsackie virus and polio virus. Cockroaches can also carry fungi. In Nanjing and Nantong, Jiangsu Province, my country, a variety of fungi have been isolated from cockroaches captured indoors, including a large number of Aspergillus flavus.

Although cockroaches carry a variety of pathogens, it is generally believed that pathogens cannot reproduce in their bodies and are mechanical vectors. However, due to their wide range of invasion and their varied feeding habits, they can move around in garbage, toilets, washrooms and other places, and can also feed on food, so the spread of intestinal diseases and parasite eggs caused by them cannot be ignored.

In addition, there are also reports of allergies caused by cockroach body fluids and feces. Furthermore, factory products, store merchandise, and home food can all be contaminated by cockroach bites, causing economic losses. Occasionally, communication equipment and computers malfunction due to cockroach infestation, causing accidents. Some people abroad call cockroaches "computer pests."

Since I went to college, I have been suffering from the harm of cockroaches. After fighting against them many times, I have the following experience to share with netizens. Years of experience in killing cockroaches show that no matter where cockroaches come from, they will eventually grow into a large nest. The main reason is the sanitary conditions at home. If the garbage and stoves at home are not cleaned at any time, they will eventually become a perfect place to nourish cockroaches. This cleaning cannot be ordinary cleaning. It requires that the house is spotless. There must not be any food exposed outside. Any food residue will attract cockroaches. Therefore, there are only two places that have never had cockroaches, the dormitory of military students and the meditation hall where nuns live. Because there is no food in these two places and they are cleaned meticulously, there will be no cockroaches. When I lived in the military academy, the crazy and harsh military hygiene evaluation resulted in even the deepest part under the bed being clean, so there was naturally no basis for cockroaches to survive. As for the walls of the nun's meditation hall, which were clean and the women were diligent in cleaning, there was no basis for cockroaches to survive. In addition, other places where people live have conditions for cockroaches to parasitize. The following is my experience on how to kill cockroaches. Remember, cockroach medicine can only treat the symptoms, not the root cause, and pollute the environment. It can only occasionally have a short-term effect or psychological effect. There are only two methods that are really effective. This is the valuable experience I have explored for ten years. 1. Where there are mice, there will definitely be fewer cockroaches, so when you hate cockroaches more than mice, you can try to introduce some mice. This is an interesting biological phenomenon I occasionally discovered in my university dormitory. Cockroaches used to be rampant in this dormitory, unscrupulous, until one day the mice next door came to visit and made their home in the shoe box under the bed, and the number of cockroaches decreased sharply. Everyone was surprised by this 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 move is---nature. What cockroaches are really afraid of is low temperature. Below zero degrees, or even below 5 degrees, everything from cockroach grandmothers to cockroach eggs will die. (Friends in the south and friends who live in houses in the United States, just ignore what I said) The specific steps are as follows: In cold winter weather, preferably below zero degrees outside, choose a Friday night, have a good meal with your family, and put all the food exposed to the outside in the refrigerator. Then, open all the windows, hang the quilt on the rope by the window, open all the wardrobes and suitcases and put them under the window (please take valuables with you). Do not leave utensils filled with water in the house. When you have done all these, you can go to the south for the weekend or stay at a friend's house. In short, when you come back after 5 days, you will be surprised to find that there will be no cockroaches bothering you for three months. Please learn to clean your house diligently during these three months, and you will be worry-free for the rest of your life. The last sentence, as long as your home is really clean, there will be no cockroaches, so you know what to do. The methods and drugs for killing cockroaches include sticky cockroach paper trapping, fumigation, contact killing with powders, poison baits (baits and glue baits), and the types and products of drugs include aerosols, powders, baits, sprays, fumigants, cockroach houses and other insecticides. Among them, the characteristics of using aerosols, powders, sprays, fumigants and other insecticides to kill cockroaches are fast results, but the disadvantages are that cockroaches flee and hide when killing cockroaches, the choking smell is strong, the drug effect is short, cockroaches rebound quickly, and they are easy to develop drug resistance; when killing cockroaches, doors and windows must be closed, and people must be evacuated. After killing cockroaches, windows must be opened for ventilation to prevent people and pets from being poisoned and polluting the indoor living environment. Therefore, indoor drugs should be mainly environmentally friendly insecticides that do not contain chemical pesticides to protect human health. At the same time, it is also necessary to use baits (glue baits) that are not easy to volatilize, have long-lasting drug effects, and have high killing rates for cockroach control, or ask pest control companies with pest control (PCO) qualifications to provide professional cockroach killing services. Cockroaches have existed for more than 300 million years. Most of them grow in warm and humid environments and are common in offices and home rooms. Cockroaches are not only a kind of guy that others hate, but the 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 the sewers, cracks in the walls, floor partitions and windows to prevent cockroaches from entering. 2. Keep the room dry. Cockroaches mostly live in humid environments, so be careful not to have any leaks, especially in the kitchen. 3. Keep the room clean. In a clean and dry environment, cockroaches will feel unwelcome. :-). After eating, seal the food in time, clean the garbage on the ground and in the garbage bag in time, and rinse the tableware with hot water first. Unclean tableware will attract the attention of cockroaches. In addition, stoves and other places should also be cleaned regularly. 4. Use insecticide to eliminate cockroaches when no one is in the house. Cockroaches are household pests that hide during the day and come out at night. During the day, cockroaches mostly hide in the corners of the kitchen and in the cracks of the cupboards. At night, they move around to look for food. Cockroaches eat almost everything, whether fragrant, smelly, hard or soft. Sometimes they will chew the glue inside the spine of a book and tear the book; they will get into the TV and radio and bite the wire sheath; they can even bite the skin and fingers of babies. They also eat feces, sputum and the corpses of small animals. They excrete while eating, making their bodies very dirty, carrying bacteria, contaminating food and spreading various diseases, such as paratyphoid, dysentery, tuberculosis and acute hepatitis. Cockroaches are a very ancient insect with a history of more than 320 million years. The cockroach fossils of the Carboniferous period look almost the same as today's cockroaches. After the Carboniferous period, many insects were eliminated one after another because they could not adapt to the changes in the environment, but cockroaches were able to survive tenaciously and became living fossils, which shows how strong their vitality is. Now, the footprints of cockroaches are almost everywhere in every household, and have expanded to large restaurants and hotels. Even ocean-going ships have become a "free world" for cockroaches. Sometimes, they crawl on the decks and walls in the daytime without paying attention to anyone. It's not easy to swat cockroaches. At night, you tiptoe into the kitchen and suddenly turn on the light. You see cockroaches panicking and slinking into dark corners in an instant. Why are cockroaches so agile? This is closely related to the structure of their bodies. The body of a cockroach is flat and has an oily sheen. There are openings for secretory glands on the back of its abdomen, and the secreted fluid has a foul smell. On its triangular head, there are two small simple eyes and a pair of large compound eyes. The two upper jaws are fan-shaped, overlapping like scissors, with knobs between the teeth, which are like vises when crushing hard objects. There are four antennae and many short hairs around the mouth. The antennae are its tools for collecting food, and the short hairs are taste and smell organs with sensory nerves on them, which are used to find food or avoid poison baits. The nerve endings on the leg joints are very sensitive and can detect even the slightest vibration, so it is not surprising that cockroaches can detect the lightest footsteps. The cerci at the end of the tail are complex vibration receptors that can sense the direction of external stimuli, allowing them to escape quickly. How to deal with cockroaches? People have created some methods to trap cockroaches. Taking advantage of the habit of cockroaches to eat sweet food, use a small-caliber long-necked glass bottle, put some sweet food in the bottle, and apply sesame oil on the bottle mouth. When cockroaches enter the bottle, it is difficult for them to crawl out because the bottle wall is very slippery. Taking advantage of the habit of cockroaches to drill into gaps, use a paper box with some gaps on the lid, apply glue inside the box, and sprinkle some fresh breadcrumbs, so that cockroaches can drill in to steal food and get stuck. Taking advantage of the habit of cockroaches to scrape off dirt on their backs on hard objects, sprinkle some hard and sharp diatomaceous earth in the corners of the room. When cockroaches go there to rub their bodies, the wax oil on the surface will be wiped off too much. As a result, the water in the cockroaches will be lost in large quantities, and they will die of dehydration. You can also use methods that interfere with the cockroaches' perception of external vibrations to extinguish them. For example, as soon as you see a cockroach, immediately make a "hush" sound with your mouth, and then quickly slap it, it will be easier to kill it. Chemical drugs can also be used to deal with cockroaches. Spray 5/1000 dichlorvos, or 3/10000 cypermethrin, boric acid powder, etc. in the places where cockroaches live and move, or put a few cockroach tablets, and cockroaches can be killed. There is a pyrethroid insecticide called "Mie Qiang Ling", which was tried in the kitchens of cargo ships, oil tankers and Yangtze River passenger ships of the Maritime Bureau. When 300 ml of the liquid was sprayed in a 60-cubic-meter cabin, the cockroaches immediately became excited and agitated, crawled out and died. Some of them died after one day of unconsciousness, and some of the tenacious ones could not survive more than five days. Recently, scientists from the National Institute of Genetics in Japan discovered that toads (commonly known as toads) are the natural enemies of cockroaches. In the small animal breeding room of this institute, cockroaches were once rampant and people were helpless. Later, some toads were released in the breeding room, and soon the cockroaches disappeared. After dissection, it was found that most of the toads' stomachs were cockroach remains. A scientist in Kansas, USA, has developed a sex and smell capture device to lure and kill male cockroaches. It is mainly a toxic sticky paper with smell. This smell is exactly the same as the smell of sex pheromones secreted by female cockroaches, which can lure male cockroaches to the sticky capture paper and poison them to death. As long as there is a little bit of this sex pheromone, then male cockroaches within a range of about eight meters can jump into this trap device within five seconds. Dutch scientists have also synthesized a similar sex pheromone. This indicates that the complete elimination of cockroaches is not far away. One day... People generally use these ideal methods to make cockroaches that endanger human health "extinct". Not long ago, foreign researchers also developed a synthetic chemical that can release a special fragrance to induce cockroaches to mate infertilely. If this continues, cockroaches will not be able to reproduce. Prevention and control of cockroaches: 1. Artificial killing: eliminate adults and larvae. During the day, you can clean the cabinets and drawers and kill them when you see them. At night, you can turn on the lights every half an hour after 8 o'clock in places where there are many cockroaches, such as kitchens, food processing rooms, warehouses, etc., and you can get better results. 2. Trapping: Use a glass bottle with a small mouth and a large body, apply sesame oil (or sesame oil) around the mouth, put some fragrant food in the bottle, put it in a place where there are many cockroaches at night, and the cockroaches crawl into the bottle. Kill them the next morning. The drug Yichengning has a relatively ideal effect on trapping and killing cockroaches. 3. Heat killing: Cockroaches are not heat-resistant and die in a few minutes at 60 degrees Celsius. You can use boiling water to pour into the hidden cockroach seams to scald them to death. 4. Blockage: For cockroaches hiding in cracks, cement or clay can be used to fill the cracks so that they cannot crawl out and starve to death. 5. Kill with medicine: Ant-Crossing Ning, aerosol insecticides, pyrethroids, trichlorfon, etc. are all effective. (II) Eliminate egg pods: When killing adults and larvae manually, kill egg pods if they are found. Heat killing is also possible, blocking the cracks can inhibit the hatching of eggs. In addition, indoor cleanliness, especially the removal of various wastes in the kitchen and food storage places, food storage, garbage disposal, etc. are all important measures to eliminate cockroaches. In short, there are many ways to eliminate cockroaches, but the use should be based on the specific situation. It should also be emphasized that the residential area should be carried out in a continuous manner. In public places, repeated pest control can completely eliminate cockroaches. (I) Cockroaches mainly live in the kitchen. All the gaps between the cabinet frame and the wall, the cracks in the wall, and the kitchen drain are their habitats. You can spray insecticides on these places, block the gaps, and scald them with boiling water. (ii) If there are too many cockroaches in the room, it is best to close the doors and windows tightly, and burn 10% of DDT with an alcohol lamp. Burning it for one or two hours can kill a large number of cockroaches. But remember that cockroaches are very strong and sometimes they are just unconscious, not really dead. So they cannot be thrown away as garbage. It is best to scald them with boiling water. Otherwise, many cockroaches will wake up after more than ten minutes, which is equivalent to "letting the tiger go back to the mountain." (iii) Put sticky paper in places where cockroaches often appear. This method has little effect and is equivalent to "waiting for the rabbit by the tree." (iv) Cockroaches should not be swatted or stepped on to death with a fly swatter. It is best to use cockroach paper to stick one by one, which is very accurate and effective. Stepping on it will cause a large number of bacteria and viruses in the cockroach's body to spread everywhere. The cockroach's eggs are protected by thick egg pods. The walls of the cockroach egg pods are hard, with a waterproof layer, a high spine and a breathing tube, and insecticides cannot penetrate. The most effective solution is to use professional equipment, apply knowledge of pest habits, and treat the larvae during their survival period.

Not long ago, foreign researchers also developed a synthetic chemical that can release a special fragrance to induce cockroaches to mate infertilely. In the long run, cockroaches will not be able to reproduce. ★Second Strategy★ Currently, the commonly used effective methods include placing cockroach poison bait, spraying insecticides, applying cockroach-killing chalk, spreading powder, and releasing insecticide smoke, etc., which can be selected according to the actual situation. In addition to the method of killing pests with chemical methods, cockroaches can also be killed by physical methods such as sticky traps and trap bottles. 1. Root cause measures Where the environment is dirty and messy, cockroaches are rampant. Therefore, good hygiene and environmental management are the root causes. To kill cockroaches indoors, we must first maintain good hygiene and remove the conditions where cockroaches live. We must widely carry out activities such as plugging holes and filling gaps and "eight checks" to remove the egg cases and cockroach traces in the cockroach habitat. Cockroach traces refer to insect corpses, remaining limbs, bodies, wings, molting, cockroach feces, and empty egg cases. "Eight checks" refer to: one check of tables, two check of cabinets, three check of chairs, four check of mouths (sewers), five check of pools (washing pools), six check of cases (food processing cutting boards), seven check of seams, and eight check of piles (coal piles, firewood piles, and piles of sundries). Cockroaches like to dig holes and hide in seams. Taking advantage of this habit of pests, you can use putty, cement, or silica gel to plug gaps and caves, leaving no place for cockroaches to hide. For kitchens with severely damaged interior wall structures and old furniture, to eliminate cockroaches, you must thoroughly repair the house and update the furniture. 2. Reasonable spraying of drugs to kill cockroaches Cockroaches often live and hide in cracks and holes. Therefore, when using a sprayer to spray drugs, be sure to spray the cracks, holes, corners, and spray around them. This will have a good spraying effect and save drugs. Cockroaches are reptiles. When spraying drugs to kill cockroaches, do not spray them in the air, nor do you have to spray all four walls. 3. Tips for placing poison baits to kill cockroaches Placing poison baits is a common and simple method to kill cockroaches, but it must be used properly. The trick is "small amount, more points, and a wide range", that is, more poison points in a room, less medicine at each point, and a wider distribution area. In this way, cockroaches can eat the poison bait when they crawl out of their habitats, and the killing effect is obvious. In order to prevent the poison bait from becoming ineffective due to moisture, it is advisable to place the poison erbium particles in the bottle cap. Use chalk containing insecticide to draw on the cockroach activity site. Draw circles or "wells" with a medicine pen around the cracks, holes and corners where cockroaches live and where they often move, so that cockroaches will be poisoned to death when they enter and exit. The painted lines should not be too thin, but should be 2-3 cm thick lines. 4. Don't forget to kill cockroaches when you move to a new house. In recent years, urban buildings have sprung up like mushrooms after rain, and a large number of residents have moved into new houses. Notice to citizens: When you move, please be sure to remove cockroaches and their egg cases hidden in old furniture, clothes, books, paper boxes, and wooden boxes, otherwise, there will be cockroaches in the new house soon. Cockroaches cannot fly, they rely on transportation and luggage, parcels, furniture and other goods to spread, causing regional and even international spread. In addition: 1. Fresh cucumbers drive away cockroaches. Put fresh cucumbers in the food cabinet, and cockroaches will not approach the food cabinet. After the fresh cucumbers are left for two or three days, cut them open and continue to emit the smell of cucumbers, which can also effectively drive away cockroaches. 2. Fresh peach leaves drive away cockroaches. Put the newly picked peach leaves in the place where cockroaches often appear. Cockroaches will stay away when they smell the smell of peach leaves. 3. Onion drives away cockroaches. If you put a plate of sliced ​​onions in the room, cockroaches will immediately flee when they smell the smell, and it can also delay the deterioration of other food in the room. ★Third strategy★ 1. What diseases can cockroaches spread? Cockroaches can carry more than 40 kinds of bacteria that cause disease and poisoning to humans, and can transmit leprosy, plague, dysentery, typhoid fever, pediatric diarrhea and various parasitic diseases. 2. How to remove cockroach habitats? Regularly carry out sanitation and cleaning, remove garbage and discarded debris, find cockroaches and their egg sheaths, and burn them; overnight food should be placed in the refrigerator or covered for protection; turn off the faucet and keep the room dry; in addition, putty should be used to wipe the "three seams" (door seams, wall seams, window seams), block various holes, etc. 3. How to deal with dead cockroaches? The cockroach carcasses and egg sheaths should be burned together. 2. 1. Catch cockroaches with a sugar water bottle. Take 1~2 canned bottles, put 3 spoons of sugar water, add half a bowl of boiling water to dissolve it as bait, and put the bottles where cockroaches are active. After the cockroaches smell the sweet smell, they will crawl into the canned "trap". 2. Catch cockroaches with tung oil. Buy 100~150 grams of tung oil, heat it and boil it into a sticky colloid, apply it around a 15 cm square wooden board or cardboard, put greasy and fragrant food in the middle as bait, and cover other foods to prevent them from stealing food. When cockroaches are foraging, they can be stuck as long as they crawl to the place where there is tung oil. 3. Prepare poison bait to kill cockroaches. Take one part each of borax and flour, a little sugar, mix them well to make bait balls the size of rice grains, and sprinkle them in places where cockroaches are present. Cockroaches will be poisoned to death after eating them, but be sure to pay attention to safety. 4. Fresh cucumbers drive away cockroaches. You can put fresh cucumbers in the food cabinet, and cockroaches will not dare to approach the food cabinet. After the fresh cucumbers are placed for two or three days, cut them open so that they can continue to emit the smell of cucumbers and drive away cockroaches. 5. Fresh peach leaves drive away cockroaches. Put freshly picked peach leaves in places where cockroaches often appear. Cockroaches will stay away when they smell the smell of peach leaves. 6. Onions drive away cockroaches. If you put a plate of chopped onions in the room, cockroaches will immediately flee when they smell the smell, and it can also delay the deterioration of other food in the room.

I found cockroaches at home and tried many methods but nothing worked.
