Cockroaches are omnivorous insects with a wide range of feeding habits. All kinds of food, including bread, rice, cakes, vegetarian and cooked food, melons and fruits, drinks, etc. I especially like to eat fragrant, sweet and oily pasta. Cockroaches love oil. Among all kinds of vegetable oils, sesame oil is the most attractive, and cockroaches are called "oil thieves" in some places. Among sugar, brown sugar and maltose are the most attractive. Cockroaches often eat other things, such as cotton wool products, leather products, paper, books, soap, wires and so on. In outdoor garbage dumps, sewers and toilets, they will eat rotten organic matter and even kill animals. Different kinds of cockroaches also have different feeding habits. Blattella germanica likes to eat fermented food and drink, and likes to drink beer. Periplaneta americana likes to eat rotten organic matter; Periplaneta australis mainly feeds on plants. Water is more important than food for the survival of cockroaches. Cockroaches are thirsty and hungry. They can't drink water for one month and eat for three months (with water). Under the condition of feeding Periplaneta americana dry food without water, the female worm can survive for 40 days and the male worm can survive for 27 days. On the other hand, if there is water and no food, females can live for 90 days and males can live for 43 days. Cockroaches can still live for a week without their heads. The headless cockroach died of thirst because it had no mouth to drink water. When there is no food and water in the harsh environment, cockroaches will kill each other, eat small food and eat weakly, especially insects that have just molted. They can't move and have soft skin, so they become prey for food and absorb water from the corpse to survive.
What do cockroaches like to eat?
Cockroaches are omnivorous insects with a wide variety of foods. All kinds of food, including bread, rice, cakes, vegetarian and cooked food, melons and fruits, drinks, etc. I especially like to eat fragrant, sweet and oily pasta. Cockroaches have the habit of eating oil. Among all kinds of vegetable oils, sesame oil attracts them the most, so some places call them "oil thieves". Among sugar, brown sugar and maltose have the strongest attraction to them.
Besides all kinds of food, cockroaches often eat other things, such as cotton and wool products, leather products, paper, books and soap in houses, warehouses and storerooms. In outdoor garbage dumps, sewers and toilets, they feed on rotten organic matter and even kill animals.
But different kinds of cockroaches have different eating habits. For example, Blattella germanica likes to eat fermented food and drinks, Periplaneta americana likes to eat rotten organic matter, while Periplaneta australis mainly eats plant food and so on.
It is precisely because cockroaches crawl around and eat everything that they pollute and swallow a lot of pathogens. Coupled with their bad habits of eating and pulling, they become mechanical communicators of some pathogens.
Water is more important than food for the survival of cockroaches. Cockroaches can tolerate hunger, but they can't tolerate thirst. As shown in Table 2-3, under the condition that only dry food is provided to Periplaneta americana without water supply, the females can only survive for 40 days and the males can only survive for 27 days. On the other hand, if there is water and no food, females can live for 90 days and males can live for 43 days.
A)27℃, relative humidity 36-40%
When there is no food and water under harsh environmental conditions, cockroaches will kill each other, eat small and weakly, especially insects that have just molted, can't move and have delicate skin, and become prey for food.
What bait do cockroaches like to eat?
There are 0/68 species of cockroaches/kloc-in China, and Blattella germanica (about 15 mm long) is the main pest in the north of the Yangtze River. It is one of the main pests in public places and families. In recent years, cockroaches have been found in shopping malls and hotels in our city and spread rapidly to residential areas. If not controlled in time, they will become a big public hazard, which will directly affect the development of tourism in our city and people's daily life. Cockroaches are greedy. They eat not only food, but also feces and sputum. After eating, some foods often vomit. It can spread dysentery, typhoid fever, cholera, parasites and so on. In addition, cockroaches often bite books, clothes and even leather, and pollute clothes. It can also secrete smelly liquid, leaving a special smell on the food and articles it touches. (1) cockroach control: 1. Artificial killing: kill adults and larvae, clean cabinets and drawers during the day, and kill them as soon as they see them. In places with many cockroaches, such as kitchens, food processing rooms, warehouses, etc., you can turn on the lights every half hour after 8 pm to kill cockroaches. You can get good results. 2. Trapping and killing: use a small glass bottle with a small mouth, coat sesame oil (or sesame oil) around the bottle mouth, put some fragrant food in the bottle, and put it in a place with many cockroaches at night. The cockroach climbed into the bottle and killed it the next morning. The drug ant cockroach ning has an ideal effect of trapping and killing cockroaches. 3, heat killing: cockroaches are not heat-resistant, and die within a few minutes at 60 degrees Celsius. You can pour boiling water into a hidden cockroach and burn it to death. 4. Blockage: For cockroaches hidden in the joints, cement or clay can be used to fill the joints so that they can't climb out and starve to death. 5. Drug killing: cockroach, aerosol insecticide, pyrethroid, trichlorfon, etc. Is effective. (2) Killing eggs and pods: While killing adults and larvae artificially, if eggs and pods are found, kill them. Heat killing can also be used to plug the gap and inhibit the hatching of eggs. In addition, the cleanliness of the room, especially the removal of various wastes in the kitchen and food storage places, food storage, garbage disposal, etc. , are important measures to eliminate cockroaches. In a word, there are many ways to kill cockroaches, but when using them, they should be decided according to the specific situation, and it should also be emphasized that residential areas should be contiguous. It is necessary to kill cockroaches repeatedly in public places. Cockroaches are also called cockroaches and oil thieves. According to experts' research, it has existed in the world for more than 300 million years, even earlier than human beings. It is not only annoying in appearance, but also smelly, and it is a pest that everyone hates. Although it has wings, its flight ability is very poor, mainly by crawling. It eats a wide range of food, not only human excrement such as stool and phlegm, but also human food, especially starch and sugar food. When feeding, just like mosquitoes suck blood, first spit out the secretions in the stomach, and then suck food. Cockroaches carry all kinds of bacteria, viruses and parasite eggs in their mouths (especially in their intestines), and spread diseases by polluting food and utensils. According to scientists' laboratory tests, cockroaches contain more than 40 kinds of pathogenic bacteria such as Salmonella, Shigella, Staphylococcus, Tuberculosis, Pseudomonas aeruginosa and Aspergillus flavus. There are seven kinds of parasitic eggs, such as roundworm, hookworm and hepatitis virus. These bacteria and viruses can live in cockroaches for 12 days and are constantly excreted from feces. Therefore, it is easy to spread dysentery, typhoid fever and hepatitis, causing diarrhea and purulent infection. Cockroaches are nocturnal insects, and they are very fertile. If the climate is mild and moderate, they can breed a nest of 40 to 50 in ten days. 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 to 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 channels of the kitchen. You can spray them with pesticides to plug the gaps and scald them with boiling water. (2) If there are too many cockroaches in the decorated room, it is best to close the doors and windows and burn 10% Didiwei with alcohol lamp. Burning for an hour or two can kill a lot of cockroaches. But remember, cockroaches are extremely vigorous. Sometimes they are just in a coma, but they are 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) Don't be beaten by flies or trampled to death by flies. It is best to stick one to the other with cockroach paper, which is very accurate and effective. Stepping on your feet will spread a lot of germs and viruses everywhere on cockroaches. Cockroach eggs are protected by thick egg pods with hard walls and waterproof layers. ......
What environment do cockroaches like?
How to deal with cockroaches
Cockroaches have 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 annoying, but also protein in their excrement is an important substance causing allergic rhinitis and asthma, especially for children living in crowded rooms and cities.
How to kill 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 leakage, especially in the kitchen.
3. Keep the room clean. In a clean and dry environment, cockroaches will feel unwelcome. After eating, you should seal the food in time, clean the garbage on the ground and in the garbage bag in time, and wash the tableware with hot water first. Dirty tableware will attract the attention of cockroaches. In addition, places such as stoves should also be cleaned regularly.
Use pesticides to kill cockroaches when no one is at home.
Cockroaches are domestic pests, lurking during the day and coming out at night. During the day, cockroaches mostly hide in the corner of the kitchen and the gap in the cupboard, and go out for food at night.
Cockroaches eat almost anything, 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 when eating, making its body dirty, carrying germs, polluting food and spreading 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, almost every household has found the footprints of cockroaches, 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 the wall, and no one is watching.
It is not easy for you to catch cockroaches. At night, you quietly walked into the kitchen, suddenly turned on the light, and saw the cockroach panic and suddenly slipped 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 small pieces between the teeth, which are like vises when crushing hard objects. There are four tentacles and many short hairs on the mouth. Antennas are tools for it to collect food, and short hairs are taste and smell organs with sensory nerves on them, which can eat 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 slightest 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, a small-caliber long-necked glass bottle is used, some sweets are put in the bottle, and sesame oil is coated on the bottle mouth. Cockroaches enter the bottle, and it is difficult to climb out because the bottle wall is very 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 things and get stuck.
Taking advantage of cockroaches' habit of scraping dirt off their backs on hard objects, we scattered some hard and sharp diatomite in the corner of the room. When cockroaches go there to rub their bodies, too much wax oil will be wiped off the surface. Therefore, a large amount of water in cockroaches will be lost and dehydrated to death.
You can also put out a cockroach by interfering with its sense of external vibration. For example, as soon as you see a cockroach, you can make a hissing sound with your mouth immediately, and then pat it quickly, which makes it easier to kill it.
Chemical drugs can also be used against cockroaches, and there are five thousandths of dichlorvos, or three thousandths of deltamethrin and boric acid powder. You can spray cockroaches where they live and move, or put a few pieces of cockroaches to kill them. There is a pyrethroid insecticide called "Killing Cockroaches", which has been tried in the kitchens of cargo ships, oil tankers and Yangtze River passenger ships of the Maritime Safety Administration. When 300 ml of liquid medicine was sprayed in the cabin of 60 cubic meters, the cockroach immediately became excited and excited, climbed out and fell to the ground and died. Some are unconscious and immortal. ......

It is precisely because cockroaches crawl around and eat everything that they pollute and swallow a lot of pathogens. Coupled with their bad habits of eating and pulling, they become mechanical communicators of some pathogens.
Methods of Killing Cockroaches Types of drugs for killing cockroaches According to the principle of killing cockroaches and the mode of administration, drugs for killing cockroaches are divided into the following categories:
(a) contact killing, through drug spraying or smoke fumigation, so that drugs reach the surface of cockroaches-rely on drug contact with cockroaches to kill cockroaches. The main products of contact killing are:
(1) pyrethroid spray, whose representative products are radar, mirex, etc. These products first entered the market and have been widely used or abused for more than 20 years. Cockroaches are strongly resistant to them, but they are basically ineffective against Blattella germanica (a small cockroach);
② Insecticide powder, 0.09% synergistic bendazole, 5% malathion, 1% propoxur powder, etc.
(3) cockroach smoke, smoke generated by physical methods, is used as a carrier to transport drugs to all corners to achieve the purpose of killing cockroaches, such as cockroach smoke bombs.
(2) Poisoning, that is, cockroach killing drugs are mixed with poison bait, attractant, preservative, etc. Make poisonous bait that cockroaches like to eat according to a certain proportion to kill cockroaches. The main products that cause death by feeding poison are:
① Cockroach-killing granules, cockroach-killing drugs and poison bait are mixed, granulated and dried, which are mainly used for ground scattering in cockroach environment;
② gel bait for killing cockroaches, wet paste poison bait, including syringe, patch and water gel bait. Among them, water gel bait is a special cockroach killing drug just made in China, which has long-lasting efficacy, convenient use and low price, and is gradually loved by ordinary people.
(3) Biological cockroach killing adopts an environmentally friendly way that is harmless to human beings. The main varieties are:
① Killing cockroaches by using different characteristics that different organisms (species) can't adapt to, leading to cannibalism and hunger strike death of cockroaches. China's "Lang Ping 1" is the only product of this kind;
(2) Use cockroach virus to create cockroach plague to kill cockroaches. Domestic Poisonous Island is the only product of this kind.
The above are typical and practical varieties of cockroach medicine, and a few varieties are omitted because of the limitation of effect or use occasion.
Although the following does not belong to the category of cockroach medicine, its function is similar to that of cockroach medicine, and it is also briefly explained.
① Cockroach trap: lure cockroaches into a set trap, and then kill them, such as Uncle Cao's cockroach jar and cockroach house.
(2) Ultrasonic cockroach killing has gradually faded out of the market because of its poor effect and low dosage of ultrasonic radiation. ...
What food do cockroaches like? Put it in a cockroach, I don't know what to put,
You can find "Tianjin cockroach" on Taobao, and you will find us. We are a company specializing in killing cockroaches, ants and pests. I'm the shopkeeper. ~!
Accept it
Do you know what cockroaches like best? This kind of thing is definitely more attractive and can make cockroaches choose this kind of thing. I have made up my mind.
Cockroach traps have quietly become popular. Water bottle+newspaper+shoe box = cockroach trap artifact
Manufacturing process of cockroach catching artifact
A newspaper, a shoe box, a mineral water bottle and a small amount of food.
② Cut off the top of the mineral water bottle and put the food in the bottle. The newspaper was folded in half, rolled into a trumpet and stuffed into a mineral water bottle.
③ Dig a hole with the same size as the mineral water bottle near the bottom of the shoe box. Stuff two thirds of the bottle in. Cover the shoe box to make it light-tight.
(See the screenshot above)
Are you troubled by the endless "Xiao Qiang" at home in the hot summer? Recently, an artifact for catching cockroaches has been quietly circulated on the Internet. You can successfully catch annoying cockroaches at home by using discarded mineral water bottles, shoe boxes and waste newspapers. Is this method effective? The reporter conducted an experiment yesterday. The results show that the artifact is reliable, but attention should be paid to the details when operating. Experts also pointed out that this artificial product does take advantage of the characteristics that cockroaches like darkness and humidity.
Experiment: The cockroach trap artifact is really effective.
According to the production method circulating on the Internet, the reporter prepared a newspaper, a shoe box and a mineral water bottle the night before, and prepared bread crumbs, ham and other "bait" to attract cockroaches, and then began to make this cockroach-catching artifact: first, cut off the top of the mineral water bottle neatly, roll the newspaper into a trumpet and stuff it into the mineral water bottle; Seal the newspaper and bottle with adhesive tape, and block the gap between the newspaper and the bottle mouth; Then, dig a hole with the same size as the mineral water bottle on the side near the bottom of the shoe box, put two-thirds of the bottle in and leave one-third outside. The edge of the paper tube covers the ground, then the shoe box is closed tightly to make it opaque, and it is placed in the place where cockroaches often appear.
After a night of waiting, yesterday morning, the reporter opened the shoe box and found that there were many cockroaches in the empty mineral water bottle, but it was far from the magical effect of catching dozens or even dozens of cockroaches in one night circulated on the Internet.
Disclaimer: Take advantage of the dark and humid characteristics of cockroaches.
Why can the cockroach catching artifact really catch cockroaches? The relevant person in charge of the Ivy Office in Changsha said that this method mainly takes advantage of the characteristics that cockroaches like dark, warm and humid environment, often hide in cracks and holes, and like to eat starchy food, especially sweet or greasy food. Cockroaches are most active at night. "Because of the cover of the newspaper, the shoe box of the homemade cockroach catcher is black, which is similar to the hidden corner where cockroaches usually live. After the cockroach's favorite food is put in, the cockroach will crawl in along the newspaper when it smells the food. "
"It is worth noting that the shorter the newspaper that captures cockroach cultural relics, the better. The farther the bait is from the entrance, the weaker the effect of attracting cockroaches by the taste of food. " The person in charge also pointed out that theoretically, this method is more suitable for places with more cockroaches, such as restaurants, and the effect is relatively poor in places with fewer cockroaches, such as homes. But generally speaking, there are cockroaches hiding in secret corners where cockroaches haunt. Therefore, it is suggested that drugs should be used scientifically and reasonably to kill cockroaches. According to the principle of comprehensive prevention and classified guidance, general units and families should use cockroach killing medicine pens (blocks) and cockroach killing glue bait (granules); In key industries and key parts, spray liquid should be used to spray on the surface of objects (walls), supplemented by rubber bait (particles) to kill cockroaches; External environment (sewer, ditch, garbage passage, etc.). ) cockroach bombs or hot smoke should be used for fumigation.
Reminder: Don't pat a cockroach after you catch it.
According to the statistics of Changsha Center for Disease Control and Prevention, cockroaches are active all year round in Changsha, and the density began to increase linearly in April, reaching a peak in July, and then decreased month by month.
"Once you catch cockroaches with a cockroach trap, don't shoot them, because shooting cockroaches with slippers is not complete. The bacteria after cockroach death may not only bring secondary pollution, but also kill cockroach eggs. The best way to kill cockroaches is to burn them. " The relevant person in charge of Ivy's office reminded that cockroach prevention and control should focus on strengthening the management of cockroach breeding grounds and removing garbage and sundries, which should be cleaned up every day.
At present, Changsha is carrying out centralized cockroach killing operations in summer and autumn. According to the deployment, before September 30, all districts in the city will complete two rounds of indoor cockroach killing and dosing, sewer hot smoke fumigation, cockroach breeding and habitat management, and improve cockroach control facilities; Complete density monitoring after cockroach killing before September 30.

What flavor do cockroaches like?
I like sweetness, and the smell of vegetable oil will also attract cockroaches. Once I opened an empty oil pot and forgot to cover it. Who knows that five or six cockroaches got in the next day, because the bottle wall was so slippery that cockroaches couldn't get in or out. A few days later, more than 20 cockroaches were loaded. So, I have another way to kill cockroaches.
What food do cockroaches like best?
Cockroaches are omnivores. They only eat organic matter. They can eat more than 3700 kinds of organic matter.
