Why are cockroaches so big in Guangdong?

Years of experience in killing cockroaches show that no matter where cockroaches come from, the main reason is the sanitary conditions at home. If the garbage and stove at home cannot be cleaned at any time, it will eventually become an excellent place to nourish cockroaches. This cleaning cannot be ordinary cleaning. It requires the house to be spotless. No food is allowed to be exposed. Anything left over will attract cockroaches. So there are only two places where cockroaches have never been found, the military student dormitory and the Buddhist temple where nuns live. There won't be cockroaches in these two places, because they won't have anything to eat, and they have been cleaned like nitpicking. When the author lived in a military school, the crazy and harsh military health appraisal led to the spotless deepest part under the bed, and cockroaches naturally had no basis for survival. As for the nun meditation hall, the walls are washed, women are diligent in cleaning, and cockroaches have no basis for survival. In addition, other inhabited places also have cockroach parasitic conditions. 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. One. 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 our dormitory, and the number of cockroaches in China didn't decrease until one day the rats next door came to visit and settled in a shoe box under the bed. 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. Two. 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. 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? First, carefully check sewers, cracks in walls, floor partitions and windows to prevent cockroaches from entering. Second, keep the room dry. Cockroaches live in a humid environment, so be careful not to have any leaks, especially in the kitchen. 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. Fourth, kill cockroaches with pesticides when no one is in the house. 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 when eating, making it dirty, carrying germs, polluting food, and spreading various diseases, such as paratyphoid fever, dysentery, tuberculosis and China hepatitis. Cockroaches are very old insects with a history of more than 320 million years. Carboniferous cockroach fossils are almost the same in appearance as 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 receptor, which can sense which direction the external stimulus comes from and thus 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. Some people are unconscious and die a day later, and some tenacious people can't live for five days. Recently, scientists at the National Institute of Genetics in Japan found that toad (commonly known as toad) is a natural death of cockroaches. Cockroaches were once rampant in the small animal breeding room of this institute, which made people feel at a loss. Later, some toads were raised in the breeding house, and soon the cockroaches disappeared. After dissection, it was found that most of toad's stomach was the remains of cockroaches. A scientist in Kansas, USA, has developed a sexual taste trap for trapping and killing male cockroaches, which is mainly a toxic and odorous sticky paper. This smell is exactly the same as the smell of sex pheromones secreted by female cockroaches, which can lure male cockroaches to poison the sticky flypaper. As long as there is a little bit of this sex pheromone, then the male cockroach within eight meters can jump into this trap in five seconds. Dutch scientists have also synthesized a similar sex pheromone. This shows that the eradication of cockroaches is not far off. One day, people will use these ideal methods to make cockroaches that endanger human health "childless". Not long ago, foreign researchers also developed a synthetic chemical, which can release a special fragrance and induce cockroaches to mate infertile. In this way, cockroaches can't carry on the family line. Cockroach control: First, artificial killing: kill adults and larvae, clean cabinets and drawers during the day, and kill them when you 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. , so you can get good results. 2. Trapping and killing method: use a small glass bottle with a small mouth, put sesame oil (or sesame oil) around the bottle mouth, put some fragrant food in the bottle, put it in a place where there are many cockroaches at night, and the cockroaches climb into the bottle and kill it the next morning. The drug ant cockroach ning has an ideal effect of trapping and killing cockroaches. Third, heat killing: cockroaches are not heat-resistant, and they die in a few minutes at 0 degrees Celsius on land. Boiling water can be poured into the hidden cockroaches and burned to death. 4. Blocking: For cockroaches hidden in the cracks, cement or soil can be used to block the cracks so that they can't climb out and starve to death. 5. Drug killing: ants and cockroaches, insecticide aerosol, 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 all kinds of garbage in the kitchen and food storage places, food storage, garbage disposal, etc. , are important measures to eliminate cockroaches. In short, there are many ways to kill cockroaches, but in use, it should be decided according to the specific situation, and it should also be emphasized that residential areas should be contiguous. In public places, cockroaches can only be completely eliminated after repeated eradication. (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 is best to close the doors and windows and light 0% drops with alcohol lamp. 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. Cockroach eggs are protected by thick egg pods, which have hard walls, waterproof layers, high spines and breathing tubes, and pesticides cannot penetrate. The most effective solution is to use professional equipment and pest habit knowledge to treat its larvae for the second time to kill them.
