★ The first raiders ★ How to deal with cockroaches has existed for more than 300 million years. Most of them grow in warm and humid environments and are everywhere 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 remove 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 receptor, which can sense the direction of external stimuli 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 people are unconscious and die a day later, and some tenacious people can't live for five days. Recently, scientists at Japan's National Institute of Genetics discovered that toads (commonly known as toads) are natural deaths of cockroaches. Cockroaches were once rampant in the small animal breeding room of this institute, and people were at a loss. Later, some toads were kept in the breeding room, 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, invented a sex-smell trap to trap and kill male cockroaches. This trap is mainly a poisonous sticky paper with smell. This smell is exactly the same as the smell of sex pheromone secreted by female cockroaches, which can attract male cockroaches to be poisoned on sticky mousetrap paper. With a little bit of this sex pheromone, a 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 it is not far away to eliminate cockroaches. One day, people will generally use these ideal methods to make cockroaches that endanger human health "childless". Not long ago, foreign researchers also developed a synthetic chemical that can release a special fragrance and induce cockroaches to mate aseptically. If this situation continues, cockroaches will not be able to carry on the family line. ★ Second Raiders ★ Now the commonly used effective methods are putting cockroach poison bait, spraying insecticide, smearing cockroach chalk, dusting powder, spraying insecticidal smoke, etc. , and choose to use according to the actual situation. In addition to chemical methods to kill pests, cockroaches can also be trapped and killed by physical methods such as sticky traps and traps. 1, radical measures Where environmental sanitation is messy, cockroaches are rampant. Therefore, it is a fundamental measure to improve the health and management environment. To kill cockroaches indoors, we must first do a good job in hygiene, eliminate the habitat conditions of cockroaches, and extensively carry out the activities of plugging holes and plastering seams and "eight inspections" to remove the egg sheaths and cockroaches from their habitats. Cockroach marks refer to insect carcasses, residual limbs, corpses, wings, molting, cockroach excrement, empty egg sheaths, etc. "Eight inspection" refers to: the first inspection platform, the second inspection cabinet, the third inspection chair, the fourth inspection port (sewer port), the fifth inspection pool (washing pool), the sixth inspection box (food processing board), the seventh inspection seam and the eighth inspection pile (coal pile, firewood pile and sundries pile). Cockroaches like to drill holes and hide cracks. By taking advantage of the living habits of pests, you can block gaps and caves with putty, cement or silica gel, so that cockroaches have nowhere to hide. For those kitchens with severely damaged interior walls and outdated furniture, houses must be completely repaired and furniture updated to eliminate cockroaches. 2, reasonable spraying cockroaches often drill cracks and holes to hide, so when using a sprayer to spray drugs, it must be sprayed around cracks, holes and corners, so that the spraying effect is good and the drugs are saved. Cockroaches are reptiles, so don't spray them into the space and don't wear masks. Spray around. 3. The trick of putting poison bait to kill cockroaches is a common and simple method, but if it is used properly, the trick is "fewer in number, more in number and wider in area", that is, putting more poison spots in a room, with less consumption of each spot and wider distribution area. In this way, cockroaches can eat poison bait when they climb out of their habitat, and the killing effect is obvious. In order to prevent the bait from losing its efficacy due to moisture, it is suggested to put the poison erbium particles in the bottle cap. Use dusting powder containing pesticides in cockroach activity places. Around the crevices, holes and corners where cockroaches inhabit and often move, the word "well" is used to poison cockroaches with powder marks painted when they enter and leave. Don't draw the road too thin, it should be a thick line of 2-3 cm. 4, move to a new home, don't forget to kill cockroaches In recent years, urban buildings have sprung up like mushrooms after rain, and a large number of residents have moved into new homes. Warning to the public: When moving, please be sure to remove cockroaches and their egg sheaths hidden in old furniture, clothes, books, cartons and wooden cases, otherwise there will be cockroaches in the new house soon. Cockroaches can't fly They spread through transportation and goods such as luggage, parcels and furniture, which leads to regional and even international spread. Also: 1. Fresh cucumbers can 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 can drive away cockroaches. Put the newly picked peach leaves in places frequented by cockroaches, and cockroaches will avoid them when they smell the peach leaves. Onions can drive away cockroaches. If you put a plate of sliced onions indoors, cockroaches will run away as soon as they smell it, and at the same time, they can delay the deterioration of other food indoors. ★ The third strategy ★ 1. 1. What diseases can cockroaches spread? Cockroaches can carry more than 40 kinds of pathogenic and toxic bacteria, and can be infected with leprosy, plague, dysentery, typhoid fever, infantile diarrhea and many parasitic diseases. 2. How to clear the cockroach habitat? Clean regularly, remove garbage and discarded sundries, find cockroaches and their egg sheaths, and burn them; Overnight food should be put in the refrigerator or covered with protection; Turn off the tap and keep the room dry; In addition, putty should be used to wipe the "three cracks" (cracks in doors, walls and windows) and block all kinds of holes. 3. What should I do with dead cockroaches? Cockroach carcasses and egg sheaths should be burned collectively. Second, 1. Take 1~2 canned cockroaches in syrup bottles, add 3 spoonfuls of sugar water and add boiling water to make bait. Put the bottle where the cockroach is active, and the cockroach will climb into the "trap" after smelling the sweetness. 2. tung oil catches cockroaches 100~ 150. Spread it around a 15cm square board or cardboard, put greasy and fragrant food as bait in the middle, and cover other foods to avoid stealing. When cockroaches feed, they can be stuck as long as they climb to the place with tung oil. 3. Mix poison bait to kill cockroaches, take borax, flour, and a little sugar, mix well to make poison bait pills with rice grains, and scatter them in places where cockroaches haunt and eat them immediately. Fresh cucumber can drive away cockroaches. You can put fresh cucumbers in the cupboard, and cockroaches are afraid to go near the cupboard. After two or three days, cut the fresh cucumber to make it continue to emit the smell of cucumber and drive away cockroaches. Fresh peach leaves can drive away cockroaches. Put the newly picked peach leaves in places frequented by cockroaches, and cockroaches will stay away when they smell the peach leaves. 6. Onions can drive away cockroaches. If you put a plate of chopped onions indoors, cockroaches will run away as soon as they smell it, and at the same time, they can delay the deterioration of other food indoors.
