What are the dangers of cockroaches? What are the dangers of cockroaches?

Cockroaches are very harmful to the human body, such as the following: 1. It can spread germs. Cockroaches can carry bacterial, viral, pathogenic microorganisms, such as Yersinia pestis, dysentery bacillus or measles bacillus.

2. If cockroaches crawl on a person's body and bite a person, it will infect the human body through the transmission of bodily fluids. 3. Cockroaches can also pollute the environment, and the feces of cockroaches will be contaminated on the food that crawls over, so that if they are eaten by people, they will spread serious infectious diseases through the fecal-oral route. 4. Cockroaches can also cause electrical appliances to malfunction, because cockroaches will have the habit of gnawing, so chargers and electrical equipment will leakage and other serious situations due to cockroach bites.

The main harm of cockroaches to humans: Cockroaches are second only to houseflies and can sometimes be more annoying. It not only spreads diseases but also causes allergic reactions in people, such as allergic asthma, dermatitis, etc.

It crawls everywhere on food, gnaws on clothes, calligraphy and paintings, and everywhere it appears. Cockroaches can spread diseases: Cockroaches have been shown to carry about 40-50 species of bacteria that are pathogenic to vertebrates, such as dysentery bacillus, E. coli, Yersinia pestis, etc., which can cause food poisoning and spread pathogenic bacteria such as hepatitis, polio, pneumonia, tuberculosis, etc.

It is also an intermediate host of a variety of parasites, which can carry a variety of worm eggs such as roundworms, tapeworms, pinworms, whipworms, etc., and also carries a variety of protozoa, four of which are pathogenic to humans or animals, such as dysentery amoeba and so on. Cockroach control through environmental management: Regular sanitation cleaning.

Remove and reduce food sources and habitats for cockroaches. Remove food residues from the kitchen and wash or boil water to scald cabinets, utensils, etc. Remove cockroach traces (cockroach droppings) and habitats.

Plugging holes and wiping cracks. Common methods to kill cockroaches: Poison bait:

Cockroach poison bait has the advantages of safety, high efficiency, less environmental pollution and easy to use. When using, follow the principle of "less and more", place the poison bait in a moisture barrier, and focus on the corners of cabinets or drawers in kitchens, dining rooms, etc., on the cracks behind furniture, wires and pipes, or directly in the habitat of cockroaches. Retention spraying:

Spraying long-acting insecticides on key places where cockroaches often inhabit and move, such as crevices, holes, wall kick angles, corners and hidden places of fixed equipment, can cause cockroaches to come out of contact with drugs and die of poisoning. It is necessary to avoid spraying floors, walls and ceilings indiscriminately and on a large scale to avoid wasting and contaminating the drug. Thermal smoke method:

It is a high-efficiency, effective pesticide application method, can quickly reduce the density of cockroaches in a short time, its principle is to heat and vaporize the special hot smoke insecticide under the action of the hot smoke machine, and condense into a fine mist, suspended in the air in the form of smoke evenly diffused in the room, penetrate into the corners of the crevices, so that the cockroach touches the medicine and excitedly crawls out of the burrow, and finally dies. The smoke blower must be used in conjunction with the hot fog. Special attention should be paid to the use of insecticides, which are registered by the state for sanitary use and allowed for indoor use, and must not be used for indoor cockroach extermination with general pesticides.

A fertilized female cockroach produces a large number of egg sheaths in her lifetime, and the American cockroach can produce more than 50 at most, so the cockroach has strong fecundity. Every 7-10 days, a mature female cockroach can produce an egg sheath containing 14-40 eggs, which are colloidal and hatch between 20 and 37. The higher the temperature, the shorter the incubation time, at a constant temperature of 30, it only takes 20-30 days, and the longer can exceed three months.

A female cockroach can reproduce nearly 10,000 offspring a year, up to 100,000.

Under normal circumstances, the cockroach egg sheath will be carried by the female cockroach on the tail until hatching, and if the cockroach egg sheath is not protected by the female cockroach, the egg sheath falls off prematurely, and the eggs inside may not hatch. The cockroach eggs are large, white at first, and then slowly turn black, like a melon seed, and the shell is hard, and can only be burned by fire or boiling water. They like to be in the cabinet or in a longer, humid place, such as a place under the refrigerator where there is a certain temperature.

Especially in the cracks of the worn-out sofas.

But cockroaches have the characteristics of migration, for example, if your home has been extinguished, there are no cockroaches, and when the neighbor exterminates the cockroaches, some adults may come to your house to "live". Therefore, "strict prevention" is also the key. "Plugging holes and wiping cracks" is the key, and you should be extra careful when moving, the eggs of cockroaches are laid in the egg sheath, and there will be more than 40 eggs at most in the egg sheath of a black-breasted cockroach.

The egg sheath is a bit like a pod and is the same color as a cockroach. These egg sheath sprays can't be killed! Be sure to use boiling water or fire to burn it.

The cockroach extermination company told everyone that egg sheaths are generally laid by cockroaches in the side seams of drawers and in the crevices of cardboard boxes. If we want to eliminate cockroach egg sheaths, we need to use the following two methods to use regular cockroach extermination drugs to deploy cockroach medicine to the area where cockroaches are active at any time, forming a protective belt to isolate cockroaches in this area, even if small cockroaches are born, they can be eliminated.

Cockroaches no matter from the **, it eventually sits into a big nest, the main reason comes from the sanitary conditions at home, if the garbage and stove at home can not be cleaned up at any time, it will eventually become an excellent place to nourish cockroaches. This cleaning can not be an ordinary cleaning, the home must be spotless, there must be no food exposed to the outside, any nail to eat the residue, will attract cockroaches.

The hazards of cockroaches are:Danger to health and damage to property

1. Endangering health

Cockroaches have the habit of eating, spitting and excreting, and secrete odorous liquid, in their activities, not only can carry more than 40 kinds of pathogens such as mycobacterium leprae, Yersinia pestis, Shigella dysenterybacterium, etc., but also an important vector of intestinal diseases and parasitic diseases, and their secretions and feces contain a variety of carcinogens.

Hiding in dark corners such as kitchens and bathrooms that are not easy for people to notice not only endanger storage items such as grain, oil, food, clothing, and books, but also spread diseases and cause harm to people.

2. Damage to property

Cockroaches eat everything, and food at home can be tainted by cockroach bites, resulting in economic losses, and cockroaches can easily drill into household appliances such as electrical appliances and electronic computers to bite and break the line, or create a short circuit, causing unexpected failures. Nowadays, more and more families, especially the failure of kitchen appliances, are related to cockroaches, such as microwave ovens, induction cookers, etc., which cause taboo losses to families to a certain extent.

Cockroaches can be infected with bacteria that cause diseases such as cholera, pneumonia, diphtheria, meliardosis, anthrax and tuberculosis in Asia.

It can carry a variety of worm eggs such as roundworms, duodenal hookworms, beef tapeworms, windworms, whipworms, etc.

They can also serve as intermediate hosts for a variety of nematodes, such as Candida candida, Hymenola brevis, and tumor tubes.

It can also carry a variety of protozoa, of which 4 species are pathogenic to humans or animals, such as dysentery amima, Giardia enterus, etc. Experimental studies have confirmed that cockroaches can carry and excrete viruses, including coxsackievirus, poliovirus, etc.

Cockroaches carry bacteria, and food contaminated by cockroaches may have adverse reactions when eaten by humans. It is a carrier of infectious bacteria and viruses, an intermediate host of a variety of parasites, and carries a variety of protozoa. Cockroaches can also infeste household appliances and instruments everywhere, causing short-circuit damage to equipment, and can also drill into human ears to cause ear diseases.

Everyone knows that cockroaches are extremely harmful creatures, and they can't be wiped out and annoying, so do you know what harm cockroaches are?

The main hazards of cockroaches are as follows. The most dangerous of the pathogens carried by cockroaches are Mycobacterium leprae, which infects leprosy, Murine bacillus that infects bubonic plague, and Bacillus paradysentery, which causes diarrhea in children.

Second, cockroaches can bite, and there is a possibility of infection with the virus after cockroaches bite. Third, polluting the environment, cockroaches have the habit of eating and pulling, carrying a large number of parasites, and things crawling over by cockroaches may be polluted, which will cause people to have stomach aches and diarrhea. Fourth, when the electrical appliance fails, the cockroach eats almost everything, because of the cockroach's gnawing habit, which leads to the failure and short circuit of communication equipment, computers, etc.

Cockroaches prefer to choose warm, moist, abundant food and crevices to live, which are the 4 basic conditions they need to breed. All buildings where people live and live generally have these conditions, so cockroaches have become a sanitary pest that infests thousands of households. Warmth and love tide is an important habit of cockroaches.

It is not difficult to find that whether it is in a restaurant, a home, a train or a ship, the kitchen is always the most invasive. Even in the kitchen, they generally like to live near stoves and sinks. Like the dark and afraid of light, day and night, this is also an important habit of cockroaches.

Dangers of cockroaches:contaminated food; transmission of bacteria and viruses; damaged items; causing an allergic reaction in a person; Causing electrical malfunction.

1. Contaminated food: Cockroaches have the habit of spitting while eating, and carry a lot of pathogenic bacteria on their bodies, so it is not recommended to eat as long as it is a place or food where cockroaches crawl.

2. Transmission of bacteria and viruses: cockroaches can carry more than 40 kinds of bacteria and viruses that cause disease to vertebrates, such as dysentery bacillus, salmonella, hepatitis B virus and parasite eggs and other pathogens. Cockroaches crawling everywhere will mechanically spread these germs, endangering people's health.

3. Damaged items: The chewing mouthparts of cockroaches can gnaw on items and damage organic items such as clothes and books.

4. Allergic reactions: Cockroach secretions, excrements, vomit, bacteria carried on the body surface of cockroaches, parasite eggs and cockroach corpse powder will cause allergic reactions after human contact.

5. Cause electrical failure: cockroaches will bite the wires of various electrical appliances and cause equipment failure, and will also infringe on communication equipment, computers, etc., resulting in failures.
