What cockroaches infect, how contagious cockroaches are

The body surface and digestive tract of cockroaches can carry a variety of pathogenic microorganisms, such as dysentery bacillus, salmonella, staphylococcus, Escherichia coli, hepatitis virus, parasite eggs, etc., when these cockroaches with pathogens crawl on food and tableware, they may transmit pathogens to humans. Cockroach secretions, excretions, and vomit can also cause allergic reactions in the human body.

Hello, happy to answer your questions.

Cockroaches carry many infectious disease pathogens and viruses on their feet, on the surface of their bodies and inside them, including plague, cholera, typhoid, dysentery, tuberculosis, pneumonia, polio and a variety of peculiar worms such as hookworms, roundworms and pinworms, which are among the leading causes of the spread of diseases.

Cockroaches can often transmit a variety of diseases. Cockroaches can carry pathogenic bacteria, viruses, fungi and parasite eggs, and can be used as an intermediate host for a variety of parasites. Cockroaches can transmit dysentery bacillus, Escherichia coli, Mycobacterium tuberculosis, and other bacteria to cause a variety of bacterial infectious diseases such as respiratory tract and gastrointestinal tract.

Be. 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, Shiga missing bindenal hook nematodes, 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.

The main characteristics of cockroaches are manifested in the following aspects: 1. Food Cockroaches eat more widely than many people imagine, which is also a key factor for cockroaches to survive from ancient times to the present. From put's food to the brushes used to wash clothes, almost all the substances in the human habitation range can be used as their food Zenkai, such as:

Wires are glued to the edge of the leather, a piece of wooden furniture.

1. Cockroaches eat almost everything. For example, all kinds of food, garbage, feces, dead animals, clothes, books, fur, etc., when there is a shortage of food, eat the corpses and excrement of their companions, and even eat their own kind. Extremely survivable!

2. Cockroaches can run three miles per hour. Able to fly, can climb walls, and is good at drilling holes. Diurnal and nocturnal, the sense of touch and smell is very sensitive, and when encountering danger, it is difficult to catch it. Protection!

3. Cockroaches can burrow into coin-sized seams (about millimeters thick), and male adults can burrow into millimeter seams. Female cockroaches with eggs need a place a millimeter or two coins thick to hide. Hiding Kung Fu is strong!

4. Cockroaches reproduce very quickly, and a pair of cockroaches can reproduce 20,000 after one year. Female cockroaches generally mate once in their lifetime, and each mating time is up to 2 hours, and they can reproduce for life, or even vegetatively. Strong reproduction!

5. Cockroaches can lay more than 4-50 egg sheaths in their lifetime. One egg sheath can hatch about 40 small cockroaches. The eggs of cockroaches are protected by a thick egg sheath, which cannot be penetrated by ordinary insecticides, and can only be killed again after they hatch.

This is also one of the reasons why cockroaches have been extinguished for a long time. Strong self-protection ability!

6. At present, cockroaches are undoubtedly the first of the four pests in terms of the degree of harm caused by flies, mosquitoes, cockroaches and rats to urban humans. It emerges day and night, cannot be seen or caught, reproduces quickly and is harmful, and has become a prevention and control problem in most cities in the world. The Beijing Center for Disease Control and Prevention investigated the infestation of cockroaches in the city.

At present, more than 45 households, 86 hospitals, and 98 hotels and restaurants in Beijing have been invaded by cockroaches. Aggressive!

7. It feeds and crawls everywhere. It eats a variety of foods: garbage, excrement, and food; Wide range of infringements:

Garbage, toilets, kitchens, and restaurants can be found, and cabinets, containers, and food can be climbed. Cockroaches are full of bacteria all over their bodies, and the bad habit of cockroaches is to eat, crawl, and excrete at the same time, walking all the way and pulling all the way, spreading bacteria everywhere, and cockroaches are one of the main culprits of spreading diseases. Strong ability to spread germs!

Cockroaches have been shown to carry about 40-50 species of bacteria that are pathogenic to vertebrates, such as dysentery bacillus, Escherichia coli, Yersinia pestis, etc., which can cause food poisoning and spread hepatitis, poliomyelitis, pneumonia, tuberculosis and other pathogenic bacteria.

Cockroaches have been medically proven to carry the eggs of disease-causing bacteria, viruses, fungi as well as parasitic worms, and can serve as intermediate hosts for many types of worms. It is a carrier of infectious bacteria and viruses, because of the food everywhere, crawling, wide range of infestation, and miscellaneous food, it can be used in garbage, toilets, washrooms, and food, and if you eat food contaminated by cockroaches, you may transmit diseases. It is mentioned in many literatures that cockroach feces contain carcinogens.

Many types of food are eaten and contaminated by humans, spreading diseases such as dysentery, typhoid, roundworms, pinworms, etc.

They mostly inhabit kitchens, canteens, warehouses, etc., and damage food, clothing, books, etc.

Cockroaches transmit a variety of diseases such as dysentery, paracholera, hepatitis, tuberculosis, diphtheria, ascariasis.

Cockroaches can transmit a variety of diseases, cockroaches can carry pathogenic bacteria, viruses, fungi and parasite eggs, and can be used as an intermediate host for a variety of parasites, even the feces of cockroaches also contain carcinogens, and the harm is many. Cockroaches can transmit dysentery bacillus, Escherichia coli, Mycobacterium tuberculosis, Bacillus anthracis, typhoid bacillus and other bacteria, causing a variety of bacterial infectious diseases such as respiratory tract and gastrointestinal tract. Cockroaches can also carry Sarkozy virus, poliovirus, hepatitis virus, etc., causing various viral infectious diseases.

In addition, cockroaches can also transmit parasitic diseases such as taeniasis, hookworm disease, and roundworm disease.

Mosquitoes can transmit diseases such as malaria, Japanese encephalitis, dengue fever, etc. It is necessary to do a good job in environmental sanitation and eliminate mosquito breeding grounds. According to the situation, screen doors, window screens, mosquito nets, mosquito coils, insecticides and other mosquito prevention and control products are selected to prevent mosquito bites.

Flies can transmit diseases such as cholera, dysentery, typhoid, etc.

The effective way to control flies is to deal with the breeding environment of flies, such as garbage bagging (the bag should be intact and not broken, and the bag mouth should be tightened), no littering, no open defecation, and handling pet feces. Take care of your food to prevent flies from crawling. To kill flies, you can use fly swatters, fly killer lights, sticky fly paper (belts, ropes), etc.

Rats can transmit a variety of diseases such as plague, epidemic hemorrhagic fever, leptospirosis, etc. It is necessary to do a good job of environmental sanitation and reduce the hiding places of rats; Store your food to reduce contamination by rats. Rats can be captured and killed with rat traps, rat cages, sticky rat boards and other rat trapping tools, and safe and efficient drugs can also be used to kill rats.

It is necessary to pay attention to the storage and use of rodenticide drugs to prevent human and animal poisoning.

Cockroaches can transmit a variety of diseases such as dysentery and typhoid, and the proteins in their excretion can cause allergic rhinitis and asthma. Cockroaches mostly live in humid environments, so keeping the room dry and clean can reduce the breeding of cockroaches. After eating, the food should be stored in an airtight manner, the tableware should be rinsed with hot water, the stove and other places should be kept clean, and the garbage on the ground and in the garbage bag should be cleaned up in time.

Cockroaches can be killed using drugs or cockroach sticky plates.
