Flies easily penetrate a person's home and greatly annoy him with their omnipresence. Insect paws end with claws and sticky pads. Thanks to them, flies move on various surfaces. Insect saliva contains enzymes that liquefy solid food. They feed on decaying organic residues and human food.
Instructions
Step 1
In addition to the fact that flies are very annoying with their presence, they also carry various dangerous diseases. Infection of a person can occur after he eats an infected product on which the fly was sitting. As a result, there is a possibility of impaired functioning of the liver and organs of the gastrointestinal tract, constipation, diarrhea and high fever.
Step 2
The category of infectious diseases includes ailments caused by the ingestion of pathogenic bacteria that release exotoxins, which lead to poisoning. Some diseases have an incubation period that can last from several hours to several years.
Step 3
The fly is capable of carrying approximately 6 million bacteria on its body and about 28 million within itself. In addition, insects carry particles of feces that remain on food when the fly lands on them.
Step 4
During its life span, the fly lays about 500 eggs, and almost all of them survive. The transformation of the larva into an adult fly takes place in a month. This means that one insect in just 3 months can form a millionth population.
Step 5
Fly larvae are laid in lard, cheese, ham, salted fish. In the process of consuming these products, the larvae enter the human intestine, where they continue their vital activity, causing various diseases of an infectious nature.
Step 6
Dysentery, which is an infectious disease, is characterized by general intoxication. In addition, there is a lesion of the gastrointestinal tract, in most cases - the colon.
Step 7
Typhoid fever refers to an acute intestinal infection. It is caused by the bacterium Salmonella. It causes intoxication, fever, skin rashes, lesions of the lymphatic system of the small intestine.
Step 8
Cholera, also referred to as an acute intestinal infection, affects the small intestine. As a result, there are signs of watery diarrhea, vomiting, and rapid fluid loss. Severe dehydration can be fatal.
Step 9
Anthrax, which is a dangerous infectious disease, develops extremely quickly. It is characterized by serous-hemorrhagic inflammation of internal organs, lymph nodes and skin.
Step 10
With diphtheria, there is a general intoxication of the body, damage to the cardiovascular, nervous and excretory systems. Tuberculosis, caused by various types of microbacteria, affects the lung tissue, while affecting other systems and organs. Poliomyelitis, affecting the spinal cord, leads to a pathology of the nervous system.
Step 11
The housefly can become the source of these diseases. However, there are blood-sucking flies that can attack humans and animals. These insects are carriers of anthrax, brucellosis, trachoma, tularemia.
Step 12
The gadfly fly is capable of depositing larvae under the human skin. Upon entering the body, the larva penetrates the middle of the tissues, affecting the bones and causing tissue inflammation and bleeding.
Step 13
The tsetse fly can cause sleeping sickness. As a result, a person's lymph nodes in the neck swell, fever, drowsiness, and swelling of the limbs appear.
Step 14
To protect your home from flies, window and door openings should be protected with fine nets. In addition, it is important to keep the kitchen clean at all times, not to leave food available to insects. To avoid attracting the attention of flies, you need to close the trash can. Sticky tapes also contribute to their destruction.
