Cockroaches are transmitters of various diseases, since, when they come into contact with food and the water we consume, they deposit a large number of microorganisms, which cause various diseases in humans.
The cockroach carries pathogens that can remain on your body and in your digestive tract for several days or weeks.
The transmission of bacteria in food can occur by:
Deposit of excrement
Contact of your extremities
It has been shown that these bacteria present in the digestive tract or on the outside of the cockroach such as; Balantidium coli, Entamoeba histolytica, Giardia intestinalis, Toxoplasma gondii are the cause of several dysentery, gastroenteritis, diarrhea. They can also transmit the causative agents of typhoid fever, plague, gangrene, leprosy, cholera meningococcal meningitis, tetanus and tuberculosis in man, they are also intermediate hosts of parasites and can spread many substances that cause allergies, they are also intermediate hosts of protozoa, helminths , viruses and fungi.
To live the cockroaches look for cracks, crevices that provide them with humidity and adequate environmental temperature. During the day it is common to find them in groups or in places of rest or hiding place. During the night they eat in groups. Cockroaches can be divided into 2 large groups, depending on the habitat. Those that prefer very humid places (P. americana and P. asutralasiae) and those that live in drier places (B. germanica and S. longipalpa).
The cockroaches have a gradual development consisting of three stages: egg, nymph and adult. In nymph, the individual is in his youthful state producing various changes until reaching an adult stage according to the species.
The female performs egg laying externally in an oblong ootheca, which are cases where the eggs are at the end of the abdomen. The ootheca of some cockroaches can contain between 30-40 eggs. The female can produce up to eight ootecas throughout her reproductive cycle; under favorable conditions, it can produce between 300 and 400 descendants. Cockroaches can live for one year.
They are omnivorous and in the domestic sphere they feed on anything that is organic (pinches of food, grease, garbage, woolen fabrics, cotton and cardboard). They can also eat many other materials. Once the food passes through your mouth, it runs through the digestive system carrying out digestion and absorption of nutrients, the waste is excreted in the form of faeces through the anus.
