Cockroaches
Cockroaches, which hide in small cracks or crevices during the daytime, can reach lengths of 18 to 60 mm depending on species. They feed omnivorously on various organic substances, including tissue, leather and paper.
The German cockroach (Blatellagermanica) is very common, and usually encountered in houses. It is relatively small and has a short life cycle of 3 to 8 months, depending on temperature. The German cockroach females carry their packages of 20 to 40 eggs with them for about 4 to 5 weeks, and then lay the eggs randomly shortly before hatching. The larvae shed their skins several times, and gradually resemble adult cockroaches more and more closely, only they are smaller and have no wings.
Cockroaches can be carriers of a high number of bacterial and viral diseases such as diarrhoea, leprosy, catarrhal colitis, infectious hepatitis, anthrax, salmonellosis, tuberculosis and fungus diseases (aspergillusflarus).
The cockroach's excrement, skin and vomit are responsible for allergies. House dust mites and cockroaches are the commonest cause of insect allergies. In the USA 10 % to 12% of the population reacts allergically to cockroaches.
Cockroaches like e.g. the Oriental Cockroach (Blattaorientalis) and American Cockroach (Periplanetaamericana) occur throughout the world, especially in tropical regions where the environment is humid and warm.
Preventive measures and control
• Avoid accumulating rubbish and rotting substances
• Do not leave food or meals uncovered
• Keep kitchens and cooking untensils clean
• Use insecticides
Name: Cockroaches/Roach
Cockroaches are insects of the order Blattaria. This name is derived from the Latin word blatta. There are about 4,000 Species of cockroach of which the most common on to affect us are the American cockroach- Periplaneta Americana, Which is about 30 millimeter (1.2 in) long, the German cockroach-Blattela Germanic, about 15 millimeter (1/2 in) long, and the Oriental cockroach-Blatta orientalis, about 25millimeteres (1in).
Disease: Cockroaches are know to transmit bacteria that cause food poisoning (Salmonella spp. And Shigella spp.) Other disease-causing organisms such as Staphylococcus spp., Streptococcus spp., hepatitis virus, and coli form bacteria, typhoid and dysentery Indoor infestations of cockroaches are an important source of allergens and risk for asthma among some populations.
Spread:Cockroaches as pests are found in Homes, Schools, Restaurants, Hotels, Hospitals, Shops, Warehouses, Offices and virtually in any structure that has any food preparation or any storage areas. They contaminate food and eating utensils, destroy fabric and paper products and impart stains and unpleasant odors to surfaces they contact.
