The German cockroach, Blatella germanicai, is an urban pest that has been broadly distributed. They are commonly found in apartments and restaurants. They are 0.5 to 0.625 inches long. These cockroaches don’t fly though they have wings. They like dwelling in a moist and warm environment. Majorly, these species are scavengers and feed on different kinds of foodstuffs such as meat products, starch and sweets; most of the times they get their food from the garbage. German cockroaches are generally active during the night as they scavenge for food and their mates. As for the day, they bury themselves in cracks and dark places with a humid and warm atmosphere. In and out the cracks, they can move with ease due to their wide and flat bodies. If spotted during the day, it’s either there is inadequate food or their residents have been sprayed with pesticides.
American cockroaches, periplaneta Americana is common in Pennsylvania and is so far, the largest species. They can be found in city dumps; precisely in tunnels and basements of bakeries and stores. Adult American cockroaches range from 1 to 1.5 inches and are red-brown in complexion. They have wings, fully developed though rarely fly in the northern regions. Indoors, they do hide in the warm, moist and dark places like floor drains, sewers and in bathtubs.
Brown-banded Cockroaches, supella longipalpa have dark brown bodies and the adult ones are 0.5 inches long. They have brown bands across their bodies near the abdomen. Dry and warm places are their hideouts; these may be inside closets, cabinets and other furniture. They prefer places close to the ceiling rather than the floor.
Oriental cockroaches, blatta orientalis are named water bugs since they prefer dumpy, cool and dark areas. They’ll be found beneath sinks, drainages and wet basements. They also survive on plants and can be spotted under leaves, flowers and shrubs. Oriental cockroaches are known for their sluggish movements. The adult ones are close to 1 inch long. In complexion, they are dark brown and have a greasy sheen on their bodies.
Diseases spread by cockroaches
Cockroaches move about from gardens, buildings to filthy places like the drainage, latrines, and sewages; feeding on substances on these areas. They are therefore carriers of germs and spread diseases. Those that feed on faeces such as the German spread bacteria that cause poisoning of foodstuffs. Cockroaches are vectors for Shigella and Salmonella bacteria which are responsible for diarrhoea. Moreover, they are carriers of organisms that cause cholera, dysentery, typhoid and viral diseases like poliomyelitis.
Other harmful effects caused by cockroaches are food contamination and secretion of an awful odor. Some people have developed allergies and sneeze due to cockroaches’ contact or smell. Cockroaches may also invade human body parts such as the nose and ear and these may lead to visiting a clinic for removal.
Management of cockroaches
When insecticides are combined with proper sanitation, they reduce the reinvading ability of a cockroach. However, chemical control ought to be applied with caution. Baiting technology has been effectual in the control of cockroaches and other insects. The technology does not pose dangers to human beings and it eliminates cockroaches effectively. The gel bait involves usage of a small dose and the liquid pesticide supplements it. The baits are kept on the insect’s hiding places. Baits have proved to work better than sprays.
The IPM approach is an effective measure used to eliminate the presence of cockroaches since they can be detrimental to our health. The approach can be summarized as reducing sources of food and water, eliminating their hideouts, the use of baits and traps to check on their population. Sprays should be avoided since they do not offer long-term control; besides that, they may disperse the insects to other regions. Dusts also provide long-term controls though they are slow in acting.
