Cockroaches are nocturnal insects which remain hidden throughout the daytime in cracks, holes or crevices of kitchens, godowns, hotels, public toilets, neglected bags, boxes and also other articles but turn out at nighttime as a way to obtain their nutrition. They are fast runners and run quickly on being disturbed. Cockroaches also have their wings to fly as a way to avoid their predators. Body colour ranges from brown to brownish black.

The breeding season for cockroaches is from March-September through which they remain very active. Copulation is as well as egg laying. Eggs are laid in bag like structures known as ootheca that are deep brown in colour. Oothecae are marked by sculptured patterns where you can definite shape that's characteristic of a species. The number of eggs within an ootheca is different from 15-40 arranged in double rows. Formation of ootheca takes a few days and quite often could be found connected to the substratum. Female lays around 100 oothecae in their own overall life time each containing 16 eggs. The hatching of eggs depends upon the humidity and temperature in the environment. They hatch after 35 days in summers but take 100 days in the winter months. The larval development can be dependent upon the climatic conditions. Nymphs or even the larvae come to be adults in A few months in summers but might take A couple of years for being adults in winters. The roll-out of nymphs into adults is of hemimetabolous type and they shed their cuticle during moulting. 10-13 moults have already been notice in the life history of cockroaches. Under favourable conditions 2-3 generations exist in 12 months otherwise simply a single generation is located.

Cockroaches are omnivorous and go after a number of food materials. They're dirty, distasteful and odoriferous creatures and are attracted towards garbage, food stuffs consumed by humans. They enter any food material consume it, discolour and spot it with faecal material by leaving behind a foul smell.

Infestion of cockroaches in homes may be prevented keeping all of the pipelines, safety tanks, tightly sealed. Food stuffs needs to be completely covered.
