The ootheca can either remain attached to the cockroach until

                  the eggs are ready to hatch or deposited in a hidden place where the eggs
                  will hatch. Other roaches grow their young in an ootheca inside the mother’s

                  body.



                                     After 6-8 weeks, immature cockroaches known as nymphs
                  emerge from the case. Young cockroaches are mostly white and will gain

                  their brown color as they age. These nymphs will feed and go through a

                  series of moltings throughout a year as they develop into adults. Food in the
                  home and even pet food can sustain a cockroach. The adult cockroach can

                  live 1-2 years.

                                     At home, cockroaches feed on leftover foods and scrapes made

                  by humans. They also feed on dogs and cats’ foods, old woods, and garbage.

                  When your kitchen is untidy more cockroaches will be attracted. Some
                  cockroaches bite humans and cause infection and allergy. Cockroaches can

                  sometimes play a role as carriers of intestinal diseases, such as diarrhea,
                  dysentery, typhoid fever, and cholera.



                                          Cockroaches stay in dark places. They don’t like lights. They

                  infest the kitchen during the night time or when your kitchen is dark.
                  Cockroach breed and stay under your sink, in the drainage of your house,

                  behind the refrigerator, inside dark cabinets or drawers and moist and warm
