                                                          Cockroaches live in dark, damp or dirty niches inside the house. I suggest you spray insecticide on the surfaces frequented by these pests. Use an aerosol spray with a long nozzle to get at holes or cracks. Regularly do this for about a month. If this problem still persists then it is time call an exterminator.
