They do not have a set of wings and so can only move on floors, walls and even the ceiling of the place. Their body develops to their adult phase in around four weeks and once fully grown, they lay eggs three or four times a year. So it’s not long that three or four bugs can turn to more than twenty within a few weeks and so. If untreated, this number dangerously rises. These bugs transmit no disease to humans or animals.
