It develops in decaying animal and vegetable material including dung. Drains that need to be cleaned cause most household sewer fly problems. Scrubbing drains with a stiff brush often removes the scum lining. Garborators sometimes get a buildup of waste that can cause a problem. Take kitchen garbage out regularly to reduce the chance of sewer flies breeding in the garbage.
Fruit flies are light brownish yellow in colour with bands across the abdomen.
They have red eyes. Females lay up to 200 eggs in moist food especially fruit. Rotting fruit odours attract fruit flies. It takes about a week for the adult to develop. An adult lives two weeks.
