Adult house flies grow as large as 8 to 12 mm in length. The flies thorax is grey in colour with four distinguished black lines running down its back and its entire body is covered with what looks like tiny hairs. Males are slightly smaller than females with the females having more space between their brightly coloured red compound eyes. Like other two winged flies that belong to the Diptera family, they have only one pair of actual wings as the hind pair have evolved into small halteres that are used to aid flight stability. Other flies that may be confused with housefly are the lesser housefly and stable fly as they appear very similar.

The housefly is without doubt the most common, domestic flies around. They are the most distributed insect as they can be found world wide. Out of all flies that inhabit human habitats, the housefly makes up 91% of them.
A female fly can lay a batch of between 75 to 151 eggs at any one time, while laying a maximum of around 500 eggs in her lifetime. Fly eggs are a white colour measuring at about 1.2 mm in length. Within a day of the eggs having been laid, the eggs will Hatch into larvae or otherwise known as maggots. The now pale White maggots measure between 3 to 9 mm in length, have no legs and are thinner at the end where the mouth is. The maggots will then thrive and feed on the likes of dead, decaying organic material, garbage and feces. The maggots will grow through three instars' over the period of at least one week. Once they have reached their third instar the maggots will find a dry and cool place to transform into a pupa. As a pupa, they are a reddish or Brown colour measuring around 8 mm in length. Once the pupae have matured, and adult fly will emerge from the pupae. Once the fly has emerged it stops growing and what you may think is a young fly is merely a small fly that did not get lots of nourishment while it was a maggot. As adult flies in the wild they will live between two weeks and month while in captivity such as in a laboratory they can live longer.
A female fly will become receptive to mating in only 36 hours after emerging from its pupa stage. Once a male is found mating occurs with the male mounting her from behind and injecting her with his sperm. Copulation will take very little time, a few seconds to possibly a couple of minutes. The female fly will normally store the sperm and mate only once using the sperm several times for several sets of eggs.
Temperature plays a large factor in the whole process as the warmer the conditions, the faster the development process will be.

Disease transmission.
Houseflies are mechanical transmitters of diseases via its hairs, mouthparts, vomitus and feces. They transmit the likes of parasitic diseases, bacterial diseases and viruses such as:

  • Typhoid.
  • Cholera.
  • Dysentery.
  • Pinworms.
  • Roundworms.
  • Whipworms.
  • Hookworms.
  • Tapeworms.

These are contracted through the flies eating habits as they will visit the likes of sewage, garbage, rotting material including carcasses, excrement, etc. People are at risk with anything that comes into contact with flies and ourselves, especially food.

Pest control.

  • Being clean is the first step in the fight against houseflies. Sanitation and a higher standard of housekeeping are very important to help prevent flies from becoming a problem.
  • Rubbish/garbage should be removed from the home around two times a week, if not more often and shut in tightly closing bins outside. This should be done as flies will find your rubbish/trash a lovely home for their young. The tighter the lid shuts the better as the smell from the rubbish can attract many flies.
  • Periodic cleaning of your rubbish/trash can and kitchen can are a good idea to prevent a build up of rubbish left in the bottom and to remove any smells.
  • Outside trash cans should be kept as far away from doors and windows as possible.
  • Install window and door nets/screens to prevent flies entering your home.
  • If you have pets, make sure that excrement is cleaned up regularly.
  • Dead animals found in and around your property should be removed as soon as discovered.
  • Food that is exposed should be covered up leaving no food uncovered.
  • Hard to reach areas around your home should be kept clean especially floor areas.
  • Blocked or gunged up drains can result in odours attract flies who will then use the gung to breed in. Keep these clean.
  • When in doors use fly traps, sprays and lights to help control flies that do find their way into your home.
