Flies are an almost unavoidable nuisance in most homes, especially during the warmer parts of the year. They are one of the most common insects on the planet. They breed and feed in filth, including garbage, faeces, and rotting or spoiled food.


House flies about 4 to 7.5 mm long, usually gray coloured with four black stripes on the thorax. House flies are covered with small hairs that serve as taste organs. Their compound eyes are extremely complex: thousands of individual lenses allow them a wide field of vision.

House fly nuisance

Since they live in such close proximity to people, house flies are generally unwelcome. While usually just a nuisance, these pests can carry a variety of diseases harmful to both humans and pets. House flies pick up bacteria, fungi, and viruses and then spread these pathogens by contaminating food and water. They are known to transfer over 100 pathogens resulting in ailments, including typhoid, tuberculosis, cholera and dysentery.

Signs of a House Fly Infestation

The adult flies are the most common sign of activity. They prefer corners and edges or thin objects to rest on. Indoors, they rest on floors, walls and ceilings during the day. Outdoors, they are found on plants, the ground, fence wires, garbage cans, etc. Waste products around the home increase the chance of a house fly infestation.

House fly control

House flies can be a real nuisance when they are flying around. But they can also transmit diseases, so it is important to get rid of them. House fly control is not always as easy as it sounds. There is often more involved than a fly swatter. House fly control involves several steps.

1) Cleaning breeding site and sanitisation around house

  • The first step is identification. It is easy to confuse house flies with several other fly species, including cluster flies. The different types of flies may look similar, but they require different control methods.
  • It is also very important to identify the places where the flies have been depositing their eggs. It may be something simple like an uncovered trash can or a bowl of pet food on the patio. However, the house fly breeding site could be something that is not obvious.
  • The breeding site must be cleaned up or removed. If the breeding site is not removed, the flies will continue to be a problem.
  • Keep the rubbish or trash bins tightly closed so that the flies can’t access them for breeding or feed.
  • If you have dogs at home keep them, they can be a source of fly attraction to your house. Dogs near the front door attract flies so keep them away.

2) Elimination of adult flies

The next step is to eliminate the adult flies. Depending on the situation, it can be done by

  • Fly bait
  • Or a chemical spray around as well as inside the house with house fly problem
