Getting Rid of Flies | Infestation of Flies

There are many different types of flies but the most common we deal with are house flies, fruit flies, filter, sewage and drain flies and blowflies, bluebottles and greenbottles.

House flies

House flies are one of the most common insects on the planet. They breed and feed in rotting organic matter in waste bins and garden compost, feces and rotting or spoiled food. They lay their eggs in clusters which hatch quickly. House flies spread bacteria and disease from things they have touched before when they land on human food.

Poor sanitation and bins only being emptied every two weeks as well as windows and doors being left open can lead to house fly infestations.

Treatment

  • In domestic situations we usually apply a residual insecticide to the interior walls and ceilings which kills flies as they land on the treated surfaces – this lasts 1 to 3 months. The surfaces to be treated must be clean and dust-free. Cutlery, food, clothes, towels, toothbrushes, etc must be covered prior to the insecticide.
  • For commercial situations the most effective method is a combination approach that may include the application of a residual insecticide, the installation of electronic fly killers and flyscreens.

Fruit Flies

Fruit flies are common outdoors but often come inside to breed. They breed and feed on ripe, rotting and decayed fruit and fermented drinks such as beer and wine. They also may breed in drains, waste disposals and bins. They have the potential to transmit disease from things they have touched before when they land on food.

Treatment

In domestic situations we usually apply a residual insecticide to the interior walls and ceilings which kills flies as they land on the treated surfaces – this lasts 1 to 3 months. The surfaces to be treated must be clean and dust-free. Cutlery, food, clothes, towels, toothbrushes, etc must be covered prior to the insecticide.

Filter, Sewage and Drain Flies

Filter, Sewage and Drain Flies gather, mate and lay eggs in moisture or standing water. The slimy film and sludge that forms in sewers and drains is a favorite breeding spot. If these flies are present in a house there is likely a slow or clogged drain. These flies are found at or near sewage works or sites with damp organic sludge. Surrounding houses may be affected.

These flies are a nuisance because they infest in large numbers. They may plug pipes and spread bacteria from the filth they live in, possibly contaminating food in the process. However, they are not known to spread any disease to humans.

Treatment

  • In domestic situations we apply a specialised insecticide to the breeding site which is usually a drain. Inside the property we usually apply a residual insecticide to the interior walls and ceilings which kills flies as they land on the treated surfaces – this lasts 1 to 3 months. The surfaces to be treated must be clean and dust-free. Cutlery, food, clothes, towels, toothbrushes, etc must be covered prior to the insecticide.
  • In commercial situations we apply a specialised insecticide in sewers, drains and on filter beds in sewage works.

Blowflies, Bluebottles and Greenbottles

Blowflies, bluebottles and greenbottles breed and feed off rotting meat, dead animals and birds, rotting organic matter in waste bins and garden compost. They spread bacteria and disease from things they have touched before when they land on human food. If the flies lay eggs in food which is then swallowed by a human they may contract myiasis, an infestation of fly larvae which feeds off human tissue.

Blowflies, bluebottles and greenbottles often appear in large numbers as they have just emerged or the adult flies have infested rotting organic matter or a dead animal. Maggots and flies become a problem in domestic situations when bins are only emptied every two weeks. They are also a problem in slaughterhouses and related industries.

Treatment

Blowflies, bluebottles and greenbottles are difficult to get rid of as they are bigger and stronger than other flies.

  • In domestic situations the food source for the maggots may have already been removed by the time the adult flies and/or maggots are noticed. We usually apply a residual insecticide to the interior walls and ceilings which kills flies as they land on the treated surfaces – this lasts 1 to 3 months. The surfaces to be treated must be clean and dust-free. Cutlery, food, clothes, towels, toothbrushes, etc must be covered prior to the insecticide.
  • For commercial situations the most effective method is a combination approach that may include the application of a residual insecticide, the installation of electronic fly killers and flyscreens and treating the breeding site.
