Fact: Fly digestion cannot happen until food is sucked up and mixed with stomach enzymes. It is then regurgitated and feasted upon causing fly spots around your home. 

Fact: In terms of food preferences, houseflies show no favourite preference between animal excrement and any human food source. 

Fact: Flies are a particularly undesirable pest to have in your home or business. Apart from being a real nuisance they are also a carrier of many disease-causing organisms.

Lesser house fly (Fannia canicularis)

There exists a range of different fly species in the home – but those most likely to be seen in this region include the common housefly and the lesser housefly. Other species you may see include a range of blowflies, crane flies, fruit flies, lake flies, moth flies and cluster flies. Identification of any fly species is critical, as control methods have to be tailored to their various behavioural patterns. Common houseflies, for instance, tend to avoid light-coloured smooth surfaces, instead preferring to rest in darker areas. However when disturbed they will fly towards light. The ‘Lesser housefly’ flies around in the middle of the room performing aerial acrobatics like a fighter plane, circling each other and making quick darting movements. These acrobatics represent a form of display and courting behaviour. 

Some flies are not even bad and are biological controls for other insects such as robber flies.
