These are particularly dangerous insects as they carry bacteria and other harmful micro-organisms from the most filthy places onto our food. Flies are responsible for causing cholera, dysentery, typhoid and other food-borne diseases. Flies have the filthy habit of regurgitating food from their gut as they feed, and excreting faecal pellets on the food. They are attracted by the odour of decaying organic matter where they breed and feed.
Flies are not only a nuisance pest but of greater concern is their potential as a carrier of disease organisms, having been found to harbour over 100 different pathogenic organisms. House flies are general feeders, being attracted to a wide variety of substances from excrement to human foods. Because of their sponging mouthparts, they can feed only on liquids. However, through regurgitation they are able to liquefy many desirable solid foods. Also, a house fly excretes and regurgitates whenever it comes to rest. This habit coupled with its many body hairs and bristles and the sticky pads at the base of the claws on each leg make house flies well adapted for transporting disease organisms.
House flies have been shown to harbour over 100 different kinds of disease, many of which are associated with filth. Such pathogens include those causing
They have been shown to be disease pathogen transmitters via their vomit, faeces, and contaminated external body parts
Larger than the housefly, these are shiny, metallic blue or green in colour. They’re also known as the “Blue-bottle” fly. They frequent garbage dumps, dead animals, excrement and food. They are recognised by the loud buzzing sound they make when flying
These are very small and yellow-brown in colour. They fly around decayed fruit, vegetables or rubbish. Fruit flies tend to be more active around dawn and dusk.
Flies are best controlled through proper sanitation.
