Flies have a metallic green, blue or yellow brown body. There are more than 16,000 species of flies in Australia, and they can carry more than 100 pathogens. An example is the house fly, which can carry Salmonella, Staphylococcus, E. coli and Shigella. These pathogens can deliver disease to humans and animals which include cholera, typhoid fever and hepatitis. These flies range in size from 7 – 13 mm in length.
Flies can move quickly from rotting, disease-laden garbage to exposed human foods and utensils, so it is easy for them to spread diseases readily. These common household pests should not be underestimated.
Normally, the life expectancy of a fly is 8 days to 2 months or, however some species have longer life expectancy up to a year. The fact is that one pair of flies can produce more than 1 million offspring through their offspring’s offspring in few weeks means that this pest can grow in population exponentially.
