The common housefly is likely a familiar sight to most people. It accounts for about 91% of all flies in human habitats and is one of the most widely distributed insects, worldwide. Interestingly, the housefly doesn’t bite living creatures but it can still cause serious diseases. It carries bacteria on its sticky foot pads and its hairy body and passes on those bacteria when it touches everything. Houseflies can carry over 100 pathogens including typhoid, cholera, dystentry, anthrax and parasitic worms. Even though adults only live for up to a month, the females can lay about 500 eggs in that time from about 36 hours after a female fly emerges from its larval pupae.
