Do Flies Pee?

House flies do not have a bladder or any other organ to store urine. They, therefore, excrete both urine and feces at the same time. This process is known as “micturition.”

Interestingly enough, flies used to be a common way to diagnose diabetes. Before modern medicine, doctors would leave out a person’s urine and see if flies were attracted to it.

If the flies came and made a meal out of the pee, that meant there was sugar in the urine- a telltale sign of diabetes.

Interestingly, flies might fart when they defecate or when their digestive gasses are reabsorbed and released through holes in their exoskeleton. The gas accumulates in the abdomen and is expelled through the anus or the genitalia.

It’s not just the fact that flies fart, but they also produce some pretty vile droppings. In one research, researchers collected fly poop from a variety of surfaces and analyzed it.

They found that the house fly produces about 1,000 times more bacteria than any other type of common fly. So next time you see a fly, remember that it’s not just farting–it’s also leaving behind a trail of bacteria!
