You might be wondering why flies eat poop. There are many reasons for this, including the fact that flies are attracted to the smell and nutrients of partially digested matter. Flies prefer food that is moist and organic, and poop provides both of these factors. In addition, flies need to deposit their eggs somewhere safe, so poop is a great place to do so.
Flies feed on organic matter and are known to spread bacteria and viruses. They do this by secreting digestive juices onto the food, a substance called fly vomit. They then use their proboscis to suck food, making feces a popular place to find flies. While flies are helpful pollinators, they can be gross. They have been shown to spread E. coli and salmonella and are known to get animal poop on their food.
In addition to being an excellent source of nutrients for flies, feces from human feces are a convenient source of food for other insects. Their food source contains bacteria, protein, and fats, as well as trace amounts of minerals and trace elements. The food is also nutrient dense, which makes it a popular choice among other insects.
While houseflies cannot chew solid food, they have taste receptors on their feet and lower legs. After landing on a tasty food, house flies begin to sample the flavor. They may defecate in a variety of locations, including in a hamburger bun or pile of dog poop.
