Flies lay eggs on decaying organic matter, such as food waste and carrion. These eggs are tiny and white, and they hatch in about eight to twenty hours. Flies also lay eggs in dead animals and manure. Eggs of these insects can be eaten to learn more about how they live and reproduce.
A female fly can lay hundreds of eggs, and each egg will grow into a fly within a few days. If there is food, this can lead to millions of flies appearing in a short time. Adult flies live for about 2 weeks, and some can even lay live maggots. In fact, eating a fly egg is not harmful for humans.
Houseflies are one of the most common types of flies in the world. They have a life span of about twenty-five days, but some species live up to two months. They also live longer in cooler temperatures. Before copulation, female flies need food. This is because maggots can survive without food for two to three days. However, they will eventually die before they reach pupation. Fortunately, if you catch a female fly during this time, you can treat the infestation with highly effective insecticides.
Flies lay eggs on a wide range of materials, including food. Food left out for long periods of time, including spoiled food and leftovers, can be a breeding ground for these insects. Besides food, flies can also lay eggs on trash, feces, and decaying corpses.
