Fruit flies are tiny insects that are attracted to ripe or
rotting fruits and vegetables. The flies not only eat the fruit,
they also lay their eggs there. A single fruit fly can lay up to
500 eggs on the surface of a piece of fruit. Within eight days,
the fruit flies that hatch from these eggs are full adults that can
then lay their own eggs. As you can see, what might start out
as a small fruit fly problem can become very large very quickly
