You step outside to take out the trash and notice something strange: hundreds of tiny white specks covering the lid of your garbage can. At first, they look like scattered grains of rice. Then you lean closer—and realize they are moving.
It is an unpleasant surprise, but there is a surprisingly simple explanation.
Those tiny moving specks could be maggots, the larval stage of flies. Although the sight can be unsettling, these larvae commonly appear around household garbage when flies find a suitable place to lay their eggs.
