His scientific work resulted in a number of significant milestones: he showed that flies breed and lay eggs and do not, as was popularly believed, spontaneously generate; his microscopic examination of parasites marked the founding of modern parasitology; and in studying chemical treatments to kill parasites, he devised and performed the first controlled experiments in scientific history.

Spontaneous generation, a theory that maggots, fleas, worms and other living organisms developed from inorganic or dead organic matter, was the prevalent viewpoint of scientists for around 2,000 years, since Aristotle first posited a description of the phenomenon. The experiments with maggots and flies were important not only because they refuted spontaneous generation, but also because they used control groups, applying the scientific method to test a hypothesis. The spontaneous generation theory, which claims living things can form from non-living objects, had been put forward by Aristotle and had been widely accepted for centuries.
