Flies are less likely to annoy a person who is asleep because they are generally attracted to movement, heat, and carbon dioxide, which are more prominent in awake individuals. When someone is asleep, their body is still, and they emit less heat and carbon dioxide. Additionally, a sleeping person is not swatting or reacting, making them less of a target for flies. Thus, the combination of reduced activity and sensory input makes them less appealing to these insects.
