  1. One of the biggest reasons they're so difficult to swat dead is that all those hairs and bristles you see are extremely sensitive to moving air. When you move to swat the fly its hairs move in response to the air your hand (or fly swatter) is displacing as the hand approaches, so the fly "knows" about your hand before it reaches the fly, and it moves away before your hand gets there.
