How do flies and other insects walk up walls without falling?

Good question indeed!! Flies and other insects walk up walls without falling because they have microscopic bristles or hairs at the bottom surface of their feet. These bristles have fissures which increase the surface area for cohesion and enables the flies and insects to walk up walls easily without falling.
