Darks/lights

A considerable amount of noise is generated when taking longer exposures over several subs I assume that you also need to take darks and lights of the same exposure time etc to remove the bad from the good pixels.

Is there a ratio of the number of dark/lights to subs required to reduce noise or is it a case of more the merrier.
