I would guess 3-5 years, although I have seen data from Australia that suggests a much longer natural lifespan (12 years). Untreated colonies are expected to live 3 years, or so. That's been my experience.
A neighbour had one that went approx 20 years. Very occasionaly I took
off a super of honey for him. But a sample of one proves very little.
My educated guess is that a hive will last until it swarms, and then
does not get the virgin away. Going on mating figures from queen
breeding operations this would on average be 4-6 years?!?!
