OK well since you've requeened with supposedly varroa resistant bees, you might be able to keep them without treating. However a hive with NO mites is a rare thing, if it even exists.
In your previous post, you said "Just because you are a human, I am not going to assume that you have pin worms, hook worms, or shistosomes". Couple of things. If you were somewhere in the third world where people have no medical treatment, you may be better to assume folks could have them. They are rare in the US because they are treated for.
And the other thing people get messed up with is comparing bee / mite relationships, to either people, or other ecosystems. For example a while back I saw mites being compared to a prairie ecosystem and the relationship between prairy dogs, coyotes, etc. It's actually a whole different ball game because a (for example) prairie ecosystem, is something that's been in natural balance for a long time. Varroa is newly introduced to apis melifera and does not have a balance. One day maybe, but not yet.
