I've got two hives at a friends house that I haven't checked in a while, today I stopped in to check the hives and one had wax moths. I couldn't find the queen or any evidence of her (no brood or eggs) but there are still a pretty good number of bees in the hive.

There are very little stores in the hive, a small amount in a super and maybe two frames in the brood box. I would like to at least save the bees that are left. What would be the best way to proceed at this point?
