After about mid July here in eastern MA, staggering the extracted supers
outside seems to work like a charm. It may have something to do with the
light entering, but I suspect it has more to do with the abundance of yellow
jackets (especially Vespula germanica). They seem strongly attracted to the
wet combs and will be seen entering and exiting the stacks of supers in
increasingly large numbers until frost, and even beyond. Wax moth larvae
probably don't have much of a chance with so many wasps around.
