Best way to store drawn comb without wax moths destroying it — and what to use instead of mothballs?

Fifth year in Małopolskie, and I've just pulled about 25 drawn supers plus a stack of old brood boxes for storage. Last autumn wax moths turned four of my stored brood combs into webbed sludge, so I want to do it properly this time. My uncle (old-school beekeeper) says just toss naphthalene mothballs in the stack like he always did. Something about that smells wrong to me, literally — doesn't that soak into the wax? What's the real playbook? I've read fragments about freezing frames first, Certan/B401 spray, storing with light and airflow instead of sealed dark stacks. Which combination actually works, and do honey supers need the same paranoia as brood comb?
