It's no problem but most people would not worry about fumigating super frames.
It is the frames which have had brood reared in them which present a much greater disease risk.
I lost a load of super frames to wax moth . Ever since I've fumigated with acetic acid , no problems with residual fumes . Stack the supers after about a couple of weeks , allowing ventilation and all should be ok !
I believed that supers were of no interest to wax moth and thought I was ok, I was indeed for a few years but got caught out , only the once mind :)

I spray mine with stuff called Dipol (?) which a friend supplied as a replacement for Certan ... bacterial spores that, if ingested, kill moth larvae. Presumably Bacillus thuringiensis or similar. I've not had any problems with wax moth since doing this. I do the same with drawn brood and sealed stores.
