You likely have a couple of weeks to do this. A very quick look after a week can check for any brood. If none, just wait for open brood - without pulling the whole hive apart. Once there is open brood they are unlikely to abscond. If there is a small area of capped brood, there is nothing stopping you removing that capped brood?
If you have a little capped brood, just think when you will need to vape again - it would not be needed after 5 days unless the mite load was considerable, so only two doses required to reduce the mites quite considerably. Certainly sufficient until the autumn mite clear-out before the winter bees are raised.
