Before you install another package search for info on this website about combatting SHB. In the Deep Southeast if you don't actively control beetles you will lose your hives. SHB don't have to come with the packages, they are present everywhere in the SE. They fly in and make themselves at home. Many on this forum will tell you that a strong hive will keep them down. I've not found this to be the case. They'll infest the strongest hive you own and in a couple weeks that hive will abscond and the SHB larva will finish off the combs. Down here in East Central FL we say that we have 2 types of beetles: 2 day beetles and 3 day beetles; that's how long it takes to have adult beetles in a new hive. With no controls, we can have 100's of them in a weeks time.
