My experience with packages is they are "lazy" - slow start; probably because there's no nectar available here when packages from the south are available. But, your late-May or June swarms should arrive right on time!
Want to buy 2-6 swarms. Hopefully for less than $100 (incl. freight to Alaska) each.
Natural or artificial, so long as formed by a natural impulse. Yes! This means last year's queen is okay! Please cage her, though, for shipping - don't need them building a hive out of the shipping container.
No frames. Alaska outright bans import of "used" hive equipment.
