Before you buy anything
A few things worth knowing first
Take a class before you buy anything. Most local beekeeping associations run beginner courses in late winter for $50–100. You'll learn more in a single hands-on inspection session than in a week of YouTube, and you'll meet experienced beekeepers who can mentor you through your first year. Find your local association through the American Beekeeping Federation.
Call your municipality first. Many cities allow backyard hives; some don't. Some HOAs ban them outright. The fine for a surprise hive removal is considerably more than a class.
Start with two hives if you can swing it. It sounds like more work, but two hives let you compare colonies — if one goes queenless, you can take a frame of eggs from the other to rescue it. Solo hive beekeepers have no backup. Two hives means you'll actually learn instead of just worrying.
Buy your bees locally if at all possible. A nucleus colony (nuc) from a local beekeeper means bees already adapted to your climate and a laying queen you can verify before you bring them home. Package bees shipped from out-of-state are the budget option, but local nucs survive their first winter at much higher rates.
