Yes, but then I'm potentially buying new bees every year

. And presumably from different suppliers if I'm buying from someone local.
Don't buy, trap swarms. I've not bought bees in years, and amassed 20 colonies just playing around.
When you buy bees. You are definitely buying bees treated for mites and fed with refined sugar... Hate to say it, but you are getting compromised bees.
I bought two colonies (5) years ago. One died in their second year. They were always weak, and I had no inclination to save them. The other was also very weak, but two years ago they requeened, and have been a very strong and prolific colony since.
As time passes, I have more and more colonies that have proven to be survivors. So, now, I can split those colonies and continue to increase the number of good genetics. Some bee keeps also kill off drones. I swear to God humans are inept. Drones carry good genetics to areas where new queens are mated. I want that to happen, I want my strong colonies to produce enough that queens are being mated with strong genetics, not inferior.
Beekeepers in general I have found to be a selfish bunch. Make the bees do what I want, not what they deem necessary for survival. Squash queen cells, kill drones, take all of their honey and feed them Costco sugar. Treat them because if I don’t, they may die, and that will cost me money. Don’t let them swarm, if they do, they may not requeen, and I may lose them… or at the very least they produce less honey for me.
Each step of the way we compromise them, for ourselves. Beekeepers are a selfish bunch.
