We realize that, but we didn't lose the hive because of a disease, they didn't have enough ventilation through a bad winter and got wet. Since we got new bees again they've been doing fine... it's been nearly a year, we have mite traps and don't show any getting stuck to them. So far there hasn't been AFB, or worse, European FB in our area.. thankfully. We wouldn't have started with brood frames we didn't know the history of. If we get a second hive, we'll need more supplies, and we'll either build new supers ourselves or buy new ones. There is a radiation sterilization service available for used equipment as well if you want to go that route.
