I'm seriously considering taking up beekeeping as a hobby, so I can have honey and wax for various uses. There is a nearby community garden where bees have been kept before, and an unused box beehive (with supers, I think) that is available. What I'd like to know is if there are any special steps that need to be taken with a previously used hive before new bees are introduced. Do I need to worry about mites already being there, for example, and how to I treat the hive? I'd appreciate any insights.
