@Kris5902 I think I'm reaching the limits of my English which does not include technical bee terminology

but I'll try to answer. I hope google translate allows us both to understand each other !
First I will say that my partner is the bee keeper and the knowledgeable one of us, I only assist him. If it can help convince your aunt, I have strong reactions to bee stings : we kept that under control for years with an antibiotic onguent ( for which I need a prescription) and antihistamine medication. We always have an adrenaline shot available just in case. But a few years ago we learned that high heat applied for 10 minutes just after a sting does miracle ( blow-dryer or cigarette) and this has been a life changer for me.
Now to your questions. What happened with this particular hive we were told by a professional bee keeper is supposedly not possible, so my story should be taken with caution. We had a first swarm leave the hive at the beginning of may which we caught. Then maybe ten days later I found a second swarm from that hive and we caught it again. We thought it was a secondary swarm except that a few days later my partner opened the initial hive and it was empty. What we thought was the secondary swarm, was actually the whole hive gone. It had left behind frames full of brood and some honey and yes there were queen cups.
So we didn't leave the empty hive there because it would have been plundered very fast by other hives. We took both swarms at a friend's place where we also keep bees, 20 km away.
We torch them because of wax moth ? Or honeycomb moth, not sure what the term is ! We have varroa but I don't think torching makes any difference as it lives on the bees.
For the frames what we like to do is keep frames that have been already built by bees before, either in colonies we have lost, or in upper chambers (? Not sure google translate is correct there). We will put three of those and the rest will be empty frames. We don't like artificial starters made from wax that we don't know the ingredients of.
My partner has been keeping bees for 8 years now and has been making a lot of mistakes, we still make some regularly. It's not easy keeping bees where we live, old people who have done it for years say it was a lot easier before.
Apologies for any strange terms and for having being so long
