New swarm moved in

[Monkey]

I had an empty hive, lost to a swarm last year, with drawn brood box and a half full super, that I'd been meaning to tidy away for ages now.

Luckily, or perhaps not, a new swarm has moved in and made themselves at home.

I'm guessing that there is no risk of them swarming away, so I plan to just leave them to it for now. Is this the right thing to do, or should I be thinking about treating them, or whatever?

I would check them in a week and vape them.
