I can see a queen cup in the second photo, I wouldn’t be concerned about that one. It wouldn’t warrant me looking inside it. However I’d look inside the two, possibly three queen cups in the 3rd photo because they are made with fresh wax & extended down a bit. They might be fresh queen cups, which bees build all the time, while they have no intention of swarming at that time.
To give a simple answer: if I have any concerns about extended queen cups, I always look in for eggs, larvae or even a wet substance that I think bees place in there to encourage the queen to lay.
I’m going to check them tomorrow to see if there is anything in them. I have been advised to carefully remove them if empty and keep an eye out for further such activity.
There’s not much use tearing those queen cups down. The bees will only build them again.
After nearly 30 years of saying “bees hatch”, I discovered since being on this forum that eggs hatch & bees emerge. I’ve developed the habit of saying “bees, queens & drones emerge”.
