I’m new to beekeeping and started this summer roundabout six weeks ago with one flow hive and package bees. I just try to get them fit for the winter that they have a good start next year.
One week ago I put the bottom board card in the upper position to learn about my bees and look for varroa. Ants are blocked out with sticky " socks" round the stands of the hive ( works very well). The card looks like in the photo attached.
I have now three questions:
how many bees will be in the hive round about? I started with a package with 1500 bees and a young queen from this year (buckfast F1). Seems they are living now on four to five frames. Breeding is obvious.
these little black double strings on the second photo I can’t identify. Don’t find them in my books. Does anyone know what it is?
I found four death adult varroa mites on the board (within one week), no young ones. Any reason to worry or treat?
Thanks a lot for your help!
