Apologies if I am posting this query in the wrong section, I am confused by all the helpful but contradictory advice I am getting from local beekeepers. I. posted before about the fact that a swarm turned up in my brand new hive last June before I had begun any beekeeping. courses so I have had to learn quickly and have been reading and watching videos and asking advice everywhere. My bees seem to have survived the winter and are flying on warm days, but I still haven't opened it up as it is still cold here. Local experts range from saying Leave them alone and do nothing for now (they have fondant still), open up the hive now and treat for varroa with oxalic acid (which I have ready to use, in liquid form), check the bottom board for signs of mites (I have done this and can't see any at all), or one beekeeper who has kept bees for 40 years says she has never ever treated for varroa. Bees seem to be taking pollen into the hive, I just have a brood box, I took no honey last year, just keen to do the right thing but all the incredibly welcome advice means I can't make up my mind as to what, if anything, I should do next. Anyone got any advice for me please?
