Hello everyone im new here and im facing big problems with my beehives... today i got information that is not only me having this problem but is happening all over my country (Macedonia) and other country's from Balkan region. At the start of the winter i had about 60 healthy hives. Now im just left with 10 and they also don't seem to do good. I don't know if its a disease or something like that. We have beehives 3 generations not even my father or grandfather experienced this... So this is the situation. i go to check on my hives on 2 weeks. The hives have honey in them also have the winter food i put as extra. Also they have been treated against ticks/beetles. I do this method same every year and had no problems. Now all food is in the hives and the bees just have disappeared. Anyone experienced something like this so can share experience and tips how to save the remaining ones.
