The past two weeks when I have been near the hives to feed sugar syrup, I have noticed a unique smell. It's not a dead/rotting smell but a semi sweet but sickening smell? There is never any sugar syrup left when I check, minimal dead bees in feeder (top feeder). However it has been 10 days since I have been able to check my hives due to work. Could this be a smell of disease? Or I saw where its possible it is the goldenrod smell capped honey? I have treated all four hives with Apivar per my bee mentor and they are due to be removed tomorrow (after 56 days is this correct?) Should I also be treating the hives for anything else before winter?
Appreciate any and all feedback. First time bee keeper since May, 4 hives and need to get as much information about fall management to keep my hives successful for overwintering. Thank you.
