I'm not sure where to ask this so I will just explain what happened. I live in Mojave, Ca, the desert. We have a hive and there came a point about a month or so ago that I was worried because the girls were not out and about. My husband said it was probably too cold for them to go out or windy. A couple of days ago I opened the hive and we found that there were a couple of clumps of dead bees stuck to the frame but nothing else. We can't understand if they died and why or just left the colony. Our neighbor behind us has 2 oleander bushes in his back yard and there is one next door, so I was wondering could they have been poisened or what might have happened to them. We harvested the honey from the frames and got quite a bit of honey but the bottom box, the frames were dark brown. In an attempt to save the frames, I started scraping the wax and it was black and very smelly, I'm assuming they were dead baby bees waiting to hatch. Any one have any idea what might have happened to them? Do you think the cold killed them or something else? I'm baffled by this and was hoping someone here could help. We have 2 new sets of bee's coming in April, along with another hive kit, and we've cleaned up all traces of the former hive. But I'm just dumbfounded as to what happened and don't want it to happen again, it's expensive to replace all those bees. Thanks in advance.
