While checking hives a couple weeks back i found 2 double deep hives completely empty. No honey, no pollen, no brood, no dead bees, just 20 empty drawn frames per hive. My guess is the bees absconded and judging by the detritus on the bottom board coupled with the ragged cells were then robbed out. Ive heard of this happening but this is my first experiance with it. Should i be concerned about re-using the frames? Thanks, ted
