I put a small swarm in an empty, new medium nuc about two weeks ago. On day two they started tumbling out and dying. Two weeks later the hive was pretty much empty with all the dead bees outside. I am going to assume that the bees got into pesticide somewhere.
My concern now is reusing the hive and frames. They did begin drawing comb on the frames before they all died.
I do not want to contaminate the next bees that I put in that hive.
Should I re-use the frames at all? Should I use as is, with the partially drawn comb, or should I scrape them and reuse?
