ok, I have written this post twice but getting all password ducks in a row has been tough. So for now, the pics are at The bees absconded before I cut the tree down. No bodies. Would like to use brood comb in swarm traps if it is safe or can be made safe. But this looks ODD. Obviously it's the bee tree comb, not my beloved mazda or pink seed corn. I don't understand what I am seeing. Will try to post specific pics after I get ONE post to actually post. Thank you for your patience.
Looks like a little bit of mold on the old comb. Will work good in a bait hive. Pull out some of the old comb and rubber band it into some old frames. You are really only after the smell anyway.
I have BT. Guess I should get all of the comb out of the trunk and spray it before I move it into my bait hives. Thank you for the reminder
