I'm pretty sure the bees were dismantling my wax combs...there were only a handful of yellowjackets and thousands of bees. I had to get them all off the frames this weekend before they took them down to bare plastic foundation :shock: I think putting them on the hives above the inner cover would be better, but when I tried that they seemed intent on expanding onto them and rebuilding, instead of cleaning, so I set them out a little ways from the hives and it was a robbing frenzy for a few days...probably not the best idea, but it worked, and now with the cool weather, everybody has settled down.
BTW - I have found compressed air from a long hose with a spray nozzle to be a lifesaver in clearing frames quickly (a tip that I read on here in a different post) :-D
