Ok, Yesterday was good weather. The Bees were sure confused about the new traps. Obviously they found the way out, and were all over them. I went back out to them as the temp cooled, and sun was going down. They were all back in. I removed the trays and got a little more than 4 oz clean pollen. I thought that was pretty good for time of year and temps, and really only 1 day worth? There was only a couple dead behind each door, and no bee parts in the pollen. So far I will say they are working pretty good.
