I was wondering if anyone had used one of the robber cages when working their hives and if it worked very good. We are in a drought and have had mostly temps in upper 90s for several weeks. I am raising my first batch of queeens now and it seems that nearly anything will set off a robbing frenzy. I need to get into hives now to find the old queen and requeen. It seems nearly impossible to have them open long enough to find the old queen. I have seen pictures of the robber cages and wondered if they work. For those hat don't know ,they are screened cages about 3ft wide, 4ft deep and about 6 ft tall without a top and bottom.
