Hello
Does anyone out there have any experience with a robber screen? I have a weak hive with a fairly new queen that I am trying to feed with a top feeder. I have tried by reducing the entrance to a one bee width,and by placing twigs to reduce the size, and by placing obstacles to the entrance to no avail. I am now trying a robber screen plan that I found on the internet. It keeps the robbers out but it also seems to keep the natives from returning home. Do you know of any robber screen plans on the internet or do you feel this is futile since they will not build up a population and stores large enough to overwinter even though I am willing to feed? This is New England
Thanks
