I have searched through the old posts and cannot find an answer. How long will it take for the bees to get used to the robber screen? I have been out there two nights to let the cluster on the outside of the screen back in. I had an entrance reducer on to start with but the fighting and dead bees were observed so I think I need to go with the screen (I had this same problem last year, there must be an aggressive feral hive nearby).
Should I just leave the bees out there over night? Will I loose them if I don't remove the screen at night? Other than that my package is doing fine, week number 1. I had the same problem last year and I was slow to react. Trying to be a bit more pro active this year.
