Re: Robbed in January :(
Sounds like you did everything you could. I recently had a robbing of smaller hive and I tried something new. I had a plastic tablecloth backed with a soft felt like material in my shed. I covered the hive after reducing the entrance down to a couple bees with the soft side out and roped it around the hive. It overlapped the entrance, straped about halfway down. This was going on at dusk and I had to go to work so I was trying to do something quickly. Then I took my home made bee robber mix and sprayed the cloth well all over the hive. In the morning, early, I did it again after screening the entrance completely so no bees out that day. I watched throughout the day and the robbing stopped. I left table cloth on and opened the entrance for 2 bee size the next day. Everything fine after that.
Does the wet of a sheet diminish honey smell from inside, I wonder, or is that for weight?
It sounds like you caught it quickly, my bees are now back to normal and entrance population looks the same as usual. We are having very warm weather here and bees are busy with pollen.
Hope yours are ok too.
