I pulled honey supers two weeks ago. Last week I dropped the empties back in. All the while the bees weren't too distracted by me. Yesterday I pulled the cover and blew a whiff of smoke near the top of the inner cover. The bees went nuts and started attempting to sting me and the smoker. I soldiered through and pulled a few of previously extracted super frames. Since returning the frames the bees have started to refill them. If they are bringing in nectar and pollen, and were docile when I got in there mid last week, what gives? Temps are steady in the 80s, it wasn't raining, and it was later in the day. 2 of my remaining 3 hives were also agitated. I don't remember my bees getting this fussy until Sept or later last year. Northeast Ohio and we have golden rod starting to open up as I type this. Any ideas?
