So about 4 weeks ago I noticed a huge loss of bees outside the hive. I rarely see any dead bees, and now the ground was just covered in them. I did a little inspection, never found the queen, but there still seemed to be a lot of bees in the hive. I did notice that activity outside the hive since then was greatly reduced. 2 weeks ago I did another inspection and was going to get the hive ready for winter. Stores looked good, bees were pretty defensive though. Early this week there was hardly any activity outside the hive, and barely any inside. So today i did a full inspection, nothing. No queen, few bees trying to raise a queen, mostly robbers in the hive I think.
So what went wrong? Why such a huge sudden die off. I have hundreds of yellow jackes, hornets around as well, could they have gone in and killed the hive? My entrance reducer is 3-4 inches (now 1").
I think its too late to save this hive! But any advice for next year is greatly appreciated!
