I heard the fat bee man say recently to really watch the beetles in September. Is that simply because they've had all summer to populate and are at their peak? Or is there something about the end of summer that they get a boost by a honey flow or something.
I had the very unfortunate event of going to help a friend with his hive this evening only to find them slimed out. I have also lost two seemingly strong colonies in the last two weeks to the beetles.
I refuse to use chemicals as I'm just one of those hard headed types. I can try crowding the bees, which I've been doing a little in preparation for winter, but don't want to overcrowd as we still have a fall flow coming. I have some hives that appear loaded with beetles, but others that don't have hardly any. I know that could be hygenic behavior and am taking note of it. Or it could be placement in the bee yard ( more shading compared to others?). I've heard old timers recommend placing hives in full sun, but it gets so blasted hot down here in the summer I fear that could actually be more stressful!
I'd like to start some good discussion on this so others don't have to take the losses I have!
