I'd've not thought to consider this prior to yesterday (I attended a local seminar on bees and heard there could be issues on this, so I'll ask).
Since I began outside-feeding my bees some time back, I've noticed plenty of yellow jackets all over the feeder at various times. The bees seem to overwhelm them fast, once I pour the syrup onto the "birdbath" [my ad hoc "feeder"]. I've never noticed any YJs flitting around the entrances of my 2 colonies.
SO ..... can the YJs be a problem for my colonies? Can they take over, somehow, and for some reason? Would that be something like SHB or moth conquests (weak hive = opportunities)? Potential disease issues?
Do what people call "yellow bees" = YJs? With these creatures, I've never been attacked by them, even when I walk to the feeder to dump in the bee chow. A few seem to inspect me ("friend or foe?") and then wander away once they're satisfied I'm no problem. I don't have a camera, so can't send an example.
Any thoughts/observations/theories would be appreciated .....
