This is the first time I've had a problem with bees swarming my Hummingbird feeders. These new feeders this year do not have the "bee guard".
I've tried spraying PAM on the feeder and that helped a little but the bees continue to swarm the feeders and I've seen them running the Hummingbirds off!
I've also had the Finches trying to command the feeders and cutting off the foot rail and spraying PAM seemed to take care of them. (They have their own feeders)
Any other ideas? Don't want to eliminate the bees, they're too beneficial, just don't want to lose my Hummingbirds.
