Hummingbird Feeder – Bee and Wasp Control
Q: How can I keep honeybees from my hummingbird feeders? They are driving the hummers away.
A: You have to modify the feeder opening so that the insect tongues are too short to reach the nectar. These Hummzinger (click for sources) seem to have a good reputation for thwarting bees, hornets and wasps.
