>>1065016If you purchase a feeder, look for one with a good guard screen to keep out insects. If you make a feeder, make sure to get some aluminum/nylon screen to make a guard. Use a toothpick to shove into a few spots in the screen to widen it for the bird beaks. It is the distance between the entrance and the water that makes all the difference. It needs to be longer/thicker than what the insects can reach with their tongues.
So long as the feeder is properly level, not leaking, and has a guard screen there should not be a problem with wasps and bees.
