Tempting Bees?
Hummingbirds lap up nectar when they eat which may cause a small amount of liquid to drip on the surface of the feeder, especially around the ports. Bees find those sweet drips! Avoid tempting the bees by wiping feeder ports and surfaces each day.

"This morning I woke up and discovered HUNDREDS of yellow jackets swarming around my feeders on the patio. I can't sit out there and the poor hummingbirds cannot eat. So distressing!"
