Bird's Choice Bee Guards eliminate wasted Oriole nectar due to bee and wasp contamination. These easy-to-attach rubber feeding port guards - designed for the Oriole Feeder with Dome and other Oriole feeders - create a barrier that prevents flying insects from accessing and contaminating your Oriole nectar.
Simply place these nectar guard tips on the underside of each feeding port (located under the feeder cover). The flexible membrane in the center of each tip opens easily when an Oriole feeds, but closes when the bird's beak exits the port. Pair Bird's Choice Bee Guards with an ant moat to make your feeder completely insect proof. Each Bird's Choice Bee Guard measures 7/16" dia. 8 pack.
