Aspects Nectar Guard Tips
Prevents bees and wasps from contaminating nectar. They easily slide onto the feeding ports on the underside of the feeder cover. The flexible membrane in the center of the tip easily opens when hummingbirds insert their beaks to feed and close up tight when beaks are removed. Nectar Guard tips create a barrier flying insects can't penetrate. The tips also prevent rain water from diluting your nectar.
