Aspects Nectar Guard Tips

The HummZinger® Nectar Guard® Tips easily slide onto the feeding ports on the underside of the feeder cover. Each one uses a flexible center membrane that opens when a hummingbird inserts its beak and closes when the beak is removed. This creates a barrier that helps keep flying insects from accessing the nectar while maintaining clear feeding access for hummingbirds. The set is designed for easy installation and includes a one year guarantee.
