Aspects 384 Nectar Guard Tips, Clear, 2 Inch, Replacement Bee Guards for Hummingbird Feeders

Nectar Guard tips easily slide onto the feeding ports on the underside of the feeder's cover. The flexible membrane in the center of each tip easily opens when hummingbirds insert their beaks to feed and closes up tight when beaks are removed. These create a barrier that flying insects can't penetrate. Nectar Guard Tips work with the following products: HummZinger Ultra 12 ounce, Little Fancy 8 ounce, HummZinger Fancy 12 ounce, HighView Mini 8 ounce, HighView 12 ounce, HighView Excel 16 ounce HummBlossom-Rose, HummBlossom-Plum
