Yes, according to the manufacturer: Aspects Nectar Guard Tips are built to block bees, wasps, and other flying insects from reaching the nectar while still letting a hummingbird feed normally. The tips use a flexible membrane that opens for a hummingbird's thin beak and closes against the wider mouthparts of an insect, though the product's own listing offers no independent test data behind that claim, and at least one customer reports removing the tips because their hummingbirds had trouble feeding.
How Do Nectar Guard Tips Work?
Aspects Nectar Guard Tips slide onto the feeding ports on the underside of a compatible feeder's cover. Each tip has a flexible membrane at its center that opens when a hummingbird inserts its beak and closes again once the beak is removed, which is designed to create a barrier that keeps flying insects from reaching the nectar inside.
Which Feeders Work With Nectar Guard Tips?
Aspects Nectar Guard Tips fit the HummZinger Ultra 12oz, the HummZinger Fancy Little 8oz and 12oz, the HummZinger HighView Mini 8oz, 12oz, and Excel 16oz, and the HummBlossom Rose and Plum feeders. They are not compatible with the HummZinger Excel 16oz, so check your feeder's exact model before buying a pack.
Does the HummZinger Ultra Already Include Bee Guards?
Yes. The HummZinger Ultra 12oz hummingbird feeder ships with Nectar-Guard tips already installed on its feeding ports, and its product listing states the tips are meant to prevent bees, wasps, and other flying insects from contaminating the nectar.
Do Nectar Guard Tips Affect How Hummingbirds Feed?
They can, for some birds. At least one customer review on the HummZinger Ultra's product page describes removing the tips because the hummingbirds visiting their feeder weren't feeding with the tips in place. If you notice fewer visits after installing nectar guard tips, removing them to see whether activity picks back up is a reasonable test.
Does Anything Keep Ants Off a Hummingbird Feeder Too?
Nectar guard tips are built for flying insects, not crawling ones. The HummZinger Ultra addresses ants separately with a built-in ant moat, which its listing describes as blocking crawling insects from reaching the nectar, a different mechanism from the flexible tips on the feeding ports.
Frequently Asked Questions
How Much Do Aspects Nectar Guard Tips Cost?
$8.95 CAD for a pack of 12 tips.
Can I Add Nectar Guard Tips to Any Hummingbird Feeder?
No. They're designed for specific Aspects feeder models, including the HummZinger Ultra, HummZinger Fancy, HummZinger HighView, and HummBlossom lines, and they aren't compatible with the HummZinger Excel 16oz.
What Should I Do If Nectar Guard Tips Stop Hummingbirds From Feeding?
Try removing the tips and watching whether feeding activity returns to normal, since at least one customer reported this exact issue with their feeder.
Does the HummZinger Ultra's Ant Moat Come Separately From the Nectar Guard Tips?
No. The HummZinger Ultra 12oz includes both features built into the same feeder: Nectar-Guard tips on the feeding ports for flying insects and an ant moat for crawling insects.
Is There Independent Testing Behind the Nectar Guard Tips' Insect-Blocking Claim?
The product's own listing doesn't cite independent test data; it states only that the tips create a barrier flying insects can't penetrate, which is a manufacturer and retailer claim rather than a third-party verified result.
