Keeps them Fresh Longer. Nectar Defender works especially well for large hummingbird feeders in warm weather climates. It is an all natural hummingbird feed additive that helps keep your hummingbird nectar of choice fresh in your feeder for weeks, not days. Your hummer friends will come back more often because they enjoy fresh nectar every time they visit your feeder. Spoiled nectar is unhealthy for the birds. Hummingbirds avoid feeders with spoiled nectar, which decreases the birdwatching experience our customers enjoy. There has long been a need for a safe, natural solution to keep the nectar fresh, and solve the problem of rapid spoilage in hummingbird feeders. Nectar Defender contains no artificial preservatives or dyes, just a mineral micronutrient that is part of a hummingbird's natural diet. With this additive to your nectar, it will stay fresh in your feeder for up to 2 weeks, even in hot weather. ## Features - STAYS FRESH LONGER: Nectar Defender maintains nectar in hummingbird feeders for up to 2 weeks - PROTECT HUMMINGBIRDS: Added micronutrient prevents nectar spoilage with zero artificial ingredients - EASY: Add a little to your hummingbird nectar mix, a better alternative than ready to use nectar - HEALTH AND WELLBEING: No dyes or artificial ingredients makes for healthy, happy hummingbirds - HUMMINGBIRD RECIPE: 1 part sugar to 4 parts water, then add a dash of Nectar Defender accordingly ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DH1935S | | Additional Features | Easy-Refill Top | | Best Sellers Rank | #6,592 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #25 in Outdoor Bird Feeder Accessories | | Brand | Sapphire Labs | | Brand Name | Sapphire Labs | | Capacity | 0.11 Liters | | Color | Clear | | Customer Reviews | 4.7 out of 5 stars 1,426 Reviews | | Included Components | 4 oz.
