Hummingbird Nectar FAQ
Everything you need to know about making safe, healthy nectar for your backyard hummingbirds.
The standard and safest ratio for hummingbird nectar is 4 parts water to 1 part white granulated sugar (4:1). This closely mimics the natural sucrose concentration found in the flower nectar they feed on. During cold weather, a 3:1 ratio can provide extra energy, while a 5:1 ratio is sometimes used in very hot weather to prevent dehydration.
Yes, it is highly recommended to boil the water before mixing in the sugar. Boiling helps to dissolve the sugar completely, removes impurities or chlorine from the tap water, and slows down the fermentation process, keeping the nectar fresh for longer. Be sure to let the nectar cool completely before filling your feeder.
You should change the nectar every 2 to 3 days during hot weather (above 25°C / 77°F) to prevent fermentation and mold growth. In cooler weather, you can change it every 4 to 5 days. Always clean the feeder thoroughly with hot water and a bottle brush (no soap) every time you refill it.
Absolutely not. Honey can quickly ferment and promote fatal fungal growth. Brown sugar, raw sugar, and molasses contain iron and other minerals that are toxic to hummingbirds. Artificial sweeteners provide zero calories and will starve the birds. Only use plain, white granulated cane sugar.
Yes, red dye is unnecessary and potentially harmful to hummingbirds. There is no evidence that it attracts them more than the red plastic parts on the feeder itself, and studies suggest artificial dyes could cause kidney or liver issues. The natural nectar is clear, and the red on the feeder is more than enough to attract them.
