Instructions: Stir sugar into water until dissolved. No need to boil. Cool before filling feeder. Store extra in the fridge for up to 2 weeks.

Step-by-Step Instructions

Five minutes is all it takes.

1

Measure water

Tap water is fine. Use the batch sizes table above or the calculator to determine how much you need.

2

Add sugar

Use plain white granulated sugar only. Measure ¼ cup sugar for each 1 cup of water.

3

Stir until dissolved

Stir or shake until the sugar is fully dissolved. No need to heat the water (see below).

4

Cool completely

If you heated the water, let the nectar cool to room temperature before filling your feeder.

5

Store extras

Refrigerate unused nectar in a sealed container for up to 2 weeks.

Do I Need to Boil the Water?

Short answer: No.

The Smithsonian National Zoo's official guidance is that the water does not need to be boiled. Just stir or shake your mixture until the sugar is fully dissolved.

Why some people boil anyway:

  • Removes chlorine (minimal benefit)
  • Helps sugar dissolve faster
  • May slightly extend shelf life (debated)

Any bacteria introduced during mixing will be overwhelmed by the high sugar concentration. Since you're changing nectar every 2-3 days in summer anyway, boiling provides negligible benefit.

What NOT to Use

These ingredients can seriously harm or kill hummingbirds. Use only plain white sugar.

Ingredient Why It's Harmful
Red dye Unnecessary (feeder color attracts birds) and potentially harmful — no studies prove safety in hummingbirds.
Honey Promotes fatal fungal growth (Candida); ferments rapidly; can contain botulism spores.
Artificial sweeteners No nutritional value; birds may starve while feeling full.
Brown / raw / organic sugar Contains iron and other minerals that can be harmful to hummingbirds in high concentrations.
Powdered sugar Contains cornstarch and anti-caking agents.
Corn syrup Wrong sugar type; not what hummingbirds evolved to digest.
Fruit juice Ferments quickly; attracts insects; unnecessary.

Why Plain White Sugar?

Pure Sucrose

White granulated sugar is pure sucrose, the same sugar found in flower nectar. Hummingbirds have evolved specifically to digest sucrose efficiently.

No Iron Overload

"Raw" or "organic" sugars contain iron and molasses residues. Hummingbirds cannot process excess iron, which can accumulate and cause organ damage over time.

When to Change Your Nectar

Nectar spoils faster in warm weather. In the Southeast's hot summers, you may need to change nectar every day or two. Use the interactive tool to find out the right schedule for your current temperature.

Signs Nectar Has Gone Bad

Change your nectar immediately if you notice any of the following:

  • Cloudy appearance
  • Floating particles
  • Black mold spots
  • Fermented or sour smell
  • Stringy residue in feeder

When Should I Change My Nectar?

Nectar spoils faster in warm weather

78°F

Every 4–5 days

At 70–80°F, change your nectar every 4–5 days.

Signs nectar has gone bad: cloudy appearance, floating particles, black mold spots, fermented smell, or stringy residue. Change immediately if you see any of these.
