Making your own hummingbird food is cheaper, safer and better than store-bought — and it takes about two minutes with two ingredients you already have: plain white sugar and water. Here is the simple recipe, plus the few important rules that keep hummingbirds safe.
The hummingbird food recipe
Mix 1 part plain white sugar with 4 parts water. That 4-to-1 ratio closely matches the natural sugar level of the flower nectar hummingbirds feed on. For example:
- 1 cup water + ¼ cup sugar
- 2 cups water + ½ cup sugar
- 4 cups water + 1 cup sugar
Stir until the sugar is fully dissolved, let it cool to room temperature, and fill your feeder. That is all a hummingbird needs — no colouring, no supplements, nothing else.
Do you have to boil it?
No, boiling is not required — the sugar will dissolve in warm tap water on its own. Some people briefly boil the water because it can help the nectar stay fresh a little longer, but if you do, let it cool completely before filling the feeder. Warm tap water plus a good stir works just as well.
What never to add
A few common additions are genuinely harmful, so keep the recipe to just sugar and water:
- No red dye or food colouring. Hummingbirds are drawn to the red parts of the feeder itself, not the liquid, so dye is unnecessary — and it may be harmful. The nectar should be clear.
- No honey. Honey ferments quickly and can grow a mould that causes a deadly fungal infection in hummingbirds.
- No brown sugar, raw sugar or "natural" sugars. These contain iron and other compounds that are bad for hummingbirds. Only plain white granulated (table) sugar is safe.
- No artificial sweeteners. Hummingbirds need the real calories from sugar for energy; sweeteners give them none.
How often to change the nectar
Hummingbird food spoils, especially in heat, so change it regularly and rinse the feeder each time:
- Mild weather: replace every 3–5 days.
- Hot weather (about 90°F / 32°C or above): replace every 1–2 days.
If you ever see cloudiness, black spots (mould) or a fermented smell, empty and clean the feeder straight away — spoiled or mouldy nectar can make hummingbirds ill. You can make a batch ahead and keep spare nectar in the fridge for up to about a week.
