Why Cleaning Your Feeder Matters More Than You Think

If you love watching hummingbirds, you probably already know the joy of seeing them zip around your garden or balcony. But what you might not know is this: a dirty feeder can do serious harm.

Neglecting to clean your hummingbird feeder doesn’t just make it unappealing—it can make birds sick, or worse.

Here’s why keeping your feeder clean is one of the most important (and loving) things you can do for them:

1. Mold and Bacteria Can Be Deadly

When sugar water sits too long, it ferments and grows harmful mold and bacteria. This can cause fungal infections in hummingbirds, especially around their beaks and tongues, which can be fatal.

Solution: Clean your feeder thoroughly every 2 to 3 days in hot weather, and at least once a week in cooler temperatures.

2. Cloudy Nectar = Spoiled Nectar

If your nectar starts to look cloudy or smells sour, it’s already gone bad. Even if the feeder looks clean from the outside, bacteria could be lurking inside.

Tip: Rinse with hot water and use a bottle brush to scrub the feeder thoroughly. Avoid soap, as it can leave harmful residues.

3. Clean Feeders Attract More Birds

Hummingbirds remember where they find safe, fresh food. A clean feeder with fresh nectar becomes a trusted stop—meaning more frequent visits from your tiny friends.

4. It’s a Simple Act of Kindness

Hummingbirds give us beauty, wonder, and joy. Keeping their feeder clean is an easy way to return the favor.

Think of it as hospitality: you wouldn’t serve guests from a dirty cup, and the same goes for your hummingbird visitors.


Keeping your feeder clean doesn’t take long, but it can make all the difference. It keeps hummingbirds healthy, encourages return visits, and shows respect for the wild lives we invite into our spaces.

So before you refill that feeder, give it a good scrub. Because a clean feeder isn’t just good practice—it’s good love.
