1. Using Dirty Feeders
Dirty feeders are a deterrent to hummingbirds. Mold and mildew can make them sick, and nectar that is spoiled or ant-filled is going to make hummingbirds avoid your feeders.
Hummingbird feeders should be cleaned and refilled every 2-3 days at the minimum. Cleaning with hot water and replacing nectar helps keep feeders safe by preventing the growth of bacteria or attracting too many insects like ants and gnats.
One of the reasons you must always clean your feeder is that hummingbirds can catch diseases from a dirty feeder. Hummingbirds themselves are rarely carriers for diseases, but other birds may visit their feeders, and those birds could carry illnesses.
2. Incorrect Sugar Water Ratio
The ratio of sugar to water for hummingbirds is one part sugar to four parts water. That’s ¼ cup of sugar to one cup of water in a homemade mix, or 80% water and 20% sucrose in a commercial mix.
Some people will mix a higher ratio of sugar into their water, mistakenly believing it will be sweeter and attract more hummingbirds. But this can actually make the nectar thicker, like a syrup.
Finally, consider your sugar-to-water ratio. Most hummingbird food recipes call for one part sugar to four parts water.
If your hummingbird food is short on sugar, it could be a less pleasant alternative to regular plants for your feathery backyard friends.
3. Using Food Coloring
There are some concerns about the safety of red food coloring for hummingbirds. Because red food dye hasn’t been proven to be safe, and anecdotal evidence suggests that it might be dangerous, we recommend using clear nectar.
Hummingbirds can find a clear solution just fine. Consider choosing a red feeder or a feeder with red elements on it.
But avoid adding red food coloring to the mixture itself. It’s unnecessary and may pose a risk to the birds.
4. Not Changing Nectar Regularly
Keeping fresh nectar out for your hummers is very important. If the sugar solution sits outside for too many days, especially in hot weather, it will develop mold or go rancid.
Putting fresh food out every couple of days is never a bad thing! However, if you are in the hot days of summer, you should be changing your feeder’s sugar water every two to three days to keep your hummingbirds safe and healthy!

Several things can cause hummingbird nectar to spoil. The biggest culprits are molds, bacteria, and fungi.
You can often spot spoiled, moldy nectar with just a glance. The sugar water solution may turn cloudy, or you may notice mold or mildew growth at the feeder’s base.
5. Placing Feeders in Direct Sunlight
Position feeders in shady areas out of direct sunlight to prevent nectar from overheating and spoiling. Space them apart from each other to avoid territorial behaviors at your feeders.
Direct sunlight all day will cause your nectar solution to ferment faster. The hotter the temperatures, the faster fermentation will occur, and the more often the hummingbird feeder needs cleaning.
Keep your nectar fresh for longer by keeping it in the shade. Don’t place your feeder in direct sunlight; the nectar solution will go bad faster.
But don’t put them in dense shade either; it will be harder for the hummingbirds to spot the feeders that way.
6. Ignoring Ant and Bee Problems

Another reason hummingbirds might avoid your feeders is ant or bee activity. Bee traps and ant moats, built into the design of your feeders, can help you avoid these problems so that only hummingbirds can access the nectar.
The most effective method for most situations is to use a traditional ant moat to keep ants out of hummingbird feeders. An ant moat is a simple reservoir of water that ants cannot cross to reach the reward.
An ant moat will be effective in most locations as long as you keep it filled with water. Bee guards that fit into the feeding ports of existing feeders can also be purchased.
They are a small plastic mesh shape that fits in the opening of the feeder where the bird drinks. The Hummingbird bill can fit through the mesh but the bee cannot get in.
Unfortunately, bee guards donot fit all styles of feeders.
7. Using Metal Feeders
Metal feeders can corrode over time, leaching harmful substances into the nectar. Opt for plastic or glass feeders with non-metallic components to protect the hummingbirds.
This choice ensures that your feeders remain safe and effective for years to come.
8. Using Multiple Feeders Too Close Together
It is also a good idea to place hummingbird feeders. You should place feeders in groups in multiple locations in your garden – ideally not within sight of each other.
There really is no limit to how many hummingbird feeders a person can own. The bigger your yard, the more you can put up.
If you want your hummingbirds to be happy and healthy, it is best to avoid crowding them together.
9. Not Monitoring for Mold
You can store extra hummingbird nectar in a glass jar in the fridge for up to two weeks. But keep an eye on it–if there are any signs of mold, throw it out and start over.
If you want to provide sugar water to hummingbirds, you must do so safely! Feeding hummingbirds is a big responsibility, as feeders are susceptible to bacteria and mold growth.
You absolutely must keep the feeder clean! Bottle brushes are also necessary to get the insides of the nectar holder clean and mold free.
The Hummer’s Galore 2-pack are extra long and would be ideal for cleaning tube feeders as well. (Just be sure to clean the brushes thoroughly to prevent cross-contamination.)
Hummingbird feeder mistakes to avoid
| What you see | Likely cause | What to do |
|---|---|---|
| Hummers leave the feeder | Dirty feeder with mold or ants | Clean and refill every 2-3 days with hot water |
| Thick syrupy nectar | Too much sugar | Use 1 part sugar to 4 parts water |
| Red-colored nectar | Food dye | Use clear nectar and a red feeder |
| Cloudy sugar water | Mold, bacteria, or fungi | Change every two to three days, especially in summer |
| Ants in the ports | No moat | Hang an ant moat filled with water |
| Bees at the ports | Open ports | Add mesh bee guards the bill can fit through |
| Fights at one feeder | Feeders clustered in sight of each other | Hang several, not within sight of each other |
| Mold in stored nectar | Old leftover syrup | Toss fridge nectar at the first sign of mold |
