Common hummingbird feeder challenges and solutions

Setting up a nectar feeder is one of the simplest ways to attract hummingbirds to your yard. Being a responsible hummingbird host can sometimes come with challenges, so we’ve put together the solutions to some of the most common hummingbird feeder questions to help you get the most out of your hummingbird feeder!

Why aren’t the hummingbirds coming to my feeder?

There are a few different factors that could be causing a hummingbird to choose a different source of food. Hummingbirds are migratory birds, meaning they leave and return from a specific area seasonally. As they return from migration and end up in their ultimate destination, they will remember the source of their first meals - oftentimes coming back to the same feeders repeatedly. For the best chance of hummingbirds discovering your feeder, it is recommended to have it up and ready before they return from their winter migration. Be sure to research the migratory pattern of hummingbirds in your area to make sure you haven’t put your feeder out too late, since this can cause them to overlook it later in the season.

One thing to keep in mind is that all birds are creatures of habit. They may be hesitant to try out a new feeder, especially if you have been offering nectar in other feeders – a tried and true food source. It could also take some time for the hummingbirds to get used to a new landing pattern or learn the mechanics of drinking from a new feeding port. It may take several weeks before the hummingbirds find and begin feeding regularly from a new feeder. Before making any changes, try waiting at least two weeks to give them enough time to discover your feeder.

Here are some more tips to help attract birds to your hummingbird feeder:

  • Take down other feeders: Hummingbirds may prefer to feed from dependable food sources like existing feeders. If you have other nectar feeders in your yard, try temporarily taking them down until the hummingbirds find and use the new feeder. Once they are regularly using the new feeder, existing feeders can go back up.
  • Increase the sugar content: Try slightly increasing the sugar content of your nectar. This will immediately reward the hummingbirds for visiting your feeder and encourage them to come back. Once until the hummingbirds are regularly drinking from your feeder, you can then lower the water to sugar ratio back down to the recommended 4:1.
  • Keep it clean: It is recommended nectar feeders be cleaned at least every 4-5 days. To clean, take down your feeder and discard any unconsumed sugar water. Take apart your feeder and flush it with warm water. You must also change the nectar frequently - at least twice a week. If you notice that the nectar is turning milky, or that white strings or black spots are growing in it, change it more often. If you notice any mold, take down the feeder immediately, give it a thorough cleaning and follow the steps below to prevent mold growth on your feeder.
  • Change locations: Placing feeders near flower beds or planters may naturally attract more hummingbirds to your feeder. Feeders should be hung or mounted closer than 3 feet from a window or farther than 15 feet from a window to help prevent fatal window collisions.

What should I put in my hummingbird feeder?

The formula for hummingbird food is simple: about one part white granulated sugar to four parts water. Boil the water for approximately 2 minutes, add the sugar, and stir to dissolve thoroughly. We do not recommend adding red dye to the nectar mixture. Cover and allow the nectar to cool before using or pouring into a clean storage bottle. A large batch of nectar can be made and stored in the refrigerator for up to two weeks. This makes refilling the feeder easy so you won't mind doing it every few days.

How do I keep mold from growing on my hummingbird feeder?

It is inevitable that sugar water will eventually break down and cause mold, fungus, or other harmful bacteria to grow inside of a hummingbird feeder. To prevent mold growth, hummingbird feeders should be taken down and cleaned at least every 4-5 days. To clean, take down your feeder and discard any unconsumed sugar water. Take apart your feeder and flush it with warm water. If mold is present, you can sanitize the feeder by placing all dishwasher-safe parts in the dishwasher for a thorough cleaning. If washing by hand, soak and clean the feeder thoroughly with a solution of ¼ cup bleach to one gallon of water. Rinse thoroughly and allow to dry completely before refilling.

Since mold growth can be accelerated by heat, especially in the warmer summer months, try keeping your feeder in a shaded area. Keeping the nectar cool helps to delay fermentation which is the process that causes nectar to spoil and mold to grow.

How do I prevent bees at my hummingbird feeder?

Bees, wasps, and hornets are hardly welcome guests at any feeder and can be harmful to hummingbirds if stung. Typically, if bees don’t have access to the nectar, they should eventually move on from the feeder to a more rewarding source. Here are some additional tips to help deter the bees:

    • Keep it clean: Make sure there is no exposed nectar on or around the outside of your feeder and thoroughly clean it with warm soapy water every 4-5 days at minimum.
    • Change it up: Periodically move your feeder. Birds will usually look around and find a relocated feeder, but insects will not.
    • Lower the nectar level: If using a dish style feeder, try decreasing the amount of nectar in your in the dish to keep it lower than the feeding ports. This will make it more difficult for bees to reach. Keep in mind that a hummingbird’s tongue is twice as long as its beak so it can easily reach near the bottom of the dish.
    • Get in the shade: If the feeder is currently in the sun, try moving it to a more shaded area.

How do I keep ants off my hummingbird feeder?

Although hummingbirds do eat insects, they do not eat ants. The presence of ants on your hummingbird feeder can prevent them from using it, or the ants may enter the feeder and contaminate the nectar which can be harmful to hummingbirds. Here are some ant-proofing tips to try:

  • Use an ant moat: Many hummingbird feeders have built-in ant moats, which trap ants in a small cup of water before they have the opportunity to reach the feeder. If your feeder does not come with an ant moat, you may choose to purchase one separately. Be sure to keep it full of water! If the weather is particularly hot and the water is evaporating quickly, check it regularly to prevent it from sitting empty.

  • Change it up: Periodically move your feeder. Birds will usually look around and find a relocated feeder, but insects will not.
  • Get in the shade: If the feeder is currently in the sun, try moving it to a more shaded area.
  • Try fishing line: You may try hanging your feeder using fishing line, as it is very difficult for ants to climb. Keep in mind this may not be feasible for heavier feeders.

    Hi Mary! Hummingbirds do remember and visit the same feeders repeatedly but can be encouraged to use new feeders, too. Have feeders up and ready about two weeks before they typically return from their winter migration. Happy birding!

    Purchased a new feeder this year. Hummingbirds have come back to the old feeder for years. Should I put the old feed out also so they can find their way here?

    Hi Kathy,
    Thanks for reaching out to Nature’s Way. From what we have researched, air locks form for a few different reasons:
    - In hot weather, the sugar water can be affected by the heat in the feeder which can cause air to form inside
    - When birds suck nectar out, it is possible that they can cause air to go in and this can cause an air lock
    - Some people have found that knocking or tilting the feeder will release the air lock and allow the birds to feed
    Have you been having hot weather lately? Perhaps it is only a matter of waiting for a bit of a cool-down or even testing the feeder indoors to see if it is indeed the weather vs. the bird behavior. All the best.

    I clean my feeders daily. There is no reason that I can find as to why suddenly my feeders are getting “air locked” several times a day.
    Everything I read says “this is a rare thing to happen”. That my be so, but is suddenly very common at my house.
    Only thing I find as a solution is to clean the feeder. My feeders are cleaned daily.
    Is there anything else that i can do to prevent this from happening? I have been using these feeders for years and never had an issue before this year. (actually, this started just 2 days ago).

    I would like to replace the bottom portion of my hummingbird feeder. The previous feeder had plastic flowers the new feeders have silicone flowers. Is that possible.
