Supplies Needed for Cleaning a Hummingbird Feeder

White Distilled Vinegar

White distilled vinegar is an essential ingredient for cleaning your hummingbird feeder. It is a natural and effective cleaning agent that helps remove mold, mildew, and other buildup from the feeder. Vinegar also helps prevent the growth of harmful bacteria that can be detrimental to the health of hummingbirds.

You can easily find white distilled vinegar at your local grocery store.

Bottle Brush or Pipe Cleaner

A bottle brush or pipe cleaner is another important tool for cleaning your hummingbird feeder. These long, narrow brushes are designed to reach deep into the feeder’s small crevices and remove any residue or debris.

Ensure that the brush or pipe cleaner is specifically made for cleaning feeders to avoid scratching or damaging the feeder’s surface.

Dish Soap

Dish soap is commonly used to clean various household items, and it can be useful for cleaning your hummingbird feeder as well. Choose a mild dish soap that is free of harsh chemicals and additives. Mix a small amount of dish soap with warm water to create a soapy solution for cleaning the feeder.

Baking Soda

Baking soda is a versatile and natural cleaning agent that can be used to clean your hummingbird feeder. It helps remove tough stains and odors, leaving your feeder clean and fresh. Create a paste by mixing baking soda with water and apply it to any stubborn stains or residue.

Let it sit for a few minutes before rinsing it off.


Water is a crucial component for cleaning your hummingbird feeder. It is used to rinse off the cleaning solutions and remove any remaining residue. Ensure that the water you use is clean and free of contaminants to maintain the feeder’s hygiene.

Small Bucket or Basin

A small bucket or basin is necessary for soaking and rinsing your hummingbird feeder. Fill the bucket or basin with warm water and add the cleaning solution of your choice. Place the feeder inside and let it soak for a few minutes.

Use the water in the bucket or basin to rinse off the feeder after cleaning.

Remember to follow the manufacturer’s instructions for cleaning your specific hummingbird feeder model. Regular cleaning and maintenance of your feeder will help ensure the health and well-being of the hummingbirds that visit your yard.

Step-by-Step Guide to Cleaning a Hummingbird Feeder

Step 1: Disassemble the Feeder

Before cleaning your hummingbird feeder, it’s important to disassemble it completely. Remove any perches, feeding ports, and lids from the main body of the feeder. This will make it easier to clean every part thoroughly.

Step 2: Make a Cleaning Solution

To create a cleaning solution for your hummingbird feeder, mix one part white vinegar with four parts hot water. The vinegar will help to remove any mold or bacteria that may have formed inside the feeder. Avoid using soap or bleach, as these can be harmful to the hummingbirds.

Step 3: Soak the Feeder

Place all the disassembled parts of the feeder into a container filled with the cleaning solution. Ensure that every part is completely submerged. Let the feeder soak for at least 15-20 minutes. This will help to loosen any dried nectar or debris.

Step 4: Scrub the Feeder

After the feeder has soaked, use a small brush or bottle brush to scrub each part thoroughly. Pay special attention to the feeding ports and other hard-to-reach areas where mold or bacteria may be present. Rinse the parts with clean water after scrubbing.

Step 5: Rinse Thoroughly

Once you have finished scrubbing, rinse all the parts of the feeder with clean, running water. Make sure to remove any leftover cleaning solution or debris. This will ensure that the feeder is safe for the hummingbirds to use.

Step 6: Air Dry and Reassemble

After rinsing, place all the cleaned parts of the feeder on a clean towel or paper towel to air dry. Make sure that each part is completely dry before reassembling the feeder. Once dry, put the feeder back together, refill it with fresh nectar, and hang it in your garden for the hummingbirds to enjoy.

Cleaning your hummingbird feeder regularly is essential for the health and well-being of the hummingbirds. By following these simple steps, you can ensure that your feeder is clean and safe for these beautiful creatures.

Remember to clean your feeder at least once a week or more frequently during hot weather to prevent the growth of mold or bacteria.

How Often to Clean a Hummingbird Feeder

Keeping your hummingbird feeder clean is essential for the health and well-being of these beautiful creatures. Regular cleaning not only ensures that the nectar remains fresh, but it also helps prevent the growth of harmful bacteria and mold.

Here are some guidelines on how often you should clean your hummingbird feeder:

Every Time You Refill

It is recommended to clean your hummingbird feeder every time you refill it with fresh nectar. This practice helps maintain the feeder’s cleanliness and prevents any residue or mold from contaminating the new batch of nectar.

Cleaning the feeder before each refill ensures that the hummingbirds have access to a clean and safe food source.

Every 2-3 Days in Hot Weather

In hot weather, the nectar in your hummingbird feeder can spoil more quickly. The warm temperatures create an ideal environment for bacteria and mold growth. To prevent this, it is advisable to clean your feeder every 2-3 days during hot weather.

This frequency ensures that the nectar remains fresh and free from any potential health hazards for the hummingbirds.

When Mold is Visible

If you notice any signs of mold or mildew inside your hummingbird feeder, it is crucial to clean it immediately. Mold can be harmful to hummingbirds, causing digestive problems and even death. To clean the feeder, disassemble it and soak the parts in a solution of one part white vinegar to four parts water.

Scrub away the mold with a bottle brush, rinse thoroughly, and refill with fresh nectar.

Before Storing for the Winter

Before storing your hummingbird feeder for the winter months when the hummingbirds have migrated, it is essential to give it a thorough cleaning. Even if there is no visible mold or residue, bacteria can still be present.

Disassemble the feeder, clean all parts with warm soapy water, rinse thoroughly, and allow them to dry completely before storing them in a clean and dry place. This extra step ensures that your feeder will be ready for the next hummingbird season.

Remember, maintaining a clean hummingbird feeder is not only beneficial for the birds but also a great way to enhance your birdwatching experience. By following these cleaning guidelines, you can create a safe and inviting environment for these delightful creatures to enjoy.

Tips to Discourage Mold Growth

Use Fresh Nectar

One of the best ways to prevent mold growth in your hummingbird feeder is to use fresh nectar. Hummingbirds are attracted to the sweetness of the nectar, but so are mold spores. When the nectar sits in the feeder for too long, it becomes a breeding ground for mold.

By making fresh nectar regularly, you can ensure that the feeder remains clean and mold-free. Remember to use a 4-to-1 ratio of water to sugar when making the nectar.

Don’t Let Nectar Sit for More Than a Few Days

Hummingbird nectar should not be left sitting in the feeder for more than a few days. As mentioned earlier, the longer the nectar sits, the higher the chances of it developing mold. It is recommended to change the nectar every 2-3 days, especially during warmer weather when mold growth is more likely to occur.

By staying diligent in replacing the nectar regularly, you can prevent mold from taking hold in your feeder.

Change Nectar if Cloudy or Slimy

If you notice that the nectar in your feeder has become cloudy or slimy, it is a clear sign that mold has started to grow. It is crucial to immediately change the nectar and thoroughly clean the feeder to prevent further mold growth.

Cloudy or slimy nectar is not only unappetizing to hummingbirds but can also be harmful to their health. By keeping a close eye on the condition of the nectar, you can ensure a healthy feeding environment for these beautiful birds.

Rinse with Vinegar Weekly

Regularly rinsing your hummingbird feeder with vinegar can help prevent mold growth. Vinegar has natural antibacterial and antifungal properties that can inhibit the growth of mold spores. To clean the feeder, simply disassemble it and soak the parts in a solution of one part vinegar to four parts water for about 15 minutes.

Afterward, scrub the feeder with a bottle brush, rinse it thoroughly with clean water, and refill it with fresh nectar.

Use Bleach Solution Monthly

Using a bleach solution to clean your hummingbird feeder once a month can be an effective way to eliminate any lingering mold spores. Mix one part bleach with nine parts water and soak the feeder parts in the solution for about 15 minutes.

Scrub the feeder with a bottle brush to remove any remaining mold or residue, rinse it thoroughly with clean water, and let it air dry before refilling it with fresh nectar. Be sure to rinse the feeder well to remove any traces of bleach before refilling.

By following these tips, you can discourage mold growth in your hummingbird feeder and provide a clean and healthy environment for these enchanting creatures.


With the right supplies and techniques, cleaning your hummingbird feeder doesn’t have to be a dreaded chore. In fact, it’s an essential act of care that will keep your feathered friends healthy and happy.

Be sure to fully disassemble, scrub, and rinse your feeder at least every time you refill it. For spotless results, let it soak in a vinegar solution before scrubbing. With a thorough cleaning routine, you can enjoy watching hummingbirds feed at your feeder without worries.
