How to prevent mold from taking over your hummingbird feeder

Mold is very bad in hummingbird feeders. Remember to change the nectar in your feeder every 2-4 days, regardless of whether the nectar has been used. In hot, humid weather you might even have to change the nectar every other day.

I find the more often I change the nectar the easier it is to maintain the feeder. You won't be battling any black mold and you'll have a lot more hummingbirds and orioles.

I usually just rinse the feeder with hot water. 
To clean the hard to reach places you can use a pipe cleaner or we have special little brushes for cleaning feeders at Wild Birds Unlimited.

Now that we are in the hot and humid weather, you should soak the hummingbird feeder for about 5 minutes in a Scoot, active enzyme cleaner once a week. Or use a one part vinegar to nine parts water solution to clean the feeders. Then rinse your feeders thoroughly.

Also make sure your nectar solution is the proper proportion.

also boiling( 5 min rolling boil) then cooling the nectar will reduce fermentation in the feeder!

Caring For Those Who Can't Care For Themselves.. Thank you so much for posting very valuable information on caring for the hummingbird feeders! For people who like to have those beautiful birds to come each year and get the nectar they need to survive, this blog gives the much needed added care for these beautiful birds by feeding them with the care and quality they cannot do for themselves. Thank you once again! Hopefully this will bring many more happy and healthy birds to my relative's porch. : )
