How to Prevent Mold and Bacteria in Hummingbird Feeders

Hummingbirds are fascinating creatures to attract to your yard, but their specialized feeders can be annoying to maintain. Hummingbirds feed on nectar or a solution of sugar water which will quickly spoil in the summer heat.

Spoiled nectar or sugar water can grow both mold and bacteria. This is not only ugly, it is dangerous to the birds. Fortunately, hummingbirds are smart enough to avoid moldy feeders. Here are some steps you can take to keep your hummingbird feeders clean and prevent mold and bacteria growth.

Difficulty: Easy

Instructions

1. Prevent hummingbird feeders from spoiling by hanging the feeders in a shady location. Feeders can be hung with suction cups to windows under a porch or awning. This will both provide shade for the nectar and bring the hummingbirds close for observation.

2. Keep away mold and bacteria by frequently cleaning the feeders. In the heat of summer, feeders should be changed at least once a week, if not more often. Rise the hummingbird feeders out before they show signs of mold (black specks) to keep cleaning easy.

3. Select a hummingbird feeder that is easy to take apart and clean. If your feeder is easy to maintain, you will be more likely to do it frequently and thoroughly. Choose a feeder with a wide mouth and dishwasher safe parts for the easiest maintenance. Clean the feeder at night when the birds aren't feeding.
