Hummingbird Protein Feeder - Just add bananas!
How the Humm-Bug works:
1. Place 2-3 bananas, opened but still with the peel, in the feeder to attract fruit flies.
2. Fruit flies lay thousands of eggs on the bananas.
3. In 7-10 days, the Humm-Bug provides the hummingbirds with a constant source of protein. They will gather round the feeder to eat the fruit flies.
