What Will Eat From a Hummingbird Feeder?

Bats

• Some bats feed on nectar and sometimes eat from a hummingbird feeder, according to the University of Arizona. These bats include lesser long-nosed bats and Mexican long-tongued bats.

Bees, Wasps and Butterflies

• Bees, wasps and butterflies prefer foods with higher sugar content than the typical sugar solution in hummingbird feeders, but will sometimes gather at and eat from the feeders. A bee guard, a plastic mesh cap that fits over a feeding port, could make it more difficult for these insects to access the sugar solution.

Ants

• Ants that like sweet foods often eat from a hummingbird feeder and have to be kept out. Apply a sticky or greasy substance on the feeder hanger to trap the ants. Otherwise, install a small pool of water or oil around the base of the hanger. This acts as a moat that will keep the ants from reaching the feeder.
