Hang this cute ant moat to keep ants out of the sweet nectar of your hummingbird feeder! Whimsical upside-down umbrella design adds a note of charm to your bird feeding station and does double-duty as an ant deterrent. Hang the umbrella and fill with water. Pesky ants can't swim, so they avoid the water and leave a plentiful supply of nectar for your hummingbirds. Hang the hummingbird feeder from the lower hook of the umbrella.
