The best way to keep the pesky little ants from climbing up and into your feeders! Simply hang the ant moat from a hook and then attach the bird feeder below. Be sure to fill it up with water during the dryer months, and the ants will not be able to get down and into your feeder. The polished red metal coordinates nicely with most of our feeders, especially the red coloured options. High capacity, measures 8.89cm x 6.35cm(3.5" x 2.5").
