An essential accessory for keeping ants out of nectar feeders. Just fill with water, hang it above the feeder and ants will be trapped in the water instead of being able to make their way down into your hummingbird or oriole feeder. We like this ant moat because its deep reservoir keeps water from evaporating as quickly as other smaller ant moats. The red color also helps attract hummingbirds to the feeder. Comes with additional s-hook.
