- Product Review (submitted on April 8, 2019):
I've been using these things for years and years and absolutely love them. They work like magic to keep ants away from your hummingbird or oriole feeders. You don't have to make sure to keep water in them like moat types of deterrents -- they are set-and-forget. And they last for several years. I would think the active ingredient would peter out, but I have some that are still going strong after at least five years. I'm not crazy about the red color so I usually spray paint mine a nice copper or bronze, which adds a touch o' class to the garden. My only complaint is they are a bit on the pricey side, but otherwise, a welcome addition to our yard.
