Amazon Review May 08, 2014

If you have ants constantly getting into your hummingbird feeders, this is for you. I was ready to wage war on the ants, but this did it for me. I tested it out by placing it over one hummingbird feeder and within 24 hours they were all over the other feeder. When I placed the other one on the other feeder, all of the ants were gone. It really works.

We purchased these last year and replacements this year. These worked immediately and within days there were no ants on our hanger S-hooks much less the feeder.
