Ant-Foil® is a patented non-toxic ant barrier that conveniently keeps ants out of your hummingbird and oriole feeders.


The Ant-Foil® ant-barrier is a new, patented product designed to prevent ants from contaminating your hummingbird and oriole feeders – U.S. Patent 7,793,461. The Ant-Foil® is a very convenient, 100% non-toxic alternative to insecticide barriers and the old style, water moat ant traps that require frequent (sometimes daily) refilling and routine unpleasant cleaning.


The Ant-Foil® product is designed to use a non-toxic, patent pending Green-Glue™ adhesive that provides months of ant-barrier protection with a single application. The Green-Glue™ is not water-soluble and it will not run or drip in very hot weather conditions. The Ant-Foil™ is supplied with enough Green-Glue™ to extend the service life of this ant-barrier to many feeding seasons.
