The Garbage Can Fly Trap allows users to discretely catch and eliminate house flies and fruit flies from kitchens, homes and outdoor areas. The trap doesnât require chemical attractants, the use of unsightly flypaper, or chasing flies with a swatter. When full, the replacement cartridge can be released directly into your garbage via a quick release button on top of the trap allowing for hands-free disposal so thereâs nothing disgusting to touch. 1.5′ hole saw required for installation (not included). For use in plastic or metal garbage can lids. Patent Pending.
