The window fly trap is a glue-coated sticker for catching flies. It works by taking advantage of the natural behavior of flies. Attracted by heat and sunlight, flies like to stay close to windows, being attracted to the trap by the monochromatic pattern it presents, clinging to the sticky surface with glue. If placed in areas close to infested areas (e.g. fruit trees), the window sticker can also be used to catch fruit flies.
