Fruit fly bottle trap

youmagine

I recall coming across the concept of utilizing a paper cone within a bottle to craft an effective trap for fruit flies. Subsequently, I opted to 3D print cones to enhance this idea. To create this trap, start by placing fruit (bananas peels appear to work particularly well) inside a bottle. Next, position one of these printed cones on top. Secure it firmly in place using either glue, tape, or simply cut a hole in the bottle cap and screw it tightly over the trap. As a result, fruit flies are drawn into the cone but are unable to escape.
