The main idea is to reuse the 1.9L vials as an insect trap.
The adapter is simply screwed in place of the measuring cap.
The proposed model has a screw thread adapted to the bottle as well as an internal cone with an end measuring 9mm.
Several 1mm holes are placed along the cone to spread the aromas of the attractant more easily.
Other holes are placed on top to attach a string.
The model is designed in such a way that no support wire is used.
