Bẫy ruồi cho hũ Nutella/Nutoka

If you want to catch flies- either to get rid of them on one spot in the garden or you need some for fishing as bait- and have a spare empty small Nutella (or similar) glass, this is the print you  are are looking for.

The choice of attractant will determine wether you catch the flies alive or not: Sugarwater will drain the flies while rotten fuit pieces just trap the flies and keep them alive.

The flies will be attracted by the odors of the attractant and crawl into the glass. They likely will not be able to escape through the small hole.

Although not very scientific: I have observed, that light colors (particularily yellow and orange) seem to be more effective in attracting flies. However, the sample size of my observation is pretty small.

Printing Instructions

Just print upside down (the large opening facing the print plate). No special settings required.
