Dry soda bottle fly trap

The ultimate goal is to create something that mimics the effectiveness of the following website: https://entomology.ca.uky.edu/ef010. To achieve this, a trap must be designed with a cone-like structure placed over some bait, drawing flies upwards by light towards a netted area where they become trapped and eventually dehydrate before dying. One significant advantage of this design over traditional wet inverted cone traps is that the flies are contained in a separate area from the bait, preventing an endless cycle of egg-laying, hatching, and maturation that can render even highly effective-looking fly catchers ineffective. This problem can be mitigated by regularly changing the bait, but it's still beneficial to avoid this issue altogether. When emptying the trap, users are left with a batch of clean, dry flies suitable for use in bird feeders or as food sources for fish and reptiles, rather than dealing with a messy, wet maggot problem. To create a version based on a soda bottle, several components must be designed: - A cone made from the top portion of the bottle combined with a printed attachment to prevent flies from escaping - A cylindrical trap area that encloses the cone, featuring various options for support and netting: • Minimal framework supporting some form of netting • Framework attached to a cylinder crafted from cut plastic bottles • Fully printed mesh-like cylinder - Base holding the cone in place while allowing flies to enter, potentially integrated with a bait holder that prevents breeding
