Fruit Fly Trap Cap for PET Bottles

🪰 Fruit Fly Trap Bottle Cap – Fits Standard PET Bottles

Tired of fruit flies in your kitchen? This simple 3D-printed bottle cap turns any standard PET soda bottle into an effective fruit fly trap in seconds.

Just screw the cap onto an empty bottle with a small amount of attractant inside. The flies are attracted by the smell, enter through the openings, and have difficulty escaping.

It’s cheap, reusable, and easy to print.

🍎 How to Use

1. Take a standard PET soda bottle.
2. Add the attractant mixture:
   • A little apple cider vinegar
   • A splash of sweet juice
   • A few drops of dish soap
3. Screw the fruit fly trap cap onto the bottle.
4. Place the trap where fruit flies are present.

The dish soap breaks the surface tension, so the flies sink instead of escaping.
