If you are like me and have fruit fly problems every fall, then this trap is for you!

These traps look great and make great gifts! Best of all, they really do work.

*One word of caution, the 3D printed parts are not dishwasher or food safe. Wash in warm water by hand and don’t use with food products.

Fun Facts!

A single female fruit fly is capable of laying hundreds of eggs. Within a week, they hatch into maggots and burrow into the plant matter. After about 5-6 days, the larvae transform into pupae. A few days after that, they emerge as adult fruit flies.

What you will need:

Click on the pictures to purchase the items. 

1. Regular Mouth Half Pint Mason Jars. I like the blue Ball jars because they look nice with blue filament!

2. 3 oz Plastic Cups

3. 3D Printer Filament. I use translucent blue PLA filament because it looks nice with the blue jars and it works great in the trap.

4. The 3D Files. Just click on the images below. You will be directed to our store but the files are completely free. Just add them to your cart and follow the instructions.

5. Apple Cider Vinegar and Dish Soap

Print it, fill it and assemble!

I printed my traps using translucent blue PLA filament. I used layer heights of .2 mm and did not use support material. After printing the trap and plug, fill the 3 oz cup with some apple cider vinegar and a few drops of dish soap and assemble. Sometimes I like to add a few food scraps like tomato or fruit trimmings. You can use the plug to keep them inside the trap while you transport them outside, or you can insert the plug and put it in the freezer to kill them.  Hope it works will for you!

Fun Fact!

Liquids like vinegar have what is called surface tension. This surface tension is caused by the molecules being attracted to each other. The surface tension actually allows the fruit flies to sit on water or vinegar. By adding a few drops of dish soap, you break the surface tension of the liquid. This happens because the soap creates gaps between the molecules reducing their attractive forces.
