  1. Print Part

    Download the model, import it into your favorite application, and print it with your 3D printer using PETG Filament

  2. Mix bait solution

    Follow the bug-bait recipe. Add the dish soap when you set the trap. For that added kick, add a tsp of beer or red wine to the bait before you add the soap. If you mix a batch recipe, do not add beer or dish soap to the vinegar and sugar mixture; it will sour. Vinegar and sugar mixture should keep in a sealed jar for several months.

  3. Assembly

    Put the bait in the jar, insert the trap funnel, and secure it with the threaded lid ring.

  4. Clean trap and re-bait

    Clean the trap of dead bugs and bait solution every 4-5 days. Wash thoroughly with soap and water. Dry and add more bait solution. Leave the trap in traffic areas such as near the kitchen trash can.
