2. Paper Funnel Jar Trap
A paper funnel trap uses attractive bait inside a jar and a narrow funnel opening that makes it difficult for flies to leave.
What You Need
- A glass jar
- Apple cider vinegar, fruit juice, or a small piece of ripe fruit
- A sheet of paper
- Tape
How to Make It
Place the bait at the bottom of the jar. Roll the paper into a cone, leaving a small opening at the pointed end.
Insert the cone into the jar without allowing the narrow tip to touch the bait. Tape the paper so the funnel holds its shape and seal any large gaps around the rim.
Fruit flies follow the scent through the funnel opening. Once inside, many struggle to locate the narrow exit.
Who It Suits Best
The paper funnel design is ideal for households that prefer an enclosed trap with less risk of spilling liquid.
Setup Tips
Keep the funnel opening small, but not completely closed. An opening approximately the width of a drinking straw is usually sufficient.
For stronger attraction, combine apple cider vinegar with a small piece of banana.
Benefits
- Reduces the chance of flies escaping
- Contains captured insects inside the jar
- Can be made from recycled materials
- Works with several types of bait
- Easy to place behind small appliances
