All you need is a two liter bottle, and Say Goodbye to Fruit Flies with This Easy DIY Trap


🍌🍾 Say Goodbye to Fruit Flies with This Easy DIY Trap

All You Need Is a 2-Liter Bottle, Sugar, Vinegar & a Banana Peel!

Tired of pesky fruit flies buzzing around your kitchen or garden? Here’s a simple, inexpensive, and chemical-free solution you can make at home using items you probably already have in your pantry.


🧪 Ingredients:

  • 1 empty 2-liter plastic bottle
  • ¾ to 1 cup of sugar
  • ¾ to 1 cup of vinegar (any type works, even cheap white vinegar)
  • 1 banana peel
  • Warm water (to fill halfway)

🧰 Instructions:

1. Prepare the Bottle

  • Rinse the bottle thoroughly.
  • Cut the top third of the bottle off (right where it starts to curve inward toward the neck).

2. Mix the Trap Solution

  • In the bottom half of the bottle, combine:
    • ¾–1 cup sugar
    • ¾–1 cup vinegar
    • The peel from one banana
  • Fill halfway with warm water and stir to dissolve the sugar.

3. Assemble the Trap

  • Invert the top part of the bottle (like a funnel) and place it into the bottom half — neck facing down.
  • Make sure the funnel doesn’t touch the liquid. Tape or staple the edges if necessary to hold it in place.

4. Place the Trap

  • Set the bottle near fruit bowls, trash bins, compost areas, or anywhere you’ve seen flies or gnats.

🐝 How It Works:

  • The sugar and banana attract the flies with their sweet scent.
  • The vinegar adds a fermented smell they love but also acts as a mild preservative.
  • Once inside the bottle, the flies have trouble escaping and eventually drown in the solution.

🧼 Bonus Tip:

Change the trap every 5–7 days or when it gets full. You can rinse and reuse the same bottle.


Why This Trap Is So Effective

  • Non-toxic and safe around pets or kids
  • Made with kitchen scraps and inexpensive ingredients
  • Can reduce fly populations quickly and naturally
