Sirka & Dish Soap Fruit Fly Funnel Trap
An inescapable physical trap using fermenting white vinegar and surface-tension breaking liquid soap. The sweet acetic aroma lures fruit flies inward, while the surfactant eliminates water tension, causing flies to sink upon landing.
Ingredients & Supplies Required
- Distilled White Vinegar (सफेद सिरका (Safed Sirka))
1/2 cup
Substitute: Overripe banana peel with water
- Concentrated Liquid Dish Soap (बर्तन धोने का लिक्विड साबुन (Dishwash Liquid))

Precautions & Patch Test Guidance
Do not stir soap into a heavy lather; a smooth surface is essential to break surface tension without alerting flies.
For any topical preparation, always conduct a 24-hour inner-arm skin patch test first. Informational traditional wisdom only—not medical advice. Read full Health Disclaimer .
