Apple Cider Vinegar Fly Trap
A simple bait trap that attracts and drowns house flies using fermented vinegar
5 min beginner Yields 2 traps
Ingredients
- 1/2 cup Apple cider vinegar
- 1/4 cup Warm water
- 3 drops Dish soap (breaks the surface tension)
- 1 tbsp Sugar (enhances the fermentation scent)
- 1 small piece Overripe fruit (optional, banana or apple works well)
Steps
- Pour apple cider vinegar into a wide-mouth jar or shallow bowl.
- Add warm water and stir in sugar until dissolved.
- Add 3 drops of dish soap and stir gently. Do not create foam.
- Drop in a small piece of overripe fruit if available.
- Cover the jar with plastic wrap and secure with a rubber band. Poke 5-8 small holes with a toothpick.
- Place near flies: trash cans, fruit bowls, windows, or kitchen counters.
- Replace bait every 3-4 days or when the liquid becomes cloudy.
Why It Works
Apple cider vinegar produces acetic acid and ethanol vapors that mimic rotting fruit. Sugar boosts the scent. Dish soap breaks surface tension so flies sink on contact. Plastic wrap with holes exploits flies’ inability to navigate back out.
Tips
- Place multiple traps in different locations for severe infestations.
- A paper cone inserted into the jar works if you do not have plastic wrap.
- Traps are more effective in warm weather due to increased evaporation of attractants.
- For outdoor use, skip the plastic wrap and use a larger bowl.
