Set an apple cider vinegar trap

A simple, effective trap that exploits fruit flies' attraction to the acetic acid in fermented apple cider vinegar. Most kitchens already have everything needed.

Steps

1. Pour about 1 inch of apple cider vinegar into a small jar or bowl.
2. Add 2-3 drops of liquid dish soap to break the surface tension so flies sink on contact.
3. Optionally cover with plastic wrap secured by a rubber band and poke several small holes.
4. Place the trap near problem areas — fruit bowl, sink drain, or trash can.
5. Replace the vinegar every 2-3 days to keep the scent strong.

Why It Works

Fruit flies detect fermentation byproducts in apple cider vinegar from a distance. The dish soap eliminates the surface tension that would otherwise let them land and escape. Maintain traps for at least two weeks to outlast the full breeding cycle.

Tips

• White vinegar does not work — it lacks the fermentation compounds fruit flies seek.
• Multiple small traps spread around the kitchen outperform one large trap.
