What does the smell of vinegar attract?

Attracting Fruit Flies with Vinegar

While people often look for natural ways to keep pests away, vinegar actually works in the opposite direction when it comes to certain insects. Instead of repelling them, the sharp and fermented scent acts like a beacon for fruit flies.

Because these tiny bugs are naturally drawn to the smell of fermenting sugars and overripe produce, vinegar mimics their ideal food source. This characteristic is precisely why many household traps and commercial pest control products rely on a vinegar attractant combined with a physical trap to capture and manage infestations effectively.
