3. The Science Behind Why This Sink-Side Trap Works
The science behind this trap lies primarily in the properties of apple cider vinegar and dish soap. Apple cider vinegar contains acetic acid, which emits a strong, sweet aroma that is irresistible to fruit flies and gnats. This scent mimics the fermentation process, which naturally attracts these insects.
Once the bugs land on the surface of the vinegar solution, the dish soap’s role comes into play. Normally, the surface tension of the liquid would allow the insects to sit on top and potentially fly away. However, the addition of dish soap breaks this tension, causing the insects to sink and drown in the liquid. This combination makes the trap both an attractant and a lethal solution for these pests.
