Yes, it does! Dr. Killigan performed extensive testing for over a year on this particular product. He and his team found that Sweet Surrender yields catch-rates of up to 10 times those of apple cider vinegar, which is most commonly used to attract fruit flies. This effectiveness can be attributed to several factors. Our unique compound has a more intense odor, the fruity components of red wine, perfect acidity levels, and residual sugars from the fermentation process. It is also engineered to have a fragile surface tension, which means that the bugs aren't able to alight on the surface of the liquid, and are immediately trapped inside.
