Anecdotal evidence on the killing of gnats

Recently gnats have become a persistent minor annoyance here in San Diego, to me anyway.  A couple of searches suggested to me the home remedy of leaving a glass out with a mixture of cider vinegar and hand/dish soap.  Fortunately I happened to have both components on hand already, because if the suggested remedy had involved getting something specific there’s no way I would have ever gotten around to it.  But this morning before leaving for work I left about three ounces of vinegar with a squirt of dish soap, promptly forgot all about it, and returned home this evening to find three dead gnats submerged at the bottom of the glass.  Victory through firepower!
