Vinegar and Soap for Gnats

Summer is here and one of the mysteries of the ages, at least to me, is why and how those pesky gnats come up out of my drains and potted plants and drive me bonkers. Years ago I read a neat trick to get rid of them. And it truly works. I place a small bowl of ACV and a squirt of liquid soap onto my kitchen and bathroom counters and also the window sill in my master bedroom bathroom where I have some potted plants. The gnats are attracted by the ACV and when they plunge themselves into the little bowl with the mixture they never see the daylight again. Problem solved.
