Are gnats annoying you out in the garden? Well, Sylvana of  'The Obsessive Gardener' found this remedy:

I found my answer - vanilla! Apparently gnats don't like it, and I have some so why not give it a try? I took about 1/8 a teaspoon real vanilla extract and rubbed it onto my neck, ears and forehead, grabbed the camera and went back outside. I was outside for the same amount of time I had been before - no gnats! And bonus, I smell like a cookie!
