Gawd, just heard that "some people" are complaining about gnats in the office (most everyone has individual offices). It's been decided that they're coming from the plants some of us have. Someone had the brilliant suggestion of spraying windex in the soil, but somehow I doubt that's great for the plants. Now there might be something passed down from above.
Chill out people, I have 8 plants in my office and rarely encounter gnats, not even one a day. They're slow and easy to smash. I'd understand if we were talking about big buzzy flies, but we so aren't.
