Houseplant Gnats

Question:  We've got tons of flying gnats. I don't know where they're coming from, and I don't know what to do to get rid of them. But they're driving me crazy. What do you recommend?
 
NICK: High humidity, wet soil and hot temperatures are perfect for breeding gnats. These are soil borne organisms that come out and they just kind of want to get all on your face when they're there. Oddly enough they are attracted to your breathe.  Regardless, we have to ward them off.  Probably one of the best ways of doing this is taking them outside into a patio area, and spraying them down with an organic Spinosad. Then water the plants outside, when you don't notice them any longer bring the plant indoors.
