Is there an effective way to eliminate gnats (indoors)?

We are trying Neem Oil. It seems to help if you use it religiously, every 7 days, to disrupt their lifecycle. It's for plants, but you can rub it on other surfaces where they tend to gather, or dilute it with warm water and spray it on them like regular insecticides. Be sure to test surfaces first, to avoid damage to wood or wallpaper.

Sand gnats? That makes you sound like a bigoted jerk. I am a democrat and I think amnesty is a bad idea for anyone here illegally. Talking about exterminating people though is why people will brush off everything you have to say because it sounds like unintelligent dribble. Personally, I think they all support Bush, because under him they can all be guest workers, and work for less than minimum wage so his cronies can get even richer off the backs of thier slave laborers.
