I found a really good way to get rid of these little buggers. First, empty your garbage pail out [the kind of pail that has a swing open cover], then place a fresh banana peel at the bottom of it. The gnats will enter the pail through the slits of the swing open cover and go all the way to the bottom of the bucket to get to that banana peel. After a good period of time, GENTLY bring your bucket outside, be very smooth in this motion cause these gnats are fast flyers and will get out of the bucket if it is suddenly jostled. Once outside [close the house door behind you], lift the lid off the bucket. This action will startle the gnats and send them flying out of the bucket in all directions where the real open world with predators awaits them. I've literally cleaned out my entire condo of these gnats with this method, and yes, they are all coming from houseplant soil. GOOD LUCK !!
