Does anybody have an idea on how I can get rid of the gnats in my yard? Its gotten to the point where my family and I can't spend more than five minutes out there. I've tried treating the lawn with an insecticide with my broadcast spreader and it seemed to work against the mosquitos and other bugs, but the gnats are a stubborn bunch - you walk through the lawn and they just swarm.

Any ideas? Either product or household remedy suggestion welcomed.
