The easiest way to kill gnats is to use CB 80 and fog the area where you see them. CB 80 is an aerosol spray that is sprayed into the air. It contains natural pyrethrum which is lethal to gnats and all flying insects.
To get control of gnats, you must also find the areas where they are breeding and treat them. Gnats will commonly breed in potted house plant, for which you can use any granular insecticide such as Surrender Granules to get control. Simply sprinkle the granules onto the soil, not the leaves of the plant.
Areas where moisture stands such us under shrubs, decks and other outdoor areas are also prime breeding spots.
Spraying these areas with a residual spray such Bifen Insecticide gives control.
Traps such as the Flyweb Fly Light or the GoldStick will also give some indoor control.
Above all, make sure that you are dealing with gnats and not fruit flies which are different. Fruit flies have large red or orange eyes and are attracted by rotting fruit and garbage.
Hope this helps.
