The best way to get rid of a gnat infestation in your garden is to use insecticidal soap or horticultural oil. Spray these solutions directly onto the insects, and then cover them with a layer of soil or mulch. Make sure to keep the area moist for about 24 hours so that the solution can kill any remaining gnats.
