Got a few (like I see 1, once in a while) fungus gnats. I keep my soil really dry, water possibly 2x a week, so they can't get too out of control. But I got this spinosad, which I am not sure how to apply. I grow in soil, and I would like to use it as a drench, as well as a spray. However, is the spray on the plant that necessary? I am really interested in killing the larvae in the soil...Can I just mix the spinosad to the concentrations given in the directions and just dump it in the soil, or do I have to just spray it?
