I have containers of plants in my office, and they seem to be attracting gnats. How can I get rid of the gnats without exposing my coworkers to insecticides?
Answer
If they are adult fungus gnats (tiny, nervous black flies), drench the soil with insecticidal soap until no more appear. If they reappear, you’ll need to kill the larvae by repotting the plants in clean pots with fresh potting soil.
