A new gardening question of the day appears every day of the year on the front page of Almanac.com. Below is the answer to one of the questions from our Gardening Questions and Answers Archive where you can find over 400 more gardening questions (with answers!).
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?
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.
