Q&A – What are these small black gnats infesting my potted plants?

These are fungus gnats. UT/TSU Extension Agent Celeste Scott says they breed and grow on damp soils. They are a sign of soil that is consistently too wet. The easiest way to get rid of them is to let the soils dry out between each watering. Celeste says she has never had to use a spray to control them.

  1. First I used hydrogen peroxide that is good for fungus then I used BT and their gone after 1 weak I will spray again BT just to be sure I killed the larva.

  2. Ive tried nematodes and yellow traps and they reduce the population but were impossible to eradicate. I think ill work more on bottom watering
