How To Get Rid Off Gnats In Potted Plants

Besides good weather and fun times, Summer might bring unwanted guests to your green friends like gnats. These annoying but harmless black flies are looking for a moist soil to set up their breeding ground, and they are very active during the warm seasons.

If your plant got them, most likely you have been watering it too often and that is why gnats are totally head over heels for your plant 😀

No worries, this can be easily controlled if action is taken as soon as you see them around.

How to get rid of fungus gnats in 4 steps:

  1. Remove 2"-3" of top soil, top it off with the fresh one. We recommend using Espoma Organic Potting Mix -
  2. Allow the soil to dry out for a few days so the top two inches of soil is dry. Gnats can not survive in dry soil.
  3. Use yellow sticky traps to monitor the population. With traps, you can easily see the results of your efforts + it is good to catch the grown flies before they lay their eggs. You can order it here -
  4. Use GoGnats solution to spray the soil twice a week until bugs disappear. You can get it here -

We strongly recommend getting soil moisture meter. This tool will help you to understand when your plant is ready for a drink and to avoid over-watering.

We sell Soil Moisture Meter in our plant shop and ship them to customers in New York or New Jersey, or you can get one from Amazon for nationwide shipping.

Grab the tools and fight those flies!! I am sure you will win this battle 😀

Window direction is not the only factor to understand your light situation. What is outside the window makes a big difference. Another building, large tree, etc. will block direct light and will effect lighting environment.
