The latest in plant care tips for keeping your foliage happy and healthy, brought to you by premium plant delivery service Léon & George.

Having some pesty problems around your plants? Fungus gnats are common pests of indoor plants, and though they are not immediately harmful to your plants (or you! They don’t bite), these flying bugs can be annoying and are generally an indication of overwatering.

There are two lifecycles to cover - adult gnats flying around and larvae finding home in the soil. It is the latter that can cause problems and damage your plant’s roots. Here are different methods to control both stages and get rid of gnats once and for all.

  • Dry out soil - Gnats and their larvae need moisture to survive. Try drying out the soil completely before watering again. 

  • Homemade dish soap spray - combine 1 tablespoon of dish soap with a quart of water. Test the spray on one leaf before applying to the rest. 

  • Potato slices - Cut up 1 inch cubes of potatoes and bury them just below the surface. Wait 4-8 hours as it attracts the larvae, then dispose of the slices.

  • The strong stuff - if gnats become a recurring issue, find a solution with Bacillus thuringiensis subspecies israelensis or Bti, which you can easily find on Amazon
