Why Do I Get Little Flies Around My House Plants?

You may think that your indoor plants are safe from pests and things that can savage them in the outside world – but there is at least one critter that can still appear!

The fungus gnat is a tiny fly that is drawn to the damp, nutrient rich soil in your house plants.

They look a lot like fruit flies, but they are actually different in their feeding habits as well as their physical appearance.

The fungus gnat feasts on the algae, fungus and even plant roots when they are in their larval stage.

Many plants can handle the root damage, but young or recently repotted plants can have problems because of this.

You will probably find that you have more of a gnat problem if you over water your plants, so keep watering to a bare minimum!

  • Use Neem oil. This natural oil is a great and gentle insecticide. Use 1tbsp of Neem with 1tsp Castille soap and 4 cups of water. Spray liberally all over the soil.
  • Nematodes. Natural predators of creepy crawlies is the best defense against creepy crawlies – try Steinernema feltiae to combat the fungus gnats that you will find in your potted plant soil.
  • Try vinegar traps. Mix a little vinegar with an equal amount of cider in a shallow dish and leave it near the plant. The insects will be attracted but will drown when they get too close.
  • Use sticky traps. Placing these clever sticky strips on or near your plant will catch the adults, thus breaking the life cycle.
  • Repot the plant. If nothing else works, uproot the plant entirely and wash off the roots. Repot the plant in fresh soil, and you should find that there are no more gnats.
