Gnats in soil? I’m not if the gnats are actually coming from the soil but I’ve seen them in and around my plants.

Question

How do I remove gnats from my plants without killing my plants? Ficus plant is loosing a lot of leaves and it’s my favorite plant.

Answer 1

The gnats are called Fungus Gnats. They are not harmful, and many consider them beneficial.

These insects only come out of the soil when it is too wet, which suffocates them. Their food source is fungus, and rotting roots. They do not harm living plant tissue.

With that being said- I think that your plant is being overwatered. Ficus are notoriously drought hardy (Especially the ornamental indoor specimens) and very susceptible to infection.

As long as you let the soil dry out very thoroughly (let’s say bone dry down to at least 5 or 6 inches) it will be happy, even in lower light conditions. It does enjoy bright but indirect light, though it can’t tolerate full sun for very long.
