The larvae of fungus gnats should be very tiny and hard to spot, you only need one fly to get in the house and as soon as it finds wet compost to lay its eggs into they multiply rapidly. Sticky fly paper will catch the flies. Let the compost dry out, place the pot onto some newspaper to soak up excess water. Then only water pots from below, gravel on top of the pot will help cover the soil. The larvae eat the roots of plants, causing most damage to tiny seedlings.
