Does anyone know what the tiny little midges/flies are that hang out around some potting mix? I have my pointsetta and my money plant in the same potting mix, and they both have teensy little flies around them. The flies donāt seem to be on the plantājust the soil. Is it harmful, and will it affect my other plants? Can I treat it with a pesticide? I tried the yellow sticky traps, but they donāt get them all. Any advice is much appreciated!
