Why does your Sinningia speciosa have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe tiny black flies are likely fungus gnat adults, which lay eggs in moist organic matter. Their larvae feed on the fine root hairs of your Sinningia speciosa, potentially causing stunted growth or rhizome decay.
Fungus gnat populations explode when the substrate remains damp for extended periods. For Sinningia species, which require well-draining media, constant wetness creates the perfect breeding ground in the top layer of soil.
A substrate that is too rich in peat moss or compost provides an ideal nutrient source for gnat larvae. If your Gloxinia mix is overly decomposed, it becomes a highly attractive breeding site.
