Why does your Soleirolia soleirolii 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 thrive in the consistently moist substrate required by Baby's Tears. Their larvae feed on organic matter and fungal mycelium in the top layer of the soil.
Baby's Tears requires high humidity and moist soil, but if the substrate remains waterlogged, it creates an ideal breeding ground for fungus gnat larvae. This environment also increases the risk of fungal pathogens in the root zone.
As the delicate leaves of Soleirolia soleirolii decay, they create nutrient-rich organic debris on the soil surface. This decaying material provides a primary food source for the life cycle of many small dipteran insects.
