Why does your Calathea insignis have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe tiny black flies are likely fungus gnats, which thrive in the moist, organic-rich soil required by Calathea insignis. Their larvae feed on decaying organic matter and can damage the delicate root systems of your plant.
Frequent moisture in Calathea insignis soil creates an ideal breeding ground for fungus gnat larvae. If the soil stays saturated, it promotes the fungal growth that these flies rely on for food.
Calatheas often use potting mixes high in peat or compost, which provide a nutrient-dense environment for insect eggs to hatch. The breakdown of this organic matter attracts adult flies looking for oviposition sites.
