Fungus Gnats

These tiny black flies thrive in the moist, organic-rich potting media used for Anthuriums. The larvae live in the top layer of soil and feed on decaying organic matter or, in heavy infestations, can damage developing root hairs.

Soil Moisture Excess/Overwatering

Fungus gnat populations explode when Anthurium soil remains consistently damp. This environment not only attracts flies but also increases the risk of root rot in this species, which prefers well-draining, chunky media.

Very Common
