Fungus Gnat Larvae in Orchid Moss: Control with Imidacloprid Granules

Identification

Tiny white, elongated bugs with antennae in sphagnum moss are likely fungus gnat larvae. They feed on fungi and organic matter; heavy infestations may damage roots.

Control

Sprinkle imidacloprid granules on the moss surface and water in. This systemic controls aphids, scales, mealybugs, and fungus gnat larvae.
