Why does your Capsicum annuum Tango Light Orange have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adult stage of fungus gnats, which thrive in the consistently moist organic matter found in pepper potting mixes. Their larvae live in the soil and feed on decaying organic matter and fine root hairs of the Tango pepper plant.
Similar to fungus gnats, Sciarid flies inhabit high-moisture environments and are attracted to the nitrogen-rich organic components of pepper soil. While less destructive to the plant directly, their presence indicates a substrate that is too damp for optimal Capsicum health.
While not the cause of the flies themselves, excessive moisture creates the perfect breeding ground for fungus gnats and can lead to secondary root rot in Tango peppers. This weakens the plant's ability to support fruit production.
