Why does your Capsicum annuum Salsa Deep Orange have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The tiny black flies are likely the adults of fungus gnats, which thrive in the moist organic matter found in pepper potting mixes. Their larvae feed on fine root hairs of Capsicum annuum, which can lead to stunted growth and wilting.
Similar to fungus gnats, Sciarid flies are attracted to the decaying organic matter in overwatered pepper soil. They do not cause direct damage to the plant but indicate a highly humid microclimate around the base of the chili plant.
While less likely to fly freely like gnats, certain aphid species can appear as small dark moving dots on new pepper growth. They suck sap from the tender stems of the 'Salsa Deep Orange' variety, causing leaf curling.
