Why does your Citrus limon have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
These tiny black flies live in the moist upper layers of the soil and feed on organic matter. Their larvae can damage lemon tree roots by feeding on fine root hairs, potentially leading to nutrient deficiencies.
If there is overripe or decaying citrus fruit on or near the lemon tree, these flies are attracted to the fermentation process. While they don't attack healthy green lemons directly, their presence indicates an environment ripe for decay.
While the adult flies are small, the larvae create characteristic serpentine tunnels inside lemon leaves. The presence of tiny flying insects can sometimes be confused with the adults emerging from pupal cases in the soil or leaf litter.
