Why does your Sedum rubrotinctum have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
Pet FriendlyThe most common cause of tiny black flies in succulents is fungus gnats, whose larvae thrive in the moist organic matter found in overwatered Sedum soil. The adults are attracted to the humidity levels around the base of the plant.
These flies are attracted to the decaying organic matter within the potting mix. In Sedum rubrotinctum, they often emerge when the substrate has become too decomposed or holds moisture for too long.
If there is fermenting organic material or uncleaned debris near the pot, fruit flies may mistake the succulent's environment for a breeding ground. While less common than gnats, they are attracted to high-moisture environments.
