Why does your Aloe aristata have tiny black flies? Diagnose the cause and fix it with our step-by-step guide.
The presence of tiny black flies in succulent soil is most commonly due to fungus gnats, whose larvae thrive in the moist organic matter required by Aloe aristata. The adults emerge to lay eggs in the top layer of substrate, often attracted to the humidity around the plant base.
Excessive moisture in the Aloe aristata substrate creates an ideal breeding ground for fungus gnat larvae and can lead to root rot. As organic matter decomposes due to high moisture, it provides a nutrient-rich environment for fly populations to explode.
If there is fermenting organic matter or decaying plant tissue at the base of the Aloe, fruit flies may be attracted to the site. While less common than fungus gnats, they are drawn to the moisture and sugars present in decomposing succulent leaves.
