Two-Spotted Spider Mite (Tetranychus urticae)

These tiny arachnids thrive in the warm, dry conditions often preferred by Sedum tetractinum. They pierce the succulent cells to suck out sap, leaving behind fine silken webs and causing stippling on the leaves.

Very Common

How to confirm: Hold a white piece of paper under a leaf and tap it sharply to see if tiny crawling specks fall onto the paper.

1 Immediately spray the plant with an organic miticide or insecticide to kill existing spider mites and their eggs.
2 Increase humidity and reduce dry heat around the plant, as spider mites thrive in arid environments.
3 Check surrounding plants and use yellow sticky traps to monitor for any remaining pests.

European Red Spider Mite (Panonychus citri)

While slightly less common than the two-spotted variety, these mites create characteristic webbing on succulents. They tend to cause a more bronzed or reddish appearance to the stonecrop's foliage.

Common

How to confirm: Inspect the undersides of the fleshy leaves for small, reddish-brown moving dots.

1 Isolate the plant immediately to prevent the mites from spreading to other succulents and spray the foliage thoroughly with an organic miticide to kill existing mites and eggs.
2 Gently wipe the leaves with a damp cloth to physically remove webbing and dust, then increase airflow around the plant to make the environment less hospitable for mites.
3 Monitor soil moisture levels closely, as spider mites thrive in dry, stressed conditions; use a moisture meter to ensure the substrate remains appropriately hydrated.
warning

Cheesecake/Mold Mites (Tyroglyphidae)

In cases of high humidity or decomposing organic matter in the substrate, these mites can appear. While they don't typically create large webs like spider mites, their presence can sometimes be confused with silken residue from other pests.

Common

How to confirm: Examine the soil surface and base of the plant for extremely small, white, moving particles.

1 Isolate the plant immediately and treat the surface of the substrate with an organic insecticide to eliminate mites living in decomposing organic matter.
2 Reduce humidity levels and ensure the substrate is not overly saturated to prevent further mite proliferation.
3 Repot the plant in fresh, well-draining substrate to remove any remaining organic debris that serves as a food source for the mites.
