Centipedes in Houseplant Soil: Harmless Decomposers

Centipedes in potting soil indicate moist, organic-rich conditions. They are predators of small insects, not plant pests.

Management Options

• Ignore: They aerate soil and control fungus gnats.
• Remove: Submerge pot in warm water to rim for 2 hours; they surface or drown.
• Prevent: Allow soil surface to dry between waterings; reduce organic mulch indoors.

No insecticide needed. Their presence signals good moisture and organic matter.
