Centipedes in Greenhouse Orchid Pots: Harmless Predators

A greenhouse grower finds 3/4-inch reddish-brown, segmented, multi-legged "worms" with antennae in damp orchid pots (fir bark/lava rock) and other plants. They curl into a tight ring when disturbed and flee into soil when exposed.

Identification: Small Centipedes

Jack DeAngelis confirms these are small centipedes (likely soil centipedes). They are harmless predators feeding on small insects and springtails in the moist medium. They do not damage plants.

No Control Needed

Centipedes indicate a healthy, bioactive growing medium. Their presence is beneficial. No treatment required.
