Answer: Sometimes centipedes are brought in with a plant, they tend to hide in the damp potting soil and feed on the decaying organic matter in it. When you water the plant, the flooding sends them out of the soil. You could dust the soil surface with diatomaceous earth to stop them as they exit the soil. You will need to reapply after each watering. Read and follow the label directions. Also, be sure you are not overwatering your plant. I hope this helps.
