The answer to 'why is my centipede nests' is that centipedes are common household pests that can sometimes nest indoors. Centipedes are attracted to damp, dark areas like basements, bathrooms, and under appliances or furniture. They are looking for a warm, moist environment to build their nests and lay their eggs.
Signs of a centipede infestation include seeing the insects themselves, as well as noticing their shed exoskeletons or egg sacs. Centipedes can also leave small holes or tunnels in drywall, wood, or other materials as they build their nests.
