The answer to 'why do I have centipedes' is that centipedes are common household pests that can invade homes in search of food and shelter. Centipedes are attracted to damp, dark areas like basements, bathrooms, and under sinks where they can find insects, spiders, and other small prey to feed on. They may also come indoors to escape cold or dry outdoor conditions.
Seeing centipedes in your home is a sign that you may have other pest problems, as they are predatory and feed on other insects. Controlling centipedes often requires addressing the underlying issues that are attracting them, such as moisture problems, clutter, or other pest infestations.
