Centipedes are predatory insects that feed on other small invertebrates like spiders, insects, and even other centipedes. They may build nests or colonies to protect their eggs and young. Signs of a centipede infestation can include seeing the centipedes themselves, as well as their shed exoskeletons or egg sacs.
