The answer to 'why is my centipede invasion' is that centipedes have likely infested your home due to damp, dark conditions that provide them with an ideal habitat. Centipedes are attracted to moisture, rotting wood, and other organic matter, and they often enter homes through cracks and crevices in search of these conditions.
Common symptoms of a centipede infestation include seeing the fast-moving, segmented insects crawling around, especially in bathrooms, basements, or other humid areas. Centipedes can also deliver a painful sting if handled, which is another sign of their presence. To solve a centipede problem, it's important to address the underlying moisture and habitat issues that are attracting them.
