The answer to 'why is my centipede infestation' is that centipedes have likely infested your home due to excess moisture, dark hiding places, and an abundance of their preferred prey. Centipedes are attracted to damp environments and can thrive in areas with high humidity, leaks, or poor ventilation. They often hide in cracks, crevices, and under furniture, and feed on other insects, spiders, and even small rodents.
To address a centipede infestation, you'll need to identify and eliminate the root causes by reducing moisture, sealing entry points, and removing their food sources. Regularly inspecting and treating problem areas can help get the infestation under control. In severe cases, or if the problem persists, it's best to call in a professional pest control technician who can properly assess the situation and implement effective, long-term solutions.
