Centipedes are usually found in dark, moist places like basements, bathrooms, and under boxes. They often enter homes through cracks in foundations or gaps around pipes. To reduce their presence indoors, lower humidity, fix leaks, and keep organic debris away from your home. Sticky traps can help monitor their activity. If it becomes a bigger issue, consider calling a pest control professional.
In the end, if you spot one, it’s doing you a favor—so consider letting it stay or relocating it safely.
