Millipedes live in cool damp places outdoors, but typically enter the home through basement doors, garage doors, windows, or in crawl spaces vents during migration, or when their habitat gets flooded by heavy rain. Once they are in the home they are usually found in the basement under boxes, furniture, or any cool, undisturbed place but they can be found in any area of the home. Rooms with moisture such as bathrooms, laundry rooms and kitchens can be potential living spaces for millipedes.
